Problems solved by technology

[0003] At present, the laser energy of 3D printers is relatively low, and it is impossible to achieve high melting point (melting point over 1200°C) jade powder is melted and sintered during the printing process, so the current 3D printing technology is mainly used to print metal alloy materials or plastic products
After reviewing literature and patents, the existing 3D printing technology cannot directly use jade powder as a raw material to print and prepare jade articles, and there is no powder raw material suitable for direct use in 3D printing jade articles
Because the inorganic high-melting point jade powder raw material cannot achieve densification and sintering during the printing process, resulting in inaccurate molding after printing
Existing 3D printing generally uses some polymers or inorganic sols as binders for molding, but if these raw materials are directly used as binders in 3D printing jade powder, they need to be eliminated through post-calcination to make jade products There are many pores, even if these pores are calcined at a high temperature, the densification of the jade product cannot be achieved, and even the jade product will be deformed and collapsed, and the compactness, optical beauty and original designed appearance of the jade product will be lost.

Abstract

The invention discloses a method for preparing jade wares by adopting 3D printing technology. The main method is: using high-purity and high surface activity Al2O3 powder, ZrO2 powder, TiO2 powder or MgO powder as the jade matrix powder material, and using metal Al powder, Mg powder, Fe powder or Ti powder are sintered phase powder materials, and powders containing coloring atoms such as trace nanometer Fe powder, Cu powder or Co powder or oxides or chlorides of these elements are used as colorant powders , select one or several of them and pre-mix them in a certain proportion; use a small amount of organic wax or aluminum sol as a binder; use a laser 3D printer to print jades of different shapes. If the appearance density is not perfect after printing, the jade product can be further heat-treated and densified to obtain a perfect jade product. The corundum, spinel or zirconium jadeware prepared by the invention has the characteristics of simple process, direct molding, no need for later cutting and engraving, high production efficiency, and low preparation cost.

Description

technical field [0001] The invention relates to a method for preparing jade wares, in particular to a method for preparing jade wares using 3D printing technology. Background technique [0002] Jade is usually prepared from natural jade through a series of processes such as carving, grinding, and polishing. Generally speaking, the preparation of a high-quality jade product with a complex structure takes a long time, sometimes requiring skilled technicians to spend months or even years. It needs to be carved and polished to complete. With the advancement of human civilization, the demand for jade continues to grow. Natural jade is a limited underground mineral resource. Human beings have accelerated the speed of jade mining for immediate benefits, which has increased the contradiction between limited resources and unlimited demand. Therefore, adopting new technology to prepare artificial jade articles, thereby reducing the mining of natural jade resources, has become an impo...
