3D printing offers an effective tool-less solution for investment casting patterns with Stereolithography (SL). As an alternative to wax and wood, SL builds patterns with a UV laser that cures and solidifies thin layers of resin. Stratasys Direct builds SL investment casting patterns in a nearly hollow structure with a sparse internal lattice structure and thin walls. This proprietary build style translates to proportionately less ash and minimized thermal expansion forces during flash firing.
Stratasys Direct utilizes two Stereolithography materials for investment casting patterns. SC 1000P is a custom photopolymer formulation developed for low cost investment casting patterns. SC 1000P has low water absorption, and patterns built with this material are less prone to dimensional distortion. SOMOS® Element is a newer antimony-free formulation for investment casting patterns. This material is specifically used when a project calls for casting with reactive metal alloys where antimony may contaminate the cast metallurgical properties.
Stereolithography offers a new design freedom, unbound to tooling. Designs can be easily altered and gating systems can be proven out prior to tooling. SL delivers excellent pattern accuracy and repeatability, at less expense than conventional methods. These benefits translate to higher yields in the casting process and makes the piece easier to ship and more durable in-transit than a wax pattern.
