The use of 3D printed foundry patterns for aluminum casting with oil bonded sand molds

Jorgensen, Tavs; Lightfoot, Sonny

Abstract

This paper presentation outlines early-stage results from research into the use of low-cost 3D printing to create foundry patterns for Aluminum metal casting with oil bonded sand molds. The paper outlines findings and observations in relation to the practical challenges in using Fused Deposition Modeling (FDM) 3D printing for this application. The paper provides observations from first-hand practical investigations of the complete workflow including pattern design, fabrication via 3D printing, mold making, casting and fettling/finishing of the parts. Observations will be delivered as researcher reflections of the process and include strategies and approaches in relation to the use of patterns with the particular surface texture that is characteristic of FDM produced parts. Numerical data will be provided to assess final aluminum part accuracy in relation to the printed pattern.
