1. A 3D printer comprising:
a resin vat configured to contain liquid photopolymer resin for generating a solid component;
a component carrier configured to pull out the component layer by layer from the resin vat;
a transport box configured to deposit the component carrier, the transport box being manually placeable or fixable at a designated position outside the resin vat;
a transport device configured to take the component carrier out of the transport box and transport it into the resin vat, and to move the component carrier downwardly, upwardly and/or sideways in the resin vat,
wherein the transport device has a vertical translatory axis and a horizontal translatory axis, each of which is driven independently by a motor,
wherein the transport device has a locking device for detachable attachment to the component carrier,
wherein the locking device, during a downward movement along the vertical translatory axis, reaches, by the drive of the respective motor, a specific position at which a stop located on the vertical translatory axis sets a coupling element in motion, wherein a spring-loaded locking pin arranged in connection with the coupling element is immersed by the motion into a bayonet opening of the component carrier, and
wherein the immersed locking pin can be moved via the horizontal translatory axis into a locking position or unlocking position in the bayonet opening.
