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
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.
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!
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.
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.
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.
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!
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.

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.

Was imoressed how he shared anlot of details only to tell that "the additives are the secret souce". I hatd expected that everything actually is patented...
@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.
"This will be my next ender 3 mod." Other guy : "alright?"
🤣
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!

@@NathanBuildsRobots Yeah the boundary material is very clever!
This is by far the most scalable metal printing process I've seen.

Amazingly beautiful method of metal printing.
At this point someone is going to make an Ender 3 to Metal Paste printing conversion kit that you can Buy.

Proper Printing has been working on SLA paste printing with an FDM machine. This would be a logical next step.
Love this kind of content
Brilliant conclusion!
Very cool process

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
You are a great interviewer
Thank you!
Oh this is cool! a nice alternative to SLS
Fascinating!
Very very cool
the reduction in waste compared to SLM is orders of magnitude. hopefully they will go for the consumer market

might they ever use the crcop42 metal for a future metal 3d printing paste?
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.

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.

Everything is cool but what about the energy consumption?
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?
Awesome! :)
can you actually print hollow infills (say, 20% cubic infill or honeycomb) unlike with powder bed fusion?
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.

This is kewl
dreams comes true
Looks like their printer was based on a BCN3D product. :)
He should have printed a benchy 😁
Imagine a failed print 😐
It looks pretty reliable, look how clean the layers are
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.
1,400 Celsius? OMG
I can't wait till shit like this is affordable. Be able to print automotive/motorcycle parts that are discontinued.
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.
Was imoressed how he shared anlot of details only to tell that "the additives are the secret souce". I hatd expected that everything actually is patented...
99,000$ Bruh.. 😟
That is actually pretty affordable compared to most metal 3D printers.
