Embodiment 1

[0048] The automatic leveling method applied to 3D printing in this application refers to constructing the fitting plane between the datum plane and the printing platform first, and the fitting plane is the real plane of the printing platform, and then calculates the position and datum of each point on the real plane through a certain algorithm. The error value between the planes, so as to obtain the compensation value required by the print head on the z-axis. Including the following steps:

[0049] S11: Obtain the three-dimensional coordinate values ​​of a reference point and four compensation points on the printing platform.

[0050] Such as figure 1 As shown, this step refers to detecting the three-dimensional coordinate values ​​of a reference point and four compensation points on the printing platform through the detection unit provided on the print head, and the detection unit is specifically a tact switch or a light detection instrument. include:

[0051] The detecti...

Embodiment 2

[0067] Such as figure 1 , image 3 As shown, the automatic leveling system applied to 3D printing in this application includes a printing platform 10, a printing head 20 for ejecting printing materials, a detection unit 30, and a calculation control unit (not shown). The detection unit 30 is installed on the print head 20, and the print head 20 includes an extrusion head holder 21, an extrusion head 22 installed at the lower end of the extrusion head holder 21, and an extrusion head located on the extrusion head holder 21. Out of the nozzle 23 at the bottom of the head 22. The detection unit 30 includes an electromagnet 31 installed on the print head 22, a fulcrum 32, a rotating arm 33 rotatably installed on the fulcrum 32 and one end connected to the electromagnet 31, and an arm 33 installed on the fulcrum 32. The tact switch 34 at the other end of the rotating arm 33 . During leveling detection, the electromagnet 21 is energized, and the light touch switch 34a of the dete...

Abstract

An automatic leveling method for 3D print includes: acquiring three-dimensional coordinate values of one reference point and four compensation points of a print platform; constructing a reference plane and a fitting plane according to the reference plane and the four compensation points; calculating a compensation value of the fitting plane with respect to the reference plane; and adjusting the height of a z axis of a print head according to the compensation value so as to perform printing. The automatic leveling method can effectively reduce errors of 3D print.

Description

technical field [0001] The present application relates to the field of 3D printing, in particular to an automatic leveling method applied to 3D printing and a tuning method using the algorithm. Background technique [0002] 3D printing is a technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing based on digital model files. 3D printing is usually achieved using digital technology material printers, the technology has been applied in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems , civil engineering, firearms and more. [0003] In 3D printing, the printing head is used to print layer by layer on the printing platform. After each layer is printed, the printing platform moves down one layer in the Z-axis direction, and the printing head then prints the next layer. However, in...
