Full transcript

1. 0:00It’s been over five years since I
2. 0:02first made a YouTube video. And today,
3. 0:05I want to refresh my first video and
4. 0:08explain from scratch, for absolute
5. 0:11beginners, how to use one of the most
6. 0:14powerful, affordable, and personally my
7. 0:16favorite software for digital dentistry
8. 0:19: Blender for Dental. Stay tuned
9. 0:22because today I’m going to teach you
10. 0:24how to get the most out of this
11. 0:26software starting from nothing and how
12. 0:28to prepare models for 3D printing in
13. 0:30minutes. Hello everyone, Juan González
14. 0:32from Odonto 3D courses. I’m very
15. 0:34excited to revisit this topic, as the
16. 0:36original tutorial still gets comments
17. 0:39and things have changed quite a bit
18. 0:41since then. So today, I’m going to
19. 0:44show you the updated, new version,
20. 0:47which will likely remain the same for a
21. 0:50long time. And let’s start once and
22. 0:52for all with the simplest thing, which
23. 0:55is the installation. I’m going to go
24. 0:57to blenderfordental.com, and the first
25. 1:00thing I need to do to install this
26. 1:03software is download what we call the
27. 1:06UI, or user interface, which has a
28. 1:08version under this button that says "
29. 1:11installation," with a version for Mac
30. 1:14and a version for PC. Let me zoom in.
31. 1:18PC and Mac. And basically, it just
32. 1:21downloads the appropriate installer,
33. 1:23and once downloaded, you’ll see a
34. 1:26file like this one. Double-click to
35. 1:29install, accept. Next. Next. Install.
36. 1:32It’s that simple. Well, I won't go
37. 1:34into much detail because this is
38. 1:36something I already explained in an
39. 1:38update to this video right here. So,
40. 1:41it’s basically a very easy installer,
41. 1:43as you can see: next, next, next. And
42. 1:44that’s it. And now it’s going to
43. 1:47launch the user interface. When I press
44. 1:49"launch" here, it will open the user
45. 1:51interface. Now, to use it, you need to
46. 1:54create an account with a username and
47. 1:56password. So right here, I have the "
48. 1:58sign up" option, which allows me to
49. 2:00create a username and password. You
50. 2:02enter all your details here and press
51. 2:04submit, and you will have created a
52. 2:06username and password. Now I’m going
53. 2:09to log into my account so you can see
54. 2:11how to access the modules. You’ll
55. 2:16notice that in the top right corner, my
56. 2:18account is there, and if I go to "My
57. 2:20Modules," all the modules I’ve
58. 2:21purchased will appear. If you haven't
59. 2:24bought any, instead of this green check
60. 2:26, you’ll see the option to buy, which
61. 2:28will take you to the store page, where
62. 2:30I’ll also leave an affiliate link
63. 2:32below. If you want to support the
64. 2:34academy, please use that link to make
65. 2:36your purchases. It doesn't cost extra,
66. 2:38but you'll be supporting the channel.
