3D Printing Corporation, K.K. (3DPC), based in Japan, helps manufacturers develop alternative supply chains by providing a one-stop shop for strategic 3D printing services. Inspired to secure supply chains and prepare manufacturers for unexpected disruptions, 3DPC equips manufacturers with additive manufacturing (AM) parts and services to optimize and digitalize their workflows. 3DPC works with various industries and markets, from toy companies to space stations
3DPC works with a wide range of materials, including resins, metals, and composites. Predicting deformation is essential in AM to build parts successfully, keep costs down, and avoid mass printing errors. 3DPC uses Ansys’ multiphysics simulation tools to analyze and predict thermal deformation in advance and modify parameters. It is also important to balance the strength and weight
of parts. Clients seek strong parts, but also require them to be lightweight. 3DPC approaches this using a fused deposition modeling (FDM) method and integrates Ansys’ tools to optimize the process and achieve better results.
To improve the strength and weight of existing parts, 3DPC enhances the FDM method by using Ansys Mechanical and applied topology optimization to reduce part weight while maintaining strength. The team evaluates strength considering the anisotropy of the FDM method and applies this to the topology-optimized model. In one example using this approach, 3DPC successfully reduced weight by 20% without reducing strength. The team accomplished this using Ansys’ simulation capabilities to repeatedly change settings and parameters such as boundary conditions. For thermal analyses, 3DPC integrates Ansys Fluent to evaluate heat exchange efficiency and Ansys Additive Suite to predict thermal deformation using a powder bed fusion (PBF) method. Additionally, 3DPC evaluates the shock absorption performance of elastomer materials using Ansys LS-DYnA and analyzes mesh data with Ansys Discovery.
