摘要： The invention relates to particles for producing a three-dimensional object by using layer-building methods (powder-based generative rapid prototyping methods), to methods for producing a three-dimensional object therefrom, and to an object that can be produced by using the particles or the methods. The aim of the invention is to improve the precision of production methods of this type by preventing the tendency of the particles used to agglomerate. To this end, a surfactant layer is applied, whereby the nonpolar groups of the surfactants are oriented toward the particle surface thus forming a hydrophobic surface having a low tendency to agglomerate.

摘要： In the rapid prototyping method of selective laser sintering, temperature gradients occur inside and between individual layers, leading to component deformation which is intolerable at least for high-quality components. The aim of the invention is to provide a method for selective laser sintering, whereby the temperature inside the built-up particle cake is as homogeneous as possible. To this end, particles containing at least one material having a maximum softening temperature of approximately 70 C are used.