67. 2:40Well, this module, for example, which
68. 2:43is the one used to prepare models for
69. 2:453D printing, costs only 9. But stay
70. 2:48tuned, as I'll explain how to get it
71. 2:50for free for 14 days so you can try it
72. 2:53out and see if you like it and adapt to
73. 2:55what I'm about to show you. So, you go
74. 2:57here to page six and instead of buying,
75. 2:59you simply register your details,
76. 3:01select the one that costs zero, which
77. 3:03is the trial version. Make sure you
78. 3:05select the right one, click "buy now,"
79. 3:08and it will basically allow you to
80. 3:11choose the same one from the list again
81. 3:13. Which is right here. I click select,
82. 3:17and here you basically enter your
83. 3:19details, and even though you aren't
84. 3:21going to pay, it asks you to fill this
85. 3:23out, and that's it. Click accept, and
86. 3:25you're done. Anyway, I don't want to
87. 3:27dwell any longer on this installation
88. 3:29topic. If you have trouble, you can
89. 3:31write to "Let's Chat" and speak in
90. 3:32Spanish with the Blender for Dental
91. 3:34tech support team if you can't get
92. 3:36something to work, but as you can see,
93. 3:38it's very easy. So, once you have the
94. 3:40module, go here, enter your details,
95. 3:43email, and password, and log in so that
96. 3:45the module appears here. Once you log
97. 3:47into your account, all the modules you
98. 3:49have installed will appear. In this
99. 3:51case, I have all of them. And here next
100. 3:53to Model Designer, there's a button
101. 3:55that says "install," similar to this
102. 3:57one; I already pressed it to speed up
103. 3:59this video. And it will download the
104. 4:01file from the internet. It takes a few
105. 4:03minutes to download, and once installed
106. 4:05, it will identify if I already have
107. 4:07Blender installed. Since I don't have
108. 4:09it, I go to this button that says "
109. 4:11install Blender," and it will also
110. 4:12download the correct version of Blender
111. 4:14to install it. If for any reason you
112. 4:16already had Blender for Dental before,
113. 4:19or you installed an old version or
114. 4:21whatever, delete everything and don't
115. 4:23complicate your life; delete everything
116. 4:25and do exactly what I'm showing you
117. 4:27from scratch so you can install it
118. 4:29correctly. Right now, it's downloading
119. 4:31Blender. I'm going to skip the video
120. 4:33and install Blender by clicking next,
121. 4:36next, next, exactly as it comes out of
122. 4:38the box. Done, the installation is
123. 4:40finished, and now it asks if I want to
124. 4:42know more about Blender; I'll say no.
125. 4:45And now I'll go to the user interface
126. 4:47and hit the "refresh" button so it
127. 4:49recognizes that it's installed and that
128. 4:51everything is fine; everything gets a
129. 4:53green check mark here. It even tells me
130. 4:56Spanish isn't selected. I'm going to
131. 4:58set it for now, and I recommend you do
132. 5:00this, especially if you're having
133. 5:02issues, I'll leave it in English.
134. 5:04English is the default language, and if
135. 5:06there's a translation error, it
136. 5:08sometimes causes issues with the
137. 5:09software. I'll leave it in English for
138. 5:11now; you can change it to Spanish later
139. 5:14if you want, but I prefer not to have
140. 5:16issues, so I'll leave it there. Now, to
141. 5:18make it look very similar to what you
142. 5:20see on screen, I'm going to select only
143. 5:23this module so everything else I have
144. 5:25installed doesn't appear, and I'll
145. 5:28press Start, which will launch
146. 5:30everything—the software is installed,
147. 5:32configured, perfect, and ready to use.
148. 5:35I don't have to do anything else. It's
149. 5:37already working. And look, the Blender
150. 5:39window has appeared with everything
151. 5:41configured to make things a little
152. 5:43easier for you. I'm going to make the
153. 5:45text a bit bigger here so you can see
154. 5:48everything I'm doing clearly on your
155. 5:50screen. I'll set it to 1.3. I think
156. 5:53that looks decent, and that way you can
157. 5:55follow the tutorial easily. And I'll
158. 5:57start this example directly by loading
159. 5:58a dental model, which is super easy. I
160. 6:00just find the folder and select the
161. 6:03models I want, drag them, and drop them
162. 6:05here, and it asks, "Are you importing
163. 6:07these two files?" Import. And that's it
164. 6:10, it's that simple, they appear in the
165. 6:12scene. It's nothing mystical, it's very
166. 6:14easy and I only have to make two clicks
167. 6:17. Now, these models are in PLY format.
