  • Comparison of stereolithography in two modes of illumination with DLP technology [Elektronski vir]
    Zupan, Andraž, 1988- ...
    The following paper focuses on the field of additive technology, called stereolithography. Specifically it focuses on the use of DLP technology in illuminating a medium. The medium is a photopolymer ... or resin, which hardens when exposed to a specific wavelength of light. The technology is used to generate 3D object . We used a non-commercial 3D printer to study two methods of illuminating the photopolymer using the DLP technology. The first method concentrates on the illumination of the bottom of the vat called constrained- surface method, the second one is called free-surface method and the illumination takes place on the surface of the photopolymer. Both times, photopolymerization takes place on the exposed section. We compared both methods of illumination based on the measurements of the test products. We concluded that products created by illuminating the bottom of the vat are both dimensionally and visually superior.
