Title: Fractals in BRONZE
Post by: C.K. on October 16, 2013, 10:20:50 PM
Finally got this to work.  It's only a prototype, but I'm really happy with it ^^.  Let me know what ya'll think!!

The original was made in M3D and printed in 3D.  I posted up some pictures of it a bit ago.

Process details? From 3D print onwards? I'd guess print in either dental wax or burn-outable plastic?  :beer: :beer:

p.s. great piece BTW

The original form from M3D was brought into a CAD environment and split into two halves.  This was done so that the object would fit in the bed of the printer, use less print material, but mostly so that less bronze could be used on casting it.  The two halves were then molded in silicone rubber and then cast in modeling wax (a mixture of Brown Victory Wax and others).  The waxes were then molded in either ceramic shell or a resin bonded sand mold and melted out.  Molten bronze was then poured into the molds and viola!!  Lots of demolding and chasing of course, including welding the two halves together.  The piece was then patinated with a smoke patina (smoke from an oxy-acetylene torch on a waxed surface) and then buffed with a rough sponge to bring out the highlights.

So, yes, it was a burn out ^^.

As someone who as been burning holes in steel toed boots with the occasional splatter (bronze only once TG, steel splatter more than I can count  :embarrass:)since '75, I've got to ask was this you or under your management?

p.s. ceramic or sand or both?
p.s.s. spent > 8 years as sculptor and silversmith before I walked across campus and discovered computers  :dink:

I am curious as to the dimensions of this object.

    The original form from M3D was brought into a CAD environment and split into two halves.   This was done
    so that the object would fit in the bed of the printer, use less print material, but mostly so that less bronze
    could be used on casting it.   The two halves were then molded in silicone rubber and then cast in modeling
    wax (a mixture of Brown Victory Wax and others).   The waxes were then molded in either ceramic shell or
    a resin bonded sand mold and melted out.   Molten bronze was then poured into the molds and viola!!   Lots
    of demolding and chasing of course, including welding the two halves together.   The piece was then
    patinated with a smoke patina (smoke from an oxy-acetylene torch on a waxed surface) and then buffed
    with a rough sponge to bring out the highlights.        So, yes, it was a burn out ^^.

Based upon your description, I am assuming that this is not solid but hollow, how thick are the sides??    :D

From the wood grain in the base, I'd estimate it's maybe 6-10 centimeters long and half as wide at its widest points.

Both.  I wanted to see if there was a discernible difference in detail between them.  I couldn't see a difference.  Might stick with the shell though since it's easier for me, personally, to do.

And this is my own work, though it is towards a senior college art show.  I'm much more comfortable with material in my hands than I am with computers, but the computers are growing on me too ^^.

About 1/4"-1/2"?  The waxes cast pretty thick and I wanted to play it safe for the first round and make sure they filled.  Could definitely be a lot thinner.

Dimensions are about 7" in the longitudinal direction and about half that in the widest transverse (in and around what Pauldelbrot guessed).

There will hopefully be a few more of these coming.  Now that I have the rubber mold it should be simple to crank them out.  Planning on printing some different ones as well at some point.

Re wax mold, pour or injection? I'm guessing pour as this would be a little large for injection?

Correct.  This would be too large to inject, at least with the facilities where I'm at.

Thanks, Kraftwerk!