168. 6:20If you don't know anything about these
169. 6:22formats, I'll leave this video here
170. 6:23where I explain it. But basically, they
171. 6:25are models with color. If I want to see
172. 6:28them with color, I go here where it
173. 6:30says "attribute" and we can see them
174. 6:32this way. Very nice, everything looks
175. 6:33great. Now, how are we going to
176. 6:35navigate this three-dimensional space
177. 6:38called the Blender scene? You need a
178. 6:40mouse, a mouse like that one there, not
179. 6:43the laptop trackpad—that won't work,
180. 6:45a mouse. Okay. If you don't have one,
181. 6:47go buy one for a few bucks and continue
182. 6:49with the tutorial. Okay. Now, with the
183. 6:52middle click, the button that has the
184. 6:54wheel, right? This button here, you
185. 6:56press it and you can do this, rotate
186. 6:59the camera around the model. This is
187. 7:01called orbiting. Yes. If I also combine
188. 7:05this with the Shift key, Shift and that
189. 7:07button, I can do this which is called
190. 7:10panning, that is, moving horizontally
191. 7:13or vertically. Finally, as you saw a
192. 7:16moment ago, if I roll that wheel
193. 7:18forward, I zoom in; backward, I zoom
194. 7:20out. Well, to make things easier,
195. 7:22I’ve added information here about
196. 7:24what I’m doing and pressing so you
197. 7:26can see it on screen. And here is an
198. 7:29important tip: when I start moving
199. 7:31things around, sometimes I want to
200. 7:33center the screen and see it from the
201. 7:36front, side, top, bottom, or whatever.
202. 7:38For that, I have these tools here,
203. 7:40which are the same as what I’ve
204. 7:42already explained. If I press this one
205. 7:44and view it from the Y axis, I am
206. 7:46looking at the object from the front. I
207. 7:49can also use the number pad on my
208. 7:52keyboard, the numbers on the right side
209. 7:54that look like a calculator. The one
210. 7:57key on the number pad shows me the
211. 8:00front, three is right, seven is top,
212. 8:03and the combination of Control 1, 3,
213. 8:06and 7 shows the opposite: back, left,
214. 8:09and bottom. As I showed, this is the
215. 8:12same as pressing these buttons. So, if
216. 8:15you don't have a number pad, this is a
217. 8:17viable option. Finally, if you don’t
218. 8:20have a mouse and choose not to listen
219. 8:22to me, you can use this one, clicking
220. 8:24and dragging to zoom. Click and move
221. 8:28this one to pan, and this one to orbit.
222. 8:32In other words, they are an alternative
223. 8:35way to navigate. Okay, I’ll view it
224. 8:37from the front by pressing Numpad 1,
225. 8:39and what I’m going to do is align
226. 8:41these models. I want these models to be
227. 8:43centered here in the middle so I can
228. 8:45work properly. This is a step you
229. 8:47shouldn't skip, and it's very easy to
230. 8:49do. I’m going to select the top model
231. 8:51. I’m going to press here. I’ll go
232. 8:54to this section. Notice that it has
233. 8:55different sections in the menu called "
234. 8:57models." If for any reason you are in
235. 9:00another menu, go back to "models," and
236. 9:03to collapse the menus—I press Control
237. 9:06and click to collapse them and leave
238. 9:09only the one I’m working on. So, "
239. 9:12model align center," I select the model
240. 9:15, notice it turns orange. And now I
241. 9:17press the first button. You always read
242. 9:19all the menus from top to bottom and
243. 9:21from left to right. So, to align in the
244. 9:23alignment section, I press the first
245. 9:25button, "enter target." To the bottom
246. 9:28model, this changes its name, right? It
247. 9:29tells you it's now called "target." We
248. 9:31call the model underneath "opposing." I
249. 9:33press "name opposing" and its name is
250. 9:36changed. And finally, I press the third
251. 9:38button, link flip, which shows me the
252. 9:41model face up, since when you imported
253. 9:43the models, they were sideways, facing
254. 9:45any which way. It's no problem. If you
255. 9:47follow these steps, they will align
256. 9:49properly. Now I'm going to place four
257. 9:51points. The next part says four points.
258. 9:53Place four points. There's even a hint
259. 9:56down here, a little note, a reminder,
260. 9:59an aid of what it is I need to do. It
261. 10:02says, "Press P to place the four points
262. 10:05in a rectangular shape." How do I do
263. 10:08this? Use the Shift key and the right
264. 10:11mouse click to move this circle, which
265. 10:14is called the cursor. I'll place it, in
266. 10:18my case, on two molar cusps. I can
267. 10:21press the P key, as it says here, or
268. 10:23this button so that the little dot
269. 10:25appears right here. If you don't have
270. 10:28it in color, by the way, I'll set it
271. 10:30here to texture, which is how it
272. 10:31usually looks. This little dot is red.
