Problems solved by technology

Considering that in the current DLP light-curing 3D printer structure, when the printing layer and the bottom surface of the resin tank are demolded, the workbench fixing the resin tank cannot be tilted and offset, and the resin tank is rigid as a whole (the material is generally glass or acrylic), the bottom surface of the groove cannot produce a certain amount of deformation, and the printing platform needs to exert a large external force when it is lifted up against its own weight and gas and hydraulic pressure, which increases the requirements for the overall structural strength of the printer frame, and the printer frame is easily damaged. ; At the same time, the printing layer is rigidly separated from the bottom surface of the resin tank, which will also affect the demoulding effect of the printing layer. Since the photolithography 3D printer constructs the object by printing layer by layer, each printing in the whole construction process of the object Each layer needs to be demolded from the bottom of the resin tank once, so the above structure will seriously affect the final molding effect of the object, cannot improve its surface finish, and will also affect the overall service life of the 3D printer

Abstract

The invention discloses a part of a DLP (Digital Light Processing) photo-curing 3D printer and in particular relates to a worktable assembly of a DLP photo-curing 3D printer. The worktable assembly comprises a worktable and a transparent resin tank, wherein a mounting bottom frame is connected onto the worktable in parallel, the transparent resin tank is fixed on the mounting bottom frame, one side of the mounting bottom frame instantly inclines upwards when a printing layer and the bottom surface of the transparent resin tank are demoulded and the mounting bottom frame can automatically restore after the demoulding process is finished. The worktable assembly achieves the technical effect that the mounting bottom frame can incline and deviate relative to a base plate of the worktable when the DLP photocuring 3D printer works and the printing layer and the bottom surface of the transparent resin tank are demoulded, thereby saving energy and materials and improving the product printing quality of the DLP photocuring 3D printer.

Description

technical field [0001] The invention relates to a component of a DLP light-curing 3D printer, in particular to a workbench assembly of a DLP light-curing 3D printer. Background technique [0002] The working principle of DLP light-curing 3D printers: using digital light processing (DLP) technology, a projector is used to cure liquid photosensitive resin layer by layer. It is capable of printing objects with very fine resolution, surpassing typical fused filament fabrication (FFF) 3D printers. [0003] DLP light curing 3D printer mainly consists of two parts: software and hardware. The above hardware part mainly includes the printer frame, projector, printing platform, workbench and resin tank. In the specific work, the resin tank is fixed on the workbench, and the two together constitute the workbench components of the DLP light-curing 3D printer, the printing platform The continuous layer structure sinks into the resin tank. The resin tank is basically a cylinder filled w...
