METROLOGICAL ANALYSIS OF THE IMPACT OF THE ARRANGEMENT OF MODELS ON THE 3D PRINTER PLATFORM ON THE DIMENSIONAL ACCURACY OF MODELS MANUFACTURED USING PHOTO-CURING TECHNOLOGY - PJM

The paper presents the results of metrological tests and measurements of dimensional accuracy of models manufactured using the photo-curing additive technology of POLYJET MATRIX - PJM. The material from which the samples were manufactured was a liquid polymer resin with the commercial name MED610, which is characterized by a high degree of biocompatibility, which increases the validity of the research in medical and dental applications. The key parameter considered was the location of digital CAD models in selected places of the virtual building platform and it influence of dimensional accuracy. The research results showed a clear impact of the arrangement of models on the building platform on the accuracy of the produced models, both in terms of external and internal diameters.
