Abstract (englisch):

High-performance thermoplastics like polyetheretherketone (PEEK), with their outstanding
thermal stability, mechanical properties and chemical stability, have great potential for various structural
applications. Combining with additive manufacturing methods extends further PEEK usage,
e.g., as a mold insert material in polymer melt processing like injection molding. Mold inserts must
possess a certain mechanical stability, a low surface roughness as well as a good thermal conductivity
for the temperature control during the molding process. With this in mind, the commercially available
high-performance thermoplastic PEEK was doped with small amounts of carbon nanotubes (CNT,
6 wt%) and copper particles (10 wt%) targeting enhanced thermomechanical properties and a higher
thermal conductivity. The composites were realized by a commercial combined compounder and
filament maker for the usage in a material extrusion (MEX)-based 3D-printer following the fused filament
fabrication (FFF) principle. Commercial filaments made from PEEK and carbon fiber reinforced
PEEK were used as reference systems. The impact of the filler and the MEX printing conditions like
