Design Optimization of Plastic Injection Tooling for Additive Manufacturing. Procedia Manufacturing, 10, 923–934. https://doi.org/10.1016/j.promfg.2017.07.082https://hdl.handle.net/1805/15235This work presents a systematic and practical finite element based design optimization approach for the injection tooling adaptive to additive manufacturing (AM) technology using stereo-lithography (SLA) and powder bed fusion (PBF). First a thermomechanical optimization of conformal cooling is implemented to obtain the optimal parameters associated with conformal cooling design. Then, a multiscale thermomechanical topology optimization is implemented to obtain a lightweight lattice injection tooling without compromising the thermal and mechanical performance. The design approach is implemented to optimize a real design mold and the final optimal design is prototyped in SLA and the manufacturability in PBF has been discussed.enAttribution-NonCommercial-NoDerivs 3.0 United Statesinjection toolingconformal cooling optimizationtopology optimizationArticle
