Embodiment Construction

[0027] like figure 1 As shown, the 3D printer fault detection method of the present invention comprises the steps:

[0028] (1) Before the 3D printer starts feeding and heating, detect the temperature of the space where the heating component of the 3D printer is located, and record it as the first ambient temperature;

[0029] (2) Turn on the 3D printer, detect the feeding amount of the feed port, record the ratio of the feeding amount of the material relative to the time, and record it as this ratio;

[0030] (3) When the ratio this time is greater than a predetermined threshold, detect the temperature of the heating component of the 3D printer, and record this temperature as the first material temperature; the predetermined threshold here is generally determined according to the model of the specific 3D printer and the selected material of. For example, for the AURORA 3D printer, using MakerBotPLA blue filament, the threshold here can be set to 4.3mm / s.

[0031] (4) Detec...

Abstract

The invention provides a 3D printer fault detection method, which particularly aims at a temperature aspect, solving the problem in the prior art that 3D printer fault detection is lack of repeated effect. With the adoption of the method, the complicated application requirements can be met by the sensitivity and control flexibility of a 3D printer under situations that temperature difference is relatively small and control requirements are precise when the 3D printer is used for producing fused materials such as the situations of medical device products and complex type workpieces.

Description

technical field [0001] The present invention relates to the technical field of 3D printer fault detection, and more specifically, to a method for detecting a temperature fault of a 3D printer. Background technique [0002] With the continuous advancement of 3D printing technology, people have put forward higher requirements for the function, performance and reliability of 3D printers. As an emerging processing equipment, 3D printers have increasingly broad application prospects and market potential. At present, most 3D printers on the market are based on the principle of FDM, that is, the principle of fused deposition manufacturing. The raw materials of this type of 3D printer are generally thermoplastic materials, such as wax, ABS, nylon, etc. It is very important for temperature detection. [0003] In the prior art, Chinese patent application CN201410489881.8 discloses an online monitoring device for the working status of a 3D printer. It includes a data acquisition an...
