Sažetak
New products are functionally and geometrically more and more complex, and the time for their production should be as short as possible. Leading time to launch the product on market is the key success factor of any product. Therefore, one of the most important goals of contemporary production is to shorten the time from arise the idea of the product up to its final realization (production), i.e. to rise the production efficiency. One of the possible answers to emerging demands on product development is accepting and systematic development of Rapid Manufacturing (RM) technologies inside of the Rapid Product Development (RPD) concept. Such approach is aiming to speed up product development process, i.e. to minimize idea-to-product marketing time. Rapid production can be achieved by adopting of Rapid Prototyping (RP) and Rapid Tooling (RT) techniques. These techniques make the manufacturing of complex products possible, directly from the computer data in very short time by highly automated processes. However, one of the serious disadvantages of the rapid prototyping technique is the limited number of the used materials. Properties of available prototyping materials differ substantially from materials applied in mass production. Therefore, it is essential to test experimentally prototyping materials applied in everyday engineering practice. Aiming this we have chosen two simple parts (one standard dumbbell tensile test specimen and one standard three points bending test plate specimen) to be produced by using two different RP techniques and by using some various standard RP materials. Rapid prototyping techniques we have been used were 3D printing (ZPrint 310 prototyper) and hybrid 3D printing/stereolitography (Eden 330 prototyper). The main technical characteristics of these two technologies have been also compared aiming to find their optimum applicability in some technical and medical applications. Dimensional stability, surface roughness and mechanical properties of the specimens have been tested. All experimentally obtained material properties have been analyzed and compared with those given by the producers of correspondent RP materials.
