Additive manufacturing (AM) are taking an increasingly important place in today's production of finished usable components. In particular, Fused Deposition Modeling (FDM) are most used technology in the field of polymer component manufacturing. One of the characteristics that must be treated with special attention in order for the manufactured element to be usable is the surface quality of manufactured parts. In the case of FDM technology, one of the main parameters that has a significant impact on the quality of the processed surface is the angle of inclination during manufacturing. The inclination of the surface relative to the build plate of the additive manufacturing device is defined by the orientation of the model and the definition of the manufacturing direction. This paper examines the influence of the incline angle on the surface quality of components manufactured from Polylactic Acid (PLA) material using FDM technology.
