I'm also delighted you are back!
i love your videos!
Same :)
Not anymore... :(
@@leozendo3500 why?
he gone
So glad this channel is not dead. I know we shouldn't expect regular videos but just knowing you are still active is good. All the best with your child
+Kobi Jenkins thank you. I am enjoying fatherhood a great deal.
Thank god, I thought that something bad happened to his child :/
these videos are amazing thanks so much!! complex amazing things explained so easy!
engineerguy- You look like Andrew Carlssin, a real self proclaimed time traveler who was interrogated by the FBI in 2003 after he had an impossibly perfect run of good luck with stock exchange that helped him turn $800 into hundreds of millions of dollars in a large streak of highly suspicious investments. The story goes that, Andrew Clarlssin confessed to the FBI in a 4 hour long interrogation that he was from about 240 years in the future and something about wanting to start a company in 2007. In exchange for his release he offered to reveal a cure for AIDS and the location of Osama bin laden who, in 2003 was still in hiding. Andrew Carlssin was arrested but a mysterious stranger paid his $1 million bail and he hasn't really been heard from since except supposedly in a phone call made years later
Belated congratulations!
*_The difference between an engineerguy video and a Vsauce video is, you won't have an existential crises after an engineerguy video._*
This is so very true.
@@chrisedwards3866 ⚠️ God has said in the Quran:
🔵 { O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 )
🔴 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 )
🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 )
🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 )
🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 )

Also Bill is not annoying.
Welcome back! Fascinating video. Glad you mentioned the benchy. That boat has given me a lot of trouble in my forays into 3d printing ;)
Oh hey :D
Fancy seeing you here ^^
I'm glad you are back
I was about to write this exact comment till I saw yours
Same here, damn good to have you back.
I'm a little bit interested in understanding how those micromirrors are constructed in the first place
The hinges are probably done in a similar fashion as transistors (I think there is an engineerguy video about that) but I have no idea how the aluminium is attached
Lempika Ben Krasnow from Applied Science did an excellent video about DLP a few years ago. Check out his channel
I think it is most likely the same production process used for CPU chips, EUV-lithography.
Check out machines like ASML Twinscan NXE.
See his video on phone accelerometer etching
No real knowledge, but I would hazard to quess that the mirror is actually attached as a single plate on top of the "forest" of posts. Then it is cut to pieces (probably with something like laser or stereolithography etching). Thus removing the need to place millions of tiny mirrors. Rather you place one big mirror layer and then section it.
I often get questions about DLP printers and I shall definitely share this excellent video. I'm very happy that my swan proved useful in your demonstration.
How wonderful to see you show up here: I like that little swan!
engineerguy is the first company you spoke about Arconic? They print aerospace parts. I just spent my summer interning there as a process engineer r
It’s crazy how far resin printers have come since this video was made. Resin printers have gone through the same transformation as flat panel TVs, becoming bigger, better, way cheaper, and way more common over the years.
engineerguy is back with more content! Woop woop!
Could you do an episode about concrete? Not just the modern version but other forms that are used and have been used, perhaps.
+lazygamerz I have been thinking of that: I find it fascinating.
I used to work in a lab where we experimented with "monomolecular" concrete that used flyash and a chemical bonding agent. It was incredibly strong (8 times the compressive strength of regular concrete) and it was heat/acid proof.... however its main drawback was its viscosity... it couldnt be poured and was quick to cure.
Concrete would be fascinating; there's probably enough content on the subject for an entire series. I'd love to hear your explanation of the way different compositions have different trade-offs. Or some explanation of the recent attempts to make lighter-weight concrete, and more environmentally-friendly compositions, would be great too, as concrete is major source of CO2 emissions.
Material science is always amazing.
Holy crap those things are cooler than I thought.
Feels good to have you back as the understanding sinks in. You are the best whether it is today, tomorrow, or next year...see ya then.
Hey Bill, nobody could have explained the DLP & SLA technologies as crisp and fast as you have. In just 12 minutes you have empowered me with the knowledge that many in the trade would not even have. A big thanks to you... Keep up the good work...
Great to have new engineerguy videos. Very informative and high quality as always.
It's so good to have you back Bill. Thanks for taking the time out of your busy life to explain these things to the world.
We missed you, Bill! I can't count how many times I rewatch your videos, and I'm excited for your book!
Thank you, Bill. Your channel is always so thoughtful, thorough, and informative. It's a great service to all who wonder how and why things work the way they do!
The research and production quality that goes into these videos is insane. Great pacing yet also packed with information.
I remember watching this back when it came out thinking wow this is so high tech and futuristic. Now I have a Elegoo Saturn 3d printer.
so many good youtubers leave never to be seen again. you were among the great martyrs. and now youre back. i cant believe it! i love this!!!
This is probably the most detailed and most informative video I've seen about DLP 3D printers. Great to have you back Bill!
Glad you came back! Missed the great videos, no fuss or full of special effects, pure and great engineering
I'm always excited to see a new engineerguy episode. Great job Bill.
I hate when people say your dead these videos take a long time to make and I appreciate the work put into it thanks for these good videos ;)
Welcome back Bill, glad to see your videos again!
Nice to see you back on the tubes, Bill. Your insight into every day marvels has been missed.
I don't know how more people don't watch this channel. I find myself constantly fascinated with your videos!
Welcome back Bill! Really missed your videos. I recently got an FDM printer, and it's so much fun printing stuff out. Thanks for the video!
Really enjoyed this video. Thank you.
I wrote patent applications on 3D printing of gas turbine engine blades and blisks. Wish I had seen your video about five years ago. Your explanation is so well articulated, my gaad you are amazing! Thanks!
