Last month, I prepared a batch of small 3D-printed objects for the “lost ABS” process, some to be cast in aluminum and the rest in bronze. One of the pieces, a 3D-printed two-part mold, was placed in the kiln on Tuesday and cast with aluminum on Thursday. The other three pieces were all supershapes I […]
While experimenting with other traditional casting media and some 3D-printed molds, I began to wonder if it would be possible to use hot Victory wax (common in use at my university’s sculpture studio). Turns out, not only is it possible, but it works great! Hot as the wax may be, it turns out to not be hot enough to melt the plastic molds.
While experimenting with 3D-printing in mold-making and casting, I came up with a simple OpenSCAD script to generate keyed two-part molds from arbitrary STL models. These molds can be printed on 3D printer, then filled with all sorts of casting media from wax to resin.
Integrating 3D-printed ABS models from my university’s new Makerbot Replicator into traditional sculpture processes (specifically, the “lost wax” casting process). I learned that ABS plastic should melt and burn out in a kiln just as easily as wax, so I invested and burned out a small mold and cast it in aluminum with great success!
Working with my university’s sculpture program, I learned as much as I could about traditional mold-making techniques and processes in Fall 2012. I decided to try to integrate the university’s new Makerbot Replicator into these processes, beginning with creating open-face molds. Includes casting attempts using Oogoo and chocolate.
Since the last post, I have generated a few more molds and refined the OpenSCAD script a bit to be more flexible and easier to use. The main issue I was concerned with fixing was the nasty layer separation problem I was seeing in the first mold (large amount of splitting between layers of the […]
