Abstract

The invention provides a monitoring and error correction method for a 3D printer, which is used to monitor whether an error occurs during the printing process of the 3D printer, and make timely and appropriate corrections. It is characterized in that the system includes: 3 cameras for three-view monitoring , 3 cameras correspond to 3 viewing angles; the monitoring and error correction software uses image processing to compare the expected three views of each step in the printing process, judges whether the monitoring printing is wrong, and makes timely corrections to small repairable errors. Discard errors that cannot be corrected to save printing time. This system has the advantages of improving the printing accuracy rate and saving the average time for printing qualified products.

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 A plan is made 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-section...
