Curing the Surfaces

I now have three rapid prototype prints of my sculpture for the SculptCAD Rapid Artists Project. Even though they are printed, they are far from finished.

To start with, there are a few issues with the material they are printed with. The surfaces are sticky, and the sculptures which should be hollow, are filled with uncured liquid printing resin. I think the drain holes were not large enough, so the liquid could not run out before it started to congeal. The original design was counter balanced to allow for the extended neck, but since they are now more or less solid I have had to cut into the heads and remove the congealed printing resin and then patch them.

After clearing the surfaces with denatured alcohol, the sculptures spent 24 hours under UV lamps to speed up the curing of the resin inside and out (see photo). Unfortunately this process cause the resin to change color. When combined with the bubbles and patches, I don't think I have any option other than to paint them. I am thinking black flock.
