At its most basic level, a 3-D printer is like an automated hot-glue gun programmed to spit out solid objects. The machines extrude layers of plastic into virtually any three-dimensional shape. Print whimsical garden statuary. Reproduce an anatomically correct heart with moving parts for your son's science project (actually, he could do that himself). Create a signature bookend, cookie cutter, necklace anything.

Just add glass/carbon fiber particles and/or composite materials to the mix to get metal strength.
I like this 3D printing. But the guy, R. Daniel Foster, having a partner, bothers me. Why would we ever consider a guy that has the mentality of a woman ever influence us?
OK, I just refreshed and there is nothing.
These things are amazing.
Or a really good engineer could come up with a resin impregnated sintered metal sort of material that becomes solid metal in a typical kitchen oven (or with perhaps a special oven - I’m no metallurgist). They use a similar process (without the 3D printer) already for some parts, I understand.
When will 3d printing be able to melt 4110 steel and titanium and print?
skip the 4110 and go with ‘smart’-steel ,
much thinner and lighter and 10X strong. just go to
your local nano-supplier in the future ;)
No, but the technology is capable of creating forging/casting dies.
And generally, they do it with powdered metals, and laser-sinter them together. . .
So much for the 3D printer, I want an affordable 3D scanner, so I can take anything from a chess piece to firearm parts that it will scan and then transfer that file to the 3D printer.
Mind you, the above video is an older technique: more modern systems directly laser-sinter. . .
The Austin guys at Distributed Defense are working on a 3-D printed gun. However, they lack a real engineer on the team (one is an electrical engineer, they need a mechanical one) as well as someone who understands material science (so they don’t end up with a gun that melts or deforms during use).
There’s real potential with the technology, but the “print a 3-D gun” effort needs more engineers behind it before it could become a reality.
I just hope someone takes up that cause before the bill to make 3-D printing of guns illegal passes.
3-D scanning has been used in dentistry for a long time. Not too “affordable” yet but it is like everything else. The early adopters pay the big bucks and the technology evolves and becomes more affordable within a relatively short period of time.

3D Printing of Magazines Used by Kel-Tec for Three Years

3D printed magazines have been successfully used by Kel-Tec for three years, I discovered at the NSSF Shot Show in Las Vegas yesterday. I talked to Tobias Obermeit, Lead Design Engineer at Kel-Tec, one of the most innovative firearms manufacturers in the United States. Mr. Obermeit said that “Without 3D printing, the PMR-30 would not have been developed, especially the magazine.” Mr. Obermeit informed me that a prototype magazine would be printed and then be used for 100 to 150 rounds, when they would develop cracks. The magazine would then be discarded and another magazine printed.
Form a mold, fill it with a metal/graphite fibers/polymer then add a liquid catalyst....the catalyst diffuses throughout and creates a solid object..
The neat thing is that the mechanical properties can be adjusted, in terms of strength, flexibility, thermal and electrical conductivity.
Wouldn't be too difficult to form a tapered cylinder with an inside diameter of, say about 0.45 inches...just sayin
Details with a google search of "metal matrix technology"
A company in Sweden, Arcam AB has an electron beam 3D printer that uses titanium.
