Thermwood taps extrusion expert American Kuhne for additive manufacturing system


American Kuhne (Ashaway, RI) customer Thermwood Corp. (Dale, IN), a manufacturer of CNC routers, announced a program to develop a 3D additive manufacturing system capable of making large carbon-graphite-reinforced composite thermoplastic components.

The system uses a near-net-shape approach, in which a custom-built, vertical, integrated extruder deposits or "prints" carbon graphite–filled thermoplastic material to quickly create a structure that is close to the final shape. Once it cools and hardens, it undergoes a 5-axis machining process to achieve its final net shape.
