3D printing equipment having real-time detection feedback function

Abstract

The invention relates to 3D printing equipment having a real-time detection feedback function. The equipment comprises a workbench, a supporting column, a cross beam and a printing mechanism. In the equipment, air cylinders control up-and-down movement of a lifting rod, more accurate height adjustment of a printing nozzle can be realized through a distance sensor, besides, a telescopic motor controls the printing nozzle to move horizontally through a telescopic rod, meanwhile, the moving accuracy of the printing nozzle is further improved through a speed reducer, and the printing reliability is improved; in addition, in a working power supply circuit, the model of an integrated circuit is MAX688 and has the characteristics of low working current and high driving current, and thus, the high-power motor can be driven; meanwhile, output power is further amplified through a power amplification circuit mainly comprising a first triode and a second triode, the reliability of a driving motor is guaranteed, and the practical value and the reliability of the printing equipment are improved.

Description

technical field [0001] The invention relates to a 3D printing device with real-time detection and feedback functions. Background technique [0002] 3D printer, as the name suggests, is a printer that is small in size and can be placed on a desk to print three-dimensional objects; desktop 3D printer is a machine of rapid prototyping technology, which is based on digital model files, using powdered metal or plastic Adhesive materials such as adhesive materials, the technology of constructing objects by layer-by-layer printing; in the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products, which means that this technology is spreading; [0003] Existing 3D printing equipment sends instructions directly through the central control in the process of moving the print head, and there are moving devices such as motors and cylinders to drive the movement of the print...

AI Technical Summary

Problems solved by technology

[0003] Existing 3D printing equipment sends instructions directly through the central control in the process of moving the print head, and there are moving devices such as motors and cylinders to drive the movement of the print head. Although this can achieve reliable movement of the print head, However, due to the lack of reliable feedback detection capability, the accuracy of printing is not enough, which reduces the reliability of printing equipment; not only that, in the process of printing equipment working, the working power circuit is in order to be able to drive a large current motor. The basic current of the circuit is also relatively large, which increases the loss of the power circuit and reduces the practical value of the printing equipment
