High-intensity multi-directional FDM 3D printing method based on stereoscopic vision monitoring

Abstract

Disclosed is a high-intensity multi-directional FDM 3D printing method based on stereoscopic vision monitoring. The method relates to the technologies of intelligent control and computer vision. Specifically, the method relates to building a multi-directional 3D printing hardware platform, stereoscopic visual detection, connection strength between all parts of a laser heating enhancement model, etc., so that the use of external support structures is weakened as much as possible on the premise of ensuring the printing precision, all parts of a model can be well connected, and the integrality ofthe model is enhanced.

Description

Technical field: [0001] This application involves related technologies of intelligent control and computer vision, researching high-intensity multi-directional FDM 3D printers and printing methods for stereo vision monitoring. It specifically involves the construction of a multi-directional FDM 3D printing hardware platform, stereo vision detection, laser heating to enhance the connection strength between various parts of the model, etc., so as to reduce the use of external support structures as much as possible while ensuring printing accuracy, and make each part of the model Parts can be well connected to enhance the integrity of the model. Background technique: [0002] In recent years, 3D printing has developed rapidly, but due to the high cost of materials and low printing accuracy, 3D printing has been limited in practical applications.

Problems solved by technology

[0002] In recent years, 3D printing has developed rapidly, but due to the high cost of materials and low printing accuracy, 3D printing has been limited in practical applications.

[0003] Traditional FDM 3D printers can only print in a single direction. In order to solve this problem, many experts are working on multi-directional FDM 3D printers, but most of the multi-directional FDM 3D printers use the method of splitting first and then printing. , the printing method divides the model into several parts and prints them separately, because the latter part needs to be repositioned and printed layer by layer after the previous part is printed, which puts forward high requirements for positioning accuracy. In addition, the printing of the latter part and the printing of the former part The direction is inconsistent, and the model that was printed first and supported the part to be printed has cooled down when printing the part to be printed, and there is a seam at the connection between the two parts, which destroys the integrity of the model
