ADDITIVE MANUFACTURING AT GE RESEARCH

Steve Duclos | Chief Scientist – Additive Manufacturing, GE Research Chip Cotton | Account Executive – Government Relations, GE Research

Advanced additive technologies that enhance maintenance capabilities: • Shortening the design-to-print workflow • Lowering the cost of additive • Enabling a secure additive network

Topology Optimization & Generative Supports Build Simulation Distortion Compensation Producibility Shortening the design-to-print workflow: account for producibility & predictable disturbances

Process Variation Control & Compensation

Roadmap  Sensor capability ALSAM  Software analytics Developments  Control algorithms

Rapid qual & cert through sensor & models: Open control platform to enable multi-laser: Higher yields with advanced process control Accelerate builds & lower cost

ADVANCED BINDER UP TO UP TO 80% TECHNOLOGY, 100x CHEAPER RAW FASTER BUILD SPEED DISTORTION MANAGEMENT Compared to single laser LPBF MATERIAL FEEDSTOCK & CONTROL Compared to LPBF
