Problems solved by technology

[0004] However, since the photosensitive resin of the molding material is continuously consumed during the printing process, the liquid level of the photosensitive resin in the resin tank will gradually drop. In the prior art, when the resin is consumed, the resin is replenished manually, which is a cumbersome operation. And it takes time, and when the human operation is added improperly, it is easy to cause the liquid resin to seep or flow out of the resin tank, causing pollution to the printer, which in turn affects the printing accuracy of the printer, and even causes damage to the printer

Embodiment

[0023] A DLP three-dimensional printer, comprising a housing 1, a control unit, a lifting stage 2 and a resin tank 3 are arranged in the housing 1, and a DLP projection device located below the resin tank 3, and the lifting stage is arranged in the resin tank 3, and connected to the lifting screw 22, so that it can move up and down along the lifting screw 22;

[0024] At the same time, the bottom of the housing is also provided with a control panel 6 connected to the control unit and cooling holes 8 for heat dissipation. The control panel 6 is a touch screen, through which the control panel 6 can be used to control the three-dimensional printer and observe the corresponding data.

[0025] At the same time, it also includes a raw material storage device that communicates with the control unit and is connected to the resin tank 3 through the discharge pipeline 12, and a distance measuring sensor 4 arranged above the resin tank 3. The discharge pipeline 12 is provided with an ope...

Abstract

The invention provides a DLP three-dimensional printer which comprises a shell, a control unit, a lifting objective table, a resin tank and a DLP projection device located below the resin tank, wherein the control unit, the lifting objective table and the resin tank are arranged in the shell. A raw material storage device communicating with the control unit and connected with the resin tank through a discharging pipeline, and a distance measuring sensor arranged above the resin tank are further included. An electromagnetic valve for opening and closing the pipeline is arranged on the discharging pipeline. The DLP three-dimensional printer is provided with the raw material storage device and other automatic feeding devices so that the DLP three-dimensional printer can have an automatic feeding function, manpower is liberated, and the working efficiency of the whole three-dimensional printer is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a DLP three-dimensional printer. Background technique [0002] A 3D printer is a device based on a digital model of a 3D object, using materials such as plastic, liquid photocurable resin, and powdered metal to construct a 3D object by layer-by-layer printing. [0003] Digital Light Processing technology (Digital Light Processing, referred to as DLP) is a new type of projection technology based on a digital micromirror device (Digital Micromirror Device, referred to as DMD, also known as a digital micro device). 500,000-1.3 million microlenses are integrated on the CMOS silicon substrate, 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 onto the screen through the projection mirror, when When a micromirror is in the "off" state, incident light will be reflected to the light absorber...
