Abstract

Described are powders for use in the production of three-dimensional structures or molded bodies by means of layered manufacturing methods, and methods for the economical production thereof. The powders have the particularity that they have a good flow behavior, on the one hand, and that they are simultaneously configured such that the molded body produced with the powder in rapid prototyping has substantially improved mechanical and/or thermal characteristics. In accordance with a particularly advantageous embodiment, the powder comprises a first fraction that is present in the form of substantially spherical powder particles and that is formed by a matrix material, and at least one further fraction in the form of strengthening and/or reinforcing fibers that are preferably embedded into the matrix material.
