The invention is suitable for use as a laser sintering powder again with the addition of small amounts of new powder or without the addition of new powder, and also suitable for reducing the amount of returned powder that has to be disposed of and which has to be discarded. A laser sintered powder is provided. The preparation can be carried out by adding a regulator, in particular an organic carboxylic acid, to a polyamide or polyamide powder having a substantially constant solution viscosity, and the laser sintering powder having the regulated polyamide can be added without adding new powder. It has been found that it can be used in a laser sintering process multiple times, or with the addition of only a small amount of new powder. [Selection diagram] None |
