0:03um
0:04welcome everyone uh to foodie natives
0:06webinar revitalizing the naval industry
0:10with last stoma addison manufacturing
0:12um maria could you just make it full
0:14screen please
0:15my name is madeline fire and i will be
0:18the moderator today i am joined actually
0:21as well by our panelists vigilis memphis
0:24from lino 3d and lambros liascovietis
0:28from hull works sa apologies gentlemen
0:31for mispronouncing your names if i did
0:33and good afternoon
0:36so today as i stated my name is madeline
0:39freya i am the english content
0:41specialist for 3d natives which is the
0:43largest international online media
0:45platform on 3d printing available in
0:48five languages
0:50english of course
0:51but also french german spanish and
0:54italian
0:55i will be the moderator of this panel
0:57especially the q a and a reminder
1:00actually to all the participants if you
1:02would like to ask any questions at any
1:05point during the webinar please ask at
1:07the q a button which you will see at the
1:10bottom of your screen it just makes it
1:12much more likely that we will be able to
1:14see
1:15your questions at the end
1:18um and you can ask them at any point
1:20we'll gather them and we have 15 minutes
1:22dedicated entirely to the q a so our
1:24experts will be able to answer anything
1:26you might want to know
1:28uh
1:29and so moving on vigilis maverpulis
1:33again sorry is the manager of the 3d
1:36department of lino sa he is certified
1:39with an msc in electronic and
1:42mechatronic
1:44design he has 24 years of experience in
1:46the medical and printing industry having
1:49worked as a consultant engineer for
1:51delaware imaging techniques developing
1:54banknote security features and as vice
1:56president of sales at smalter
1:58group of companies and for those of you
2:00who might not know lino 3d is actually a
2:033d printing lab located in greece with
2:06an expertise in all up to and all kinds
2:09of additive manufacturing technologies
2:11uh their specialized personnel and fully
2:14equipped facilities managed to develop
2:16and distribute integrated printing
2:17solutions consisting of equipment
2:19applications consumables and services to
2:21customers and professionals in the 3d
2:24printing market focusing on innovative
2:26technologies and new materials
2:29and actually just a little bit of a
2:30change uh kimon won't be joining us
2:32because he had
2:35something come up but let me introduce
2:37you to lambros the eskovitis
2:40sorry
2:41follow
2:42who following a successful career in
2:44banking as a private banker for
2:45refusable banks in greece and luxembourg
2:48became an investment associated for vc
2:50fund and then decided to join the
2:52maritime industry in 2015
2:55um
2:56as
2:56marine activities had been lifetime
2:58hobbies of his the first step for him
3:00was to be head of the marine division of
3:02motor dynamics sa the
3:04uh the exclusive distributor of yamaha
3:06motive for greece bulgaria and romania
3:08for over 50 years in the early years
3:10lamborghs after graduating from athens
3:12college studied business economics at
3:14the university of sunderland and
3:16received his mba from the university
3:18of staff clyde in glasgow and hellworks
3:22is where he is currently working um and
3:25as the sales of marketing director
3:28hellworks is a ship building company
3:30also located in greece which is composed
3:32of professionals with diverse
3:33backgrounds and skills
3:34who combine their love of the sea and
3:37their skills to design and build
3:39seaworthy vessels and provide high-end
3:41boating services
3:42so let's move on to the next slide and
3:44the webinar topic itself so i'm sure
3:48most of you are very aware of this
3:50significant growth that we have seen
3:53in the 3d printing industry in recent
3:55years
3:57what you might be less aware of is the
3:59actual growth of the elastomer market
4:02which is also the material we'll be
4:04focusing on today
4:05um in this graph which is from polaris
4:08market research you can see that though
4:10it the uh the last time the market was
4:12valued at 17
4:14172.1 million usd in 2020 it's actually
4:19expected to grow exponentially with a
4:21cagr of 29
4:24as you can see in 2028 it will have
4:26significantly increased which is only in
4:28a few years and that is actually in all
4:31areas including north america europe
4:33asia pacific
4:34latin america and even the middle east
4:37showing the importance of elastomers in
4:393d printing the reason for this is
4:42because uh a last demand for last time
4:45is has grown as they have exceptionally
4:48good properties for different
4:49applications notably high tear and
4:52abrasion resistance durability and
4:54elasticity um
4:56though this growth might
4:58is more focused in automotive aerospace
5:00and defense and consumer goods maritime
5:02is actually a sector that is rapidly
5:04integrating it and seeing the benefits
5:06of the last 100 a.m which you will see
5:08more of later today and if we can move
5:11to the next slide please
5:14so just quickly before i need to move on
5:16uh the rule of a.m in maritime
