Abstract

The invention relates to a use duration detection method and device of a printing nozzle, a printer and a storage medium. The method comprises the steps that a printer obtains the wear rate of a printing nozzle in the printing process and the duration needed by the printing process, obtains the historical accumulative use duration of the printing nozzle, determines the current accumulative use duration of the printing nozzle according to the wear rate of the printing nozzle, the duration needed by the printing process and the historical accumulative use duration, and sends the current accumulative use duration to the printer; according to the current accumulated use duration and a preset use duration threshold value of the printing nozzle, whether the printing nozzle needs to be replaced or not is determined; namely, according to the wear rate and the printing duration of the printing nozzle in each printing process, the accumulated use duration of the printing nozzle is accurately calculated, the accuracy of printing nozzle use duration detection is improved, a user can be timely reminded to replace the printing nozzle, and the user experience is improved. The problem of consumable waste caused by substandard quality of a printed model due to serious abrasion of the printing nozzle is avoided, and the detection efficiency of the use duration detection of the printing nozzle is improved.

Description

technical field

[0001] The present application relates to the technical field of 3D printing, and in particular to a method, a device, a printer, a storage medium and a computer program product for detecting the usage time of a printing nozzle. Background technique

[0002] In the field of 3D printing technology, especially the 3D printing technology using fused deposition modeling (Fused Deposition Modeling, referred to as FDM) technology, the printed 3D three-dimensional model is formed by accumulating layers of consumables through the nozzle of the printer. For the printer nozzle, during long-term use, the quality of the model printed by the printer cannot meet the printing quality standard due to the wear of the consumables on the printer nozzle, indicating that the nozzle has been worn out and cannot be used normally, and the nozzle needs to be replaced.

[0003] In the traditional technology, usually by analyzing the actual printed model, it is judged whether the quali...
