摘要： The invention relates to a polymer powder, comprising polyamide, use thereof in a moulding method and moulded body made from said polymer powder. The moulding method involves layering methods using powder, whereby selective regions of the relevant layer are fused by introduction of electromagnetic radiation. The selectivity can be achieved by means of masking, application of inhibitors, absorbers or sensitizers, or by focussing of the input energy, without restricting the invention thereto. After cooling, the solidified regions can then be removed as a moulded body from the powder bed. The moulded bodies produced thus exhibit clear advantages in the component properties, in particular, the surface properties compared to moulded bodies made from conventional powders. A further advantage is that the improved surface properties do not negatively affect the other properties, so that the machinability remains good and the mechanical properties are also no worse than for components made from conventional polymer powder.

摘要： Two moulded parts A and B that cannot be directly welded together can be welded to each other with the aid of a film C, if the material of the first surface of the film is compatible with the material of the moulded part A and the material of the second surface of the film is compatible with the material of the moulded part B and if either the film C or a surface region that comes into contact with it adsorbs electromagnetic radiation. Welding is carried out by the first surface of the film C being brought into contact with the moulded part A and the second surface of the film C being brought into contact with the moulded part B and electromagnetic radiation being radiated in.

摘要： Process for producing ultrafine powders based on polyamides, in which polyamides having a relative solution viscosity ηrel in the range from 1.5 to 2.0, measured in 0.5% strength m-cresol solution at 25°C, are brought into contact with an alcoholic medium in the presence of inorganic particles under superatmospheric pressure and/or elevated temperature to produce an at least partial solution and the polyamide is subsequently precipitated from the at least partial solution, characterized in that a suspension of the inorganic particles suspended in the alcoholic medium is used. The resulting ultrafine polyamide powders have a specific surface area determined by the BET method in the range 5-100 m2/g, a fineness d50 of less than 70 µm; a bulk density BD in the range from 250 to 1000 g/l; and a particle content of from 0.1 to 80% by weight of inorganic particles based on the total weight of the polyamide powder. They are suitable both for coatings and for shaped parts and components having improved mechanical properties.

摘要： 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.
