Reproducibility of 3D printed structures

Additive manufacturing – 3D printing is increasingly applied in the development project from idea to the finished product. With additive manufacturing it is possible to create products with complex geometry from 3D CAD model in very short time, which is very difficult or even impossible to do with other manufacturing technologies. With all the advantages, from the very beginning of additive manufacturing, major drawback is the reproducibility of printed structures. Uniqueness of process results in a whole range of adverse effects on the printed product such as deviations from the expected length measures, deviations of form (roundness, cylindricity, straightness, etc.), deviations from the position (location, concentricity, symmetry, etc.), deviations from the orientation (parallel alignment, verticality, inclination angle) and the inability to achieve a uniform surface texture. Test plate processed with PolyJet Matrix, with various typical geometries for this process will be printed and dimensional measuring, deviations of shape, position and orientation of the printed structures on test plate will be conducted using conventional measurement methods and X- ray Computed Tomography.
