Sunken type 3D printer forming system

Abstract

The invention provides a sunken type 3D printer forming system. The sunken type 3D printer forming system is characterized by comprising a base, wherein a material cylinder which is used for accommodating printing materials is arranged on the base; an upper fixed base is arranged at the upper end of the material cylinder; a forming platform which can be moved up and down is arranged in the material cylinder; an exposure module which can be moved up and down is arranged above the material cylinder; a device A for reducing the tensile force of the surface of the printing material is arranged between the exposure module and the forming platform; the exposure module is provided with a light source, and is positioned above the material cylinder and does not directly contact with the material cylinder; the printing material is cured after being irradiated by light, the forming platform is moved downwards, and a layer of printing is finished. During printing, through a sunken structure, the light source of the exposure module is vertically irradiated onto a liquid-state photosensitive resin material in a short distance, so that the exposure time is shorter, the printing speed is high, the strength of printed workpieces is higher, and the device A is used for reducing the tensile force of the surface of the printing material, so that the printing accuracy is higher, and the printed workpiece is more attractive.

Description

【Technical field】

[0001] The invention relates to the field of 3D printers, in particular to a sinking 3D printer forming system. 【Background technique】

[0002] With the progress of science and technology and the development of economy, 3D printing technology and 3D printers are more and more widely used in our life.

[0003] 3D printing technology is also called additive manufacturing, which is quite different from traditional processing methods. It is a manufacturing technology realized on the basis of discrete and accumulation principles. This technology uses a computer to form a part model, and then cuts it into thin slices with a set layer thickness through software calculations, and stacks three-dimensional parts regularly in the 3D printer equipment.

[0004] Most of the 3D printers at the present stage adopt an upward-sinking structure, and the light source is set under the forming platform. The distance between the light source and the printing material is relativ...
