Rapidia is a company out of Canada specializing in 3d printing metal parts using a slurry of metal particles with water. This mixture behaves a lot like clay, and have some very interesting properties. One of the best things about it is that it can be printed at room temperature on very compact machine, thought it needs to be sintered in a high temperature oven afterwards.
The great thing about their printer is that it combines the strength of metal parts with the simplicity of operation, similar to a typical FDM printer.
Rapidia provided me with an axe head to say thanks for covering their booth at RAPID+TCT. Thanks Rapidia!
This video was filmed at RAPID + TCT 2023 in Chicago
"This will be my next ender 3 mod." Other guy : "alright?"
🤣
Metal printing is advancing at an insane rate. I don't imagine it'll be long until this is relatively affordable at this point. Using standard 3d printers as reference in terms of 'affordable'.
Yeah that is insane that they are printing metal using what is essentially FDM printer hardware.
@@NathanBuildsRobots This is the future, as in this year. Revealing the niches of this process is fascinating. The key seems to be good interviewees that know their stuff, and can incorporate it into the narrative without sounding like they're selling Eskimo's ice cream.
lol
I'm convinced that in the future, instead of buying some spare parts, you are going to pay for the part license to print a number of times.
This is by far the most scalable metal printing process I've seen.
You really picked up a lot of very promising tech info for use functional 3d printing folks. This and the resin glass are truly amazing.
Thank you gitss, if you end up buying one tell them that I sent you :P
This is extremely cool. While still expensive, you can see how the cost of this could come down rapidly with cost saving measures. Nice interview!
Definitely a nice product, it looks quite simple to operate. Other metal processes require alot more careful consideration of support material, since you have to grind it off
@@NathanBuildsRobots Yeah the boundary material is very clever!
At work we deal with the polymer base metal filaments (like the BASF Ultrafuse line with around 90% metal powder), the idea of sintering the part that is basically FDM printed is genius, the issue really lies on the sintering itself, that's the whole magic of the process.
Sintering is not a new technology, it is actually 5000+ years old. Clay pots are hardened by sintering (sounds like you already knew about this stuff but explaining for the general audience). It is a very cool process that I would love to do a special video on sometime. Basically small particles melt and fuse together below their melting point, because of surface energy. Which sounds like a hell of a hand-wave of an answer. A material scientist would be able to provide a much more insightful explanation than I can.
At this point someone is going to make an Ender 3 to Metal Paste printing conversion kit that you can Buy.
Haha, I made a joke about that in the video. It is pretty similar to a ceramic 3D printer, like the Tronxy Moore 1 which I reviewed.
I think in reality you would find it much harder to do than you think. But those parts are so awesome. Those stainless steel alloys they are using are no joke - insanely strong stuff. And it print parts relatively fast.
I'm a machinist with an almost ready to retire boss and he's just now coming around to seeing me print resin and fdm. now if only what op said , I can convince him with it 😉
Machining those high strength Stainless, inconel, and Titanium alloys is not fun at all. Additive manufacturing methods like this are making those alloys a lot more accessible, and also making weird internal geometries possible. The future for this stuff is only going to grow!
Proper Printing has been working on SLA paste printing with an FDM machine. This would be a logical next step.
Ultrafuse shrinks by 17% and this paste shrinks by "about 13%", I can see parts with high tolerances needing further post processing in the form of machining to get them to the correct sizes.
Yes , that correct ,if yuo need precision yuo gone need to cut there or there a "little bit" , but its very diferent adjust a metal part with a lathe or some grinding machine , that make the part in a cnc machine , thats take much more time and adjusment i think , and there e are part yuo cant do in a cnc machine , so this thech have a good place there , like the SLM machine that fuse metal powder , tgey can make bach of metal parts with a grat desing , i saw that a metal brake for bikes in Titan workshop , search in yuotube
The crazy part was the green part post processing. I imagine it would be very easy to drill holes or smooth the parts out while green. But for actual precision and high polish finishes it has to be done after sintering.
If they have good software support in the form of plugins or their slicer, it should help greatly with that issue.
By calculating correctly you can get very high precision
I'd love to combine this metal paste approach with an SLS laser. Put down a paste layer, dry it, sinster it with an SLS laser, then put down the next layer. Gets rid of both the SLS post processing stage AND the sintering step these folks have to worry about.
Love this kind of content
Oh this is cool! a nice alternative to SLS
the reduction in waste compared to SLM is orders of magnitude. hopefully they will go for the consumer market
Yeah that is a good point, you end up using nearly 100% of the printed material instead of having to process a giant bathtub full of highly flammable metal powder every time you empty the build chamber.
You are a great interviewer
Thank you!
Very cool process
Brilliant conclusion!
Fascinating!
