Abstract
The present invention provides a polymer composite particle material for three-dimensional printing. The polymer composite particle material is formed by embedding a carbon powder on a surface of a polymer powder. When the carbon powder is mixed with the polymer powder, a device with a shear force is used for stirring. Heating is performed during the stirring, such that melting occurs at the surface of the polymer powder. The carbon powder is embedded on the surface of the polymer powder to form a shell-core structure powder, and at the same time, the carbon powder is uniformly coated. The preparation method is simple and no additional dispersant and binder are needed. Besides the carbon powder will not easily separate from the polymer powder. At the same time, the agglomerated carbon powder can be dispersed by rubbing and evenly dispersed around the polymer powder to reduce a laser reflectivity.
