Abstract

The invention provides a 3D printer monitoring error correction method. The method is used for monitoring whether errors occur in the printing process of a 3D printer and making timely and proper correction, and is characterized in that a system comprises three cameras and monitoring and error correcting software, wherein the three cameras are used for three-view monitoring and correspond to three view angles; the monitoring and error correcting software uses an image processing method for comparing the expected three views in each step in the printing process; whether the errors occur in the printing process or not is monitored and judged; repairable small errors are corrected in time; and errors which cannot be corrected are left uncorrected, so that the printing time is saved. The system has the advantages that the printing correctness is improved, and the average time for printing qualified products is reduced.

Description

technical field [0001] The invention relates to a 3D printing monitoring and error correction method based on three views, which is applied to the 3D field. Background technique [0002] 3D printing (3D Printing) was first proposed by Jim Bred and Tim Anderson of the Massachusetts Institute of Technology. They designed a device that can bond powder based on an ordinary inkjet printer, which became the earliest 3D printer. In March 2009, at the Roadmap for Additive Manufacturing (RAM) Workshop held in Washington, USA, it was officially determined to use the term Additive Manufacturing (AM) to refer to 3D printing technology. And made a plan for the development of rapid prototyping technology in the next 10 years. At present, the main lamination manufacturing technologies include Selective laser sintering (SLS), Stereolithography (SLA), Fused Deposition Modeling (FDM), etc. Its basic principle is stacked manufacturing. The rapid prototyping machine forms the cross-sectional ...