273. 10:34Okay, I'll continue like this for now.
274. 10:37I'll go over here. Shift, right-click,
275. 10:39and press P. Shift and right-click,
276. 10:42press P. Shift and right-click, press
277. 10:45P. This model is missing two laterals.
278. 10:48Poor patient. But well, it is what it
279. 10:50is. Once it's like this, I'll press the
280. 10:53align button and boom. Everything
281. 10:56aligns in a second. Perfect. Sure, it
282. 10:58ended up upside down, but it doesn't
283. 11:00matter because it's already centered.
284. 11:02Now I have these three tools to rotate
285. 11:04it. 180 degrees, or if I had to flip it
286. 11:07on the Z-axis, I could do that. It has
287. 11:10a note here that says X, Y, Z. The
288. 11:13X-axis, by the way, is this horizontal
289. 11:16line. If I use X, it will rotate this
290. 11:18way, right? On this line. The Y-axis is
291. 11:21this vertical line; it will rotate on
292. 11:23this line. And the Z-axis, which you
293. 11:25can't see right now, but I can show it
294. 11:27here, is this blue line. So it would
295. 11:29rotate in this direction. Since what I
296. 11:32need is to rotate it like this on the
297. 11:34Y-axis, I use Y. And now it's facing
298. 11:37front. Two clicks here and it's done.
299. 11:40So now it is perfectly aligned and I
300. 11:42can start working. The first thing will
301. 11:45be to cut all those excesses because
302. 11:47the scanner doesn't do it perfectly,
303. 11:49and I'll do it super easily. I like to
304. 11:51hide the model I'm not working on and
305. 11:54show the one I am working on. To hide,
306. 11:57I press, select the model, and press
307. 11:59the H key. When I want to show them
308. 12:02again, Alt + H, it's that easy. I have
309. 12:04the same thing up here too. If I go
310. 12:07here, I can select and press the hide
311. 12:09button, and it says H here, or unhide,
312. 12:12Alt, it's the same. Okay. I really like
313. 12:15shortcuts, so I use the H key. Let's
314. 12:17move on to the next section. Cut and
315. 12:20patch, which would be trimming the
316. 12:22model. For that, again, I will use my
317. 12:24cursor, keeping in mind that the object
318. 12:27is selected and has an orange outline.
319. 12:29All good. Shift and right-click to
320. 12:31place the cursor where I want to start.
321. 12:33And I'm going to make a little drawing,
322. 12:35Archcut. And this is basically going to
323. 12:38be the cut line. With the G key, as you
324. 12:41see on screen, I can move this point,
325. 12:43and with the E key, I can add an extra
326. 12:46point. I will make relatively short
327. 12:49points and I will go along drawing the
328. 12:51contour where I want to clean this
329. 12:54model. Everything that is irregular
330. 12:56will go away and everything below the
331. 12:59line will look very good. Okay, I'll
332. 13:01continue. If I find things like this, I
333. 13:04don't make big steps, but rather small
334. 13:06steps so that it follows the shape
335. 13:08correctly. I will keep moving forward
336. 13:10here on these details that are not flat
337. 13:12, they are not flat surfaces, but
338. 13:14irregular ones, so I make more little
339. 13:16points. Yes. And if I want to correct
340. 13:18any, for example, this one here, I
341. 13:20select it and with the G key I correct
342. 13:22it. Okay, this one too, or whatever.
343. 13:25I'm going to go around the entire model
344. 13:27and in this case, I'm going to leave
345. 13:29the palate. So I'm going to move along
346. 13:31this area. I am pressing E every time
347. 13:35to create a new vertex. And when I
348. 13:38reach the other end, I go here and
349. 13:40press the fuse option so they connect.
