People with visual impairment are excluded from experiencing the cultural heritage presented by museums in a traditional manner. To enable them to touch the museum exhibits, a set of touchable copies needs to be made. The article presents the use of latest computer graphics technologies, such as 3D scanning, postprocessing and 3D printing, in improving such an enterprise. The current state of research is discussed both in the technical and organisational aspect of preparing "tactile expositions". This is followed by a step-by-step description of preparing touchable museum objects, with a discussion of the possible use of 3D technologies to aid this task. Attention is also paid to issues connected with engineering education of students. The authors think that the problem of creating objects accessible to the blind is socially useful and will encourage students to be active in this area. Finally, a genuine museum object is described as an illustration of preparing a touchable exhibit, clearly showing the advantages of using 3D technologies to this end.
