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... :(
@@leozendo3500 why?
he gone
*_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.
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.
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 ^^
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.
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 don't know how more people don't watch this channel. I find myself constantly fascinated with your videos!
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'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.
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...
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 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.
it's nice to see Mark Hamill making engineer videos again now that he's done filming episode 8
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.
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.
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.
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.
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.
This is probably the most detailed and most informative video I've seen about DLP 3D printers. Great to have you back Bill!
Great to have new engineerguy videos. Very informative and high quality as always.
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!!!
Holy crap those things are cooler than I thought.
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!
Glad you came back! Missed the great videos, no fuss or full of special effects, pure and great engineering
His explanation is so very calming..
I could listen to Bill talk all day, every day
Wow, how I missed this channel, the level of quality and depth is awesome.
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.
Nice to see you back on the tubes, Bill. Your insight into every day marvels has been missed.
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
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!
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.
Right into the video, no nonsense. You really deliver great videos. Glad to see you are back.
Welcome back Bill, glad to see your videos again!
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.
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!
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.
Happy to see you back! Here's to many more engineer guy episodes.
I'm always excited to see a new engineerguy episode. Great job Bill.
So glad you are back Bill!
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.
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!
Wow, you describe this with such beautiful simplicity.
So glad to see you're back! Fascinating as always
I missed you a lot Bill ! Thanks for coming back, looking forward to seeing what's next (:
Great video as always, congratulations on being a father, amazed that you still find time to do so much while being a parent
The resolution of that is insane. Another great production. Thanks!
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!!!
> The printer featured is an Ember printer, manufactured originally by Autodesk, but now an open source project.
Nice!
I love my FDM printer, but this stereolithography technology is ridiculously amazing!
Superb. This guy needs a TV program on discovery or sci channel. What a wonderfully described process of applied science.
Wow Bill, you explained in simple manner. I wish i had mentor like you in my bachelors. Respect from India
This is the best channel ever and you are an amazing science communicator
Wow, when you come back, you come back with a bang! Awesome video!
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.
This thing will be a collector’s item, for sure
So happy to see you post a video, your content is of the highest quality. Please keep up the good work.
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
Engineer Guy IS BACK!!!
Be welcome again, and thank you for the quality content.
This is really fascinating and I'm delighted you're back!
Amazing. I learned more about 3d printing in 12 mins than I ever thought I would. Thanks and keep up with the good work
I must be dead and this is heaven. A new vid from the engineerguy.
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😅
Glad this channel isn't dead
Just as elegant as always, I'm glad you're back.
You are very good at what you do. I don't know of any teacher, tv host, TH-cam 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.
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.
Excellent video. Welcome back Bill. Missed you.
You are a shining beacon of high quality content.
Missed your videos sir. So glad to see you are back!
Sir pausing the video in middle to appreciate your work
You are really great at explaining things in super understandable way!
Amazing explanation of a complex machine to actually make it sound understandable - superb stuff!
Definitely missed these videos
This is absolutely fascinating technology! And presented flawlessly as always, Bill.
Good to see you again, Bill.
So glad you're back! This was a great video topic, absolutely fascinating.
One of the best places to get knowledge about tech!
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! Thorough, and full of information, yet concise.
Oh I really missed your amazing videos! Thank you for coming back!
This channel is my favorite, best teacher i ever saw!!
It's great to see you again
Glad you're back!
Bill is nothing but 100% class.
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
Soooo happy that you are back!
Yay. So good to see you back!
I was wondering about this channel lol. congrats on the new addition to the family.
Glad to see you're back. Great video 👍 keep up the good work.
Thanks Bill! Another great video. Glad to see you back!
Welcome back! We missed your videos.
your back and the content is better than ever, awesome video!!
Holy damn, every one of those is worth the wait. Keep up the great work.
Using this printer was a component of the final project for ME170 CAD class in 2001 at UIUC!
I have the biggest engineering crush on you. Your works are legendary. Thanks you kindly for these videos :)
