rapid prototype modeling powder and process for prototype production

摘要

Powder for rapid modeling of prototypes and process for the production of same. The present invention relates to powders for use in the production of three-dimensional molded structures or bodies by means of layer forming processes, as well as processes for the economical production thereof. The powders have the peculiarity that, on the one hand, they have good creep behavior and, at the same time, they are constituted in such a way that the molded bodies produced with the powder in rapid prototyping have significantly improved mechanical and / or thermal characteristics. According to a particularly advantageous embodiment, the powder has a first part, which is in the form of substantially spherical powder particles and is formed of a matrix material, and at least one other part in the form of stiffening and / or reinforcing fibers. which are preferably embedded in the matrix material.
