CHARACTERIZATION OF NEW THERMOPLASTICS FOR ADDITIVE MANUFACTURING BY SELECTIVE LASER SINTERING

摘要

Additive manufacturing technologies like selective laser sintering offer the potential to create complex, individualized parts in series. Predominantly polyamidel2 can be used for direct part generation. This leads to restrictions for many industrial and medical applications. Thus research on further polymers plays a major role for applying additive manufacturing to serial production of individual products. Currently, great efforts are made to process new technical thermoplastics by selective laser sintering. The suitability and processing behaviour by means of melting, (isothermal) crystallization, resulting morphology and part-properties of thermoplastics like polyoxymethylene, polyethylene and polypropylene is presented and compared with commercially available powders in this paper.
