Thermoplastic polymer powder for 3D printing with improved recyclability

A powder intended for 3D printing, based on thermoplastic polymer, wherein it contains at least 0.1% by weight of at least one thioether antioxidant relative to the total weight of powder. Also, a process for stabilizing the color of a powder based on polymer in a 3D printing process, in which at le...
