Abstract

The invention relates to a photocuring 3D printer. The photocuring 3D printer comprises a resin pond and a cooling structure; the cooling structure comprises a first refrigerator, a first pipeline anda second pipeline, one end of the first pipeline communicates with the first refrigerator, the other end of the first pipeline communicates with resin in the resin pond, one end of the second pipeline communicates with the first refrigerator, the other end of the second pipeline communicates with resin in the resin pond, and the first refrigerator, the first pipeline, the second pipeline and theresin pond form a resin circular loop. The photocuring 3D printer solves the problem that in the prior art, a cooling liquid pipeline is laid below an LCD screen, and the printing precision is affected, the printing precision is improved, and the service life of a resin pond film can be prolonged.

Description

technical field [0001] The present disclosure relates to the technical field of 3D printing, in particular, to a photocuring 3D printer. Background technique [0002] The photosensitive resin is stimulated by light to change from a fluid state to a solid state. The polymerization reaction is an exothermic reaction. The heat cannot be dissipated in a short time and accumulates at the bottom of the resin pool, which makes the temperature of the resin in the resin pool rise and distribute in steps. The closer to The bottom of the resin pool, the higher the temperature. High temperature increases the adhesion between the release film and the printed body, reducing the service life of the release film. At the same time, if the temperature is too high, the service life of the relevant electronic components in the printer will be greatly reduced. Taking the LCD light-curing 3D printer as an example, when the local temperature of the LCD screen surface exceeds 70°C, the LCD screen ...
