7 DESIGN FOR ADDITIVE MANUFACTURING, CLOSING THE GAP Design to print workflow CAD Model Model Preparation e.g. define the interior Tray placement Printability Checking e.g. thin walls Slicing 3D Printer CAD Domain Goal: To bring the knowledge of Additive Manufacturing capabilities early into the design process 7

8 CREO ADDITIVE MANUFACTURING, CLOSING THE GAP Creo s value proposition is centered in closing the gap between CAD and the 3D Printer Print what you design Slicing CAD Model Model Preparation e.g. define the interior Tray placement Printability Checking e.g. thin walls 3D Printer CAD Domain CAD Domain Goal: To bring the knowledge of Additive Manufacturing capabilities early into the design process 8

9 DESIGNING FOR ADDITIVE MANUFACTURING Light weight designs without compromising stress and displacement requirements Integrated design-analysis process Simulate using additive manufacturing material properties Design to self-supporting geometries, or minimize support structures Beast (2010), Museum of Science, Boston. Neri Oxman Simplify assemblies Part consolidation, more functions in each part Biomimetic s 9

21 Creo Simulate and BMX can drive the lattice definition ANALYSIS RESULTS IDEALIZED ELEMENTS FULL GEOMETRY The lattice feature can be analyzed and optimized using Creo simulate The lattice feature parameters are exposed to be used along BMX experiments 21

22 Lattices analysis and optimization ANALYSIS RESULTS IDEALIZED ELEMENTS FULL GEOMETRY Idealized elements Automatic conversion of the lattice into beams, masses and shells. Faster results, lightweight geometry transfer to Creo Simulate 22

23 Lattices analysis and optimization ANALYSIS RESULTS IDEALIZED ELEMENTS FULL GEOMETRY Fine control over where to apply loads and constraints into the Lattice feature Each beam end-point have a datum point assigned on the open side of the lattice Those datum points can be used to define the load and constraints 23

24 Lattices analysis and optimization ANALYSIS RESULTS IDEALIZED ELEMENTS FULL GEOMETRY Full geometry Use the mesher capabilites of Creo Simulate More refined model, ideal for the final optimization cycle 24
