Casting things from Silicone Caulk in 3d printed molds

Yesterday I tried an experiment.  I wanted to know if you could cast Silicone Caulk in 3d printed molds.

The answer?  Yes!  I used PLA for the mold, Petroleum Jelly as a mold release, and some Acrylic paint to color the part and provide the moisture required to set the silione.

Unfortunately I underfilled the mold so my part was unusable.   It is still a resounding success though.

On to the pics!
