Metallic Surface Coating of Polymeric Parts Produced by Additive Manufacturing Process

Abstract:

Metal coating films were deposited on the surface of the pieces of non-conducting polymers, acrylonitrile butadiene styrene (ABS), high impact polystyrene (HIPS) and poly (lactic acid) (PLA). These three polymers have been used since they are the main raw materials available for fusion and deposition molding equipment. In order to achieve surface metallization by electrodeposition, it was necessary to apply a pre-treatment using the chemical polymerization technique in solution with the electroconductive polymer polypyrrole (PPy) was deposited on the specimens. A uniform layer of PPy was deposited on the surface of the specimens of the ABS and HIPS polymers, while in the specimen of the polymer PLA this layer showed uniformity faults. After this pretreatment was possible to perform copper electrodeposition, creating the metallic coatings on the ABS / PPy, HIPS / PPy and PLA / PPy surfaces. This metallic coating was uniform in all specimens except the one of the PLA polymer that was not sanded. The adhesion of the coating was evaluated by the adhesion test with tape and the quality of the appearance (absence of visual defects), the morphology, the uniformity, the thickness, the conductivity and the adhesion quality of the films were analyzed.
