Polymer additive manufacturing technologies are booming, in particular thanks to the emergence of more affordable machines and strong media coverage. However, these technologies remain limited to the manufacture of non-functional or poorly stressed parts due to their low mechanical properties compared to injected parts.

 

The growing interest in these technologies is explained by the many advantages they offer. However, the relative youth of this family of processes still creates barriers to its deployment in the industry.

 

The project aims to evaluate two additive manufacturing technologies, laser sintering of powder material (LS) and material extrusion (FFF, FDM), applied to high temperature polymers out of the groups of PAEKs, especially PEEK (for FFF) and PEKK (for LS and FFF) with and without carbon fiber reinforcement.
