Description

Technical Field

[0001] The invention belongs to the technical field of 3D printers, and in particular relates to a rapid freezing device for a graphene 3D printer. Background Art

[0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax materials, powdered metal or plastic and other adhesive materials to print layers of adhesive materials to make three-dimensional objects. At this stage, 3D printers are used to manufacture products. It is a technology that constructs objects by printing layer by layer. The principle of 3D printer is to put data and raw materials into the 3D printer, and the machine will make the product layer by layer according to the program. The biggest difference between 3D printer and traditional printer is that the "ink" it uses is real raw material. There are various forms of stacking thin layers of raw materials, and there are various types of media that can be used for printing, from a variety of plastics to metals, ceramics and rubber substances. Some printers can also combine different media to make the printed object hard on one end and soft on the other.

[0003] When a graphene 3D printer is printing a product, the raw material is relatively soft when it is just squeezed out of the nozzle. At this time, the temperature of the raw material is high, the molding speed is slow, and it is easy to deform, which affects the product quality. In addition, most of the existing technologies cool down the product as a whole after printing, which reduces the work efficiency to a certain extent and increases the work intensity of the staff. For this reason, we propose a rapid freezing device for a graphene 3D printer to solve the problems existing in the existing technology. Summary of the invention
