Problems solved by technology

[0006] However, after the existing photocurable 3D printer completes the molding of the 3D object, the surface of the 3D object often has a lot of photosensitive resin liquid attached to it. These residual liquids need to be cleaned later, which not only easily causes environmental pollution, but also wastes resources, increasing the manufacturing cost of 3D objects

Abstract

The invention discloses a photocuring three-dimensional printer and a printing method thereof. The photocuring three-dimensional printer comprises a containing groove, a curing light source, a printing platform, a moving assembly and a vibrating assembly. After the printing of a three-dimensional object is complete, the three-dimensional object on the printing platform is vibrated by the vibratingassembly, so that liquid photosensitive resin on the three-dimensional object is shaken off, consequently, environmental pollution caused by subsequent treatment is prevented, and the material can berecovered as well, so that manufacturing cost can be reduced. A first electromagnetic attraction unit and a second electromagnetic attraction unit cooperate with each other to respectively carry outattraction or separation on the printing platform at different time, the structural arrangement is reasonable, and the objective of recovering the liquid photosensitive resin remaining on the surfaceof a finished three-dimensional object is achieved.

Description

technical field [0001] The technical field of the present invention is the field of three-dimensional molding, and in particular relates to a photocuring three-dimensional printing device and a printing method thereof. Background technique [0002] 3D printing is also called additive manufacturing or layered modeling. It uses digital models to process physical objects. In the process of molding, materials are added layer by layer to form three-dimensional objects. [0003] Digital Light Processing (DLP for short) is a new type of projection technology based on a digital micromirror device (DMD for short, also known as a digital micro device). The digital micromirror chip is a semiconductor switch. 500,000-1,300,000 microlenses are integrated on the silicon substrate, and each microlens represents a pixel. When a microlens is in the "on" state, the incident light will be reflected and the image will be projected to the screen through the projection mirror Above, when a micro...
