Re: [CAD_CAM_EDM_DRO] Conductive ABS -- 3D Printing

3D Printing is called "additive machining", where material is being
added to the workpiece rather than removed.

I've ordered a Reprap Huxley complete kit from reprappro.com . It or
the Reprap Mendel kit is under 1000$. Also I've seen "Ultimaker" and
"solid doodle" "solidoodle"(?) which might be worth checking out.
Evidently all stem from the original 2007 Reprap which the inventor
made open source and put everything on line at www.reprap.org.

Now...

Has anyone used conductive ABS filament (w. carbon fiber)?
Has anyone seen a source to buy it on line?

I think conductive ABS battery electrode pockets with tiny pores on
the face(s) - sort of microporous or a bit bigger - to let the
electrolyte through but keep the compacted chemical powder enclosed
should make for an absolute revolution in homemade alkaline
batteries. I might even say make them 'possible', or at least
'practical'.

(I already have an improved chemistry that works - "MnMn" -
permanganate-manganese in 'moderately alkaline' electrolyte, about
2.2 volts. Dirt cheap stuff with the energy density of lithium ion.
See in recent issues of Turquoise Energy News:

That doesn't mean I've been able to make decent batteries, but I've
tried out the ABS pockets idea at a local prototyping facility, and
I'm very much looking forward to the arrival of the printer.)

Carbon fiber should be great for the positive electrodes. For the Mn
negative electrodes, ABS made conductive with zinc powder would be
ideal. So far I've been using strips of zinc (cut from dry cells) or
zinc plated pieces.

Coarseness of part resolution for the pockets isn't much of an issue,
tho it is for the case and one-way valve (no leaks - keep air out). I
plan to dip the valves briefly in methylene chloride to flow the
plastic a bit, to smooth them and make sure they don't leak. At
least, that's my present plan.

Cheers,
