Reliable parts production: Integrated Additive Manufacturing with topology optimisation

Related Vendors

Numerical modelling experts for robust generative design, Rafinex, and digital manufacturing specialists, Module Works, have combined workpiece topology optimisation with intelligent toolpath planning in an efficient, sustainable solution for Powder-Bed-Fusion (PBF).

Rafinex topology optimisation anticipates real-life variability in material loads and properties to help engineers design resilient, reliable parts for stress-critical applications. The intelligent solution includes a full scope FEA validation to de-risk any design. Combining this with Module Works toolpath algorithms enables engineers to include manufacturability in their designs very effectively for a range of additive processes.

"Integrating toolpath algorithms in topology optimization is a tremendous benefit because manufacturing constraints included in the design phase save time and costs further down the line. Our aim is to continue delivering best-in-class design optimization across the industries. Our latest collaboration with Module Works extends our SaaS solution to important additive processes such as Powder Bed Fusion", said André Wilmes, CEO at Rafinex.

Integrated into the Rafinex solution, the Module Works software generates highly automated, collision-free toolpaths for PBF. The workflow enables users to quickly program resilient, high-performance parts for production where expert knowledge of the manufacturing process is not required. The pre-defined parameters assist engineers in optimising the workpiece geometry for the PBF process to generate a toolpath and NC code that automatically minimises material waste.

Lothar Glasmacher, Head of Additive & Process Technologies at Module Works: "We look forward to our continued cooperation with Rafinex and further development of the technology beyond PBF to include Wire Arc Additive Manufacturing (WAAM) in the midterm."

Rafinex will be presenting the new solution at the Hannover Messe, 17 - 21 April 2023 in Hannover, Germany.
