Unlike traditional subtractive manufacturing methods, 3D printing forms objects by gradually adding materials, with high flexibility and customizability, widely used in prototyping, product design, medical, aerospace and other fields.

[0003] For example, Chinese utility model patent (CN106239921A) discloses a visual safety protection cover for 3D printer, which is described as: "the outer side of the middle part of the protection door B is provided with electric control lock B and handle B, the lower part of the inner cavity of the protection cover body is provided with a workbench, the front side and the rear side of the lower part of the inner cavity of the protection cover body are provided with a ventilator, the electric control lock A and the electric control lock B are connected with a control switch through a signal line, and the electric control lock A and the electric control lock B are connected with an alarm device through a signal line. The present application has the advantages of good ventilation and heat dissipation effect, convenient movement, high safety performance and simple operation", and also describes the technical problems of "the design structure of the existing visual safety protection cover for 3D printer is often relatively simple, and the ventilation and heat dissipation effect is not good. When opening and closing, the operation is not simple enough. In addition, when the whole needs to be moved, the operation is relatively complex and inconvenient, and there are certain defects".
