3D Printing with Fire and Iron | Making a Solid Multifix Toolpost Riser

Today, we’re designing and 3D-printing a casting pattern to make a solid toolpost riser for a Multifix quick-change toolpost on the Grizzly G0602 lathe. The plan is to delete the compound and replace it with a solid block of cast iron to improve the rigidity of the lathe and add a little style and flair at the same time. We’ll design the casting pattern in Fusion 360, print it on the Elegoo Mars 2 Pro 3D printer, and send it off to the foundry to have it rammed up and cast in gray iron.

The casting will be done by Clarke Easterling at Windy Hill Foundry: https://windyhillfoundry.com/
