High-precision nozzle clogging detection and processing system and detection and processing method

Abstract

High-precision nozzle blockage detection processing system and detection processing method, the high-precision nozzle blockage detection processing system includes an initial value setting module, a current print product thickness retrieval module, a current print thickness detection module, a comparison module, an instant position recording module, and a reset drive module, and the homing drive module. The initial value setting module is used to record the initial printing position of the wire feeding motor. The comparison module is used for timely comparing the design thickness value with the current thickness value. The instant position recording module is only used to record the instant printing position of the wire feeding motor. The homing drive module is used to stop the wire feeding motor from feeding the wire and drive the extruder head back to the initial printing position for maintenance of the extruder head. As long as the current printing thickness is less than the design thickness, the high-precision nozzle clogging detection and processing system considers that the nozzle is blocked, so that it can accurately detect that the nozzle is blocked. The invention also provides a detection method.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a high-precision nozzle clogging detection and processing system and a detection and processing method. Background technique [0002] 3D printing technology refers to the technology of generating three-dimensional entities through continuous physical layer superposition and adding bondable materials such as powdered metal or plastic layer by layer. It is different from traditional material removal processing technology, so it is also called additive manufacturing or Laminate manufacturing. 3D printing technology covers all printing processes, technologies, equipment categories and applications related to "rapid prototyping" at the front end of the product life cycle and "rapid manufacturing" in the full production cycle. 3D printing has a high technical content, which integrates cutting-edge technical knowledge in many aspects such as digital modeling technology, i...

Problems solved by technology

The above-mentioned detection devices and detection methods have low precision, because the signals have delays or errors, and cannot be adapted to most 3D printers, and sometimes the printed products will be damaged due to blocked nozzles
