Abstract: Based on the Delta parallel the advantages of mechanical structure than Descartes'mechanical structure,
and use it to 3D printer research and design, this paper puts forward a kind of Delta structure, low cost, network design of 3D printer. Compared to the more widespread use of 3D printers Cartesian coordinate system, the Delta type 3D printers allow greater volume and faster printing speed. The printer uses STM32 microcontroller as the core controller, with stepping motor as driving element, by stepping motor drives the synchronous belt, use the slider control the print head according to the predetermined path. To reduce the weight of the print head, improve the print speed, using the remote transmission mechanism, and through the stepper motor feeding, digital temperature control, to complete the print head print jobs. In order to speed up the promotion and use of 3D printers, the internet 3D printing solutions are put forward, equipped with WiFi module implements wireless data transmission and remote control, and increase the function of the automatic leveling, power outages to continue, broken wire detection, great-ly enhance the use of 3D printers and convenience. Practice shows that the printer has the advantages of the smooth movement, high speed, high precision, low cost, easy to control.
