摘要：
A method for preparing a PAEK powder for use in SLS includes the steps of:
providing a raw, non-powder PAEK material, optionally comprising one or more liquid solvents;
after the providing step, heat treating the raw PAEK to evaporate at least substantially all of any liquid solvent in the raw PAEK, causing at least substantially all of the raw PAEK to be in the form of irregularly-shaped particles;
after the heat treating step, cooling the raw PAEK; and
after the cooling step, grinding the raw PAEK to form a PAEK powder.
