Abstract
A PEKK polymer powder, having a d-value less than 150 μm, wherein the PEKK polymer has a Td(1%) of at least 500° C., as measured by thermal gravimetric analysis according to ASTM D3850, heating from 30° C. to 800° C. under nitrogen using a heating rate of 10° C./min. A method for producing a PEKK powder for the use in a method for manufacturing a 3D object, in which the PEKK has a Td(1%) of at least 500° C., as measured by thermal gravimetric analysis according to ASTM D3850, heating from 30° C. to 800° C. under nitrogen using a heating rate of 10° C./min, and the powder has been manufactured by grinding from a coarser powder and has a d-value less than 150 μm, as measured by laser scattering in isopropanol.
