Problems solved by technology

At present, this kind of 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 increase 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 , problems such as model falling off and edge warping are still common, and the platform will be deformed after long-term heating and destroy the gap between the print nozzle and the printing platform, which will significantly affect the quality of model printing and increase printing costs.
On the other hand, only one end of the printing platform of the transmission fusion 3D printer is connected to the transmission mechanism, forming a cantilever beam, which eventually leads to poor transmission accuracy or even failure

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0025] Such as figure 1 As shown, an open 3D printer based on cold printing adopts the basic principles and working parts of 3D printers. On the basis of analyzing the problems existing in existing hot bed heating 3D printers, some structures and systems are redesigned and innovated. , including frame 1, transmission system 2 and printing platform 4.

[0026] Most of the existing hot bed heating 3D printers are made of sheet metal structures or spliced ​​PVC panels, resulting in high manufacturing costs or poor physical structure stability. In view of this, the cold printing open 3D printer developed by the present invention adopts a skeleton structure design for its frame 1 . It is mainly composed of bottom positioning angle code 11, optical axis 12 and top positionin...

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,...
