Abstract
A 3D printing apparatus includes a synthetic resin bath for a photosensitive synthetic resin and a lifting apparatus. The photosensitive synthetic resin at the lifting apparatus is polymerizable by light of a specified wavelength. The 3D printing apparatus further includes a carrier medium having a coupling-in region and a coupling-out region, and an illumination apparatus to emit light onto the coupling-in region. The coupling-in region includes a coupling-in deflection structure to couple light of the specified wavelength incident on the coupling-in deflection structure from the illumination apparatus, into the carrier medium in a direction of the coupling-out region, and the coupling-out region is disposed below the synthetic resin bath and includes a coupling-out deflection structure configured to couple the light of the specified wavelength that is incident on the coupling-out deflection structure, as an exposure pattern, out of the carrier medium onto the photosensitive synthetic resin.
