Thermoplastic polymer powder for 3D printing with improved recyclability

摘要

The present invention relates to a powder for 3D printing, based on a thermoplastic polymer, characterized in that it contains at least 0.1% by weight of at least one thioether antioxidant, based on the total weight of said powder. The present invention also relates to a method of stabilizing the color of a powder based on a polymer in a 3D printing process, wherein at least 0.1% by weight of at least one thioether antioxidant is incorporated, based on the total weight of the powder.
