can't believe this, I was hoping for an upload for years , i enjoyed watching every single video in this channel thank you for your time and have a great day
Thank you Mr. Gelbart for an extremely informative video. So much of this stuff was just referred to in my materials class in college, but you made it much more understandable.
Thank you! Your videos are among the best on youTube for providing concise, informed advice and knowledge regarding basic prototyping and related processes. I realize it's a huge time investment. But your knowledge and experience provides insight that is often unavailable outside an academic or commercial environment.
Dan, I enjoyed watching your prototype series a lot and also learned a lot as I originally studied electrical engineering and work in the IT business for that last decades. I am glad you posted another video today. I hope more will follow soon.
YES!!! You have no idea how much I needed this, I’m hoping to get a job in a prototyping shop thats getting a 3D metal printer shortly. Love your videos, please don’t disappear again
Or reduce sag potential by about half by submerging parts in an ionic liquid inside a vacuum chamber. You would still need to vent off water vapour from the binder paste though.
Great discussion on when to use traditional processes ( CNC, investment cast, etc) vs Additive manufacturing like 3D metal. My takeaways: use 3D metal printing for with internal and/or external complexity, thin parts print faster, post-process machining is required and can be time-consuming, sintering has 16-20% shrinkage in volume, Support structures are needed to prevent warping during printing, annealing in an inert atmosphere to remove printing stresses, wire EDM is one method to remove supports, Cost is $1million for setup plus specialized facility to work in.
Cost of the laser systems (for the same build volume) is high, The sintering type system cost is about $170,000. No machining or post processing needed for sintering type systems in order to remove supports.
So surprising to see your face on the list on new videos ... what did I do wrong ... nothing it IS a new video from Dan Gelbart ! So nice to hear and see you again ... I just got myself a 3D printer mostly for making patterns for my foundry, but what a wonder machine - it can be used for making so many different things ... I didn't knew I missed it so much making fun stuff too ! Again, thx for your inspiring videos !
Good sir, thank you for your video. What I'm interested here is the strength of the materials after printed, compared to machined. Obviously, if the strength was comparable then printing might take over much more than if the strength of a machined part was higher.
That depends on the quality of the metal powder, i.e. is the powder spherical or not uniform. (As Stated in the video) Quality control is being developed for being able to determine material micro-structure during a print.
Thanks for sharing Dan. I'm a metallurgical engineer and have some experience with metal additive manufacturing (slm, fdm and binder jet). How much shrinkage does this process have? Is it compensated for in the slicer? I've done some microstructure comparisons between the methods I previously mentioned and all of the methods have some level of porosity, roughly 1-5%, how does your machine perform?
The porosity is 1-2% (i.e. the density is 98-99% of theoretical density. You cabn see full material properties and microstructure photos at www.rapidia.com/materials
Why did you not print a DIN/ISO Test Piece and Test the Tensile Strength and other properties on the Test piece? Instead you show a compression test, which is very deceiving, especially since you said there is no infill! Would be interesting to know if you have Layer Issues.
here's what i wonder. how does the observiverse download all of the information in this guys head, and distribute and communicate this unambiguously to each other in the most palatable and least-costly (in terms of mental time cost) way. or is this just another living example of heroic ledges that nobody will climb for another 500 years?
In the last four years I was busy leading a very talented team of people at Rapidia, developing this 3D metal printing technology. Before that I was in medical devices (Kardium), before that in regular printing (Creo) , even before that in Imaging , before that in Telecom (the list goes on).
I really appreciate the fact you included pricing for the printer, that kind of thing always seems to be a secret for most companies and it's difficult to get public figures.
Dan - I learn more from you in 45 minutes than I could from taking an entire 40-hour class. You have an amazing knack for distilling information down to the most critical and memorable elements, in an approachable way that someone who's merely curious about it with no experience can understand. I wish we could clone you and have access to your lifetime of lessons learned.
Check all other Dan's videos : you'll get 3 years of mechanical engineering M.Sc. level manufacturing courses in a handful of videos. Never so much used Pause button to take notes on a RUclips video ever ! ;-)
I thought I would jot down a short thank you note to tell you how much I have appreciated your videos. Very rarely do you find someone who can communicate complex information in such a digestible manner. Delightfully delivered with an authority that leaves the viewer in no doubt we are listening to a master in their field. These videos are in a class of their own and I keep them in a special library. As a kid in the 1970s in the UK we had a BBC science journalist called James Burke and he was a very special communicator. I get the same excitement and connection with the subject material that I did all those years ago. Thank you very much Dan.
I was going to say the same thing -- this was a very clear explanation, and very soothing in style! There is definitely something great in the old BBC series -- and there was also another one "The Secret Life of machines with Tim Hunkin." It was a bit quirky and rustic, but also very calm and just pure genius in demonstrating how stuff works. If only we had more stuff like that!
@@martinda7446 Computer History Museum in Mountain View, California runs a marvelous project to preserve the heritage of semiconductor industry by interviewing people whose work contributed to it. And then they publish these lengthy, very detailed "Oral History" interviews, full of technical details, on their RUclips channel. They also have a library of searchable transcripts on their website. Something like that needs to be done for other crafts. Dan has so much experience, so much to tell both about engineering and about life -- it would be a captivating tale for many people interested in technology and its real history -- with all the ups and downs that come with trying to create something new.
Oohh yeah, the Professor is back... What was I doing?? Make a coffee, sit back.. And watch whatever he will impart! Thank you. Looks like a very slick set up you guys have got to market, wish you success. It seems to me you would still need 'the back room' machines and machining skills to finish off most of the parts critical dimentions. But a nice step on the evolution of manufacturing. Ps, I still dream about making a lathe like yours. That vidio was such a tease. Carl from Oz..
Hello Mr Gelbart, I just recently found your video series, very nice to see more form you. Please continue the videos, especially for people who would like a more comprehensive understanding. Looks like 3D printing metal parts have become mainstream, not a novelty anymore, very cool. I guess "bigger" parts could also be made with the sintering method, by "water gluing" lol many parts togather. If then you have a big enough furnace to heat it afterwords.
