Optimizing Overhang Control in Additive Manufacturing for Thermal and Thermo-Fluid Applications

Explore a 55-minute webinar on optimizing overhang control in additive manufacturing using a density gradient-based method for thermal and thermo-fluid applications. Delve into the implementation of manufacturability constraints within topology optimization frameworks, focusing on processes like Laser Powdered Bed Fusion. Examine the effects of build direction, overhang angle, and constraint parameters on cost function and topologies. Gain insights into the density gradient-based method for overhang angle control, integrated into the National Research Council Canada's proprietary diffuse Topology Optimization solver. Analyze results from thermal and thermofluid cases, deriving robust guidelines for achieving optimal, manufacturable topologies. Learn about motivations, challenges, literature review, and mathematical foundations of this approach, presented by Saad Akhtar from Polytechnique Montréal at the GERAD Research Center seminar series.
