| Abstract Scope |
The surface of laser-based powder bed fusion of polymer parts (PBF-LB/P) is known for its rough texture and external appearance, whereby the surface roughness has a significant influence on the mechanical properties. Chemical smoothing with solvents is a well-known method for influencing the surface texture of PBF-LB/P components. Due to the further development and industrialization of the process, the post-processing method is becoming increasingly attractive for the use in the automotive industry. Chemical smoothing reduces the surface roughness and seals the surface, which leads to a change in the functional properties. Due to the significant increase in elongation at break at a near constant tensile strength after smoothing, this post-processing method has the potential to expand the range of applications for PBF-LB/P parts in the automotive industry. This paper is investigating the influence of the chemical smoothing process on the mechanical properties and surface roughness of polyamide 12 (PA12) parts. |