We use SLS to build jet engine fuel injector nozzles, which removes about 30 manufacturing steps. In exactly zero of the company's literature do we show the scaffolding from the SLS process! We make it seem as if the part falls out of the machine ready to use!
Sir Dan, nice to see your video again!! Thanks for your video series, great improvement in my knowledge! It was almost impossible to build my first 3d printers, based on steel welded frame, without your video lessons. Many thanks!!!
Thing I love about this guy is his flat out honesty about being a partner in a sintering style 3D printer company. How many RUclips creates do we watch that either flash name brand tools constantly throughout their videos, constantly name drop the brand name as if there is a minimum amount of times they have to drop the manufacturers name, flat out stop the video flow to introduce us to the sponsor of this video or (the ugliest and most disgusting types of all) flat out take over a channel and the creater becomes a salesman for the company and every video is either related to the product or the product placement throughout the video just wrecks that channel?? It'd be such a breath of fresh air if RUclips creators would be that honest about sponsorship.
I can't believe it, just a day ago I started watching your building prototype series again, wondering if you'd ever upload again and the next day... i thought i must be dreaming. thank you for all your videos, they are absolute gold, i can't emphasise how much they helped me!
No talk about hybrid machine? I think the future is the combined additive & subtractive machine center like Mazak and DMG-MORI have come out with last year.
So here's the deal... This guy is either an ALIEN or a GOD. Meanwhile I'll be working on a 3D shrine of his image and cranking up my lathe at sunday noon in his name.
great in depth info and dont worry, I found it very balanced, so you made sure that an eventual bias is not obvious. I do worry a bit with what you say at around 37:20 => we dont realy know what is in the gasses released by burning off support material.. as a M.D. in oncology I shiver at that thought :s
dr_BD yup a gas spectrometer reading then a safe out gas solution would be handy for across board liability. The same was needed when carbon fibre was in development and health dangers weren’t realised. A bubble through water filter at an additional neutralising gas symbiosis on the outgas.
Dan I love your videos and this one in particular. I could get really interested in one of these. However, since you are on the board of directors for this company, please implore them to standardize the packaging and interfaces for the material cartridges. They could be made to an international standard just like a light bulb. Alas, if this is not done I fear that sales will be negatively affected. The buying public has had a snoot full of the likes of Lexiark, Cannon and HP for the litany of inkjet cartridges out there. These should be made to a standard so a failure of a company doesn't leave the customer stranded for consumables.
Thank You for Coming Back ! You are Master of Your Trade and we all require your Knowledge to be shared with us! Thanks for Posting a new video and I hope you post regularly .
Thanks Dan, a great video as always and awesome to see fresh content from you. This is my first look at this Rapidia system & it was very impressive. It seems to me size wouldn’t be a huge limitation for customers with specific requirements if a large part was broken down, alignment features possibly added, and the components pre-sintered/re-bonded as described. The inert furnace volume then being the limiting factor.
Hi Dan, I had the good fortune to learn from you at ASML in CT. Those lessons specifically helped tremendously as I transitioned from precision mechanics to medical devices. Your reach is far! FYI, we have been using 3D printing in metal and plastics for production. Printing allows us to make organic shapes which helps us create complicated flexures with less parts. It also allows us to integrate industrial design into our products while avoiding the high cost of injection mold tooling. Our most successful implementation of 3D metal printing is to create micro structures similar to bone which allow better bone ingrowth into an implant.
Mr Gelbart, I have watched your 18 part series on prototyping at least 3 times. While I'm not in the prototyping business, I find tidbits of your knowledge appearing in other places. Thank you.
At Fokker Aerostructures in 2010 (I worked there for a while) electron beam additive manufacturing (Sciaky) was (informally) investigated for what I thought were the F-35 titanium flaperon spars which were then forged on one of the super heavy presses which are in the US. A batch would have a lead time of over a year. Additive manufacturing by melting (the Sciaky system is really a MIG welder) I knew would pose great difficulties.
I was recently at a trade show where Desktop Metal Studio was being demonstrated, their price point for an "office" system was around $250k AU using FDM rods with binder, a washout station and a separate sintering station.. they claim to have a very specific "scaling" process to ensure the green parts are the correct size so that post sintering the finished part is correct size. I was very interested to hear about the waterbased binder re-activativing to join sub assemblies together, very clever! At the price point you discuss this is a very enticing offering!
long-term (long long term). This process would be perfect for manufacturing in outer space. No supports required, can go as large as you want without gravity-induced sag, inert environment for sintering. Definitely the future. A few hundred years from now I could imagine all manufacturing is done in outer space in giant 3 dimensional factories without people. The raw material cost, tool-path and energy costs are the only factors that go into calculating the cost (think an Amazon AWS type service). You provision the tooling required and get the object (tea pot or cruise liner) you want. Thanks to gravity, delivery should be relatively cheap too.
Hi Dan nice to see you back thought my computer was having issues that something has to be wrong here, nice to see you still favoring your lathe build over this 3D event watching anyways. Multi-metal additive manufacturing is something we have seen work that is amazing to us. Great to see you looking well. Thank you, Lance & Patrick.
I discovered Dan's video I think 2 weeks ago (from AVE). Was disappointed that videos were discontinued. Great to see new videos and surprised by this small coincidence.
3d printing is generative, it builds the part. cncing/machining is discriminative, it removes internal features to end up with the part. Smaller volume = faster printing
Dan, I hope you are doing well. Just watched all 18 episodes of your series. It is probably the best series about r&d or prototyping around. Watching your videos I just want more and more. 10/10 rank stuff !
I think one reason medical uses laser systems is you can be certain no materials other than the metal end up in the end product, as no other materials are added at any point in the process.
Does it produce alcohol? Its the only explanation for the cost. The rapidia website fails to show a price, just the standard BS, "contact for quote". A quick search shows a 200000 price tag.
Hi Dan, keep up the great work. I found your channel because of your high precision lathe/grinder video and I'm hoping you make more videos, because you're very good at explaining things and you clearly have a lot of valuable information to share. Wish I had a professor like you!
A new Dan Gelbart video after 4 years? There's no way this day could get better!
He's back. Cant believe it after discovering him month ago.
There's a reason I subscribed to his channel
That is a failure of your imagination.
WOW about time, more please.......
Thank you Dan, It's a good day. Any more Air Bearing lathe videos?

