Problems solved by technology

[0002] Most of the existing 3D printers have only one print head, and the printing efficiency is low. In the rare multi-head printers, the distance between the print heads is fixed and cannot be adjusted, and the number of print heads is small; It is continuous. When using a printer with a non-adjustable print head spacing, it is necessary to change the position of the print head during the printing process and then start printing again to print discontinuous shapes. Currently, it is cumbersome and difficult to print curved surface shapes through 3D printing.

Embodiment 1

[0024] A discontinuous columnar surface 3D printing structure, such as figure 1 As shown, it includes a rectangular base 1, four vertical rods of equal length are drawn perpendicular to the base 1 at the four corners of the base 1, and three horizontal rods parallel to the base 1 are connected between two adjacent rods. The three transverse bars between adjacent vertical bars are parallel to each other. These rod bodies form a frame-shaped integral frame 2 . The base 1 is located on the bottom surface of the overall frame 2 . In the middle position of the overall frame 2 in the vertical direction, a printing frame 3 is arranged, and the printing frame 3 is set as a rectangular plate whose outline matches the overall frame 2. A plurality of print heads 9 are arranged on the printing frame 3, and printing The discharge port of the head 9 is arranged towards the base 4 . Printhead 9 top is provided with feed pipe 12, as figure 1 As shown, all the print heads 9 are connected w...

Embodiment 2

[0034] A printer with the three-dimensional printing structure of a discontinuous columnar surface as described in Embodiment 1.

Embodiment 3

[0036] A three-dimensional printing method for a discontinuous columnar curved surface. The printing device can be used to print discontinuous cylindrical curved surface objects, which can be applied to two scenarios. The discontinuous cylindrical surface shape of .

[0037] If you choose the first printing method to print the surface shape of discontinuous columns with equal intervals, the printing steps are as follows:

[0038]A) First, select the corresponding print head 9 according to the needs of the printed object, determine the number of the selected print head 9, replace the print nozzle with a suitable caliber, and then slide the selected print head 9 on each horizontal thin rail 8, refer to the horizontal thin rail 8 The scale on the rail 8 adjusts the position of the print head 9 to an equal distance and fixes it; then slide the two ends of each horizontal thin rail 8 on the longitudinal slide rail 11, and adjust the horizontal thin rail 8 to each horizontal thin ra...

Abstract

The invention discloses a three-dimensional printing structure of a discontinuous columnar curved surface, which comprises an integral frame, a printing frame arranged on the integral frame, a plurality of printing heads are arranged on the printing frame, and a height adjustment component, The horizontal moving assembly and the vertical moving assembly; the height adjustment assembly includes longitudinal guide rails arranged on the overall frame, the horizontal moving assembly includes horizontal guide rails, the bottom of the overall frame is provided with a base, and the horizontal guide rails are attached to the base and parallel to the horizontal thin rail, perpendicular to the longitudinal rail. The vertical moving component includes a vertical slide rail set on the printing frame, and a horizontal thin rail is slidingly connected in the vertical sliding rail, and the print head is mounted on the horizontal thin rail; the printing frame, the printing table, and the horizontal thin rail are equipped with independent driven by the motor. The print frame is a rectangular frame, the longitudinal slide rails are attached to the long sides of the print frame, and the horizontal thin rails are always parallel to the short sides of the print frame. The horizontal thin rails are independent of each other, and the print heads on the same horizontal thin rail are independent of each other.

Description

technical field [0001] The invention relates to a three-dimensional printing structure of a discontinuous columnar curved surface, a printer and a printing method, and belongs to the technical field of three-dimensional printing. Background technique [0002] Most of the existing 3D printers have only one print head, and the printing efficiency is low. In the rare multi-head printers, the distance between the print heads is fixed and not adjustable and the number of print heads is small; It is continuous. When using a printer with a non-adjustable print head spacing, it is necessary to change the position of the print head during the printing process and then start printing again to print discontinuous shapes. Currently, printing curved surface shapes through 3D printing is still relatively cumbersome and difficult. Contents of the invention [0003] The purpose of the present invention is to provide a three-dimensional printing structure of discontinuous columnar curved s...
