Detection device and method of spray head mechanism of 3D printer

Abstract

The invention provides a detection device and method of a spray head mechanism of a 3D printer. The detection device includes but is not limited to the following components, an extrusion system, a pressure testing mechanism and a control system. The extrusion system is used for conveying, melting and extruding printing wires. The pressure testing mechanism is connected with the extrusion system soas to measure the extrusion pressure of the wires. The control system is connected with the extrusion system and the pressure testing mechanism. The device is adopted for detecting the spray head mechanism, the 3D printing wires can be molten and extruded according to different printing speeds, printing temperatures, pumpback distances and other parameters, the extrusion pressure, the outlet temperature, extrusion swelling, nozzle material leaking and other extrusion behaviors are tested and expressed, statistic analysis is carried out on testing data, adaptability of the tested wires and thespray head mechanism can be evaluated, and the optimal service conditions of the wires are found out.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a detection device and method for a nozzle mechanism of a 3D printer. Background technique [0002] Fused Deposition Modeling (FDM) process is a common 3D printing technology. Its materials are generally thermoplastic materials, such as PLA, ABS, nylon, etc., which are fed in a linear form, and the materials are heated and melted in the nozzle. The nozzle moves along the section profile of the part and the filling track, and at the same time extrudes the molten material, and the material solidifies rapidly and condenses with the surrounding materials to form a shape. [0003] Materials are the core of 3D printing technology, and nozzles are the core components of FDM 3D printers. Printing temperature and printing speed are the core parameters for materials to work on printers. However, at this stage there is no mature equipment and method for materials and nozzles. structure...

Problems solved by technology

[0003] Materials are the core of 3D printing technology, and nozzles are the core components of FDM 3D printers. Printing temperature and printing speed are the core parameters for materials to work on printers. However, at this stage there is no mature equipment and method for materials and nozzles. struct for a quick test to verify that the parameters match

Generally, you can only print a specific model through actual 3D printing, and then give feedback based on the printing quality of the model. There are too many interference factors in this process, and the test cycle is long
