Abstract

The invention provides a 3D printing machine which comprises a rack, a spraying head unit, a printing platform unit and a cooling unit. The spraying head unit is arranged on the rack in a sliding manner. The printing platform is arranged on the rack in a sliding manner. The spraying head unit is located above the printing platform unit. The cooling unit comprises an installation part, two sets ofair guide parts and two cooling draught fans. The installation part comprises a connecting portion and two installation portions, wherein each installation portion is provided with a ventilation channel. One end opening of each ventilation channel is an installation opening. The two installation portions are connected through the connecting portion. Two air outlets are oppositely arranged. Each set of air guide part comprises a folding bag, an air guide cylinder and a swing mechanism, wherein one end of the folding bag communicates with the corresponding air outlet, the other end of the folding bag communicates with the air guide cylinder, the swing mechanism is connected with the corresponding air guide cylinder in a driving manner, and the air guide cylinder can be driven to swing in a reciprocating manner relative to the corresponding installation part. The printing machine is stable and reliable in work and high in printing quality.

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 technology 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] During the printing process, the pri...
