3D printing as an alternative to conventional manufacturing methods, and its advantages in design freedom, customization options and ease of use, experienced a rise in popularity in the last decade. With fused filament fabrication (FFF) as one of the most commonly used methods and polylactic acid (PLA) as a frequently used material option, new innovations and opportunities in this sector are not uncommon.
The use of filler materials to increase the properties of the final product or lower the impact on the environment has been the subject of several studies. Two different kinds of wood based filament with a diameter of 1.75 mm were produced in the course of this thesis. Filament with a wood content of 5% for each pine and spruce wood was extruded and tested with a 3D printer. The two different wood types used showed no significant differences in their pre-processing or influences on the outcome. The inclusion of recycled PLA further emphasizes the benefits of a circular economy in 3D printing.
The wood material usable for the selected extrusion method only amounted to a fraction of the initial residue material, optimal parameters for the filament making process were found for the single extrusion, but not for the double extrusion experiments. The 3D printing tests were successful and led to satisfying results.
The acquired findings provide a solid foundation for future projects at the Lapland University of Applied Sciences.
