Abstract

The present invention provides a machine vision-based 3D printer broken wire alarm device and alarm method. The 3D printer includes an extruder and a lifting platform. The produced model is set on the lifting platform and below the extruder, and the machine vision-based 3D printer broken wire alarm device includes a camera, and the camera is set on the side of the extruder nozzle. The invention overcomes the need to make changes to the hardware, starts from the idea of ​​software, and detects the broken wire (no material) of the 3D printer based on the principle of machine vision, so as to issue an alarm and suspend printing, so as to remind the staff, save printing materials and promote printing. Purpose of work progress.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a machine vision-based 3D printer broken wire alarm device and an alarm method, which are used for the broken wire (no material) alarm of various FDM 3D printers based on fused deposition rapid prototyping. Background technique [0002] With the rapid development of 3D printing technology, 3D printers play an important role in production, scientific research and even daily life. The widespread application of 3D printers has also brought some common problems, such as broken wires caused by extruder nozzle blockage or material deterioration, which will cause waste of materials and time. At the same time, it will affect the work to a certain extent. progress. [0003] The existing technical solution is basically to change the relevant hardware of the 3D printer and add a photoelectric sensor to realize the detection of the discharge of the extruder nozzle. Supplies...
