3D printing & Investment Casting for waterjet propulsion

Creating precise and filigree metal parts can be a challenge. New Zealand-based HamiltonJet specializes in waterjet actuators and relies on a combination of 3D printing and investment casting for its castings. By using 3D printed PMMA patterns, HamiltonJet is able to consolidate parts and therefore simplify it’s workflows and value chains.

In this interview, we speak with Gary Martin, plant and process engineer at HamiltonJet. He shares with us his experience with 3D printed PMMA patterns, and walks us through the workflows and benefits, PMMA patterns have compared to conventional wax patterns.
