Bending Steel With Plastic Tools

A video on YouTube. In Science & Engineering, a Krater category.

Summary by Krater

The creator tests 3D-printed dies and forms to bend sheet metal using a press and CNC plasma cutter. Through trial and error with various 3D-printed dies, sheet metal thicknesses, and spring-press setups, the project successfully forms clean bends and a complex shaped metal part for a Harbor Freight saw guard.

Spring-assisted metal press dies

What it concludes

3D printed tooling works well for making simple bends in sheet metal.
Using a spring press setup helps prevent sheet metal from bowing during the bend.
Thinner gauge steel or higher yield resin is needed to prevent 3D printed dies from failing under high compression.
