More Information
Summary:The invention relates a resin composition containing a polymer matting agent, that improves the aesthetic appearance of an article formed by Material Extrusion 3D printing. The composition contains 30-99.9 wt % thermoplastic resin and 0.1-50 wt % of one or more spherical or near-spherical polymeric matting agents (PMAs) such as Altuglas Acryperl® beads from Arkema. Objects 3D printed from the composition have hidden layer lines (a.k.a. "build lines") and is more uniform in appearance, compared to an object printed from the same thermoplastic resin without PMAs.
