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

Explore the process of designing and 3D printing a casting pattern for a solid toolpost riser in this comprehensive 36-minute video tutorial. Learn how to improve lathe rigidity by replacing the compound with a cast iron block for a Multifix quick-change toolpost on a Grizzly G0602 lathe. Follow along as the instructor uses Fusion 360 to design the casting pattern, prints it on an Elegoo Mars 2 Pro 3D printer, and collaborates with a foundry to cast it in gray iron. Gain insights into 3D printing techniques, including printing large hollow parts and washing resin prints. Discover the tools and materials used in the project, from 3D mice to rapid resin and super glue. Watch the step-by-step process, from initial design to final casting pattern preparation, and learn how to enhance your lathe's performance and style.
