This was how 3d printing was first introduced to me back in middle school. I was at a local college to take part as the only middle school team in a high school robotics competition and they made me a piece to take home. Still in good condition after all these years. Also, our team wasn’t necessarily good enough to be at high school level, but there wasn’t a middle school competition. So we went there instead.

this has been around for a long time. all nerds or people in this industry know. The machine is very expensive and a lot of the technology is pattern or the company keeps it a secret.

Sintered metal parts are what make up the majority of moving parts on cheap tools. Things like gear casings or, in some cases, the gears themselves. They're strong, but if you stress or work them too hard, they break, and the tool is trash.

Most production sintered parts like you describe aren't made by laser sintering like this though. Instead they have a form kind of like a casting die which they use to press the powdered steel into the desired shape with very high pressure. Then they bake the part at high heat in an oven and the powder fuses into a solid part. The resulting part has good hardness and wear properties, and you can make complex parts much, much cheaper than with traditional machining proccesses, but the sintered parts are quite brittle and weak compared to a forged or machined part.

I have seen a few i wish i had one but those are expensive as heck !! I also seen alot that sell similar ones for for metal printing for car parts.

This was basically the origin of 3D printing. Filament printers came decades after I first saw any 3D printed object. So if you've never heard of it, it's basically because you wouldn't run one of those at home 😉

That seems like it would be a fun job to do- cleaning all the metal dust off the parts. I think you could probably build something to do it for you though so the job would not last very long

You can get a pretty nice one that prints all the materials for $80k that's NOICE.

Not the only process that does this, inserts for CNC machines are also made by compressing powder than heating the compressed powered for a day at high tempatures to fuse it together. It shrinks significantly in size from powder to solid.

You are correct, wearing gloves is recommended when depowdering SLS parts. However, we have some more experienced operators who prefer using their hands for by their choice. They will of course wear a mask still.

In 2007 I worked on one of those, just slightly different. The one I worked would place the powder and them inkjet print over it. This special powder would kinda solidify there it where printed, forming the 3D object. Then this piece needed to go to a furnace to curing, to get to a really rock solid 3D printed object. The fun part is that it could even be color printed, enhancing the appearance.

resin printers also use sls

And is more expensive by far

@@alex59292 For sure if you have only one machine. With SLS you can pack your parts very densely in the build volume - in fact it gets more economic the closer it is because you don't waste much powder (we place the parts close together with a so-called nesting algorithm). So small production runs can actually be pretty fast (and cheaper) compared to other manufacturing technologies.
