Jump Cut Final Model

19 custom molds made of laser-cut/scored acrylic and blue foam

The process involved laser-cutting the shell of the mold, as well as sculpting the inside void with the blue foam with the foam cutter (for this, I cut out chipboard stencils to help guide the wire). The resulting cast piece was designed to have 3/16″ thick walls, some with stairs and thresholds cast with it.

In order to cast surface patterns onto the Rockite, I laser-etched vector geometry onto the acrylic shell pieces. Acrylic was the perfect material for this, given its moisture resistance and dimensional stability – it doesn’t soak in water or bow out as you pour the Rockite in. It was also easy to extract. The acrylic pieces popped off, and I carved out the blue foam with a hand tool.

The Rockite pieces were assembled with the floor plates, made of 1/4″ thick spray painted MDF. Regular super glue worked.

The surface patterns can be seen on the cast pieces. The acrylic shell successfully made sharp edges.

I made the base out of plywood, spray painted to the same color as the floor plates to further emphasize the monolithic look.

In this detail shot you can see the surface patterns more closely, as well as the tapered edge of the threshold made with the blue foam in the mold.
