Method of preparing jade-ware by applying 3D (Three-Dimensional) printing technology

Abstract

The invention discloses a method of preparing jade-ware by applying a 3D (Three-Dimensional) printing technology. The method comprises the main steps: taking Al2O3 (Aluminum Oxide) powder, ZrO2 (Zirconium Dioxide) powder, TiO2 (titanium dioxide) powder or MgO (Magnesium Oxide) powder as a jade-ware matrix powder material, taking metal Al powder, Mg power, Fe Power or Ti power as a sintering phase powder material, taking nano-trace Fe powder, Cu powder or Co powder or the powder of oxides or chlorides of the elements and the like containing color powder as colorant powder, and respectively selecting one or more elements to mix in advance according to a certain proportion; preparing a small amount of organic wax or alumina sol into a bonding agent; and printing the jade-ware of different appearances by a laser 3D printer. The jade-ware can be further thermally processed and compacted to prepare a perfect jade-ware finished product if the appearance and density of the jade-ware are not perfect after the printing. According to the method of preparing the jade-ware by applying the 3D printing technology, the corundum, corundum or zirconium jade-ware has the characteristics of being simple in process, high in production efficiency, direct to form and low in preparation cost, the later cutting and carving cannot be needed and the like.

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 i...

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.
