Integrated Additive Manufacturing with Topology Optimization

2023年04月12日

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

Rafinex's topology optimization anticipates material load variability and includes FEA validation, while ModuleWorks' toolpath algorithms generate collision-free paths for PBF production. The solution saves time, cost, and material waste while enhancing efficiency, quality, and sustainability in additive manufacturing. Presented at Hannover Messe 2023, the collaboration between Rafinex and ModuleWorks extends to Wire Arc Additive Manufacturing (WAAM).

Rafinex topology optimization 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 ModuleWorks 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 ModuleWorks 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 ModuleWorks 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.

"This is an excellent example of how different technologies can be effectively combined to enhance the efficiency, quality and sustainability of additive manufacturing. 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 is presenting the new solution at the Hannover Messe, 17 – 21 April 2023 in Hannover Germany. The solution is on show at the Rafinex Stand, Hall 2, Stand B40.
