Decade old on this, but 3D printing is amazing

I'm a commercial GC and just used Sketchup and my local library's 3D printer to manufacture some simple parts I needed for finishes and saved myself $300. Technology is amazing guys.

Except it can't do metal.

wasn't it recently discovered that some genius somewhere (NY?) was printing 3D guns and "returning" them in a weapons buyback program, to the tune of decent 5 figures?

Well, not in a cheapo hobby model printer. I believe turbine blades are "additive" manufactured now. In other words, 3D printed.

Which is impressive because of how tight the tolerances on those things are.

Great way to build Christmas ornaments.

isnt there 3d laser cnc machining? uses a block and water jet? ive seen them before, but dunno if they considered 3d printing or not?

We used to make oragami by hand when I was a kid. Basically the same thing as so Called 3d printing.

Additive manufacturing with metal, plastics, rubber, etc. is common. Along with other composites that have properties more advantageous than metal in many ways.

Yes there is such a thing but it is not 3D printing.
Look at it 2 ways. You start with a block or metal and whittle it down to what you need - traditional machining.
Or, you start with nothing and add material into a pile to create what you need- additive manufacturing ie 3D printing.

Sure you can using various types of powder bed fusion like direct metal laser sintering, selective laser melting, and electron beam melting.

My son does theater and I designed and built some props for them to use with a 3d printer. They really are amazing.
I just bought a Creality Ender SE. There was almost no setup involved and it prints perfectly. I was told yesterday they forgot some part to a costume. I designed it in fusion360 and was printing it 10 minutes later.

Some suppressor manufacturers are 3D printing titanium. Pretty cool.

3D printing of metal is incredible, but an often overlooked aspect by hobbyists is that the finish isn't good enough for sealing or mating surfaces. In nearly all cases there is still required machining on the prints for usable parts. For very complex, one off parts it is viable, but it has yet to replace castings for mass produced parts because of cost.