5:19admissibly maritime has been a little
5:21slower to adopt am in some of the other
5:24sectors that are using the technology
5:26however that has been rapidly changing
5:29even over the past year
5:31many in the industry are starting to see
5:32the benefits of using 3d printing for
5:35various applications for example spare
5:37parts one example i can think of the us
5:40navy
5:41is actually currently researching
5:43whether 3d printing could be used to
5:45create spare parts on the sea for their
5:48ships meaning that they could carry
5:50lighter loads and have more
5:54availability for spare parts in case of
5:56any
5:57emergencies it's also particularly am is
6:00particularly interesting for the sector
6:02thanks to its flexibility ability to
6:04create lighter more optimized parts and
6:06of course its cost effectiveness
6:09for those reasons we are seeing
6:11increasing r d in the field notably for
6:13today's webinar companies like lino and
6:15heliworks are increasing the use of 3d
6:17printing in greece
6:19in the maritime sector which is a major
6:21hub for marathon as you can probably
6:24guess
6:26and with that i will leave you in the
6:28capable hands of our panelists once
6:30again welcome everyone today's webinar
6:33and let's get started
6:35thank you for joining us today
6:37let's discuss and to understand what is
6:40their lastomer and
6:43what are they
6:45so an elastomer is a polymer with the
6:49property of a
6:50property of elasticity generally having
6:52notably low
6:55young modulus
6:56and high yield strain compared with
6:59other materials
7:01elastomers are best described as rubbery
7:04materials
7:06rubber originally meant
7:07natural rubber later on elastomer became
7:11to the goal used to talk about synthetic
7:14rubber
7:15most rubbery materials are now
7:17considered a type of elastomeric
7:20material
7:22allow me
7:24here to emphasize
7:27that the production of elastomer with a
7:31traditional method
7:32it's a time consuming and expensive pro
7:36expensive
7:38process
7:39so today we'll explore how the 3d
7:42printing can offer unique production
7:46solution
7:48so
7:49we have some livestreamer examples
7:54probably let's focus on type of
7:56elastomers
7:58it's a tpa tpc tpu
8:00tpo tpv or tps and more more more
8:07some examples that is also familiar form
8:09for us all of us is let's say sock
8:12absorbers
8:14or gaskets or impellers
8:17connectors for sure
8:19frame gaskets
8:21pump ceilings
8:23flexible couplings even the plastic
8:26carpets in our house they use an
8:29elastomer material
8:31let's focus on unique properties of
8:34elastomer
8:35which is the unique properties first of
8:38all elasticity or flexibility
8:43flexibility gives to
8:45[Music]
8:46to elastomers
8:49a high tensile stress
8:51strength
8:52and also elongation and break
8:56plus
8:57we have a
8:58tier resistance
9:00or
9:01abrasion resistance
9:05and of course
9:07oil or in some cases any chemical
9:11resistance
9:12depends of the chemical
9:16so
9:17all the above unique properties of
9:20elastomeric materials come to exploit
9:24with the use of a 3d dimensional predict
9:28what is that
9:30first of all is the volume production
9:32without too lick and replacing the
9:36ejection molding
9:38this is the most important
9:40today
9:41of course
9:42probably all of us we know that
9:44[Music]
9:45with the 3d printing we have a
9:47personalization customization
9:51lower density of the part because we can
9:54design it
9:55to have a lower density
9:58the weight of structure
10:00also it's a matter of design that we can
10:02design with a such way to be a lighter
10:07of course on demand parts
10:09and the most important
10:11for the service bureau
10:13services is the low
10:16low material waste
10:20for those who
10:22[Music]
10:23they are not so familiar with 3d
10:26technology
10:27allow me to give a brief description of
10:29its technology
10:33the
10:34oldest of one is the
10:36fdm as we know as a fuse the position
10:41modeling
10:46the filament
10:49is passed through the hot nozzle
10:52and
10:53deposited
10:54in layers creating the desired object
10:59the other technology who actually is new
11:02is the name pam
11:05and
11:06it's a pellet additive manufacturer
11:10in that case the pellets or flex
11:13is extruded through the hot nozzle again
11:17and deposited in layers created creating
11:21also the desired object
11:24the other technology that is a
11:28also
11:30right now old is the sla technology or
11:33stereo lithography
11:36here we have a laser beam that cures
11:39a photopolymer raising
11:42point to point
11:45till creating the desired object
11:49and from the other hand we have an sls
11:52technology this is selective laser
11:54scenario
11:55that the laser beam
11:58fuses a photopolymer powder
12:02point to point again
12:04till creating
12:05the desired object
12:09so
12:103d printing technologies for elastomer
12:13and dlp
12:15so allow me once again to focus on
12:19what is the ddp technology
12:22dlp technology is the
12:24digital
12:26micro mirror device or dmd
12:30which is the core of texas instruments
12:33dlp
12:34projection technology
12:37the dlp chip contains several hundred
