Re: BrundleFab - a powder thermal fusion printer

I've updated my http://reprap.org/wiki/BrundleFab page with my new sheet aluminum layer head build.
I'm still waiting on the ceramic halogen lamp sockets and I2C thermopile, but in the meantime wanted to show off my 3-hour build.
(Well, it took about 16 hours of measuring and design work in OpenSCAD first, but the actual build only took 3 hours).
For utlra-light load bearing parts, such as my layerhead, cheap aluminum door signs ($2 USD at an office or hardware supply store) are a great way to make quick parts.
You can cut the stuff with household scissors, and with some knowledge of folding techniques, can be made relatively stiff for its thickness (0.010")
Hopefully I won't get too much thermal warp once I turn on the halogen, but if I do I can always rivet on an aluminum flat or two.
