3D Printing METAL AT HOME! 

I always know if the website doesn't list a price but just says "Get a quote" then I can't afford it.

It wasn’t that long ago that 3d printing was pretty darn expensive, so maybe someday we’ll be able to make it happen. I am loving how the 3d printers and the desktop cnc machines continue to evolve and are constantly more affordable and easier ti use.

100 thousand dollars machine ,to print at home? what home if you have to mortgage your house to buy this 3d printer?

the idea of 3D metal printing is a great thing.. to have the ability to make shapes and objects that would take pain stakeing days, weeks not adding in the tools and skills to create some of these to print these out in about a day.. so many ideas can be thought of with this.. even the idea of 3d printing a small funtioning engine would come to my mind.. this is awesome and hopefully this will more come out for everyone to be able to do

This is amazing. I can see this becoming much more developed and practical in the coming years. Definitely gonna keep my eye out on it

when it gets to $3000-$4000 price range, then it'll be "at home", but that 82-85k price range is not doable 😅

I love the evolution of the 3DP world. You can see it advance rapidly in real time. Exciting times and always something interesting coming out.

Joel reminds me of a kid show host, such enthusiasm for 3D Printing. Never lose that spirit my friend. Stay positive, keep it real. Peace

I spoke to the guys at the booth at LTX they have plans to make it more "affordable". I think this one was 100-150k and they want to get that down to 50k awesome guys working then booth.

I remember when Dr. Dan Gelbart first introduced Rapidia sintering furnace in 2016 or thereabouts. And I loved his clips where he showcased his lab/workshop and equpment. I'm glad to see the project is still alive and developing.

"At home" is quite a stretch. Technically, i could have a whole machine shop at home if i had enough money.

Crazy to think Metal 3D printing is coming to the home. I got into 3D printing after getting a 3d printed titanium plate drilled into my ribs for a sternum reconstruction surgery. I never would have thought we'd have that tech at home.

More accurate to say it can print for the *price* of a home! ;-)

The other Joel needs something like this for his jet-engine projects

This is crazy cool. This seems like a great start to making metal printing technology more accessible (and hopefully affordable) to the masses

Small nit: At 4:20 the info box says the drying lamp uses UV light. That's not correct. It's likely using infra-red with a high component of visible light too since it's so hot.

I remember when my friends at a startup got funding for a ~$2m metal 3D printer and now we're in that

First time I'm the first to see a new RU-vid video !

Its getting there. We just need more of the manufacturers to compete with each other.

I remember a paper about a mathematical distribution of particles sizes that cam make a powder with 97% solids, yea, 3% water would do the trick. Nice job guys!

So what kind of precision can be maintained?

Oh man you were really getting inside that guys bubble at the start of that interview 🤣

Love your joy and enthusiasm always making people laugh. Keep it up dude.

I too sometimes have about 18% shrinkage.

Oh man, this is a video title I've been wating on for years, ever since I got into 3D printing. Very cool! Of course, this thing starts at about $99000 without the furnace, so you won't be using one at home unless you're rich or really, really want to 3D print metal at home. However, that is how plastic 3D-printing also started out, after which prices dropped over the years until the hobbyist could afford it. This is the start of that process for metal 3D printing

I had never seen ringing artifacts on metal parts 😂 . I guess they gotta tune their input shaper. Does it run klipper? 😂

100k at home? Thats industrial level. Anything marketed as 'at home' should be at 10k or less.

Did they say what the metal composite is? I’d love to see some strength testing.

Thank you. This channel helps me feel up to date and hopeful for future technologies!

Oh wow, remember that guy from the first MRRF who had this idea and actually was showing us all the parts printed with his paste? That's crazy that it took this long for someone to make an actual machine using that stuff.

Please loan Joel one of these printers for at least 6 months so we can see him make a bunch of cool stuff with it! As someone who has been 3D printing for about 15 years and has done a mix of industrial level 3D printing and home-based, I get that this is not for the average person who is buying a reality machine for under $300. It's still a huge deal that it's capable of being used in a home. I think saying that it can be, does imply to a lot of people that it's also affordable for the average person which is obviously not the case. Although these days the average person can't even afford a home. The first time I looked into getting something 3D printed was before there was any machine you could get for the home, and it was going to cost over $100 to get something printed that wasn't much bigger than a 1-in cube. And it would have been printed on a machine that I believe at the time cost hundreds of thousands of dollars, and the final result was still just plastic. So even if this machine costs $100,000 or $200,000, it's still a way better option for a small company or a wealthy home inventor than any other option. I don't see much point in complaining that someone offering the cheapest option is still too expensive. They've already beat their competitors on price. I think also a lot of people who haven't gone through the process of inventing something doing the r&d, and then the arduous task of actually getting it to market don't always understand that before the product even gets to market you may have spent years of your life and hundreds of thousands of dollars if not millions of dollars in development. You can't do all that and then put out a product for too low or you'll go out of business before you have a chance to build a large enough customer base that you can lower the prices. Even if the whole setup for this printer could be sold for under $1,000 (which I'm guessing is less than it even cost them to make it), I don't think the average user of a 3D printer would find this to be their daily driver unless they only want to make metal parts. So the market is pretty small for this kind of thing. Thanks for another great video, Joel. High-5!

