Description

technical field [0001] The present invention specifically relates to the technical field of 3D printing, in particular to a wireless transmission control device and method for 3D printing that is stored, shared and invoked. Background technique [0002] 3D printing, also known as additive manufacturing technology, is a manufacturing technology that uses the principle of layered manufacturing and superposition to directly manufacture three-dimensional solid parts from CAD models. The biggest advantage of processing and manufacturing parts of polymer materials, ceramics, metals and various composite materials is that it can form parts of any complex structure, and can realize the one-time integral forming of parts without assembly and the integrated forming of materials and structures. It has been widely used in aerospace, biomedical, and automotive industries. [0003] However, the traditional 3D printers often use the memory card as an intermediary to transmit model data. E...

Problems solved by technology

[0003] However, the traditional 3D printers often use the memory card as an intermediary to transmit model data. Each printing requires the insertion, removal and transfer of the memory card, and then the printing operation on the printer. The whole process is time-consuming, laborious and cumbersome; The operation is also connected to the computer through the data cable and the network cable, and then the computer is used to control the printing. Due to the limitation of the data cable, the wiring setting is relatively cumbersome, which limits the location of the printer and affects the office environment. In addition, the way of wired connection is also The distance of remote operation is limited, and only short-distance data transmission and printing control can be realized; therefore, it is of great significance to develop an efficient and convenient wireless transmission control device and method for 3D printing

[0004] At present, the existing wireless 3D printing schemes adopt the form of upper computer and serial communication; for example, CN112346676A discloses a 3D printing online control experience system, the system includes: a user terminal; a centralized control module; The 3D printing equipment connected to the control module, its user terminal and the centralized control module are the upper computer; CN112549555A discloses a 3D printing remote online monitoring method and system based on the cloud platform, and the remote terminal module uploads user information and sends it to the upper computer through the cloud platform The upper computer generates control commands according to the 3D printer data carried in the user information and sends the 3D printer to print; the use of the upper computer for wireless transmission control has complex structure and high cost, and the upper computer needs to be connected online during the 3D printing process. , and the 3D printing of large models often takes tens of hours or more, which consumes a lot of energy and puts forward higher requirements on the stability of the upper computer; using the form of serial communication For example, CN106584862A announced a 3D printing WIFI with built-in Web services The control system and its control method adopt the serial port communication between the ESP8266 module and the mainboard interface, and its data transmission speed is limited by the serial port standard and the data processing capability of the control board IC chip (Integrated CircuitChip), which can only reach 25KB / s. Existing model data of tens of MB takes a long time and cannot be used in practice
