Abstract Scope |
Parts fabricated from a functionally graded material (FGM) show specifically adjusted gradual changes in properties and functions along single or multiple spatial directions due to changes of composition and/or microstructure. The additive manufacturing (AM) process of High Speed Sintering (HSS) has vast potential to manufacture such FGM parts. Within the HSS process, the selective energy input into the polymer powder occurs by a sinterlamp and a radiation absorbing material (RAM). The selective adjustment of the amount of RAM controls the energy input and allows thus to adjust the microstructure and therefore the mechanical properties of the parts. This contribution describes the manufacturing process of FGM parts in HSS and the realizable propertie changes in detail for the first time. This is done by parts made of thermoplastic polyurethane (TPU) with continuous and discontinuous mechanical property changes, which are produced under variations of the relevant process parameters. |
