Abstract

The invention discloses an open type 3D printer based on cold printing. The open type 3D printer based on cold printing comprises a rack, a transmission system, a 3D printing nozzle and a printing platform. The printing platform comprises a leveling substrate and a model substrate located above the leveling substrate, wherein the outer side of the leveling substrate is provided with M limiting strips, the upper surface of the leveling substrate is provided with N positioning bosses, and at least two of the M limiting strips are oppositely arranged; and the upper surface of the model substrate is provided with a cold printed film, the lower surface of the model substrate is provided with N positioning magnets corresponding to the positioning bosses, the positioning magnets and the positioning bosses are attracted to each other when the positioning magnets make contact with the positioning bosses, so that the leveling substrate and the model substrate are fixed together, M is larger than or equal to 2, and N is larger than or equal to 2. The open type 3D printer based on cold printing can improve the model adhesive capacity, reduce model disengaging and edge warping and solve the problem of forming platform deformation caused by hot bed heating and other problems and meanwhile is high in transmission precision.

Description

technical field

[0001] The invention relates to the field of 3D printing rapid prototyping, in particular to an open 3D printer based on cold printing. Background technique

[0002] 3D printers with fusion technology are widely used in the consumer market due to open source technology and high sharing rate. At present, such consumer-grade 3D printers are generally made of sheet metal or PVC panels, so that the cost of materials and the stability of the structure cannot be increased synchronously. 3D printers with traditional fusion technology need to apply specific glue or stick masking paper on the heated base plate to bond the melted PLA / ABS material to the printing platform, and the base plate needs to maintain a certain temperature during the printing process, even so However, problems such as model falling off and edge warping are still common, and the platform will be deformed by long-term heating and destroy the gap between the print nozzle and the printing platform,...
