Defect analysis of vacuum casting parts fabricated by fused deposition modelling technique
Integration of Additive Manufacturing and Vacuum Casting has been proven to be a successful method in producing parts for small series production. However, there are still possibilities for defects to occur during vacuum casting process. The aim of this study is to analyze the type of defects in vac...
