COMPOSITION DE POUDRE THERMOPLASTIQUE ET OBJETS TRIDIMENSIONNELS FABRIQUES PAR FRITTAGE D'UNE TELLE COMPOSITION

摘要

The present invention relates to a thermoplastic powder composition with D50 lower than 100 m, including: at least one block copolymer having a inciting temperature lower than 180° C.; 15 to 50 wt % of at least one powdery filler having Mohs hardness lower than 6 and D50 lower than 20 m; and 0.1 to 5% of a powdery flow agent with D50 lower than 20 m, relative to the total weight of the composition. The present invention relates in particular to the use of said composition in methods for agglomerating powder, layer by layer, by melting or sintering, in order to manufacture flexible three-dimensional objects.
