Support slimming for single material based additive manufacturing
In layer-based additive manufacturing (AM), supporting structures need to be inserted to support the overhanging regions. The adding of supporting structures slows down the speed of fabrication and introduces artifacts onto the finished surface. We present an orientation-driven shape optimizer to slim down the supporting structures used in single material-based AM. The optimizer can be employed...
متن کاملThermal Stresses Associated with Part Overhang Geometry in Electron Beam Additive Manufacturing: Process Parameter Effects
For powder-bed electron beam additive manufacturing (EBAM), support structures are required when fabricating an overhang to prevent defects such as curling, which is due to the complex thermomechanical process in EBAM. In this study, finite element modeling is developed to simulate the thermomechanical process in EBAM in building overhang part. Thermomechanical characteristics such as thermal g...
متن کاملEvaluation of a digitised splinting approach with multiple-material functionality using Additive Manufacturing technologies
The design and fabrication of custom-made wrist immobilisation splints can be a laborious process. In addition, patient adherence in terms of wear duration and frequency may be affected by a range of contributing factors including poor aesthetics, hygiene issues and fit. This paper suggests the use of additive manufacturing (AM) in a bid to resolve factors affecting adherence and improve the ef...
متن کاملNew possibilities using additive manufacturing with materials that are difficult to process and with complex structures
Additive manufacturing (or 3D printing) opens the possibility of creating new designs and manufacturing objects with new materials rapidly and economically. Particularly for use with polymers and polymer composites, simple printers can make high quality products, and these can be produced easily in offices, schools and in workshops and laboratories. This technology has opened a route for many t...
متن کاملContact-Free Support Structures for Part Overhangs in Powder-Bed Metal Additive Manufacturing
This study investigates the feasibility of a novel concept, contact-free support structures, for part overhangs in powder-bed metal additive manufacturing. The intent is to develop alternative support designs that require no or little post-processing, and yet, maintain effective in minimizing overhang distortions. The idea is to build, simultaneously during part fabrications, a heat sink (calle...