I have a mighty heckin need

I'd like to know the difference in cost to binder jetting! good luck!

I haven’t 3d printed in years, this makes me want to get back into it!

Could you try Mitsubishi KyronMax? It's the strongest thermoplastic material in the world with 430 MPa of tensile strength and it can be used as a filament.

Metal products are a world of very specific material makeup. Professional kitchen counters have food grade stainless. Care engine blocks are cast from a specific aluminum alloy. Drill bits are hardened, high-carbon steel. Wrenches are different steel alloys. Some products are cast iron. Metals might be rolled, stamped, cast, forged etc. depending on the different desired strengths. Can this produce different metals or just the non-specific "metal" featured in this video?

BASF Ultrafuse 316L filament yall! It's pricey tho, 3kg spool will run $500, but it works in any 3d printer.

This guy is a close talker

Looks really nice, but with "Complete Hardware solution from $99,000" I won't be making metal Benchies any time soon! Still inexpensive compared to most other metal printers, apart from those that use standard FDM-based printers to make the green parts (Virtual Foundry, Bosch Ultrafuse, etc.). I'd love to see a deep dive in to the pros and cons of both technologies. It's interesting that they're working on copper (I see that on their website). There aren't too many copper printers. Your pop up info box says the drying lamp uses UV light. Surely it's infrared light?

Will they be giving you one so you can show it off more?

How well do the parts take to machining? This is the sort of printer that needs to be used in microgravity in orbit, to produce the lowest mass possible parts, that can be assembled in to deep space vehicles structures.

He said fully dense. So do these parts have the same thermal properties as solid metal parts? I want to 3D print aluminium and copper parts for thermal applications.

[Me being perfectly content with my life] ... I need a 3D metal printer now Thanks, Joel 🤣

I hope some day I'll be able to afford one of these.... It'd be super nice to print a turbocharger for the car, or whatever other parts I want. What we can produce in FDM compared to traditional milling, this is so incredible and allows you to create an unbelievable variety of previously impossible metal parts.

I'd be curious to know how strong these parts really are. For example if you've ever watched Forged in Fire, anytime there is a catastrophic failure where the blade breaks, they almost always look at the grain of the metal and can see issues with it that contributed to the breakage. With deposited paste, how might that be affected?

Minor critique, you seem to get closer to the mic after you hold it next to him and he looks a little crowded. Looks like a fun development though. How long till we have 'consumer sized' dlms? Id pay 10k for one with a cubic foot work space.

Finally something for a custom HPA Airsoft ;)

Very cool tech, once it can/if it can do aluminum this could really change high end restoration and custom car business. As is SLS printing is still cost prohibitive for anything but the highest end shops, this could change this. If it could do aluminum you could even do custom cylinder heads and such that SLS would be too slow/expensive to build.

Great stuff, and thanks for covering this! Have a great Christmas!

I'd love to see what Integza could do with a Rapidia metal consumer 3d printer, since he already makes rocket engines out of ceramic filament.

This would be a dream for prototyping. I hope they have a consumer affordable product within the next two years.

As a young creator designer that loves to make things such as Beyblades this is a very fun hobby but very expensive I like to give this product try but I don't know if my parents can afford it

It's getting there, the amount of up scaling and shrinking is still a little too imprecise for what I want it for. But it's close and still tempting.

Making car parts would be a really good use for this

Looks like a virtual foundry style solution of print metal in binder via extrusion with extra complexity

i wonder how they calculate strength of material, are there different options for heat treat

4:30 metal binder powder 3D printing and sintering versus... ??? ...really versus investment casting techniques ("lost PLA", lost resin etc) where you get excellent cast metal parts from the refractory ceramic coated 3D prints, crazy shrinkage is an issue with either... will be keeping an eye on RAPIDA for sure!

you definitely are a 3d printing nerd! Good video!

Could you talk about desktop Metal? It seems that their 3d printed metal and carbon fiber parts are of much higher quality. 2'400 MPa for their fiber parts versus 800 MPa for markforged.

Why toothpaste/chalk hardness and not PLA hardness? The green parts sound like they might have problems with handling on the way to the furnace

I hope one day we look back at FDM printing and laugh at how everyone use to print plastic.

How sintering achieves binding but avoids melting of part at same time?!

Is there any need for Hot Isostatic Pressing(HIP) stress relief? How do these parts hold up to heat treating? Any more shrinkage beyond the initial heating?

Sagging and Shrinkage. Things you also say when you are getting older.

Looks like the system Dan Gelbart was involved with the development of?

Dream is coming true

How much is the cheapest model???