12:40thousand
12:41micrometers micro mirrors
12:44excuse me
12:45the micro mirrors can be
12:48individually rotated
12:50in on or off position
12:55in the own mode
12:56the light from the led projector is
13:00reflected
13:01by the lens
13:02causing the photo sd material to become
13:06solidified
13:08so regarding the
13:11method bottom up that we have a printers
13:16with the technology a bottle map
13:19usually has been adapted to small
13:21breeders for prototyping or for the
13:25small production
13:27for functional parts of course depending
13:31of from predator or
13:33from the resin
13:37so the top-down printing
13:41refers usually to the large large
13:44capacity printers
13:46that usually use
13:48a dlp technology
13:50to take the advantage every benefits of
13:54this technology
13:56still reuse and photosensitive
13:59material
14:01and we can see in next slides more
14:04deeply
14:05what is the
14:06top down and what is offered the
14:09top-down tlp pretty
14:12let's to
14:13discuss a bit
14:15about the etec
14:17or any visiotek or
14:19e-tec
14:22the e-tec was the first company in the
14:25world that to integrate dlp technology
14:28in 3d 3d breeding
14:31in the last
14:3215 years
14:36base of this experience and know-how
14:39led here
14:40to build the world's first production 3d
14:44printer
14:45that can handle elastomeric material
14:50the extreme
14:528k printer can produce hydrants
14:56for functional parts
14:59of different size and shapes
15:02taking the advantages the advantage
15:05of benefits that only 3d breeding can
15:10offer
15:12the goal of this machine of course is a
15:14large projection
15:16scale
15:183d breeding
15:19with a volume of 66 liter of resin
15:26here we have seen some
15:28parts which can
15:30be made
15:32of elastomer material
15:35i will focus on
15:38the impeller is the the white one
15:41on the
15:44top
15:45row
15:48perhaps is the most important component
15:52in both
15:53engines
15:55the purpose of the impeller is
15:58to cool the boat engine
16:01by transporting sea water
16:04in the engine
16:06that means
16:07this part
16:09can be
16:10stay
16:11and
16:13operate in a very very harsh environment
16:20right now
16:21if someone wants to produce all this
16:24part
16:25should be invest a lot of money to
16:28produce a mold and to
16:33time to wait i don't know how many
16:35months to produce the malt and then to
16:38starting to produce part
16:40part by part or one part with a
16:443d printing we can print it on demand
16:46just one part
16:50so
16:52elastomer
16:54industries of elastomer
16:56it is of using elastomerics
16:59more or less everywhere
17:02is a construction industry oil gas
17:04industry
17:06coding industry consumer goods industry
17:10sports
17:11automobile medical
17:13electrical
17:15if we see around you can see in our
17:18house on our office you can see many
17:20many elastic material or elastomer
17:23material
17:25in that case in in this presentation we
17:27will focus on
17:30marine industry
17:33let's discuss first of all just a bit
17:35from our
17:36area in greece
17:38in greece we have more than 5 000
17:41islands
17:43and maritime market
17:45is a larger industry and will have many
17:48small and large shipyards
17:55a last america
17:57can
17:59they can take all these advantages
18:02like a rabbit manufacturer customization
18:04design followed data
18:08material and running aging
18:10abrasion and tea resistant
18:12or in the math and demand
18:15products and to try to
18:19to adapt on marine industry
18:23that's why we decided to work with one
18:25of the best shipyards
18:27in construction of luxury inflatable
18:31boats
18:32halliworks
18:34we asked them to suggest us
18:37some of the parts that are made of
18:40elastic material
18:42and that they believe we will help them
18:46in their production
18:49they choose
18:50to print not the luxury or fancy
18:54ancesory that
18:56hal works usually puts on their boats
19:01but they choose those that are
19:03constantly enhanced environment
19:06and in coda with the salt water
19:11some of this
19:13will be present by hal works executives
19:17my friend labros
19:19in the next slide
19:23so hello and welcome from my side so
19:27thank you van gaalis for the for the
19:29nice presentation so far
19:31um
19:32let me tell you very quickly that
19:34we build our boats
19:36out of grp
19:38that is glass reinforced polyester
19:41if you haven't come across it
19:44uh so grp
19:46is the core material of the boat
19:49however once the hull and deck are
19:53built and glued together
19:55we start installing
19:58other parts
20:00whether that is the console or smaller
20:02parts like handlebars like
20:06other parts as you see here a deck drain
20:10what what a deck train does is just a
20:13hole on the boat
20:15on the deck of the boat
20:17which allows for all the water that
20:19might come in
20:21uh from let's say a large wave or while
20:24i don't know cleaning the boat or
20:26whatever
20:27so uh the deck
20:29gets to drain
20:33that's that's why we need an outlet like
20:35like the one you see here
20:37uh
20:37so that's at the back part of the deck
