Robinson Foundry crafted this useful brass kitchen gadget using a 3D printed measuring cube as a starting point. Like some of his other creations, he used the “Lost PLA” method to create a ceramic mold around the 3D print and then melted away the plastic. We wonder how accurate it is compared to the original.

If you’ve been to a firing range, you’ll see countless shell casings littering the ground. Seth over at Robinson Foundry wanted to put these to use, so he melted down the brass casings and turned them into custom coins. He created the shapes by 3D printing coin models, then placed them into a sand mold for casting.

Casting a Double-threaded Bolt

Robinson Foundry shows how he made a double-threaded bolt using the lost PLA method he used to make that awesome bronze skull. The process involves dipping 3D-printed models in ceramic, firing then, then melting away the plastic with metal. The design was inspired by a bi-directional bolt machined by Oleg Pevtsov.

Robinson Foundry shows how he took a digital 3D model of a human skull and used it to create a cast bronze sculpture. The Lost PLA method starts by making a 3D-print, coating it with a ceramic material, kiln-firing it to harden it and melt away the plastic, then filling it with molten metal and eventually chipping away the casting.

3D printed objects are typically made out of plastic. But as Robinson Foundry shows us, these computer-generated pieces can be used to produce detailed castings for more substantial materials. In this case, he output a 3D print of a menacing alien emperor and used it to create a ceramic mold for an awesome brass sculpture.
