Fluoropolymer powder suitable for rapid prototyping by laser sintering

摘要

The present invention relates to compositions based on fluidity-improved thermoplastic fluoropolymer powders that are particularly suitable for producing parts by 3D laser sintering, especially polyvinylidene fluoride (PVDF) -based compositions. The present invention also relates to a method of weakly agglomerating a powder layer by layer by melting or sintering using this composition. Finally, the present invention relates to a three-dimensional article obtained by carrying out this method.
