Example Embodiment

[0079] Example 1

[0080] figure 1 It is a flowchart of the 3D printing closed-loop control method in this embodiment. The 3D printing closed-loop control method is applied to a 3D printer, and the 3D printer includes a control module, a drive module connected to the control module, and a vision capture module connected to the control module. Wherein, the control module includes a processor and a memory, and a computer program is stored in the memory, and the 3D printing closed-loop control method is realized when the processor executes the calculation program. The driving module includes a printing nozzle arranged above the printing platform and a moving assembly for driving the printing nozzle to move along the X-axis, Y-axis and Z-axis directions. When printing, the control module controls the moving components to move along the X-axis, Y-axis and Z-axis directions, and controls the printing nozzle to melt, extrude and shape the thermoplastic material. The vision capture mod...

Abstract

The invention discloses a 3D printing closed-loop control method and device, a 3D printer and a storage medium. The 3D printing closed-loop control method comprises the steps of controlling a driving module to perform printing according to preset printing parameters of each layer in a preset data model, controlling a visual capturing module to capture actual printing parameters of a current printing layer in real time, calculating the actual error value of the actual printing parameters relative to the preset printing parameters, judging whether the actual error value is within a preset error range or not, obtaining compensation adjustment parameters and controlling the driving module to carry out next-layer printing on the basis of the compensation adjustment parameters if the actual error value is within the preset error range; and controlling the driving module to stop printing if the actual error value is not within the preset error range. According to the 3D printing closed-loop control method, by monitoring the abnormal effect in the printing process in real time, compensation control is performed or printing is stopped, and therefore the qualified rate of the printed product can be improved, and printing time and printing materials can be saved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing closed-loop control method, device, 3D printer and storage medium. Background technique [0002] 3D printing is a technology that uses Fused Deposition Manufacturing (Fused Deposition Modeling, hereinafter referred to as FDM) technology to print three-dimensional objects. In current 3D printers, the FDM process is used to input thermoplastic materials such as filamentous ABS and nylon into the printing nozzle. The thermoplastic material is heated and melted in the printing nozzle, and the printing nozzle is controlled by the driving mechanism along the cross-sectional contour and The filling trajectory moves to extrude the molten thermoplastic material, which solidifies rapidly and condenses with the surrounding materials to print out a three-dimensional object. [0003] Current 3D printers mainly use an open-loop control method to control the movement of the d...
