Abstract
A three-dimensional (3D) printed object is described. The 3D printed object comprises a polymer. A surface of the 3D printed object comprises the polymer 5 and a UV absorbing colorant. The surface has a surface area roughness Sa (arithmetical mean height) of ≤5.0 μm. A method for preparing a three dimensional (3D) printed object having a smooth surface is also described.
Claims18
A three-dimensional (3D) printed object comprising a 3D printed body consisting of fused polymer particles, wherein the 3D printed body has an outer surface coated with a UV absorbing colorant that consists of a metal oxide, wherein the 3D printed object has a surface area roughness Sa (arithmetical mean height) of ≤5.0 μm.
A method for manufacturing a three dimensional (3D) printed object having a smooth surface, the method comprising:
- forming an initial 3D printed object including a body having a surface, wherein the body consists of fused polymer particles;
- coating the surface of the body with a UV absorbing colorant that consists of a metal oxide;
- irradiating the surface of the body with UV light to melt the fused polymer particles of the coated surface;
- and
- solidifying the melted polymer particles to achieve a surface area roughness Sa (arithmetical mean height) of the 3D printed object of ≤5.0 μm.
