Problems solved by technology

[0002] In the print head part of 3DP sand core printer, the control board is a precision component, and the working temperature requirement is high. When the control board works, it will generate a lot of heat. Excessive heat will affect the life of the board, and the board is expensive, which will increase Printing cost, the current one is an open structure, and the printing materials will have dust phenomenon, the dust adheres to the control board and other precision components in the print head, and also adheres to the inside of the nozzle, so that being covered by dust will hinder the work of the board , the dust cleaning work is more complicated, on the one hand, it will affect the follow-up board work, on the other hand, it will affect the work efficiency and work accuracy

Description

technical field [0001] The invention relates to the field of additive manufacturing 3D printing equipment, in particular to a printing head, a printing method, a printing system, a storage medium and a printing equipment. Background technique [0002] In the print head part of 3DP sand core printer, the control board is a precision component, and the working temperature requirement is high. When the control board works, it will generate a lot of heat. Excessive heat will affect the life of the board, and the board is expensive, which will increase Printing cost, the current one is an open structure, and the printing materials will have dust phenomenon, the dust adheres to the control board and other precision components in the print head, and also adheres to the inside of the nozzle, so that being covered by dust will hinder the work of the board , The dust cleaning work is more complicated. On the one hand, it will affect the subsequent board work, and on the other hand, it...