Awesome to see. I wonder... was the power requirements mentioned for the printer, the furnace, or both? Because I can see people now going "finally, everyone told me it wasn't happening anytime soon" and in reality it being "well it's 3 phase power, you need 1 outlet for each machine, the paste starts hardening after opening so you have to use the whole thing or it goes bad, we only support certain metals at the moment (and while people will go "stainless steel is fine" and then discover that it's not the particular one they were expecting), and it's going to be pretty rough until you post-process it with a lot of grinding and polishing... which those who need/are semi-capable of doing metal printing NOW can do... while those who just want 'metal Bambu/Prusa/Ender-3' etc. can't do" and that's all before price comes into play. We hope cost comes down, though it depends on a number of factors. Plastic FDM costs are where they are because of competition and because people took the process and turned it into reality using wood, plexiglass, and cheap metal extrusions. So it goes from cheap to expensive, depending on features and company. This, and many other metal printers shown at this point, have a lot of R&D, technical development and limitations to overcome. So they start at a high price and unless people can do it with basic components (which room temp. extrusion is certainly possible) and/or there's competition, it will remain at that high price. So again, awesome to see. Looking forward to see them inevitably be shown again (and what they hinted at...), but "it's not happening anytime soon at a cost most people are willing to pay"

I wonder how you can maintain the precision of 3D printing with that 18% shrinkage

freaking cool.. I guess the only thing that sucks compared to the lazer welding style of metal 3d printing.. you cant print hallow objects.

I am curious, as to whether the meal parts that can be printed are of dine detail levels such as a model axial flow jet turbine engine can be created.

Some advice for this company, when people see videos like this they will go to your site because they are curious about the price. If you don't list the price and make finding the price a difficult thing; people will just walk away and look for something else. As soon as i saw "get a quote" i just closed the page, i don't have time for your games An example, i read some of the comments of this video and someone mentioned virtual foundry. I checked out their site and within a minute i have prices and that is more then affordable, now i am going to research that company and see what the pros and cons are of that system compared to the $100k-$150k systems. Point being is you loose potential customers by not listing the price and thats year 2 business school stuff here in Canada

can you tell about tolerances?

So will a furnace work or just theirs?

whats the strength like compared to forged steel? my, i got a lot of questions....

That's so cool. I want one !!!!

How much do these things cost for weak layered metal parts?

Looks like a repurposed BCN3D IDEX printer, and not sure if that’s a proprietary furnace also, but fair play to the paste system this looks less complicated to implement than powder

It would be nice if there was a UV light bonding material wit instant cure.

Imagine 3D printing metal nozzles for hobby rocket motors.

What kind of metal does it use? Aluminum? Iron? Steel? Gallium? What?

Kinda deal breaker if you get random size with shrinkage

Off topic : Must you have the mic thay close to his face ? It's just something that bugs me about interviews, weird,ik.

18% shrinkage is massive. No way to maintain any accuracy for engineered parts that need to fit together with that.

This video was lacking. I have to assume the system includes the scintering oven, but the website nor the video has details. Also a roughing price would have been nice.

Recently , I got some quotes for Binder Jetting... parts are still very expensive even when buying hundreds at a time... a 220 gram part in 316L for a one off was $270... for 500 of them was $110. Unless you are Nasa, GE etc the parts aren't comparable to traditional manufacturing. Good for a nice metal prototype but not feasible for small production.

Nice but axe will not be as strong as a forged one! Or is this paste bonded at molecular level ????

I was excited for this... Metal 3D Printing at home at an "affordable" price?... Visited the website and it said to get a quote... A google search of other people's quotes: $99,000 USD... I wouldn't call that affordable... Love the tech.... not the price...

why are you standing so close to the poor guy. invasion of personal space.

This is what i always wanted !! But probably is expensive still lol.

Hello, this is great. I am glad I stumble upon this video. I have a need to print a product prototype. Is that something that we can discuss? Thanks

Hi five bois!! I can't wait to get my hands on a metal printer!!! Anything is possible! 😮😊

So it makes sintered metal parts and so uses a cheaper process than a terribly expensive full metal printer. Is that right? Some engine parts are sintered metal so I was just wondering.

Seems really cool! Now I'll just wait for a company like Bambu Lab or others to make an affordable unit in a few years.

The finished metal is porous, right? I think it has to be because you cant have metal powder/paste with 100% metal content. How are they dealing with that?

Dam if this was 5 to 10k id buy one straight away.

I am curious if it is possible to print 2 parts separately and then bond them together so that they form one part in the furnace?

Good Stuff. 😄

Next comes 3d printing for edible organic paste. Like your metal paste but edible. The powder can easily include/consist of vitamins, nutrients and while the binding paste uses the same binding agents as found in living meat bodies (humans, cats, etc.). Flavours and colours can be chosen by the user through Mio style plugins which they stick into the machine. Without this you'd print a bland colourless hamburger. But it would contain the proper (or close) textures and nutrient and fat values found in a hamburger pattie. Vegies already grow fresh. Perhaps we can possibly curb the coming need to enslave disgusting mill worms to compensate for the ability to end the slaughter portion in our enslavement of cows for our need of hamburgers. Milk is a great source of animal fat (and cheese) that doesen't kill the cow. The "can you 3d print a fully edible hamburger?" challenge. Thanks for enduring my Ted Talk

🔥Cool tech. Mahalo for sharing! 🙂🙏❤️
