Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing equipment, and in particular to a leveling device for a light-curing 3D printer. Background Art

[0002] A photocuring 3D printer is an advanced manufacturing tool that uses photocuring technology to solidify liquid photosensitive resin layer by layer to build three-dimensional objects. This printing technology has been widely used in various fields, including medicine, design, manufacturing, etc.

[0003] In the prior art, for example, the utility model disclosed in China Publication No. CN211807890U discloses a light-curing 3D printer comprising a workbench; a material trough mounted on the workbench and configured to provide a resin solution for printing; a locking mechanism mounted on the workbench and configured to lock the material trough to the workbench; the locking mechanism comprising at least one pair of locking assemblies, one pair of locking assemblies being arranged on opposite sides of the material trough, each locking assembly comprising a base, a locking tongue, and a power component. The material trough is provided with locking grooves on opposite side edges, the base is fixedly mounted on the workbench, the base is provided with a locking hole opposite to the locking groove, the locking tongue is movably disposed in the locking hole, and the power component is configured to drive the locking tongue to extend from the locking hole and engage in the locking groove, or to engage out of the locking groove and retract into the locking hole. This allows the material trough to be quickly locked and fixed to the workbench, making assembly and disassembly more convenient. Furthermore, the use of a locking structure instead of a traditional threaded fastening structure provides a better fastening effect and can effectively solve the problem of the material trough becoming loose.

[0004] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that there is a lack of a structure for leveling the molding plate on the horizontal plane, which may easily lead to some parts of the printed object being unable to be accurately positioned or deformed, making it impossible for the device to ensure that the printed parts have accurate size and surface quality. There is a lack of a structure for transporting the liquid photosensitive resin raw material stored in the storage box to the material trough and transporting the liquid photosensitive resin raw material in the material trough to the storage box for storage after printing is completed, which may easily lead to the liquid photosensitive resin raw material remaining in the material trough for too long for photosensitive molding, resulting in waste of raw materials.
