Problems solved by technology

Among them, although glass and iron sheets can print a smooth bottom surface, they have the following disadvantages: 1. Need to apply solid glue or textured paper before printing
2. After printing, you need to use a spatula to remove the model, which is easy to hurt your hands
3. It is difficult to disassemble and assemble, either it can be removed by buckle, or it cannot be removed
Although the flexible frosted hot bed sticker does not need to be coated with solid glue and textured paper, it is also easy to disassemble, but its surface printing texture is rough, and it cannot achieve the smooth effect of glass iron sheet

Abstract

The invention discloses a 3D printer. The 3D printer comprises a shell, wherein two optical shafts are symmetrically and fixedly installed in the shell, and the same printing table is installed on thetwo optical shafts in a sliding mode; a hot bed for bearing products is arranged on the printing table; a printing nozzle which faces the hot bed is arranged above the hot bed; the hot bed comprisesa contact layer and gluing layer group which is arranged in an overlapping mode up and down and is used for providing the adsorption force and of which the surface is smooth and a magnet layer which is used for providing magnetism; and the smooth surface of the contact layer is the contact surface of a model. The 3D printer has the advantages that the structure is simple, the manufacturing cost islow, the use barrier of a user is low, the effect that the surface of the hot bed can be as smooth as the surface of a glass iron sheet is achieved, the model is convenient to remove, and solid gum and masking paper do not need to be applied.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, in particular to a 3D printer. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually realized by using digital technology material printers. It is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacturing of some products. There are already parts printed using this technology . The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others. [0003] At present, the mainstream 3D printing technolog...
