Abstract
The invention relates to a composition based on a thermoplastic fluoropolymer powder, in particular on polyvinylidene fluoride (PVDF) with improved flowability, particularly suitable for manufacturing parts by 3D laser sintering. The invention also relates to a method for agglomerating powder layer by layer, by melting or sintering using said composition. The invention finally relates to a three-dimensional article obtained by implementing said method.
