Abstract: 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.

Abstract: The invention relates to a thermoplastic composition used for forming articles having both high gloss and excellent resistance to mar, scratch and/or abrasion. The composition contains very high levels of nano-sized inorganic additives, such as alumina, silica and titanium dioxide. Acrylic polymer compositions, such as Arkema's PLEXIGLAS® resins, with 5 to 25 weight percent of sized fumed silica are a preferred embodiment of the invention, especially when combined with a dye or pigment.
