To be able to follow progress of technology very often in practice it is necessary to create a complex subject matter that we would not be able to create standard manufacturing technology, that is, it would be a costly and demanding job. Then their application comes with 3D printers that have been very advanced and use different printing methods and materials. It is a revolutionary technology that creates three-dimensional record. We have more and more applications in medicine, architecture, dentistry, mechanical engineering and all other fields of industry. In this final thesis are also described the processing technology and the materials used for three-dimensional printig. Within the work are included parts as well as the process of creating a functional 3D printer based on the Prusa i3 model.
