Chipfuzer DIY 3D metal printer by Mark Miller

Chipfuzer is a project by Mark Miller which uses metal chips / shavings / chips left after sawing metal plates and welds them together. It is basically computer controlled welder that welds 3d metal objects.

Mark writes this about his machine:

"The printed parts are metal. I am using high voltage and electrostatic depositing.....sorta.. in a bizarre looking chamber with a rotating building pedestal, a hopper with a tube of fine metal particles(from my bandsaw), and did I mention high voltage? Lots of snapping, popping, and sort of a welding sound....but its fast. The shapes are pretty simplistic to start off, and as can be seen grainy finish, but much to my surprise stable enough to sand and machine a bit.
In the very early stages, will report more later....."


I asked him about this machine and he wrote me this:

Right now still a work in progress but getting better every day. I am now designing safety features in it as it uses rather high voltage. I have been making electrode redesigns, HV power supply filtering(to eliminate RFI) and hoping to scrounge up some more electronics to make a second machine. The last few days I have been designing a 3D scanner that will scan parts to be made on/for this machine.
When the machine is ready for primetime, I have every intention of open sourcing it.


More detailed technical information about it are unavailable at the moment.
I'll keep my eye on this cool project and I hope it grows. Metal 3d printing would be great step forward for DIY community.
