Abstract
The aim of this experimental research was to 3D-print a filament based on PLA plastic with a metallic powder. The filament contained approximately 80 – 90 % of copper powder. The base component of the filament is thermoplastic PLA, a polymer belonging to the group of aliphatic polyesters. Composites based on PLA and powders have different properties from traditional PLA filaments without admixtures. The created composite structure is intended for 3D printing with the FDM (Fused Deposition Modeling) technology, using rapid prototyping. The printed samples were subjected to the sintering process. The fractures of the sintered samples were SEM and EDS analyzed.
