Polymer powder with blockpolyetheramide, and the use in a process and moulding produced from this polymer powder

摘要

Polymer powder (I) for use in layer working procedures, comprises at least a block polyetheramide of oligoamidedicarboxylic acid and polyetheramine, where the selective areas of the powder layer are melted by introducing electromagnetic energy. Independent claims are included for: (1) a preparation of molded articles comprising using (I) in a layer working procedure, in which selective areas of the powder layer are melted by introducing electromagnetic energy, where the selectivity is obtained by the application of susceptor, inhibitors, absorbers or masks; and (2) a molded article, obtained by using (I).
