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!
I'm also delighted you are back!
i love your videos!
Same :)
Not anymore... :(

*_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.
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.
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 ;)
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
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.
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...
Holy crap those things are cooler than I thought.
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.
it's nice to see Mark Hamill making engineer videos again now that he's done filming episode 8
We missed you, Bill! I can't count how many times I rewatch your videos, and I'm excited for your book!
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.
Great to have new engineerguy videos. Very informative and high quality as always.
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.
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.
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!
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!!!
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!
This is probably the most detailed and most informative video I've seen about DLP 3D printers. Great to have you back Bill!
I could listen to Bill talk all day, every day
The research and production quality that goes into these videos is insane. Great pacing yet also packed with information.
I love the opening when he just fades in behind the title. Like he just phases into existence to tell us about engineering but is not a part of our reality the rest of the time.
Really enjoyed this video. Thank you.
Glad you came back! Missed the great videos, no fuss or full of special effects, pure and great engineering
Welcome back Bill, glad to see your videos again!
Happy to see you back! Here's to many more engineer guy episodes.
Nice to see you back on the tubes, Bill. Your insight into every day marvels has been missed.
So glad you are back Bill!

Nice!
I don't know how more people don't watch this channel. I find myself constantly fascinated with your videos!
I missed you a lot Bill ! Thanks for coming back, looking forward to seeing what's next (:
Wow, when you come back, you come back with a bang! Awesome video!
I'm always excited to see a new engineerguy episode. Great job Bill.
We missed you, welcome back!
he gone
Still one of my favourite channels - such fascinating and understated topics
These should be the kind of video that should millions of views. Great video
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!
Glad you're back!
Wow, how I missed this channel, the level of quality and depth is awesome.
Good to see you again, Bill.
Right into the video, no nonsense. You really deliver great videos. Glad to see you are back.
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.
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!
So glad to see you're back! Fascinating as always
Excellent video. Welcome back Bill. Missed you.
It's great to see you again
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!
Yay. So good to see you back!
Holy damn, every one of those is worth the wait. Keep up the great work.
Soooo happy that you are back!
This is the best channel ever and you are an amazing science communicator
I love my FDM printer, but this stereolithography technology is ridiculously amazing!
Back with a bang. Good stuff.
The resolution of that is insane. Another great production. Thanks!
I’ve got a elegelu Mars, I already know resin 3-D printing pretty well but I watch this video because I like the way you explain the cans😅
This is really fascinating and I'm delighted you're back!
Wow, you describe this with such beautiful simplicity.
Just as elegant as always, I'm glad 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.
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.
So glad he's back.
Thank god you're back bill.
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.
This is absolutely fascinating technology! And presented flawlessly as always, Bill.
Thanks Bill! Another great video. Glad to see you back!
Good to see you back!
Engineer Guy IS BACK!!!
Be welcome again, and thank you for the quality content.
At last! He's back! Welcome Bill!
You are a shining beacon of high quality content.
His explanation is so very calming..
Thank you!!! We need more people like you in this world!!
Glad to see a new post!
Oh I really missed your amazing videos! Thank you for coming back!
Great video! Thorough, and full of information, yet concise.
Glad this channel isn't dead
Definitely missed these videos
I have intimate knowledge of the process, as I work with SLA/DLP printers, but I still took a great pleasure in watching this video.
Thank god for people like Bill
So happy to see you post a video, your content is of the highest quality. Please keep up the good work.
Amazing. I learned more about 3d printing in 12 mins than I ever thought I would. Thanks and keep up with the good work
Welcome back! We missed your videos.
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.
Great video as always, congratulations on being a father, amazed that you still find time to do so much while being a parent
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.
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
Superb. This guy needs a TV program on discovery or sci channel. What a wonderfully described process of applied science.
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
One of the best places to get knowledge about tech!
Missed your videos sir. So glad to see you are back!
Welcome back, engineerguy
I have the biggest engineering crush on you. Your works are legendary. Thanks you kindly for these videos :)
Hey professor, I'm glad you're back.
Honestly i was wondering this. Thank you very much. Love all you videos.
This thing will be a collector’s item, for sure
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!!!
Amazing explanation of a complex machine to actually make it sound understandable - superb stuff!
