Analysis of the Materials Used in Some Rapid Prototyping Technologies, from the Point of View of Microhardness and Surface Quality

Abstract

The paper presents a comparative study, from the point of view of microhardness and surface quality, of samples made from materials used in rapid prototyping technologies, namely photopolymer resin and PLA. Microhardness determinations were made for both materials, with Micro-Vickers HDT-VS1D INSIZE digital automatic hardness tester, and the surface of the samples was analysed, from a qualitative point of view, with the optical microscope, OLYMPUS BX51M.
