External material receiving device of 3D printer and implementation method

Abstract

The invention provides a printing detection device of a 3D printer. The device comprises an X-axis encoder, a Y-axis encoder, a Z-axis encoder and a controller, wherein a rotating shaft of the X-axis encoder is connected with a synchronous belt of an X-axis stepping motor, a rotating shaft of the Y-axis encoder is connected with a synchronous belt of a Y-axis stepping motor, and the Z-axis encoder is connected with a Z-axis driving shaft by virtue of a Z-axis detection connecting device. Impulse signals are respectively sent to three stepping motors and a detection controller by a 3D printer controller, the stepping motors are execute components, the encoders are detection devices, the current angular position can be sent to the detection controller in real time by the encoders, the detected angular position is compared with a target value sent by the printer controller by the detection controller, and the detection controller gives an alarm when a detection value does not conform to the target value.

Description

technical field [0001] The invention relates to a 3D printer printing detection device and an implementation method, belonging to the technical field of three-dimensional printing. Background technique [0002] 3D printing is a form of additive manufacturing technology in which three-dimensional objects are created through successive physical layers. Compared with other additive manufacturing technologies, 3D printers have the advantages of fast speed, low price, and high ease of use. A 3D printer is a device that can "print" a real 3D object. It is functionally the same as the laser forming technology. It adopts layered processing and superposition forming, that is, it generates a 3D entity by adding materials layer by layer, which is different from traditional material processing technology. completely different. Calling it "printer" refers to its technical principle, because the process of layering processing is very similar to inkjet printing. [0003] The printer rea...

Problems solved by technology

However, since the filament output path of the printing nozzle is determined by the stepping motor in the three directions of X-Y-Z, the X and Y directions control the front, rear, left, and right paths of the printing nozzle through the synchronous belt, and the Z axis controls the up and down position of the printing table through the transmission shaft. , then the printing accuracy of the 3D printer depends entirely on the control accuracy of the stepping motors in the three directions. If a stepping motor loses step during the printing process, it will lead to deviations in the wire output path of the printing nozzle. , so that the printed model becomes a defective product, resulting in waste of materials and time
