Introduction of 3D printing and 3D printing powder
3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses 3D Printing Powder such as powdered metal or plastic and other bondable powder to construct objects based on digital model files by printing layer by layer.
3D printing manufacturing technology is mainly composed of 3 key elements:
1. Precise 3D design
2. Forming equipment;
3. Powder that meet product performance and molding process.
Since 3D printing manufacturing technology has completely changed the methods and principles of the traditional manufacturing industry, and is a subversion of the traditional manufacturing mode, 3D printing powder have become the main bottleneck restricting the development of 3D printing, as well as the key points and difficulties of 3D printing breakthrough innovation. Only by developing more new powder can the application fields of 3D printing technology be expanded. At present, 3D printing powder mainly include polymer powder, metal powder, ceramic powder and composite powder.
Metal 3D printing powder
1) Stainless steel
Stainless steel is the cheapest metal printing material. The surface of high-strength stainless steel products printed by 3D is slightly rough and there are pits. Stainless steel has a variety of different glossy and frosted surfaces, and is often used for 3D printing of jewelry, functional components and small sculptures.
2) High temperature alloy
High-temperature alloys have become the main 3D printing powder used in the aviation industry due to their high strength, stable chemical properties, difficulty in forming and processing, and high cost of traditional processing techniques. With the long-term research and further development of 3D printing technology, aircraft parts manufactured by 3D printing have been widely used due to their processing man-hours and cost advantages.
Titanium alloy parts manufactured by 3D printing technology have very high strength and precise dimensions. The smallest size that can be produced can reach 1mm, and the mechanical properties of the parts are better than the forging process. Titanium powder consumables will have broad application prospects in 3D printing automobiles, aerospace and defense industries.
2) Magnesium aluminum alloy
Magnesium-aluminum alloys have been widely used in the light-weight requirements of the manufacturing industry due to their superior performance of light weight and high strength. In 3D printing technology, it has become the preferred material of all major manufacturers without exception.
Gallium (Ga) is mainly used as a 3D printing material for liquid metal alloys. It has metal conductivity and its viscosity is similar to water. Unlike mercury (Hg), gallium is neither toxic nor evaporates. Gallium can be used in flexible and stretchable electronic products, and liquid metal has been used in flexible telescopic parts of deformable antennas, soft storage devices, super-stretch wires and soft optical parts.
3) Gallium-Indium alloy
Scientists used a liquid metal alloy of gallium (Ga) and indium (In) to create a three-dimensional free-standing structure at room temperature through 3D printing technology. This miracle was born thanks to the gallium-indium alloy in the air with oxygen The reaction forms an oxide film that can maintain the shape of the part. This technology is used to connect electronic components in 3D printing.
4) Rare and precious metals
3D printed products are becoming more and more influential in the fashion industry. Jewelry designers around the world seem to benefit the most from 3D printing rapid prototyping technology as a powerful creative industry that can easily replace other manufacturing methods. In the field of jewelry 3D printing powder, gold, sterling silver, brass, etc. are commonly used.
5) Composite powder
The Arevo Laboratory in Silicon Valley, USA, 3D printed a high-strength carbon fiber reinforced composite material. Compared with traditional extrusion or injection molding methods, 3D printing can be used to precisely control the orientation of carbon fibers to optimize specific mechanical, electrical and thermal properties, and its comprehensive properties can be strictly set.
Since 3D printed composite parts can only be manufactured one layer at a time, each layer can achieve any desired fiber orientation. The complex shape parts printed in combination with reinforced polymer powder have excellent high temperature and chemical resistance.