Very very cool
He should have printed a benchy 😁
Imagine a failed print 😐
It looks pretty reliable, look how clean the layers are
Awesome! :)
can you actually print hollow infills (say, 20% cubic infill or honeycomb) unlike with powder bed fusion?
Everything is cool but what about the energy consumption?
dreams comes true
Looks like their printer was based on a BCN3D product. :)
This video is night and day better than the previous video I commented on. The question is: Why? I hope you're give that some thought.
Certainly, I appreciate the criticism Corliss. Constructive, not just being rude.
Producing videos is all about telling stories. Sometimes the story gets lost in the grass along the way, but in at least half of these I have some real questions, both to get the interviewee talking and to learn more for myself, and help the audience learn more about these amazing technologies.
@@NathanBuildsRobots never let your questions pass. Stopping the interviewee from speaking puts the power back in your court. Always try to make work that is important somehow. Even if you’re the only one who cares that is better content than any viral video that appealed to our baseless so-called values. If a story takes you over follow it to the end of the earth if need be. But take those you love along no matter how hard they object. Anything that enlightens you will set good people of fire. You can go anywhere and do anything with a crowd of burning people behind you. It’s Mark. Corliss is my last name.
I can't wait till shit like this is affordable. Be able to print automotive/motorcycle parts that are discontinued.
So... kinda like when doing PMC paste with a plunger... how there are no patents on this because this has all been done before already.
I don’t have the time to look at all of their IP portfolio to see what they have/haven’t patented.
But applying solder paste to a circuit board isn’t exactly the same thing as building a 3 dimensional object. I’ve applied solder paste and it never occurred to me that I could build a 3D object out of it, use higher melting point metals, then sinter it instead of melting it. Easy to connect the dots in hindsight though!
Im just waiting for the desktop metal 3d printers, 10s of thousands of dollars is something i will not have for something like this.
The expensive part is the sintering furnace. Would be nice to see someday.
Put in k1 speedy a glass bed plz it will help
Yeah, the mass production capabilities would be insane if they sped this machine up. But more speed causes more problems.
@@NathanBuildsRobots will you put glass then?
Oh, you are referring to the K1, not this video. Possibly, I will consider it. Going to compare stock K1 to P1P first.
So rapidia is selling a turnkey solution? No mention of the software.
I am pretty sure the company sells or provides their own software. It should be pretty similar to other slicers on the market. I thought the materials, process, and parts were the most interesting things at the booth, but I'll ask about software next time I am covering one of these events. Having a 15-30 second overview of the software would probably be pretty interesting.
Is the metal paste basically metal clay ( Atomized metal powder + binder(water) ). ?( Mitsubishi makes metal clay for jewellery)
I think so. The exact formulation and additives is a secret, as are the particle sizes and shapes.
@@NathanBuildsRobots just need to wait for china to copy it to make it more affordable I guess .It's not ethical but consumers may benefit what do you think?
This is kewl
1,400 Celsius? OMG
LOL, so many polymers can be used as a binder to retrofit your FDM with powder metals. Why would I ever buy one of their furnaces.
If this hardware and software package cannot produce accurate intended dimensions, this rapidia 3d printer *is useless.*
The parts seemed pretty precise and flat. There are couple of ways to counteract the effects of shrinkage:
1) Oversize the part by 10-20% so you print it larger, then it shrinks to the correct size.
2) post-process machine critical features. This is common with all types of additive manufacturing to meet tolerance and surface finish requirements.
Near-net shaping of parts has been around for ages. Anything that is cast or forged usually needs to be cleaned up via a milling or grinding operation, so the challenges with this process are nothing new.
Also, some of the high strength alloys they are using are incredibly hard to machine. So you get the ability to make non-manufacturable parts, and can skip a lot of time-consuming material removal. I think it's a great technology but I appreciate your concerns.
All sintered components that use a FDM process actually shrink, so you have to compensate with your model size. It's the same for UltiMaker and BASF Fuse material.

99,000$ Bruh.. 😟
That is actually pretty affordable compared to most metal 3D printers.
@Nathan Builds Robots That's because everyone in the metal printing field is greedy with patents. Printing plastic was similarly priced until the patents expired now we have 200$ Printers. It shouldn't cost more than a 2000$ to make an FDM metal paste printer and that includes the oven. If it was priced $2000-$5000 I could understand. But $99,000 is just greedy, patents and greed hinder human progress because smart people with money horde their intellectual property from smarter people with less money.
Do you have something against a ROI?@@THOR_THE_GOD
Cyberdyne
Nathan stick to the formula. No one owns one of these.
Lol not with that attitude! Just showing you the inspiration for my next ender 3 mod 😊
@@NathanBuildsRobots Rock and Roll it then!
