Embodiment Construction

[0014] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0015] Such as figure 1 Shown is a device for calibrating the relative coordinates of the output port of a multi-nozzle 3D printer. The 3D printer includes a printing bed 4, printing nozzles, a three-dimensional translation platform and a control system.

[0016] Described three-dimensional translation platform comprises the Z-axis left translation platform 7 and the Z-axis right translation platform 8 that are arranged apart from each other, and the X-axis translation platform 5 and X-axis translation platform 5 are arranged between the Z-axis left translation platform 7 and the Z-axis right translation platform 8 bottoms. A Y-axis displacement platform 6 is...

Abstract

The invention relates to a device for calibrating relative coordinates of a discharge port of a multiple-nozzle 3D printer. The 3D printer is provided with a print bed, at least two nozzles arranged above the print bed, a three-dimensional displacement table and a control system; a fixing table is installed on the print bed, and a first photoelectric switch and a second photoelectric switch are arranged on the fixing table; and an optical path of the first photoelectric switch is perpendicular to the YZ motion plane of the three-dimensional displacement table, and an optical path of the secondphotoelectric switch is perpendicular to the XZ motion plane of the three-dimensional displacement table. According to the device, through movement of the first and second photoelectric switches, therelative position coordinates of the nozzle discharge port on XYZ axes are measured through the first and second photoelectric switches, and accordingly calibrated; and thus, the problem of positionchange of the discharge port due to nozzle replacement in the multiple-nozzle 3D printing technology can be solved, and the molding effect is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a relative coordinate calibration device for a discharge port of a multi-nozzle 3D printer. Background technique [0002] 3D printing technology is a material molding technology based on digital models. At present, it can realize the controllable molding of any geometric structure of materials including metals, thermoplastic resins, photosensitive resins, and hydrogels. Recently, on the basis of single material 3D printing technology, multi-nozzle 3D printing technology has been developed to meet the molding of complex structural multi-material parts. When using multi-nozzle 3D printing technology, the position of the outlet will be shifted before and after replacing the nozzles. This shift will easily affect the alignment accuracy of the relative positions of different materials, and then affect the molding effect. Contents of the invention [0003] The technical problem ...