20:40uh as the water comes in uh it flows
20:43to the back of the deck and then out of
20:45the boat through the string
20:47um the material we we were using so far
20:51was out of stainless steel
20:53why because obviously it's easy to make
20:56and design and easy
21:00to uh
21:02to to to install in a place where where
21:05there's a lot of salt water
21:07uh as stainless steel is is quite uh
21:10durable in terms of corrosion however
21:14uh there's so many limitations
21:17in using stainless steel that's why we
21:19started thinking about what other
21:21materials we could use
21:24which
21:25will be
21:27sustainable
21:28because
21:29we don't want to pollute the environment
21:31anymore
21:33which will be durable which will have
21:35all the properties that we need
21:38to make sure
21:40first and foremost that the deck drains
21:42and then
21:44obviously that
21:45we don't have to replace it every now
21:47and then
21:48we don't have
21:49uh our customers coming back and saying
21:52you know
21:53it's all good but the small parts that
21:56we don't like um
21:59that's how that's how we came across uh
22:01line of 3d and asked them to produce
22:03this key piece
22:05for us
22:07so uh now
22:09all of the parts that can be 3d printed
22:11[Music]
22:13with elastomers are fully customizable
22:16they're
22:17quite quick in in manufacturing
22:19and
22:21we are sure that
22:22we won't get any issues with the
22:24saltwater
22:25which is you know
22:27kills everything
22:28in terms of materials and i'm speaking
22:30of course
22:35as you can see here on on both pictures
22:39we we're practically talking about two
22:41parts
22:42uh
22:43the first part which which has a
22:44rectangular shape
22:46um
22:47is what you see on the deck
22:49and then behind it
22:52is what we will see on on
22:54on the next slide uh all the one after
22:56in fact
22:58um
23:00which is the value so
23:02let's move on to the next part and then
23:03we will come back to the tech train
23:05uh maria
23:07please
23:08uh vangelis can you can you explain a
23:10little bit about the material we use for
23:14draw material that we use
23:16so yeah in that in that case we're using
23:18adaptive 3d elastic tough rubber with
23:21the sword 70
23:23in order to produce
23:25[Music]
23:26the the part
23:29characteristic of the material you can
23:31see
23:32over here and of course you are using an
23:36extreme 8k printer
23:39next slide
23:41excuse me
23:42yeah i was saying the the the different
23:44types of raw materials are different
23:47hardnesses of course the one we chose
23:49for this application
23:51that's the most suitable one
23:53yes of course of course
23:56okay
23:57let's move on
23:58if we may
24:01that's that's another small
24:03piece that
24:05it was troubling us a lot
24:07it's a simple thing it
24:10it's a knob to to a small hatch
24:13[Music]
24:15clearly this knob doesn't turn you just
24:18use it to pull out the hatch
24:21so it's nothing really fancy however
24:26when you build
24:27custom boats it's nice to have small
24:29parts with your logo
24:31or make it even more personal for the
24:33customer if you wish to
24:36so on the left picture
24:38on the picture on the left you can see
24:39that
24:41we're using both plastic
24:43and stainless steel uh
24:47what it means is two suppliers then
24:50someone
24:51at the boatyard who will bring these two
24:53pieces together
24:55uh
24:56create the knob then and
24:59install it
25:01on the hatch
25:04clearly an easy solution would be to
25:06have the knob ready
25:08skip the part of assembling the knob
25:12and moving on to uh
25:15installing it on the boat
25:17that's as we did again with lino 3d
25:20we recreated the knob the design of the
25:22knob and had it printed
25:25using elastomers
25:26um so now
25:29it's even more durable than the previous
25:31one
25:33there is no stainless steel part which
25:35may or may not come off
25:37at any point
25:38or it may corrode
25:41or anything like that so
25:43it's personal it's customizable it's
25:45easy
25:46and fast to produce
25:49la bros how many how many knobs you have
25:51in your
25:53small boat not the big one
25:57roughly well
25:58for this specific cash there's two knobs
26:01uh on every boat and we built 40 bucks a
26:04year so we're talking uh 18 knobs
26:07okay
26:09all in all uh
26:10and of course we uh
26:12as we come up with new designs and new
26:14hatches
26:16we may even use it further
26:18on another part of the boat so
26:20they can multiply easily
26:23okay okay in that uh
26:25imagine uh just uh sorry to interrupt
26:28just imagine the situation where you get
26:3080 plastic pieces of this this knob and
26:34then another 80 stainless steel parts
26:38as you see them their laser cut and then
26:40you have to
26:41put them all together glue them together
26:43and then install them on the boat
26:46we're talking about
26:48a week's work for someone
26:50which is a complete waste of time only
26:52from 18 pieces
26:54just for making one knob and many more
26:56pieces on the boat
26:59many more handlebars many more
27:01latches many more
27:05i i cannot even begin to to to listen
27:08to way too many
