Hollowed-out ceramic 3D printing method of XZA rotating shaft 3D printer and control method

Abstract

The invention provides a hollowed-out ceramic 3D printing method of an XZA rotating shaft 3D printer and a control system. The hollowed-out ceramic 3D printing method comprises the steps that texture, texture density and related printing information are determined; according to the texture density, path planning is performed in a two-dimensional plane, and a path point set a in the two-dimensional plane is preliminarily generated; basic shape information is read, a basic shape is parameterized into a rectangular area determined according to the texture density, the path point set a is mapped to an XYZ space, and a path point set b of the XYZ space is obtained; the path point set b is mapped to the XZA space, and a path point set c of the XZA space is obtained; and a printable G-code file is determined according to the path point set c, and the printable G-code file is output for printing. Continuous-path hollow ceramic 3D printing is realized, the influence caused by the gravity of clay and the low drying speed of the clay can be reduced, the success rate of hollow ceramic 3D printing is increased, and the quality of hollow ceramic 3D printing is improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a hollow ceramic 3D printing method and a control system of an XZA rotary axis 3D printer. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Ceramics have the advantages of excellent corrosion resistance, high temperature resistance, high hardness, high mechanical strength, low density, low water absorption, etc., and have been widely used in daily life, building sanitation, chemical electrical and other fields. There are many kinds of traditional ceramic products with different performances. With the rise of high-tech industry, various new special ceramics have also achieved great development. Ceramics are increasingly becoming good structural and functional materials. [0004] Hollowing is one of the traditional decorative tec...

Problems solved by technology

However, when using clay to print the hollow design, due to the gravity of the clay itself and the slow drying speed of the clay, it will collapse during the manufacturing process, resulting in the failure of printing; even if the support is added to reduce the occurrence of collapse, but the printing support It will increase the printing time, and the removal of the second support is a very troublesome thing, and even affect the quality of the printed product; there is also a very important point, in ceramic 3D printing, the discontinuity of the printing path will affect the opening of the nozzle. Closed, thus affecting the printing quality and accuracy, and the layer-by-layer printing hollow structure in XYZ space is difficult to ensure the continuity of the path

This poses new challenges to the digital design and manufacture of hollow ceramics
