[Thomas Sanladerer] wanted to create some molds using 3D printing for concrete and plaster. He used a delta printer with flexible filament and documented his process in the video below. If you ...
This tutorial on how to cast metal parts from 3D printed silicone molds is a perfect example of how useful a 3D printer can be when you are looking to make a custom and durable metal part at home.
3D printing can more easily create prototypes of parts to test their form, fit and function with the rest of an assembly. Tooling molds and dies, as well as patterns for castings, are 3D printed.
