Abstract:
The invention relates to a polymer powder for use in a layer-by-layer method in which areas of each powder layer are selectively fused by introducing electromagnetic energy. Said polymer powder contains: at least one AB-type polyamide produced by polymerizing lactams comprising 10 to 12 carbon atoms in the monomer unit or polycondensing the corresponding ω-amino carboxylic acids comprising 10 to 12 carbon atoms in the monomer unit and at least one AABB-type polyamide produced by polycondensing diamines and dicarboxylic acids, each of which comprises 10 to 14 carbon atoms in the monomer units, the AB-type polyamide containing up to 20 mole % of the AABB comonomer units and the AABB-type polyamide containing up to 20 mole % of the AB monomer units. The invention also relates to a method for producing such a powder, a layer-by-layer method for producing a molded article from such a powder in which areas of each layer are selectively fused by introducing electromagnetic energy, the selectivity being obtained using masks or by applying inhibitors, absorbers or susceptors or focusing the applied energy, and molded articles produced in said manner.

Claim (Index 10):
The process of  claim 9 , comprising:\n codissolving the polyamide of the AB type and the polyamide of the AABB type under an autogenous pressure at a temperature of from 130\u00b0 C. to 180\u00b0 C.; and then lowering the temperature in one or more stages to from 90\u00b0 C. to 128\u00b0 C.
