Chipfuzer V 2.0 of arc welder based DIY metal 3d printer

Mark Miller developed second version of his arc welder based metal 3d printer - here is the Chipfuzer V2.0.

Chipfuzer 3 D metal printer (version 2.0). This is the second prototype I made to improve the original design. It is smaller-12 inches wide, 12 inches deep and 12 3/4 inches tall. This model is fully enclosed and has safety features to keep the user safe from high voltage and harsh arc light produced on the build table.

The design also fully eliminates RFI produced by the arc process and makes a neat, tidy compact unit that can be easily transported and used anywhere.
The multicolored enclosure components are due to just having a little bit of each color paint in several cans on the shelf (low funds) and not representative of anything, or me trying to be overly "artsy".
I scaled down the X,Y and Z slide mechanisms but kept the build table the same as the first model, and the build size is nearly the same as the original. I am still tinkering with it a bit, but satisfied thus far with the new design.

This machine went together better and faster than the original, despite having to scavenger hunt parts, and make due with similar materials. In some places the unit is triple insulated, and the interior is covered in conductive coating and grounded. I think one more design and build will probably get me to a really good design for this idea, and will concentrate more on the software end of things from now on. Thus far I have made about a dozen prints with this, but plan on using this machine for most future experimenting.

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.

Printed metal part mounted on functional part (linear actuator probably)

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.
