Summary: | A polyaryletherketone PAEK polymeric material and use thereof is disclosed, the polymeric material comprising a homopolymer and/or a copolymer, suitable for use in an additive manufacturing process to make an object. The PAEK polymeric material has a shear viscosity, SV, of at least 145 Pa·s and less than 350 Pa·s, measured using capillary rheometry operating at 400° C. at a shear rate of 1000 s−1 using a circular cross-section tungsten carbide die, 0.5 mm (capillary diameter)×8 mm (capillary length). The PAEK polymeric material has an isothermal crystallinity half life, T1/2, of greater than 12 minutes at a temperature of 280° C., measured by Differential Scanning Calorimetry, DSC. |
