Additive manufacturing, also known as 3D printing, is the process of joining organic, ceramic, polymer, metal and others materials. Most often used as input material are the ABS and PLA plastics. A large number of plastic products is constantly generated by industry, which beckons the idea how to manufacture these products in more environmentally friendly way. This paper deals with the possibility of producing a 3D printing fiber from a granular PLA material Ingeo 2003D with the addition of a mixture of color powder pigment and fiber from the selected PLA material with a glass powder filler. The production was carried out using the FilaFab PRO EX350 device, which is designed for fiber extrusion for 3D printing technology. The aim of the experiment was the creation of new materials in the form of fibers and their mutual comparison in tensile tests with commercially available materials intended for 3D printing.