I am so happy to see you after so many years. You made my day sir.
Dan man, your previously videos were so unique and information rich, I'm so glad you decided to come back from the future to give us another lesson.
I am a retired mechanical engineer but I have to admit, I learned a bit! Thank you very much, Dan Gelbart for this YT video.

Love your videos, please don’t disappear again
Interesting video, sintering at zero gravity might allow for larger objects?
Just have to get your machine into orbit.
Or reduce sag potential by about half by submerging parts in an ionic liquid inside a vacuum chamber.
You would still need to vent off water vapour from the binder paste though.
Happy to be witnessing history! Thanks for the new video Mr. Dan
I did a double-take when Dan Gelbart reappeared in my notifications! Best wishes with your new enterprise.
Wow happy to stay subscribed after all these years!! Welcome back!!

The 3D printer looks like a modified version of the BCN3d sigmax !?

I thought laser sintered parts had structural weakness compared to cast.
So, after accounting for the shrinkage, how tight can you get tolerances with this method?
I think he said something like 1% of the size of the original part. That's why you might have to machine them back to precision.
@@JavierChiappaIf so that's significantly worse than DMSLS.
22:47 damn he didnt have to diss metals like that

I urge you to check out Tim "The Secret Life Of Components" Hunchin's videos. Very different budget and viewpoint.
More than 3/4 of an hour and not once did I think this was a long video.

'My name is Dan Gelbart, I have been very busy making a 3d metal printing machine these last 3 years...' 😂😂😂
New video!!? Thank you thank you thank you :)
thanks for the full disclosure
3d printing is generative, it builds the part. cncing/machining is discriminative, it removes internal features to end up with the part.
Smaller volume = faster printing
Dan, I hope you are doing well. Just watched all 18 episodes of your series. It is probably the best series about r&d or prototyping around. Watching your videos I just want more and more. 10/10 rank stuff !
I think one reason medical uses laser systems is you can be certain no materials other than the metal end up in the end product, as no other materials are added at any point in the process.
Does it produce alcohol? Its the only explanation for the cost. The rapidia website fails to show a price, just the standard BS, "contact for quote". A quick search shows a 200000 price tag.
Hi Dan, keep up the great work. I found your channel because of your high precision lathe/grinder video and I'm hoping you make more videos, because you're very good at explaining things and you clearly have a lot of valuable information to share. Wish I had a professor like you!
