A brief introduction to some 3D printing materials

wallpapers Products 2021-01-12
In order to achieve better results for 3D printing products, it is critical to speed up the development and upgrade of materials supporting 3D printing technology. Generally speaking, the metal powders used in metal 3D printers at home and abroad are: tool steel, stainless steel, martensitic steel, pure titanium and titanium alloys, aluminum alloys, nickel-based alloys, copper-based alloys, cobalt-chromium alloys, etc.
Aluminum alloy
At present, aluminum alloys used in metal 3D printing mainly include AlSi12 and AlSi10Mg. Al-Si 12 is a lightweight additive-manufactured metal powder with good thermal properties and can be used in thin-walled parts. For example, heat exchangers or other auto parts can also be used in aviation industry-level prototypes and parts manufacturing.
Precious metals
The precious metals that can be 3D printed include silver, gold and platinum. These materials are usually relatively soft, high gloss, and low chemical activity. In many cases, their conductivity is also very good. In addition to Concept Laser, Cooksongold is also one of the few companies that provide gold (yellow, white, pink) and platinum 3D printing. These materials are mainly used in jewelry and crafts.
Refractory metal
There are relatively few types of refractory metals, including tungsten, rhenium, niobium, molybdenum, and tantalum. They are known for their high heat resistance, with melting points generally exceeding 2000°C, inactive chemical reactions, high density and high hardness. Among them, tantalum has high corrosion resistance and very good conductivity, which has broad application prospects in the electronics industry. According to the Los Alamos National Laboratory, 60% of this material is used for vacuum furnace parts and electrolytic capacitors. In theory, tantalum can increase the radioactivity of nuclear particles.
The application fields of metal 3D printing materials are quite extensive. In general, aerospace, automobile manufacturing, injection molds, food processing, medical and health, electric power, light metal alloy casting and other fields are included. Of course, the classification of 3D printing metal materials is not limited to these, other printing materials also include rock, cement, paper and so on. With the continuous development of 3D printing materials, processes, and equipment, 3D printing technology will more effectively support my country's steady progress toward a manufacturing power.
