Abstract (en)
[origin: WO2019069032A1] The present invention concerns a reinforced thermoplastic powder composition, comprising: - at least one polyamide powder with D50 less than 100 mm, - 5 to 70% by weight of at least one glass fibre: - with l50 in the range from 50 to 200 mm, - lmax less than 450 mm, - d50 in the range from 4 to 40 mm, - form factor F: l50/d50 between 5 and 15, and - 0.05 to 5% of a powder flow agent with D50 less than 20 μm; compared with the total weight of the composition. The present invention concerns, in particular, the use of said composition in 3D printing methods for producing reinforced three-dimensional objects.
