Industrial Investment Casting With 3D Printed Patterns Using Formlabs Clear Cast Resin
This white paper presents the methods by which several established foundries were able to cast metal parts using 3D printed patterns produced by Formlabs’ stereolithography (SLA) 3D printers. It showcases the full process, detailing the use of latticed Clear Cast Resin acrylic-like parts to produce patterns that were easily integrated into typical industrial investment casting foundry processes without significant workflow or hardware changes. The included case studies also summarize their findings and show how using these patterns enabled the elimination of expensive and high lead time metal tooling that is normally required for the production of parts.
