Processability of PEEK, a new polymer for High Temperature Laser Sintering (HT-LS) [PDF]
European Polymer Journal, 2015 Abstract Currently, the HT-LS sector is predominantly based around one commercial Poly Ether Ketone (PEK) polymer. Although the combination of polymer and process works well, a lower melting temperature polymeric material, part of the same Poly Aryl Ether Ketone (PAEK) family would be preferable in certain applications.

Glass bead filled Polyetherketone (PEK) composite by High Temperature Laser Sintering (HT-LS) [PDF]
Materials & Design, 2015 Abstract Thermal expansion behaviour and mechanical performance of high temperature laser sintered PEK (LS-PEK) and glass bead filled PEK composite (LS-GB/PEK) are reported and discussed for the first time. The laser sintered PEK and its composite show anisotropic thermal expansion properties related with their multilayer structure created by the ...

Morphology of polymeric powders in Laser Sintering (LS): From Polyamide to new PEEK powders [PDF]
European Polymer Journal, 2014 Abstract In an attempt to expand the range of engineering polymers used for laser sintering, this paper examines the morphology, flowability and interparticle interactions of two commercially available Poly (ether ether) ketone (PEEK) powders, not yet optimised for the LS process, by comparison with the LS optimised Polyamide (PA) and Polyetherketone
