Abstract
We propose an optimization framework for a support removal process. Support removal is an issue among increasing users of fused deposition modeling (FDM). Many users have to use tools to eliminate support structures from 3D-objects. Furthermore, while removing support, the 3D-object tends to break when too much stress is applied. Prior to building a 3D-object, our algorithm provides the optimal orientation that minimizes the amount of support structures using a convex-hull algorithm. Also by providing a deformable support structure that detaches better when the same force is applied, we aim to facilitate the support removal process for FDM users. We have compared our support structure generation algorithm with support structures from existing software using a materials tester, INSTRON 5900R. We also compared the time required to remove the support structure.