350. 13:43Okay, just like that, so easy. I have
351. 13:46drawn everything I want to delete and
352. 13:49now I press trim. Trim cuts the bad
353. 13:51part and leaves the good part, but
354. 13:53since it doesn't know which is the good
355. 13:55one and which is the bad one, it will
356. 13:57ask me to decide which one I want to
357. 14:00keep. So I select a vertex or an area
358. 14:02of the good part, I clicked here, and
359. 14:05then I press clean and this deletes
360. 14:07everything bad, leaves the good, and
361. 14:09that's it. Now this model, as you will
362. 14:12see, now that it's cleaned, has a very
363. 14:15good contour. Now yes, very clean, very
364. 14:18regular, as it should be, but it's
365. 14:20still not ready to be printed. So, in
366. 14:23order to print this model, I need to
367. 14:25make it watertight. In the 3D world,
368. 14:27it’s called manifold, and it’s very
369. 14:29easy to do. I go down here to the base
370. 14:32option, and since this is the upper
371. 14:34model, I press oper base. That will
372. 14:37close the model and get it ready for
373. 14:40printing. Here, if I wanted, I could
374. 14:42hollow the model, or I could just
375. 14:44export it and take it to print. I
376. 14:46hollow the model during the export
377. 14:49phase, but I could do it in Blender for
378. 14:52Dental, but to keep this tutorial
379. 14:55concise, I won't. And if you want to
380. 14:57learn how I do it with Chitubox, I’ll
381. 14:58leave this video right here. But
382. 15:00basically, with that, this model is
383. 15:02ready. If I want the base to be bigger
384. 15:04or smaller, I have some arrows here to
385. 15:06modify it, but in this case, since I
386. 15:08want the palate, I’ll leave it as is.
387. 15:11Okay, let’s move on to the lower
388. 15:13model, and I’ll show you a second
389. 15:15alternative, which is the one I use
390. 15:18most frequently to show it again, right
391. 15:20? Alt + H, and now I’m going to hide
392. 15:23the upper one. Right, what do I do?
393. 15:25Most of the time to clean the model,
394. 15:28instead of drawing that line, which is
395. 15:31fine, but I like to do it faster, I’m
396. 15:34going to go into a special mode inside
397. 15:38Blender called edit mode. I can do it
398. 15:40from here with Fast Edit or with the
399. 15:43Tab key. This time I’ll press the
400. 15:45button because it takes me to this
401. 15:48specific mode where I’m using
402. 15:50something called X-ray mode. If you
403. 15:53notice, I can see the back of the model
404. 15:55, and also in that edit mode, as it
405. 15:58says up here, Edit Mode, in case you
406. 16:00need to change it. Here is where I can
407. 16:03turn off or deactivate that X-ray mode.
408. 16:05If I deactivate it, I only see the
409. 16:07front. If I activate it, I see the
410. 16:09front and the back. Why do I want X-ray
411. 16:11mode active? Because it allows me to
412. 16:14select all the vertices or faces that I
413. 16:16want to remove. Right now, I’m going
414. 16:19to press the C key on my keyboard to
415. 16:21make this circle, and I’m going to
416. 16:23paint over all that edge I don’t like
417. 16:25. I’ll paint it quickly like this.
418. 16:28I’ll rotate over here. By the way,
419. 16:30when the C key is active, I can’t pan
420. 16:32, I can’t rotate, I can’t do
421. 16:33anything. So, I right-click to cancel
422. 16:37the tool. And now I can rotate. Yes, I
423. 16:39have to be careful because if I look at
424. 16:42it from here, for example, and I press
425. 16:44C, what happens? That I'm selecting
426. 16:45this part here, but also what's behind
427. 16:47it. Control Z to deactivate or undo it.
428. 16:51And I'm going to tilt the model down a
429. 16:54little to quickly select just that edge
430. 16:57. Yes, I'm going to turn this this way.
431. 16:59I'm going to continue with this here.
