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.
