Fracture toughness in additive manufacturing by selective laser sintering: an overview
This paper presents manufacturing, testing, and computing steps for determining the fracture toughness property of polyamide PA 2200 processed by laser sintering using different process parameters. The design of the samples was conducted according to ASTM D5045-99 and ASTM D5528-01, and the fracture tests consist of four-point bending in symmetric and asymmetric configuration and double cantilever beam test. The process parameters selected as variables were in-plane orientation, spatial orientation, energy density of the process, and induced structural defects. The results provide an extended view regarding the variation of fracture properties when the manufacturing conditions in laser sintering are changed.
