The paper is focused on the possibility of creation teaching aids with using colour 3D printers. The main emphasis will be given to MCOR IRIS HD printing machine. The usage of teaching aids and models representing the real phenomenon is quite useful in many scientific spheres. Nowadays we can achieve these models in various ways from the classic machine-tools to modern 3D printers which became very popular. The technology of MCOR IRIS is one of the latest in the field of the 3D printing. The printer uses ordinary white or printed papers as its printing material. Paper sheets are glued and cut by the special knife. This technology allows the production of fully coloured and relatively cheap models. There are still several limits such as sharp edges or the duration of the building process which can destroy the results. On the other hand, the printer is easily able to build a lot of different models (including tactile maps, houses, volcanos) in comparatively good quality and short time. The paper discusses the strength and weakness of mentioned technology focusing on data accessibility and models preparation. The main benefit is an easy and accessible creation of models for the scientific researchers and exhibitions. [ABSTRACT FROM AUTHOR]