432. 17:01The whole edge and everything I want to
433. 17:03remove, I do by painting. It's that
434. 17:05easy. Yes. Once I reach the other side,
435. 17:09I repeat exactly the same process. I'll
436. 17:12do it a bit faster now. And with that,
437. 17:16I have everything I don't want selected
438. 17:20. Here on the inside part, too. I'll do
439. 17:22it super fast like this. Done. And
440. 17:26there it is. Very good. Okay. Now the
441. 17:29same as before, but deleting. Since
442. 17:32I've already selected everything I
443. 17:34don't want, I'll press the delete
444. 17:36button. All of that goes away. The edge
445. 17:38is regular enough for it to work. I
446. 17:42have a little detail left here. Look,
447. 17:44something interesting here to clean it
448. 17:46up. If I wanted to, I could press the
449. 17:49Tab key to go to edit mode. I select
450. 17:52something from the area I want to keep
451. 17:54and press clean. And this little piece
452. 17:56goes away. Okay. Tab to return to
453. 17:59object mode. This is object mode. This
454. 18:01is edit mode. Okay, in object mode I
455. 18:03move the entire object. In edit mode I
456. 18:05access the vertices, faces, and edges.
457. 18:08Okay, I go back down to the bases,
458. 18:10press lower base, and just like before,
459. 18:12in a few seconds, I have a model ready,
460. 18:15clean and ready to print. Now, if you
461. 18:17have trouble doing this, it could be
462. 18:19one of two things. One, it could be
463. 18:22that you have a hole in the model. I'll
464. 18:26do it as an example. Here, I'm going to
465. 18:28make a hole here. Bam, bam, bam. And if
466. 18:30you have this hole and you create the
467. 18:32base, it's going to create a mini base
468. 18:34in that hole and that's a problem. So,
469. 18:36an extra tip, well, it did it right
470. 18:37this time, but it doesn't always do it
471. 18:39perfectly. I can't even make mistakes,
472. 18:41what's up with that? But if it's giving
473. 18:43you that problem, in this option down
474. 18:46here that says cut fill and patch, or
475. 18:48up here, sorry, you can close those
476. 18:51holes, I press fill holes and that will
477. 18:53fill that up nicely. And now, when I
478. 18:55create the base, that base will be
479. 18:57created properly, although it did it
480. 18:59right before, so what can I tell you? I
481. 19:01don't know. In any case, I have both
482. 19:03models ready at the H-max, and I could
483. 19:05already send this to export, but I want
484. 19:08to give you an extra. So subscribe,
485. 19:10because I'm showing you the secrets of
486. 19:13Blender for Dental—which aren't
487. 19:15really secrets at all—but if I want
488. 19:18this to hold, if I want this occlusion
489. 19:20to stay when printing the models, I can
490. 19:23add simple little occluders here. So we
491. 19:26are going to do that as a final step,
492. 19:28and I'll go to this option that says
493. 19:30articulation, and I'll look with the
494. 19:33cursor where I want to place them. I'm
495. 19:35going to put three. I could put four if
496. 19:37I wanted to, but I'll put three. I'll
497. 19:39put one here. I press the one that says
498. 19:41articulator, and actually, it didn't
499. 19:42listen to me. It went to the middle.
500. 19:44With the arrow, I pull it, I pull it,
501. 19:46and look, it appears in the middle.
502. 19:48That's why it's so important that this
503. 19:50is aligned. Yes, I'll look at it from
504. 19:52above with the seven key, and I'll
505. 19:55bring it with G until it touches the
506. 19:57model. I can rotate it with R, and I'll
507. 19:59do it like this, right? Good. I'll do
508. 20:02the same on the other side, but to
509. 20:04avoid pressing articulator, I press
510. 20:06copy and it gives me an identical one.
511. 20:08Rotate and I place it around here. Yes.
512. 20:11And one more, I'll press G and R to
513. 20:13rotate and place it in the front. Yes.
