Well, I imagined this would happen at some point...someone has now posted the Print-on-demand 3D printer file for both an AR magazine & a lower receiver.
Mag: [Only registered and activated users can see links. ]
Lower: [Only registered and activated users can see links. ]
[Only registered and activated users can see links. ] are really becoming more of a reality now, and they are doing more than just plastic parts, some of the industrial type machines can do metal parts too. They can do fairly precision parts now, here is a great example: [Only registered and activated users can see links. ]
The coolest thing is that in theory, with the plans/parts file a machine like this can print out the parts to make duplicates of itself(minus the electronics of course).
In case you are wondering, the printers are still a bit expensive from $1200 for a full kit to ~$2250 and up ready to run. Some are starting to be made in China and thus the price for an at home model is coming down fast. (see this one: [Only registered and activated users can see links. ]
Here it is in action:

One of the big name companies that does use industrial machine, Shapeways, is now offering 3D printing service in stainless steel.
The page below tell about the details/costs/engineering specs. I believe it could be do-able and also be strong enough, but I don't know how to evaluate the material specifications they list. Also on that page is a great video showing the process; they print the design using stainless steel powder and a binder, and then bake it in a high-temp oven to make it solidlfy. This is sintered metal, a process that is now being used to create many firearms parts by some aftermarket suppliers of 1911 parts, etc.

Update: Here is another cool video showing how laser sintering is used to fuse nylon plastic into a complex part. Eventually they will have higher powered versions of these that will do the same thing with metal powders to produce metal parts.

Thanks for the links, that's cool as hell seeing that happening.

Man I would love to have access to something like that, except with a metal powder!!!!!!! Man the car and gun parts that could be made!!!! Need an M76 receiver, just scan one in and print it out!!!

Ok, I took the plunge. I jumped into a Kickstarter project that is making 'affordable' 3D printers, only $499. My ready-to-assemble kit is supposed to arrive by the end of this month.
BTW, the guy who started this thought he would raise around $10,000 and build about 20-30 kits. Instead nearly 1000 people signed up and he raised $830k in about 25 days!

rocster, please let me know how this works out for you.money is tight right now,so i would like to hear from someone who actually bought and used one before i consider taking the plunge.this looks great. good luck and thanks.
Will do...
Update on my DIY kit is they maker is about 2 weeks behind schedule. Guess that means I'll see it by end of March now if all goes well.
