Casting Metal Parts into 3D Printed Molds

This video documents the process of casting metal parts in tin-bismuth alloy 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. This method can be used to cast a variety of materials, from chocolate to plastic, with the accuracy only limited to the precision and resolution of your printer. How to cast metal into 3D printed molds - I built a camera arm to document projects a few months ago. The joints are clamped down with rubber pads between them to prevent slipping, but I noticed the joint at the base kept creeping down over long periods of time (like while capturing time lapses). I decided to fix it with a locking plate like you’d find on C-stands, but wanted to avoid using a printed part that would chew itself apart after a few months of use. I built the locking plate using a method similar to the one I used to g
