Volume Production 3D Printing. So fast and Save cost~🤩

Six years ago this method was almost twenty years old. It blew my mind back then, but it has never actually managed to make it widely to the market and there is a reason for that. Actually more than one.

I still remember as a kid me and my brother used talk that someday they will make a 3D printer.

Okay, so how do you clean the lattice sections away if they are fused metals? When these were made from plastic, you could carve them out with a sharp pocket knife. I'm thinking you need something stronger than that working with metal. Also, is it still possible to heat treat these (essentially cast) parts? Or is this unnecessary?

@bruhmania7359

The support structures aren’t needed but if used are cut off with power tools. Inside lattice fill doesnt exist because parts are solid

You use carefully designed "teeth" to minimize the surface contact. Then you break them off with a hammer, chisel, etc.

Genuinely curious, but what's new about this? The convenient programming? SLM has been around for more than 20 years, no?

Not really, SLS was, which is primarily plastics. Of course, SLS used metal balls in binders to make a part and then burnt off the binder which left a porous metal part that needed to be infiltrated later. Not so accurate or practical. SLM directly melts metal powder. While the process has been there for 12+ years, with the advent of more powerful lasers, higher temperature materials can be welded with higher densities and hence the excitement

So awesome!

elijah mikle though you are buying specially prepared powders instead of e.g. cast or rolled blocks, sheets etc. And this is really slow vs. molded, stamped, etc. parts. It's another manufacturing process, and will be the best choice for some (not all) applications.

There is a chance in the future that we can easily process raw material to special powder. And improving additive machine into next level, every home have one, There is no physic transaction but design/cad. We can print entire vehicle with just single click.

That's amazing.

I'm surprise they need support for it being powder SLM, guess it'd be similar to SLS but perhaps the extra heat means it's needed... feels almost like a step backwards to have to use support material.

Does it need the inert gas? What would happen if there was vacuum instead?

Very surprise. But I have one question. If make the impeller by using the this process, it looks like a included the small hole on the blade. In my understand, the cavitation occur most likely on the small hole. Are there have any solution?

Very beautiful and nice

love it!

What kind of tolerances do the parts come out?

Basic question. How to Remove the supports and the print from the Build plate?

Incrível! Maravilhado!

Why is there a need for support structure under the blades? Doesnt the powder provide enough stability to hold the blade while sintering?

It seems like you could literally have a dozen lasers working at the same time.

Super cool!

this is so great discovery

can it do an automotive cylinder head fit for machining? what type of price range?

I think what would be really effective is printers that can make highly detailed molds for casting metal objects that would normally be difficult to design, set up, cast etc.

The only thing you are going to see these used for is creating thin-walled parts that can't be easily machined on conventional machines. They will be out of the price range for any kind of independent workers, hobbyists, and will only be profitable for small runs of highly complex geometries. They are also slow. That's just the nature of additive.

It is actually used to build moulds that need to be tested as it is cheaper to make it this way than make an actual mould. It's not ideal for mass manufacturing though. The machine itself costs about 500k and that's for the smallest in size (500mm table). You can certainly build things that cannot be built in any other way though. It's truly remarkable, but it does lack the surface quality and tolerance.

so you vacuum the metal dust manually in a one million worth machine. Cool.

ARE THE SURFACES UNIFORMLY SMOOTH AND IS THE TENSILE STRENGTH THE SAME AS IF IT HAD BEEN CAST FROM ONE PIECE OF MATERIAL?

this kind of machine is power hungry..

Several bits to know. Laser sintering was one of the first 3d-print technology's. This is very old news. Laser sintering is astoundingly energy hungry! For every watt in the laser beam, ten other watts had to die. Then there is equipment cooling... Parts made by this process are going to be porous and less dense than cast metal or machined parts. They will be far weaker, and being porous, they can wick up all sorts of liquids. Internal corrosion is a thing with such parts. Nothing on the surface, rotting from the inside. The surface of printed parts is rough, so you have need for metal forming/finishing tools. The equipment is NOT something you will ever see on a desk-top; 440 volt service, connections to water/chiller, drainage. And you can't buy one without a training certificate at the job site! Yeah, this will solve everything!

No porosity. SLS is DMLS is SLM etc. They're all the same, each company needs one to call their own, and all of them have achieved nearly zero porosity. With the proper heat treatments, these parts are some of the best you can make regarding materials properties, a leg up on castings.
