Problems solved by technology

Disadvantages of this process: First, the effective contact area between germanium particles and the human body is too small, which is a serious waste for expensive and scarcely stored germanium materials, and the inlaid germanium particles are easy to fall off; second, this simple inlay The process mode severely limits the flexibility and artistry of silver germanium jewelry design, and the products often appear rough and clumsy, not exquisite enough, which affects its aesthetic experience as a fashion jewelry
However, the smelting and processing of silver-germanium are quite difficult. Silver-germanium alloys have high hardness, high brittleness, and poor flexibility. It is difficult to plastically process them into exquisite and delicate ornaments like ordinary silver, especially those with high germanium content. alloy

Embodiment 1

[0023] The Ag alloy was smelted in the following weight percentages: Ag (94.5%) - Cu (2.1%) - Si (1.2%) - Zn (2.2%). The above Ag alloy is melted and then made into spherical powder by gas atomization, and the fine powder below 500 mesh is screened out. Ge powder is a commercially available 5N grade pure germanium powder, which is a brittle powder obtained by mechanical crushing. The fine powder below 500 mesh is screened. After weighing the above-mentioned Ag alloy powder and Ge powder respectively according to the weight percentage of silver alloy powder:germanium powder=97:3, mix them with a Y-type mixer for more than 6 hours until the two are evenly mixed.

[0024] Put the above mixed powder into the powder feeding cylinder of the binder jet metal 3D printing equipment, input the pre-drawn 3D map, and start the printing process: spread a layer of mixed powder on the powder bed and smooth it with a scraper, then use an inkjet The print head selectively sprays the photocura...

Embodiment 2

[0029] The Ag alloy is smelted in the following weight percentages: Ag(95.4%)-Cu(1.1%)-Se(0.8%)-

[0030] Zn(2.0%)-Al(0.7%). Put the above Ag alloy into a graphite crucible, melt it in an intermediate frequency melting furnace, and then use the gas atomization method to make spherical powder, and screen out the fine powder below 500 mesh. Ge powder is a commercially available 5N grade pure germanium powder, which is a brittle powder obtained by mechanical crushing. The fine powder below 500 mesh is screened. After weighing the above-mentioned silver alloy powder and Ge powder respectively according to the weight percentage of silver alloy powder:Ge powder=97:3, mix them with a Y-type mixer for more than 6 hours until the two are evenly mixed.

[0031] Put the above mixed powder into the powder feeding cylinder of the binder jet metal 3D printing equipment, input the pre-drawn 3D map, and start the printing process: spread a layer of mixed powder on the powder bed and smooth i...

[0036] The Ag alloy was smelted in the following weight percentages: Ag(95.4%)-Cu(1.1%)-Se(0.8%)-Zn(2.0%)-Al(0.7%). The above Ag alloy is melted and then made into spherical powder by gas atomization, and the fine powder below 500 mesh is screened out. Ge powder is a commercially available 5N grade pure germanium powder, which is a brittle powder obtained by mechanical crushing. The fine powder below 500 mesh is screened. The above-mentioned silver alloy powder and Ge powder are respectively weighed according to the weight percentage of silver alloy powder:Ge powder=95:5, and then mixed with a Y-type mixer for more than 6 hours until the two are evenly mixed.

[0037] Put the above mixed powder into the powder feeding cylinder of the binder jet metal 3D printing equipment, input the pre-drawn 3D map, and start the printing process: spread a layer of mixed powder on the powder bed and smooth it with a scraper, then use an inkjet The print head selectively sprays the light-curi...

Abstract

The invention belongs to the technical field of metal material additive manufacturing, and particularly relates to a manufacturing process of a silver-germanium infrared health-care ornament, which comprises the following steps: firstly, uniformly mixing Ag alloy powder and Ge powder, and then obtaining a green body of which the shape completely conforms to a pre-designed 3D pattern by adopting an adhesive spraying 3D printing metal forming technology; and degreasing and sintering to obtain a silver-germanium sintered part, and finally carrying out molding post-processing to finally obtain the finished product silver-germanium ornament. The defects that in the germanium-silver alloy machining process, materials are large in brittleness, high in hardness, poor in flexibility and ductility, prone to brittle failure and scrapping and difficult to machine into delicate and exquisite products are overcome; and the 3D printing technology is applied to design and manufacturing of germanium-silver ornaments, one-time forming of complex three-dimensional design products is achieved, the design feasibility of germanium-silver products is greatly widened, and the germanium-silver ornaments have great application value when being applied to health-care products such as ornaments, waistbands, neck bands, bracelets, kneecaps and pillows.

Description

technical field [0001] The invention belongs to the technical field of metal material additive manufacturing, and in particular relates to a manufacturing process for producing silver germanium ornaments with infrared health care function based on a binder jet 3D printing metal forming technology. Background technique [0002] Studies have shown that germanium is a metal that can be used in human health care. The semiconductor properties of germanium make it use the thermal energy of the human body to generate fluctuations when it comes into contact with the body. This fluctuation is used to release negative ions. The current balance of negative ions can promote Microvascular expansion, promote human blood circulation, adjust the ion balance of the human body, reduce fatigue, relieve body pain, and promote the body to restore the balance of positive and negative charges. However, in order for germanium to play its role in health care, metal germanium must be in contact with ...
