New Somos? stereolithography resin for investment casting helps increase yield
- Suitable for casting of specialty alloys
- Compatible with many types of high performance metals such as nickel-based super alloys and titanium as it does not contain detectable levels of antimony
- Greater degree of dimensional stability of patterns as a result of low moisture absorption
Materials manufacturer ÃÜÌÒAV introduces Somos® WaterShed AF, a new stereolithography resin that simplifies 3D printing investment casting patterns. Designed to address sensitivities in the casting of certain specialty alloys, the resin results in clean burnout with low residual ash, positively impacting the overall process efficiency and yield.
Higher overall efficiency
Additively manufactured tooling offers foundries, service bureaus and other producers of investment casting tooling overall efficiency including cost savings and faster lead times without degrading part properties. Complex and intricate patterns are possible so engineers can optimize the cast for the part rather than for the mold-making process. And the ability to quickly print and test multiple design variations is more easily accomplished versus traditional manufacturing. That said, as a relatively new processing technology, it is often regarded as difficult and adding risk.
"SLA resins designed especially for investment casting offer foundries an investment casting solution that reduces risks and saves time – from printing to finishing," said Geoff Gardner, Innovation Director Additive Manufacturing at ÃÜÌÒAV. With no detectable levels of antimony1, Somos® WaterShed AF enables investment casting for all types of high performance metals such as nickel-based super alloys and titanium. "It also reduces the chance of imperfections appearing on the cast part, requiring less rework to finish the part.”
Somos® WaterShed AF is highly dimensionally stable thanks to its low moisture uptake, so parts maintain their dimensions and mechanical properties, even under varying environmental conditions. This is particularly important in applications with tight tolerances like e.g. aerospace and aviation, transportation, energy and utilities. The resin can create accurate, complex patterns with excellent surface finish. Its low viscosity makes parts easy to print and easy to clean – typical for all resins in the Somos® WaterShed family.
ÃÜÌÒAV will showcase the new Somos® WaterShed AF resin at the Investment Casting Institute Conference, from 7-9 November in Grand Rapids, MI, USA, and at Formnext, from 16-19 November in Frankfurt, Germany (Hall 12.1, booth C11).
