Hi everyone! I would like to discuss the pros/cons and engineering challenges one would face in order to create a 3D printer capable of printing in metal. I have created an open source initiative (linked to below) that deals with this subject, there is quite a bit of information I have amassed on the subject, so it is worth checking out... http://www.metalbot.org I am sure most people here have heard of 3D Printers/printing, perhaps some of you've had the opportunity to use them. From what I have learned, the two limiting factors with 3D printing have always been a - strength of the printed parts and b - part resolution. Hopefully it is possible to solve both of these problems by designing printer that works through a process called 'laser sintering' (although a few other avenues are being pursued). I would be more than happy to answer any questions to the best of my knowledge! Best regards, Jethro.
