[China Aluminum] In the just-concluded Rio Olympic Games, athletes from all over the world are undoubtedly the focus of the Olympic Games. But in this Olympic Games, in addition to athletes, the number of 3D printing technology is higher. Such as 3D printing running shoes, 3D printed prosthetic limbs, 3D racing wheelchairs, 3D printing sportswear, etc., one by one. Going out of the forefront of practical science and technology, such as the Olympic Games, seems to indicate that 3D printing technology will enter our lives in the near future.
In the aluminum industry, some of the industry giants in the world are also seeing the broad prospects of 3D printing technology and have announced their commitment to 3D printing. Recently, RUSAL announced that it has signed an agreement with SAUER GmbH, a member company of the world's largest RUSAL and DMGMORI, a global manufacturer of large-scale mixed-laminated manufacturing machines. Aluminum and aluminum alloy industrial 3D printing technology. The technology will be able to print aluminum parts for customers in the machine production, aerospace and automotive industries, which indicates that this world aluminum giant will be the industry leader in 3D printing.
Americans also felt the arrival of the wave of 3D printing. Researchers at the Open Sustainability Technology (MOST) Laboratory at the Michigan Technological University in the United States launched a project to explore the common applications of aluminum alloys in 3D printing. Paper on the project's "GMAW-based 3D metal printing technology in the use of common aluminum welding alloy as a raw material when the structural properties of relations." The beginning of this research will be a good start for aluminum alloy 3D printing to life.
Then, what is the "marriage" between 3D printing and aluminum?
How does a 3D printer "print"?
3D printer, also known as 3D printer (3DP), is a kind of cumulative manufacturing technology, ie, a machine for rapid prototyping technology. It is a digital model file based on the use of special wax materials, powdered metals or plastics, etc. can be bonded Materials, to create three-dimensional objects by printing a layer of adhesive material. At this stage, three-dimensional printers are used to make products. Layer-by-layer printing techniques to construct objects.
The principle of a 3D printer is to put data and raw materials into a 3D printer. The machine will make products layer by layer according to the program. The big difference between a 3D printer and a conventional printer is that the ink it uses is a real raw material. There are a variety of stacked thin layers. The types of media that can be used for printing vary from a wide variety of plastics to metals and ceramics. Rubber materials. Some printers can also combine different media so that printed objects are hard and soft on the other.
Will 3D Printing Transform the Aluminum Industry?
3D printing has brought about a worldwide manufacturing revolution. It used to be that the design of parts depends entirely on whether or not the production process can be realized. The emergence of 3D printers will overturn this production idea, which will allow enterprises to no longer consider production when producing parts. Process problems, any complex shape design can be achieved through a 3D printer. This will greatly improve the precision of precision instrument parts, making it more sophisticated and smooth.
This important feature is reflected in the aluminum industry is the use of custom-made 3D printers for the processing of aluminum parts, and can control the accuracy to the micron level. This feature is critical to the refinement of aluminum alloy parts for various types of machinery. Therefore, Audi has specifically purchased a number of 3D printers, and stated that the ultimate goal is to “achieve small-volume products optimized through topology and process optimization. Efficient production."
The Russian scientific community and the business community are also working together to enhance the country’s competitiveness in the global 3D printing market. Spacecraft is an important project, especially the manufacture of satellites. The project to manufacture high-quality satellite 3D printers is under development and is supported by the Russian Federal Space Agency Roscosmos (National Space Company) and other space-related Russian companies and universities.
Not long ago, Sirius, a Russian-centered Russian education center in Sochi, Russia, briefed Russian President Vladimir Putin on a sample of 3D printers. At present, the model has been adjusted and applied to the operation of the International Space Station to produce suitable satellites.
Closer to home, Joris Laarman Labs has launched a furniture made from 3D printing - "gradient aluminum chairs." This chair is made of a small amount of molten aluminum alloy combined with 3D printing technology. It has a complex spatial structure and aesthetics, and elaborates the concept of furniture design in the digital age. Let's enjoy the charm of this 3D printed aluminum chair.
