Selektives Lasersintern von teilkristallinen Thermoplasten

Abstract

As a flexible manufacturing for lot sizes of 1-1000 components gains
more interest in many branches of trade, technologies such as selective
laser sintering (SLS) become more interesting. Nevertheless should the
properties of materials used in series manufacturing be achievable.
Mainly polyamide 12 can be used for direct part generation. This leads
to restrictions for many applications. Thus research on other types of
polymers plays a major role in applying additive manufacturing in the
serial production of individual products. In this paper, the suitability
and processing behavior with respect of melting, (isothermal)
crystallization, morphology resulting and part properties of new
thermoplastics is presented and compared to commercially available
powders. By using thermoanalytical methods, comprehensive process
simulation can be carried out.