27:10uh let's move on a little bit in uh the
27:13next page marilyn if there are any
27:14questions we can come back to those so
27:16for the notebook we used a harder
27:19material with a shorter 90
27:22characteristics of what we can see also
27:25over here still we use the same matin
27:29mass machine
27:30extreme ak
27:33the
27:34if you want to swap material in this
27:36machine
27:37it is
27:39let's say easy
27:41uh
27:43and we are able to let's say to choose a
27:46different material depends of request of
27:48our customers
27:52so yeah
27:53yeah
27:55this is the
27:56lateral part of the deck train we were
27:59looking at earlier
28:02what this piece does is
28:04it is added
28:06to to the rear
28:08of of the deck drain we saw
28:12and it's just a simple one-way valve
28:14that allows the water to come out
28:16but not back in again
28:20it's
28:21quite simple as as a solution
28:24yet really super important because you
28:27never want the water coming into your
28:28boat
28:30um
28:32so
28:33what we managed to do through through 3d
28:35printing
28:36is obviously to improve the design
28:40because there are limitations to what
28:41you can do with stainless steel
28:43and then
28:44attaching parts to it because
28:47the little piece you see
28:50the lighter color
28:51almost white
28:54it always
28:56it's always plastic it's always from an
28:58elastomer or some material of this kind
29:00it can never be stainless steel
29:02so
29:03no silicone yeah
29:05uh so you you always have to make sure
29:07that you
29:08uh attach it properly
29:10to the stainless steel
29:13rubber
29:15tube that you see there so doing that to
29:18to an elastomeric tube is quite easier
29:22the materials come together more
29:25more nicely and then
29:28it's also
29:30a matter of corrosion like we discussed
29:32earlier you never want metal scrolling
29:35on your boat
29:39why because especially in this part uh
29:42salt water is always present
29:44uh in the sense that it comes
29:46backwards and forward
29:48and uh there's always a little bit of
29:50salt water left there
29:52so uh corrosion will be instant
29:54if you don't use the proper materials
29:57and that
29:58sort of elastomer is our best case now
30:02that's why that's why it's the most
30:05challenged part that
30:07you're giving to us is this labros and
30:10indeed
30:12let's say we were thinking seriously
30:16which material we will use and finally
30:19we decided to use an elastomer and
30:22we are right we make a good decision and
30:26we'll be let's say
30:29present in your boats for i don't know
30:31how many years
30:34without that's true that's true you know
30:36making the the making the easy parts is
30:39always
30:40like a simple handlebar or a
30:43a simple
30:46i don't know thing that is just going to
30:48be a decorative like
30:52a cup holder or something like that
30:54that's easy
30:56what is difficult and needs engineering
31:00is getting to this stuff
31:02which is of importance to uh
31:05to properly floating boat and
31:08unsafe boat of course
31:11of course
31:13that's
31:14pretty much it about the parts we did so
31:16far
31:17we have more and more lined up uh
31:20testing all the time and
31:22going back and forth until we reach
31:26a final design and and
31:29and of course a final production method
31:32that is beneficial to everyone involved
31:37so yeah
31:39that's pretty much it and of course we
31:41have for you also the parts that are not
31:44included on this presentation that is a
31:46shock absorber of the
31:48of the engine
31:49plus some okay yeah yeah yeah
31:53also plus
31:54some
31:55customized
31:57key ring with
31:59a name of the lucky
32:02owner new owner of the boats
32:05well if we have if you have a minute to
32:07spare i'd like to talk about that
32:12it's always an issue with with keyrings
32:14on boats on open boats up to 10 12
32:17meters
32:19where you are in contact with the water
32:21it's not a yacht
32:24but it's not
32:26it's it's not a keyless boat anyway so
32:29you have to have your keys
32:31attached to something
32:33uh preferably something that floats
32:36uh but it definitely has to be good
32:38looking
32:39why because
32:41as you get off the boat and onto a
32:44little harbor or beach or anything you
32:46have it with you
32:47so we needed something custom and
32:50there was no way we could find something
32:52good looking
32:54and with the right properties they won't
32:56be
32:57uh
32:58it won't polymerize with the with the
33:00sun
33:01it won't be affected by salt water
33:04um
33:06and nothing out of these foam materials
33:08or any of these used so far
33:10are good looking or can be shaped in
33:12into nicer shapes rather than round
33:15rectangular simple shapes
33:19so that was uh
33:22the idea we had is to have a our
33:24in-house designer design
33:26uh
33:27a key fob
33:28sort of a car-like key fold
33:31and then asked vangelis if he if he
33:33could 3d print it
33:36and of course make it personal again by
33:38adding
33:39uh
33:40leaving a small space we can add the the
33:42name of the boat
33:43or whatever our customer decides uh to
33:46have it marked as
