Abstract

This study investigated the production and properties of polyamide 11 matrix hollow ceramic microsphere reinforced composites. The composites were produced at 10 wt% and 20 wt% reinforcement ratios by selective laser sintering using different energy density values. The influence of the energy density values and hollow ceramic microsphere additive on the properties of the samples was determined. The ceramic microspheres provided the production of lightweight samples. Moreover, the wear behaviour of the samples improved significantly with a combined effect of the energy density and usage of ceramic-based microsphere. The wear rate was reduced to 2.75·10⁻⁴ mm³/Nm at 0.0500 J/mm² energy density and 20 wt% reinforcement ratio.
