Model identification and internal model control system based on 3D printer

Abstract

The invention discloses a model identification and internal model control system based on a 3D printer. The system comprises the 3D printer, a PC terminal and a human-computer interface. A serial businterface of the PC terminal is connected with a serial bus interface of the 3D printer through a data cable. The hardware operating platform of the human-computer interface is the PC terminal while the software operating platform is LABVIEW. The model identification and internal model control system based on the 3D printer comprises the steps including step one, model identification; step two, establishing of a laser temperature control system; step three, encapsulation of a dynamic link library; and step four, user interface design. The model identification and internal model control systembased on the 3D printer has the advantages of simple control parameter, intelligent control, high automation degree and one-time implementation.

Description

technical field [0001] The invention belongs to the technical field of modeling and control of a temperature system of a 3D printer, and in particular relates to a modeling method and a control strategy of the system. Background technique [0002] 3D printing technology is an emerging rapid prototyping technology. Because the realization of its process relies on computer technology, intelligent control technology, electromechanical technology and material properties, etc., this technology has received extensive attention. It has been used in food processing, biomedicine, mold manufacturing, aerospace and other fields. With the development and popularization of 3D rapid prototyping technology, Professor Yan Yongnian of Tsinghua University took the lead in forming his own scientific research team, and successfully designed and developed the prototype of the first domestic rapid prototyping equipment at that time. Subsequently, Academician Lu Bingheng's team of Xi'an Jiaotong...

AI Technical Summary

Problems solved by technology

However, for the development of domestic rapid prototyping technology, due to the relatively late start of domestic 3D printing technology, the entire 3D printing market is almost occupied by developed countries such as the United States and Europe, and China only occupies a small part of it. In order to be able to seize the 3D printing market, and To gain technical advantages in technology research and development, it is urgent to develop and research 3D printing technology