33:48um
33:49so i'm really really curious to see that
33:51in the in in the coming days
33:54i saw the 3d design
33:55i was part of it that
33:57you know having the real thing in your
33:59hands
34:00uh is what i'm after now
34:02i hope we will be able to present it in
34:05the next
34:07webinar
34:09to be nice
34:12to to seeing the people more challenged
34:14and the more fancier luxury
34:17parts not only
34:19functional not only hardcore engineering
34:21yeah yeah yeah yeah
34:23correct correct
34:24make it make it more more fancy too yeah
34:27yeah yeah yeah let's focus on the next
34:28step on the fast fancy parts
34:32next time that there will be
34:34so uh i think there's there's another
34:36slide with the properties of this
34:37material
34:39yeah it's the material we choose a 90 uh
34:42sure more hard and also this material
34:46we want to be
34:48[Music]
34:49totally totally
34:52follow your specification
34:54that
34:56you gave to us about the one-way valve
34:59and how to react with the water and all
35:01these things
35:03i thought passed this test and
35:08we were happy both of us were happy i
35:10thought
35:12next slide maria
35:15so
35:16thank you very much
35:19yes thank you
35:21yes well
35:23please
35:24no no please please it's you
35:27i was just gonna say thank you to both
35:29of you for the panel as i mentioned
35:32before while we're a little early but we
35:34will open the flow up to questions
35:37i see that there are already some i'm
35:40actually just going to ask the one the
35:42two that are in the chat right now so i
35:44don't lose them already
35:46um but feel free to ask questions as we
35:49mentioned in the q a and also vote for
35:51which questions you would like answered
35:53so i am going to start with the
35:54questions from delevina
35:57uh first which is why do you think that
36:00the maritime industry has taken longer
36:02to embrace a.m
36:06excuse me
36:08that's probably for for me to answer i
36:12guess
36:13um
36:15why why because
36:16[Music]
36:18it depends i mean
36:20for us
36:22building smaller boats uh like i said
36:24earlier
36:2510 to 12 meters
36:27maximum
36:30no one is really interested in new
36:31technologies
36:34they know a way that works
36:37and they stick with it
36:39for as long as they can
36:41why
36:42simply because our our production
36:43capacities are small
36:45like i said we produce uh 40 volts a
36:47year
36:48some other greek years produce up to
36:5150 55 maybe even 60 votes a year
36:55so
36:56rnd in general
36:58is
36:59quite focused on making the boat look
37:02better or even make the hull faster
37:06rather
37:06than using new technologies for smaller
37:10parts
37:12so i think you know small production
37:15small sector
37:16not
37:17too much
37:18r d because of uh
37:22simply lack of resources
37:25i think it also probably makes sense
37:27it's one of the most ancient
37:29of the sectors we have that they'd
37:31continue doing what they've always done
37:34there's always room for more innovation
37:36um so and then the next question um
37:39which is would you say that dop
37:42so digital light processing is the most
37:45common technology used in maritime if i
37:48know that you both use it but
37:53let me answer
37:54[Music]
37:57no i thought this
37:59has to do with
38:02with a new visiotek or excuse me e-tech
38:06that has collaborated with the
38:09experts on the fields
38:13that can produce
38:15a very very special material
38:18and use material
38:21that
38:22they are not
38:23aids
38:25during
38:27exposure sunlight or in gas environment
38:31that is it's a matter of let's say
38:34know-how of
38:35e-tec
38:37and
38:38experts of the
38:39[Music]
38:41companies that they collaborate
38:46that makes sense
38:47um
38:48okay thank you
38:50and now i will move into the q a i
38:53believe we should have time to answer
38:55all of them but feel free to keep adding
38:58them and also as you can see on the
39:00screen if for some reason your questions
39:02are not answered do feel free
39:04to
39:06contact either vigilance at lino or
39:08lambros at whole works and they can
39:10answer your questions later
39:12on um
39:14so just moving into the first question
39:17uh what is the cost of production of the
39:20knob
39:21compared to
39:22the conventional one with the laser
39:24cursor
39:27of course
39:30first of all depends on the quantity
39:32[Music]
39:35but
39:36for sure the cost
39:39probably will be
39:42half
39:43yeah that was i was going to say the the
39:45conventional one with
39:49with pvc and and
39:51stainless steel is probably double
39:53yeah
39:55what were 3d printing yeah
39:57i mean that's a significant difference
40:00and and that does not include the uh the
40:02label cost for assembling it
40:04putting together
40:06the plastic part and the stainless steel
40:07on it
40:09okay so actually quite significant
40:11savings uh which well i thought we could
40:13kind of expect with am but always
40:15interesting to hear
40:16and then actually another question about
40:19a part for either one of you is if you
40:22retain the silicone flap in your printed
40:24elastomer one way valve is that because
