Abstract
A filament material and a method for producing the same is disclosed. For example, the filament material includes a polymer resin that is compatible with an extrusion based printing process and a marking additive that allows selective portions of the filament material to change color when exposed to a light, wherein the marking additive is added to approximately 0.01 to 25.00 weight percent (wt %).
Claims18
A method for producing a filament material for an extrusion based printer, comprising:
- providing a polymer resin that is compatible with the extrusion based printer;
- mixing into the polymer resin a marking additive that is color changeable in response to certain light wavelengths to form the filament material such that when a surface of the filament material is exposed to the certain light wavelengths, a mark on the surface of the filament material is formed due to a change in color of the marking additive;
- and
- mixing into the polymer resin and the marking additive a developer component comprising at least one of:
- a polyphenol, a melamine resin, or a polysaccharide.

A method for marking a three-dimensional (3D) printed object that is printed with a filament material with a marking additive, comprising:
- receiving, by a processor, instructions to print the 3D printed object;
- controlling, by the processor, an extrusion based printer to print the 3D printed object in accordance with the instructions, wherein the 3D printed object is printed with the filament material with the marking additive, wherein the filament material with the marking additive comprises a polymer resin and 0.01 to 25.00 weight percent (wt %) of the marking additive that is color changeable in response to certain light wavelengths, wherein the filament material further comprises a support material comprising at least one of:
- silica, alumina, titanium oxide, mica, kaolin, zinc oxide, calcium carbonate, talc, or ceramic;
- receiving, by the processor, marking instructions associated with a marking for the 3D printed object;
- and
- controlling, by the processor, a laser to expose portions of a surface of the 3D printed object in accordance with the marking instructions to change a color of the portions of the surface of 3D printed object to write the marking on the surface of the 3D printed object.
