Hybrid Additive Manufacturing for Assembly and Postprocessing Solutions

Abstract

The paper discusses hybrid additive manufacturing (HAM) technologies to produce 3D-printed metal components and their post-processing solutions. This research demonstrates how HAM can increase the design and manufacturability of a product solution. The manufacturing techniques applied in the cases are laser powder bed fusion (LPBF), with computer numeric control (CNC), metal inert gas (MIG) welding, fusion deposition modeling (FDM), and adhesives. All these examples present different requirements; therefore, we can see how versatile and productive HAM can be by offering ways to fabricate a final part. This study highlights the possibility for HAM to transform and enable alternative routes in various sectors. However, disadvantages related to advanced material compatibility, integration of these processes, and good quality remain to be addressed for a greater HAM adoption. Four case examples suggest that re-engineering, effectively choosing the correct materials, and dealing with design limitations may be necessary to maintain the quality, functionality, and efficiency of the components presented in this study.
