Intelligent 3D printing substrate leveling system and 3D printer

Abstract

The invention relates to an intelligent 3D printing substrate leveling system. The intelligent 3D printing substrate leveling system comprises a bearing substrate, a forming substrate fixed to the bearing substrate, four distance sensing devices located in the same horizontal plane, a numerical control unit storing a preset distance and a drive device. The plane is defined as a datum plane. The four distance sensing devices and the bearing substrate are located on the two back-to-back sides of the forming substrate correspondingly. The four distance sensing devices are aligned with the four corners of the forming substrate at intervals correspondingly and used for sensing the distance between the four corners of the forming substrate and the datum plane so as to output four distance signals. The numerical control unit receives four distance signals and calculates four distance deviations between the four distance signals and the preset distance. The drive device is movably connected with the bearing substrate, and at least three movable connecting positions are defined. The drive device drives the bearing substrate to ascend, descend or rotate relative to the movable connecting positions according to the four distance deviations so that the four distance deviations can be in the preset deviation range. The invention further provides a 3D printer.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing substrate intelligent leveling system and a 3D printer equipped with the 3D printing substrate intelligent leveling system. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of rapid prototyping technology, based on digital model files, using metal or non-metallic materials to form powder, melting / melting the laid flat powder to be formed layer by layer, and then Solidification build-up molding to construct three-dimensional solid printing equipment. With the rapid development of 3D printing technology, 3D printers have been widely used in product manufacturing. Among them, the molding substrate is an important part of the 3D printer. The molding substrate is usually set in the molding cylinder. Whether the molding substrate is flat or not determines the printing efficiency and printing yield of the 3D printer when pri...

Problems solved by technology

However, the traditional adjustment method is manual adjustment. On the one hand, due to the heavy molding substrate, the adjustment is time-consuming and laborious, which affects the printing efficiency of the 3D printer; on the other hand, manual adjustment cannot guarantee the adjustment accuracy, which affects the printing quality of the 3D printer.
