Prototyping

FROM DESIGN CONCEPT TO CASTING


For R&D, part repairs, reverse engineers, low production quantities
Tech Cast can meet all of your SLA Rapid Prototype requirements

Tech Cast is a leader in the investment casting industry producing large SLA Rapid Prototypes to support a broad landscape of industries such as multi-stage pumps for oil & gas, critical shipboard applications for the military, etc. This SLA technology enables Tech Cast to direct manufacture investment castings in as little as a few weeks, and eliminate the need to invest capital money in expensive, long lead-time tooling. This SLA process provides the design engineer the necessary tools, freedom, and flexibility to develop new products/designs directly from a 3D CAD model to an end-use investment casting in a matter of weeks.
