abstract |
The invention relates to a composition for constructing a three-dimensional article layer by layer, by sintering of the composition caused by electromagnetic radiation, the composition comprising a semi-crystalline thermoplastic polymer powder and at least one wax, the wax having a melting point greater than the crystallisation temperature of the semi-crystalline thermoplastic polymer, the composition further optionally comprising a flow agent. The invention also relates to a method for preparing the composition and its use for constructing a three-dimensional article layer by layer. |