40:27there is no satisfactory printed
40:28material that satisfies requirements of
40:30both flap and valve housing
40:35so basically why
40:37retain the silicone flap
40:40that's too technical for me bengali if
40:42you can
40:45though it's also possible to print with
40:47silicone
40:48depending on what it is it's not
40:50impossible to print the silicone and try
40:52to understand
40:54let's say to give to him
40:56a proper question
40:59no it's not
41:01actually the reason that we choose this
41:04material it's
41:08on the original there is a two different
41:11two different materials one is the
41:13stainless steel
41:14the second is the silicon and the third
41:16is the spruce
41:18with this way where that's what we
41:21designed and we choose this material
41:24uh we believe that uh
41:27it's
41:28better
41:29and
41:31it's better it's more safe and
41:35this is my question
41:39okay
41:42okay so it's safe first so that's the
41:44reason why you keep it
41:47that makes sense
41:51okay
41:52well thank you that does make sense and
41:55moving on um another question is what is
41:58the difference of using dlp versus
42:01sls
42:02by meaning of elasticity and percentages
42:05and can you give a budget cost it says
42:08of this part but i'm not sure which part
42:11he is referring to
42:13but if you could explain
42:16dlp dlp is the
42:19actually
42:21it's a matter how you how you slice the
42:23part with the dlp technology you are
42:25breathing
42:27layer one layer at once that means you
42:31you slice the the
42:33your file and you project
42:36the
42:38a whole image on the built-in area
42:41on the sls technology you are just
42:44spreading point to point
42:46the quality of the dlp
42:48it's comparing the sls is a day and
42:51night that means
42:53with sls technology with dlp technology
42:57you are not able to see
42:59the lines
43:01and when i say
43:03dlp technology i mean any visual tech or
43:06in tech technology you know you cannot
43:08see the lines of separation from the
43:11other hatters or less
43:15the part is not so let's say need to be
43:19one good pre you predict need to be
43:24finishing when you finish the part
43:27uh regarding the cost did they mention
43:30the cost or not
43:32they asked about the cost though i'm not
43:33sure for which part they were referring
43:37me also
43:38i will say about cost of uh
43:43of the
43:44dlp
43:45i thought it's a much much cheaper due
43:49to the production time comparing the sls
43:53technology
43:54dlp it's 10 times faster than
43:58at least
43:59than sls technology
44:03okay
44:04yes
44:05significant benefit of using the
44:07technology i'd say
44:09okay well thank you and then moving on
44:12um
44:13oh well someone
44:15so what the next question which just
44:16suddenly got more upvotes is how does
44:20the am deck drain compared to the steel
44:22deck drain in regards to manufacturing
44:25cost production time and
44:27possible reduction of parts
44:32again
44:33production cost
44:35i would say
44:37should be half
44:40roughly
44:42and then
44:44production time
44:47i think it's it's way faster uh i don't
44:50have exact times to to put
44:54it's so much faster than galileo and and
44:57unfairly and assembly also
45:01yeah i mean assembly is also faster yeah
45:03yeah yeah it's
45:04faster
45:05but they don't have exact times i i i
45:07don't know if if one thing takes one
45:10hour then how long
45:12the printer takes to print it and i i i
45:15don't know
45:16but uh yeah
45:18it's definitely fascinating
45:20copenhagen the original one that is on
45:22the left side then the
45:26additive manufacturing of the right side
45:30it's a night in metal uh night and day
45:32or
45:33also
45:35the the
45:36the left side are produced
45:38i don't know how many ways we said you
45:41should
45:42take the metal uh glue it uh iron
45:47[Music]
45:48it's
45:49i don't know it
45:51needs days to produce this
45:53with active manufacturers hours
45:56exactly
45:58it's a lot faster and then
46:02stephen is also asking
46:04uh production and possible reduction of
46:07cars
46:09yes reduction of parts in the sense that
46:11the 3d printed uh
46:14part is
46:15is one part whereas the the stainless
46:18steel is a few of them
46:21glued together
46:22so
46:23yes
46:27of course so
46:30also not for us it's in terms of
46:32production of the parts
46:34this has nothing to do with us we
46:35receive one point in both cases
46:38so
46:40but yes production-wise yes
46:43for whoever produces this part
46:47also katie asked about can the elastomer
46:50be available in store 11 or 45
46:53question is
46:56even if if i'm not qualified to ask to
46:59to
47:01to ask to give you an a question to to
47:04answer you but i thought in the near
47:06future will be available
47:08a lot of different
47:10shore material
47:12for elastomer
47:14okay and actually another question from
47:16kt which is is there any shrinkage in
47:19the final product
47:21of course not
47:22okay and then
47:25of course not
47:29actually what is the 3d printing and
47:31also the dlp technology
47:33nothing to do with the scenery or
47:36with
47:38no sls also the same
