Disclosed is use of a polymer powder of block polyetheramide, produced by the polycondensation of oligoamide dicarboxylic acid and polyetheramine for preparing a three-dimensional molding by a layer-by-layer process where regions of the polymer powder layer are selectively melted via the introduction of electromagnetic energy, and after cooling, the regions are then solidified and can be removed in the form of a molding from the powder bed.
