In this paper we present a prototyping method used in medical data. 3D printing technology is extremely important, especially in medical area. Using 3D printing in preoperative treatment planning seems to be a proper solution in personalized medicine, contributing to improving healthcare system quality. Medical measurements methods on living bones, with respect to their natural environment are still unknown, the basic research includes mainly the measurement of landmarks using a digital caliper, where the linear measurement is taken between the marked points. Another way is to use a coordinate measuring machine. Most often, the accuracy measurement methods are based on marking landmarks on the object, which are collected by a machine, and then performs coordinate measurements of points. In our research we focus not on individual points of the model but on the measurement of whole objects, we prepared materials, and printed the model in 3D technology in different technologies and on different devices: FDM, PJ, SLM. On the basis of our work we conclude there is no best RP technique for making medical models. Due to the criterion of model accuracy, PolyJet is one of the most suitable technologies for medical modelling. The CJP method is the most appropriate for the cost of making a model. Due to the type of material the FDM method is the most suitable for medical applications. 3D printing technologies provide physicians, engineers and scientists with the ability to create customized solutions for a variety of conditions.
