I know I must be boring everyone with all my 3D printing posts
I just think it's so cool that I've got to tell someone.. hopefully when 3D printers become a common desktop item in the home, I'll have a big collection of designs shooters from all over the world will be able to download and print for themselves.
If you're thinking about buying a printer, just be aware that these prints have been made on a very very expensive industrial machine. The printers you can buy for a grand or so really aren't up to the job in terms of quality at the moment.
The FormLabs1 laser printer (due out in March) might well be upto the quality, but there's a question mark over strength, oh and they're about $3500.
Prices will drop though and quality will go up and that will happen pretty quickly I reckon.
