Metal Parts from 3D Prints

You can make precise, durable, shiny metal parts using a 3d printer and silicone casting - it's easier than you might think.

This is a tutorial on how to cast low-temp metal alloys using 3d printed molds. The process involves common tools and supplies - a 3d printer, silicone rubber, a hot plate, stovetop casting alloy, and a dollar store skillet. I used this process to generate locking plates for my Flat-Pack camera arm, but the same method can be used to cast more than metals - anything from chocolate to plastic, with the accuracy only limited to the precision and resolution of your printer.

Crystal Glow Knuckles

Glow like a firefly, sting like a bee

Ok, maybe not sting like a bee. With these squishy cast silicone crystals, it'll be more "sting like a gummy bear" but that's part of the charm. This 3d printed Pro Trinket powered NeoPixel ring contains all the brains, battery, and lights to put on a stunning show.

Soft Quadruped Robot

3d print your way to a walking quadruped with no hard moving parts

This squishy robot walks using only two inputs. You can make your own using a few easy to find materials and some 3d prints.

Silicone Robo-Tentacle

Build your own soft pneumatic robot using 3d printing and silicone casting

This squishy tentacle robot has no hard moving parts. It's entirely powered by air pressure. If you've got a 3d printer chances are you can make your own working tentacle in a matter of days.
