Amazing 3D Printed Metal Parts!

Hoping hobbyist can afford printing these some day

3D printed fuel filters are the way of the future for the automotive industry

[DangrMouSe]

yup, that's a pretty looking solvent traps

[frankdelucey]

That's the best wind chime i have seen. Just need a few in wind chime lengths👍👍

Awesome! Now I can print my own oil filters at home!!!

For those wondering about DIY - the lowest cost way to do this is to use a laser cutter and cut thin sheets of metal cross sections, then stack them, and either weld or bolt it up. It's not perfect, but it's sub 2000 dollar "printing". Its slicing, but physical.

For 3D printing, lost casting. There are resin printers with prints that can be baked and the metal will fuse while the resin bakes off. Not great but Integza made rocket engines this way.
There are metal bearing filaments, like Prusa Tungsten PETG that are 70% high z (refractory) metal that will have some properties of the carried metal. Prusa also makes a fire retardant filament. The multi tool head XL printer can print within the print, and embed multi materials, so a flame retarding liner inside a CF reinforce nylon shell.
There are a small number of expensive printers that embed a continuous CF strand into the print rather than shredded CF. printers can go FAR with just exotic plastics. Don't believe the gov propaganda that just plastic makes you defenseless

If you want to go down the rabbit hole start with "orca" and "fosscad"

That thing probably cleans oil like no other.

This 3d printing metal could change the world if it was affordable at all

[Sacredheart]

I actually used to work with these printers at that company. Pretty cool stuff from my experience.

[Nomad_Wanderer]

This thing is a game changer for space related parts.

[Supernumerary]

Tesla valve with gas ports and passages. Various aerospace applications, but this appears to be intended for use as a very effective silencer.

The engineering in those parts is also impressive. They did a nice job with the metal 3D printing. I didn't notice any porosity

Metal 3d printers that cost 700-1200$ would literally revolutionize EVERYTHING it would open up creative endeavors in such a way to make it available to literally any one and everyone. One machine that could do the job of almost every tool in a professional machine shop.

[Alexa-Raine]

This made me realize that the machines I know, made of rubber tubes, wires, metal screens, rods, bolts, and washers, all of it separate parts, that we've been so extremely limited in our builds by the exact things this tech is allowing us to do.
The ability to print an engine, nearly all 1 solid piece.. wow

[jamesalewis]

Thought this was a rocket part at first. That is a really cool looking suppressor! I wish we could see the inside as a completed part.

[sinnwalker]

To all those hoping this reaches small individuals without a fat wallet, it will eventually, but whats more likely to happen before then is breakthroughs in material science, creating better materials than metal for certain applications, and for a fraction of the cost. As well as synthetic materials are more cost effective to 3D print. I'd say within a few years us smaller fry will be able to print reliable tools without needing a fortune, or rely on other entities.

Subtractive machining is not obsolete yet but this video is the future

[spoobiscooter]

Now the ai robots can 3d print clones of them selves

[luislongoria]

Robotic welders have been used to print entire rockets. Just wondering what the difference between SLS and SLM is

[alexsaam]

The way they weld powder into the part after layer after layer of powder being laid down. Unbelievable how they developed the technology to print metal without dispensing liquid metal to then harden. The next 20 years will be fucking awesome
