Science and technology are primary productive forces. Once the 3D printing technology came out, it was applied to all walks of life and the entire market was hot. At present, the 3D printing industry has entered the fast-track development and has brought new development opportunities to the manufacturing industry. Then, when 3D printing is combined with automobile manufacturing, what kind of sparks are there?
China's 3D printing
3D printing, which is a kind of rapid prototyping technology, is a technology that builds an object by layer-by-layer printing using a powdery metal or plastic adhesive material based on a digital model file.
It is estimated that the scale of China's 3D printing industry will reach 17.3 billion yuan in 2017, and the average annual compound growth rate will be about 41.36% in the next five years (2017-2021), and the industry scale will reach 69.1 billion yuan in 2021.
Regarding 3D printing, China's unique advantages are reflected in the comprehensive development of the equipment field. From SLA to SLM, LENS technology, bioprinting technology, electron beam welding 3D printing technology and even ultrasonic welding 3D printing technology, China has related strong companies. In commercial operation. In the field of materials, not only does the first-line brand compete with international brands in China, but many domestic companies are also aware that the development of 3D printing technology needs to focus on the unique value of this technology for research and application transformation. They are working in the application field. Positive layout.
In terms of materials, it is understood that in the field of 3D printing materials, China will focus on the needs of the market applications and cutting-edge research, including the modeling and manufacturing of lattices and cells, amorphous metals, gradient alloys, memory alloys, and particle-reinforced high temperatures. The emergence of research benchmarks in fields such as alloys will further drive the soundness of the ecosystem. At the same time, a number of distinctive 3D printing materials companies have emerged in China, including Polymaker in the field of polymer materials, and Shanghai Polymaker has developed PolySher, which can spray special alcohol aerosols on prints to eliminate the print surface. The layered marks significantly increase the surface quality and make the prints as smooth as the injection molded part. Aiming at the technical gaps in the international market, starting from solving the pain points of the market, this has become a clear flow for innovative companies in the field of 3D printing in China.
3D printing lifts global automotive custom production wave
Currently, the application of 3D printing in the automotive field has evolved from a simple conceptual model to a functional prototype toward more functional components and penetrated into the design of core components such as engines. As a major label in the era of Industry 4.0, the development of 3D printing will undoubtedly provide better support for manufacturing production, and its application in automobile manufacturing will also become increasingly widespread.
At the Asia 3D Printing and Additive Manufacturing Show in Asia (TCT Asia) in March this year, Stratasys, the world's leading supplier of 3D printing and additive manufacturing, demonstrated its full range of 3D printer products from desktop to industrial level, including The latest 3D printing technology and automotive solutions.
"Automotive is the first area to be involved in 3D printing technology, and it is also an industry that has received a lot of attention around the world. Stratasys provides solutions for the automotive industry covering the entire life cycle of its manufacturing. Stratasys' 3D printing technology is now widely used. At the automotive design stage, we can meet the needs of the rapid production of current automotive models.Today's Stratasys F123 series is a very diversified product that can meet the actual needs of automotive design, allowing automotive designers and engineers to design automotive designs very easily. The model was printed directly from the CAD file into the final sample." Omer Krieger, president of Stratasys Asia Pacific and Japan, said, "On the other hand, cars require a lot of customized tools to assemble different parts. We work closely with car manufacturers and adopt Lightweight materials are traditionally produced in 3D printing. Compared with traditional tools, 3D printing tools are easier to use. At the same time, we also cooperate with some auto manufacturers to directly print terminal parts."
Ford first tried 3D printing automotive parts
In March, according to TechCrunch, a technology website, Ford Motors began testing 3D printing technology for large-scale production of automotive parts. This new 3D printing technology allows drivers to customize their own car products at a lower price.
Ford Motor Co., the first automaker to use the Stratasys Infinite Build 3D printer, is exploring how to use 3D technology to print large, one-piece automotive parts, such as automotive spoilers, and use it for prototype production and future vehicle manufacturing.
The Stratasys InfiniteBuild system can print automobile parts of virtually any shape or length to produce less-demanding molds, prototype parts, or components in a more cost-effective manner, such as Ford Performance models or custom-made automotive parts. This system may become a breakthrough technology for the automotive industry.
Ellen Lee, Head of Ford Stack Manufacturing Research Technology, said: "With InfiniteBuild technology, we can now print large molds, fixtures and components, allowing us to be more flexible in design iterations. We are excited to be the first to bring Stratasys to The introduction of new technologies will help us to advance the development of large-scale printing technologies that are suitable for automotive applications and needs."
The new 3D printing system is now located at Ford Motor Research and Innovation Center in Dearborn, Michigan, USA.
Currently, the application of 3D printing in the automotive field has evolved from a simple conceptual model to a functional prototype toward more functional components and penetrated into the design of core components such as engines.
At present, GM, Volkswagen and other well-known automobile groups have begun to use 3D printing technology, Ford has adopted this technology on a large scale in the design model stage. The auto makers of FAW, SAIC, and Changan also started to use 3D printing technology for model design and manufacturing.
3D printing automotive parts can be said to be an advancement in 3D printing technology. In the future, 3D printing can bring greater benefits to automobile production, including: production of lighter weight parts, improved fuel efficiency, effective cost control, and customer customization Demand, etc.
