Real-time levelness monitoring system for workbench of 3D (three-dimensional) printer

Abstract

The invention discloses a real-time levelness monitoring system for a working platform of a 3D (three-dimensional) printer. When the area of the working platform is larger than 500*500mm<2>, the system comprises four biaxial inclination angle sensor modules, a micro controller, four indicating lamps and a buzzer, wherein the four biaxial inclination angle sensor modules are respectively arranged and fixed at middle positions on the rims of the four surfaces on the lower side of the working platform; the micro controller is connected with the four biaxial inclination angle sensor modules respectively through chip selection ports CSX; the chip selection ports control connection and disconnection between the micro controller and the four biaxial inclination angle sensor modules; the data input end and the data output end of the micro controller are respectively connected with the data output end and the data input end of each biaxial inclination angle sensor module; the clock signal end of the micro controller is connected with the clock input end of each biaxial inclination angle sensor module; the four indicating lamps are connected with the buzzer and the micro controller. The real-time levelness monitoring system achieves definiteness and accuracy, improves the leveling efficiency, realizes real-time monitoring and alarming functions and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a real-time level monitoring system for a 3D printer workbench. Background technique [0002] A 3D printer, also known as a three-dimensional printer, is a machine of rapid prototyping technology, and a 3D printer prints a digital model into a physical object based on rapid prototyping technology. The square working platform of the 3D printer is an important structural part of the 3D printer and plays the role of carrying the model. The levelness of the working platform directly affects the quality of the printed model. When the working platform is uneven, the 3D printer will warp the bottom layer of the model, print unevenly, and even fail to adhere to the working platform. Therefore, the first task before printing the model is to check and level the 3D printer working platform. At present, the levelness monitoring and leveling of the 3D printer working platform are mostly completed by the operator manually adjusting the lev...

AI Technical Summary

Problems solved by technology

At present, the levelness monitoring and leveling of the 3D printer working platform are mostly completed by the operator manually adjusting the leveling nuts at the four top corners by feeling. Because the operation is cumbersome, the accuracy is difficult to control, and it takes a long time, the operator is required to master a certain amount of time. skills and experience

Even after the working platform is leveled, every time a model is printed, the working platform may deflect slightly and it is not easy to detect

This requires the operator to check the level of the working platform from time to time, but it cannot realize real-time monitoring of the level of the working platform, and each manual leveling has a certain degree of blindness
