In order to improve the manufacturing efficiency of shaped parts in the development and production of packaging machines,a digital twin monitoring system for light-curing 3D printers was designed,which can effectively ensure the quality of shaped parts produced by light-curing 3D printers.The virtual machine was constructed by Unity3D,the interactive device was constructed by Arduino development board,and the connection between the virtual machine and the physical machine was realized by serial communication.The system operates stably and can realize functions such as monitoring the operation status of light-curing 3D printers and monitoring key data such as printing layer thickness and molding platform attitude.Tests show that the printing layer thickness can be monitored with an accuracy of 0.01 mm,the molding platform attitude can be monitored with an accuracy of 0.001°,and the wrapper take-up roller production time can be reduced to 3.5 hours during normal printer operation.The research can provide some theoretical basis and new solutions for the rapid development and manufacturing of packaging machines.
