Abstract
This work aimed to obtain properties of the polymer surface based on polylactic acid (PLA) used in the manufacture of facial protectors (face shields) made by additive manufacturing (3D printing), in the uncoated and coated situation with an inorganic sealant based on copper, which is expected to provide bactericidal activity. The methodology included the manufacture of PLA polymeric plates through additive manufacturing, which were coated with a copper sulfate-based sealant. Techniques of visual inspection, optical microscopy (OM), scanning electron microscopy (SEM), semi-quantitative chemical analysis by energy-dispersive spectroscopy (EDS), surface roughness measurements and digital image analysis and processing (DIP) were used. The results showed that it was possible to reach 17% surface coverage and that the copper sulfate was encapsulated by the varnish, which was used as a matrix for the sealant.
