The laser-sintering process has, beside all the advantages like a high productivity and a great design freedom, significant disadvantages with the low material variety and material ageing. A major proportion of all LS components are still made of PA12 and PA11. High performance materials e.g. PA6, PPS, PEKK, etc. are appearing increasingly on the market but they cannot be processed on standard LS systems due to the higher processing temperature. High temperature systems, on the other hand, are very cost-intensive. Additionally, the surrounding and unused powder material ages due to high process temperatures, resulting in not fully reuseable material which is not very sustainable and leads to increased costs.