47:41actually the scenery we're not seeing
47:43the parts
47:44where design the cad files we slice it
47:47we send the machine and we print it one
47:50by one there is a factor uh slight
47:54factor
47:55but usually during slicing and before
47:58you send it to the machine
48:00we know exactly
48:02the three gates of material if any
48:06and the final parts are corrected
48:10just imagine that the same machine
48:13smaller or
48:15bigger machine from any visiotek or
48:18e-tech they offer
48:21dental or medical
48:25applications
48:27that means should be very very very very
48:30accurate by using exactly the same
48:33technology
48:35okay
48:36well we'll be looking forward to seeing
48:38that
48:39um so we have
48:40about six minutes and we have about
48:42three questions i think we have enough
48:44time to get to all of them um so the
48:46first one that i noticed was
48:49well i'm assuming it's for you lembros
48:50actually it's are you seeing greater
48:53adoption of the technology a.m in
48:55shipyards and what do you expect to see
48:58in the coming years
49:02of course
49:03of course general speaking from attitude
49:06manufacturing yes
49:08yes is the future
49:11yes
49:12is the future
49:16we have many requests
49:19with open mind companies like hal works
49:23that
49:26push us
49:28to
49:30show them
49:32[Music]
49:34final
49:36faction and 3d parts not only from
49:39plastic because we offer also a metal
49:42ceramic a lot of material in our lab and
49:46we have let's say many many requests
49:48from different kinds of materials and
49:51we hope or we are sure in the near
49:54future
49:56maritime industry or ship gas will be
49:59let's say move totally on 3d printing
50:06thank you
50:07well i mean i agree but this is also my
50:11industry so i might be biased
50:13um and then another question is where do
50:18you see the most added value for am in
50:21the maritime sector oh
50:24first of all uh
50:26production time
50:29yes in some time course
50:31uh if we're focused on the mold of if
50:35you're focusing the multidisciplinary
50:37excuse me libra excuse me
50:40if we focus on the multi-industry and
50:43this get discussed nothing from
50:45elastomer material or general speaking
50:48property breeding
50:50the multi industry is the biggest and
50:53most expensive part of
50:56shipping yards
50:58or maritime industry
51:00there is they they invest a lot of money
51:03and they're waiting
51:05months
51:07with 3d breeding
51:09the months
51:11are
51:12come at days
51:14and
51:15the price
51:16are
51:19more or less also half but the goal is
51:24delivery time
51:26days
51:27not months
51:28two days three days week
51:31not
51:32two months three months or five months
51:35just a week
51:39is additional of the resistance to cars
51:41environment or
51:43their other major requirements or
51:45regulation required of material for
51:47maritime usage
51:49uh that would be the next question so
51:51just so i can read it just in case
51:52anyone hasn't seen it in addition to the
51:54resistance to the harsh environments are
51:56there other major requirements and
51:57regulations required for materials for
51:59maritime usage
52:03no at the moment uh
52:05there are no specific regulations uh uh
52:08unfortunately
52:09uh
52:10what we do when boat building in general
52:13uh is not so green
52:17uh
52:18if if i understand the question
52:19correctly
52:21it has to do
52:24ah no i'm sorry i i reread it um
52:28it's a regulation we're talking about
52:30yeah
52:37yes
52:39and requirements you know like you'd
52:40have an aviation for that if there are
52:43similar requirements beyond that in
52:44maritime is how i understood yes well
52:47obviously
52:48there are no specific regulations
52:51uh
52:52but imagine that
52:54every boat builder for example
52:57puts his
52:59his signature uh
53:01down to the fact that
53:04the boat
53:05will drain
53:07from the water coming in and that the
53:09boat will be structurally
53:12sound
53:13so
53:16it's it's not only a matter of
53:17regulations it it's how you feel of of
53:21working on something that
53:23will actually carry people
53:26on the water
53:28and
53:29so so it's both a matter of regulations
53:32and an ethical issue as well
53:35so yeah
53:37if we can
53:39[Music]
53:41uh if we can start using materials that
53:43are more
53:45um
53:46adorable and and
53:47we can be sure that uh there won't be
53:50any
53:51any issues with them uh
53:53also further in time that we
53:56that we can say about stainless steel or
53:58the materials we use so far
54:01um then i think it's a it's a win-win
54:03for everyone
54:07it's not just about cost we just keep
54:09mentioning cost and it came up in a lot
54:11of questions but it's not released about
54:13cost
54:14no of course safety
54:17is always very important durability
54:19other factors well that was the final
54:21question and perfect timing actually
54:24because it is just hit 5 p.m cst so with
54:27that i will say thank you both of you
54:30for attending today uh it was a pleasure
54:33having you both
54:35we hope to see you at the next webinar
54:37have a great evening day
54:39depending on where you are
