Intelligent data transmission system for 3D printer

The invention belongs to the technical field of 3D printing, and particularly relates to an intelligent data transmission system for a 3D printer. The system carries out simulation printing through the 3D printer, length data of required materials are measured when real objects are printed, the length data is compared with length data of required materials when a computer carries out simulation printing, finally, required material length is calculated when the real objects are printed, and the unnecessary trouble due to secondary addition of materials in the process of the printing of the realobjects can be prevented. Through coordination of servo motors and gears, column-shaped materials are sheared into grainy materials, and the specific surface area of the materials is enlarged so thatcontact area of materials to be heated and melted and melted materials is enlarged so that the melting efficiency of the materials can be accelerated. 本发明属于3D打印技术领域，具体的说是一种用于3D打印机的智能数据传输系统,该系统通过3D打印机进行模拟打印，测得实物打印时所需原料长度数据，并与计
