Further casts in Jesmonite

More casting for the Space Rocks. Silicone moulds with Jesmonite and added white pigment, and then some slush casting.

Space Rocks – first casts

A series of photos showing the first attempts at casting the Space Rocks in Jesmonite, along with some further 3D printed parts to hold the circuitry and electronics.

Taking shape

The latest version of Space Rock #4, sanded and with the circuit board and powerbank holder printed for inside. Also shown is a version of Space Rock #1 printed in sections at 280mm wide, and coated with XTC 3D as a test as this print has lots of flaws – not least because the filament snapped just before finishing printing the front section, so I had to do a patch repair. Interesting to see how smooth this sands down.

First attempt at mould-making with silicone and casting in Jesmonite

A small test, mould-making from the lumpy Space Rocks created using Meshmixer, plus the resulting Jesmonite cast.
