1. carry out by electromagnetic radiation the method that selective sintering manufactures three-dimensional body by the polymer of powder type, the method comprises the following steps:

  • I () is selected to comprise melt viscosity 0.2-1.0kN*s/m 2poly aryl ether ketone polymer or the powder of poly (aryl ether ketone) copolymer;

    (ii) make the powder comprising poly aryl ether ketone polymer or poly (aryl ether ketone) copolymer of step (i) carry out selective sintering by electromagnetic radiation, form described three-dimensional body;

    (iii) after described three-dimensional body completes, with the cooldown rate of 0.01-10 DEG C/min by three-dimensional body from the fusion temperature T than the polymer contained by powder or copolymer mthe temperature of low 1-50 DEG C is cooled to the glass transition temperature T of polymer contained by powder or copolymer g;

    Wherein manufactured three-dimensional body has the final degree of crystallinity of 5-45%.
