Polymers are substances composed of macromolecules that form by linking a large number of repetitive units known as monomers. Additive manufacturing is a part of manufacturing engineering that involves creating objects by depositing materials in thin layers. In a CAD program, the desired model is designed and then printed using one of the 3D printing methods. DLP is one of the additive manufacturing technologies based on photopolymerization. During printing, the entire surface of the intended layer is illuminated by a light projector, causing it to solidify. The printing plate moves after each solidified layer, forming the model. The aim of thesis is to investigate the influence of the printing angle and curing, on the functional properties of 3D printed models made from Prima™ Creator Value STANDARD CLEAR resin. Hypotheses are that the angle of printing and curing of the sample after it has been formed affect the mechanical, chemical, and thermal properties of the material. Models of test specimens and swelling test plates were designed using a program Fusion 360 and printed on an Anycubic Photon M3 device. The printing angle was set at 0°, 45°, and 90° with respect to the printing plate, and the time spent in the 405 nm chamber for curing was 0, 5, and 15 minutes. Mechanical properties were assessed with a tensile strenght test. Chemical properties were examined through tests of swelling in water, acetone, and methanol, as well as with infrared spectroscopy. Thermal properties were investigated using differential scanning calorimetry. The results of the conducted experiments demonstrated that the printing angle and curing time influence the functional properties of the material. Subsequent curing made the samples stiffer, less tough, and exhibited lower values of elongation at break. Samples printed at a 0° angle displayed lower elongation and higher strength compared to others. Acetone and methanol, aggressive solvents, caused swelling leading to the breakdown of samples. Curing reduced the intensity of swelling. Infrared spectroscopy indicated a change in molecular structure due to curing, observed through the change of intensity of epoxy group signals. Thermal analysis by differential scanning calorimetry did not conclusively indicate an effect of the printing angle on thermal properties, while additional crosslinking slightly raised the glass transition temperature.
