With 3D printing technology research accelerating year by year and with increasing number of applications of adaptive
manufacturing in final products, engineers face the problem of having access to realiable design codes for elements
manufactured with those new technologies. By the very nature of the 3D printing technology, manufactured elements are
characterized by high degree of anisotropy of strength properties. The aim of the presented research is to establish reliable
testing protocol for assesment of anisotropy of mechanical behaviour and to create data bases of experimental results for
validation and calibration of numerical models. Besides traditional experimental techniques, new techniques based on Digtal
Image Correlation (DIC) and in house developed software are incorporated into the experimental pipeline. In the presented
research relatively, simple test cases of specimens under uniaxial tension and compression were analyzed. That allowed for
simpler correlation of results from strength testing machine, DIC analysis and simple mechanical model, as well as clearly
showed anisotropy effects. The rough surface of printed specimens turned out to be ideal for DIC measurements. The results
obtained can be used to calibrate numerical models before testing more complex cases.
