Sažetak
Material behavior modeling for additive manufacturing (AM) technology represents a challenge because the manufacturing process and post-processing parameters strongly influence the me-chanical properties of the part. Photoelasticity is a well-known full-field optical technique used for direct stress/strain determination and design evaluation purposes. A novel use of digital light processing (DLP), a form of vat polymerization AM technologies in photoelastic specimen pro-duction is discussed in this paper. A number of preliminary experiments were undertaken to ad-dress critical issues related to DLP process. It was concluded that the UV exposure time, de-pendent mostly on layer thickness, and orientation are the main factors affecting the mechanical properties and the accuracy of the printed samples. Pure bending test was used to determine me-chanical and photoelastic properties of a commercially available acrylic-based photopolymer, not previously reported in the literature. The rectangular beam sample used was built in vertical layer orientation and fully-cured. The estimated value of Young’s modulus was within the ex-pected range for acrylics, and the photoelastic constant obtained provides increased confidence in the investigated acrylic polymer for photoelastic stress analysis purposes, and consequently for validation of computer-based models
