3D printing technology is a simple nad quick way of making prototypes. In 3D printing technology, objects are being created by induration of multiple successive layers, cross-object. This technology is very useful not in industrial design only but in medicine, architecture, construction, art and every aspect of industry and researching also. Besides fast prototypes production it helps visualizing all kinds of ideas and facilitates communication with clients and associates. This thesis consists of theoretic and experimental parts. Theoretic part is basically introduction with 3D technology, explains rapid prototyping technologies and their use. Experimental part covers 3D printing issues which can occur while making prototypes. 3D printer used in this research is presented with it's specifications, parts and working principle. Software and their tools used will also be presented. For research purposes, 3D model is created in Solid Works software, and printed under different conditions. Based on a model of printed under various conditions, experiments determined which parameters, have influence in quality of printed 3D objects, considering specific device used for printing.
