| Abstract Scope |
Creating parts by laser powder bed fusion (LPBF) process can be challenging as support material is usually required for complex parts. As LPBF can only use one material, creating a dissolvable support structure has many challenges. To have a dissolvable support, a low-density structure is usually required, but this type of structure typically has cracking and high distortion because of the residual stress. By using topology optimization, the material can be minimized while still meeting the criteria for residual stress. Using a self-terminating solution, the part will retain the material while the support structure can be fully dissolved. The goal of this project is to develop a structure/design that can ensure printability while maintaining fluid flow across all the support to allow the structure to be fully dissolvable. |