Wow, how I missed this channel, the level of quality and depth is awesome.
This is absolutely fascinating technology! And presented flawlessly as always, Bill.
I missed you a lot Bill ! Thanks for coming back, looking forward to seeing what's next (:
So glad you are back Bill!
Thank you even though I had a decent crude idea of how they worked and some of the mechanics involved seeing it this way and how you broke it down really put it all into perspective. Much appreciated
Holy damn, every one of those is worth the wait. Keep up the great work.
Great video Bill! I can tell you really put the effort into these to explain them well. The animations, highlighting, and editing are fantastic as well.
Right into the video, no nonsense. You really deliver great videos. Glad to see you are back.
Happy to see you back! Here's to many more engineer guy episodes.
Wow, you describe this with such beautiful simplicity.
Still one of my favourite channels - such fascinating and understated topics
Your videos are fascinating. It's like you know exactly what question I want to ask, and then you answer it right then and there. Absolutely fantastic content.
Very happy to see you are still creating videos! You make such high quality videos that I'm always very eager to watch the next one. Thanks!
I could listen to Bill talk all day, every day
The resolution of that is insane. Another great production. Thanks!
This is the best channel ever and you are an amazing science communicator
So glad to see you're back! Fascinating as always
This is the most explanatory video on the subject I have ever seen.. Thank you very much for the extreme effort that went into making this video! Keep up the good work! This is very high quality content!!!
Engineer Guy IS BACK!!!
Be welcome again, and thank you for the quality content.
I was going to link the applied science bid on DLP, but I see Bill already did. Thank you for your work my family and I enjoy every video you make!
This is really fascinating and I'm delighted you're back!
I know how FFF printers work and have built them myself, but had no idea about DLP. The level of detail you went into in this video was fantastic. It's great to hear from you again, best wishes to you and your family.
I find this channel absolutely fascinating. Thank you for the time you spend to accurately explain the workings of different objects that even us nitwits can understand.
Amazing. I learned more about 3d printing in 12 mins than I ever thought I would. Thanks and keep up with the good work
Missed your videos sir. So glad to see you are back!
Always wonderful to see such well thought out content.
Both informational and entertaining.
Oh I really missed your amazing videos! Thank you for coming back!
Thanks Bill! Another great video. Glad to see you back!
Wow, when you come back, you come back with a bang! Awesome video!
Amazing explanation of a complex machine to actually make it sound understandable - superb stuff!
Wow !! This was greater than discovery channel! Greeting from Mexico! Your videos are incredible! You save years ago with you "why cans are made like this" video . Thank you so much
His explanation is so very calming..
Just as elegant as always, I'm glad you're back.
You are really great at explaining things in super understandable way!
So glad you're back! This was a great video topic, absolutely fascinating.
So happy to see you post a video, your content is of the highest quality. Please keep up the good work.
Excellent video. Welcome back Bill. Missed you.
Great video as always, congratulations on being a father, amazed that you still find time to do so much while being a parent
What an extremely well written descriptive video. Kept to the point of the technology behind 3d printing while elaborating on key elements. Thanks.
Definitely missed these videos
First, congrats on having that youngster! We were "late life" parents and it worked out great. Next, thanks for your videos as they are excellent. We'll chase down your book about the airship.
Incredible engineering. Thanks for explaining it so well!
Welcome back! Looking forward to more :> can never have enough engineer guy. Thanks bill and team
It's great to see you again
Great video! I already understood.most of how this type of printer worked, but it was great to see it explained in great detail in terms that laymen could understand!
You're back :D I'm really glad. I discovered your channel in the middle of your sabbatical and was crushed when I thought you had abandoned the channel.
You are a shining beacon of high quality content.
Great video! Thorough, and full of information, yet concise.
Just started binging this channel (again) a few days ago and I'm glad I did else I probably would have missed these new uploads.
One of the best places to get knowledge about tech!
These should be the kind of video that should millions of views. Great video
Good to see you again, Bill.
Welcome back! We missed your videos.
Glad you're back!
I was very impressed with my first DLP but I didn't realize that I had TI to think for that technology, so my thanks go to you now that I know where my appreciation is due. 👍👍
And now you have me very intrigued as to the chemistry and how this resin functions...
You are very good at what you do. I don't know of any teacher, tv host, CZcams channel, or person that has ever explained things as well as you do. Your graphics are perfectly done in a way to convey the ideas you are presenting. I'm just some guy on the Internet, but you should be paid by Science Channel to have your own show. No joke.
Thank you!!! We need more people like you in this world!!
I very much enjoy your videos. They are extremely well written! Glad to have you back
Good to see you again, nice subject and as always lovely method of explanation!!
Honestly i was wondering this. Thank you very much. Love all you videos.
That was really interesting thanks so much and very glad to see you back! I really missed your videos.
So glad I found this channel. Easy to understand, entertaining to watch. Thanks a lot for your great work :)
absolutely fantastic video; super super super happy to see more from you!
Your video after such a long time is still very nice. You have done your job so well that I can get all the informations that is important about this type of 3D printing technique! Thanks a lot sir!
Glad to see you're back. Great video 👍 keep up the good work.
This is the 1st video since I subscribed a while ago...
Glad you are masking them again...
This channel is my favorite, best teacher i ever saw!!
Wow Bill. That was very well done. Thank you for the video!
it's nice to see Mark Hamill making engineer videos again now that he's done filming episode 8
This is truely fascinating! Thanks Bill.
Very interesting. SLD printing immediately conjures the question of how to limit the amount of resin being cured. This is one answer I did not expect, which is why the tray moving had me surprised, but it makes perfect sense with your explanation.