514. 20:16If you want to put four to have them on
515. 20:17the sides, well, you just put them,
516. 20:19right? It's nothing scientific. This is
517. 20:22very easy. Now, here is one thing: the
518. 20:24models on the top, or the articulators
519. 20:27on the top, are looking fine, but on
520. 20:30the bottom they are sticking out a bit,
521. 20:33right? So, what could I do? Very
522. 20:35important, do not separate these two
523. 20:38pieces. Yes, they are two individual
524. 20:39pieces. If you separate them, they will
525. 20:41never match up again. I select both
526. 20:43pieces, shift, click. They were already
527. 20:47selected before, but this way I select
528. 20:49both, and with the arrow, I move it so
529. 20:50it stays above the bottom edge, because
530. 20:52I'm going to set this like this. And
531. 20:54now, to connect this here, I'll use
532. 20:57this little arrow, and that arrow
533. 20:59extends it forward. Ready. I'll do the
534. 21:02same with the other two. I can also
535. 21:04show this menu here with the T key and
536. 21:08choose the box option from this list.
537. 21:11Yes, with the box option, I can select
538. 21:13it like this. And now G to move. And if
539. 21:17I want to move it only vertically, here
540. 21:19is another interesting tip. I press the
541. 21:22axis I want to move on, for example, G
542. 21:24and Z. And that way I move it only
543. 21:26vertically. I'll raise it a little bit
544. 21:28there so it stays above that edge.
545. 21:30Nothing happens here. If it sticks out
546. 21:31or whatever. And that's it. I'll leave
547. 21:34it just right. And here the same, GZ to
548. 21:37raise it. Now, if you don't like it, if
549. 21:39it bothers you that it's like this, if
550. 21:41you want it to be perfect and blah blah
551. 21:44blah, well, no problem, my dear friend,
552. 21:46because this is very easy to fix. What
553. 21:48I'm going to do is box-select the three
554. 21:50of them. Yes, I'm going to press the S
555. 21:53and Z keys, as we said before, S and Z.
556. 21:56And this scales vertically. Like this.
557. 21:59Very good. Now to move it down a little
558. 22:02bit. And look, now it turned out
559. 22:05fantastic. Okay, this is perfect. And
560. 22:08now I'm going to export. How do I
561. 22:10export the files? I want this part at
562. 22:13the top to be one object and this part
563. 22:14at the bottom one object. So I have to
564. 22:17combine everything. How do I do that?
565. 22:19Very easy. I make this box, I select
566. 22:22one of them because I want it to be the
567. 22:25active object. This is another Blender
568. 22:27concept. The active object is the most
569. 22:29important object. So, I press the Shift
570. 22:32key and click, for example, on the
571. 22:33model. And notice it's lighter. That is
572. 22:36the active object. Here I can combine
573. 22:38them with the key combination Control
574. 22:41and J, or in this initial menu I press
575. 22:44join objects and the three of them
576. 22:46combine. Same thing down here. I select
577. 22:48everything. Shift and click to select
578. 22:51the model. This time Control J, exactly
579. 22:54the same thing happened. I have one
580. 22:56file at the top, one file at the bottom
581. 22:58. I can export them one by one, but I
582. 23:00prefer to export them all at once. I
583. 23:02select everything. I go here to File,
584. 23:05Export, STL. I'm going to make a folder
585. 23:08here called export. Yes. And I'm going
586. 23:11to select two things. One, the button
587. 23:13that says Selection Only, because if I
588. 23:16have other things around in the scene,
589. 23:18it won't export those. And then the
590. 23:20batch option so that each object is
591. 23:22exported individually, because if I
592. 23:24don't select it, those two models will
593. 23:26combine too. So these two remain
594. 23:28selected, the name, I give it the name
595. 23:31I want, for example, models, and export
596. 23:34. And with that, if I go to this export
597. 23:37folder, there's the top model, exactly
598. 23:40as I defined it and with its parts on
599. 23:43the sides, and of course the bottom
600. 23:45model too. That's it. With that, you
601. 23:48have models ready to print in seconds,
602. 23:50perfect to send straight to the slicer,
603. 23:53and you have basically started your
604. 23:55journey in the world of Blender for
605. 23:57Dental. If you liked the tutorial and
