Problems solved by technology

[0005] However, LCD liquid crystal displays or projectors are of a single size. When printing larger objects, LCD liquid crystal displays or projectors need corresponding sizes to generate digital images at the bottom of the resin tank, resulting in the failure of light-cured 3D printers. The size requirement is very large, and it does not use production, handling, sales, etc.
Moreover, the cost of a single component such as a large LCD liquid crystal display is also very expensive, resulting in a high cost of the light-curing 3D printer

[0031] see Figure 1 to Figure 3 The light-curing three-dimensional printer 1 includes a forming tank 5 for carrying a molding material 6, a printing platform 3 arranged above the forming tank 5, a control device 2 for controlling the vertical movement of the printing platform 3, and a light-curing device located below the forming tank 5 , the light curing device is provided with a light processing device 7 and an organic light-emitting diode (Organic Light-Emitting Diode, OLED for short) display screen 8, and the OLED display screen 8 is located between the forming groove 5 and the light processing device 7. Wherein, the printing platform 3 is made of transparent material, and the forming groove 5 is also made of transparent material. The OLED display screen 8 of this embodiment is a display screen made of organic electroluminescent diodes, equipped with self-luminous organic electroluminescent diodes, has high contrast, thin thickness, wide viewing angle, fast response speed...

[0041] As an explanation of the second embodiment of the photo-curable three-dimensional printer of the present invention, only the differences from the first embodiment of the photo-curable three-dimensional printer will be described below.

[0042] The OLED display screen has an extension part and a projection part, the extension part has an open state and a folded state, and the projection part is connected to the extension part. When the extension part is in an open state, the area of ​​the projection part becomes larger. When the extension part is in the folded state, the area of ​​the projection part becomes smaller.

[0043] The OLED display screen of the light-curing 3D printer in this embodiment can be folded. When a large object needs to be printed, the extension part of the OLED display screen in the folded state can be unfolded to realize large-format printing and realize the 3D printing of large objects by a small printer. Print. OLED displays make 3D printing b...

Abstract

The invention provides a photocuring 3D printer and a printing method thereof. The photocuring 3D printer comprises a forming tank used for bearing a forming material, a printing platform arranged above the forming tank, a control device for controlling the printing platform to move vertically and a photocuring device located below the forming tank. The photocuring device is provided with an optical treatment device and an OLED display screen. The OLED display screen is located between the forming tank and the photocuring device. The OLED display screen is provided with an extension part and aprojection part. The projection part corresponds to a bottom plate of the forming tank in position. The extension part can adjust the area of the projection part. When a large object needs to be printed, the extension part adjusts the area of the projection part to be increased, and 3D printing of the large object can be implemented through a small printer. The 3D printing effect can be better through the characteristics of the OLED display screen. The printing precision is high, and energy consumption is lower.

Description

technical field [0001] The invention relates to a rapid prototyping device and a prototyping method thereof, in particular to a three-dimensional printer based on digital light processing technology and a printing method of the 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 (DLP) is a new type of projection technology based on Digital Micromirror Device (DMD, also known as digital micro device). The digital micromirror chip is a semiconductor switch. 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...
