How far is 3D printing from large-scale application

as one of the key technologies of intelligent manufacturing, 3D printing can quickly produce various forms of structural organizations, and its great commercial value is gradually being reflected, and is expected to finally explode a huge market opportunity. Last year, the global 3D printing market developed rapidly, especially in Europe, where the market momentum was strong. IDC, an international data company, predicted optimistically that the European 3D printing revenue would reach $7.4 billion in 2022, including 3D printers, materials, software and related services. During this period, the compound annual growth rate would reach 14.4%, which is also a common mechanical testing equipment%

using 3D printing has many advantages. It can realize mass customization and print different types of products. At the same time, it can reduce costs and recycle excess printer powder. Only a small number of tools are needed to complete product molding. 3D printers can replace some other production tools and directly form by stacking and bonding. Especially in the product development stage, proofing requires a certain amount of time to be processed by the processor, and the sample may only be used once. It is very expensive to specially open the mold to make a sample. 3D printing meets the personalized customization of a single batch, which can minimize the cost. In terms of technology, fused deposition molding (FDM) is the core technology of 3D printing development. At first, ordinary heating rods were used to solidify and form after extrusion through the print head. Up to now, there have been many advanced melting technologies, such as multi jet melting, laser sintering melting technology, EBM electron beam melting, etc., which make 3D printing more applicable. On this basis, a temporary plant quarantine decree material aimed at China has been signed

in terms of 3D printing materials, from plastic molding in the past to resin, graphite, ceramics, metals and organic biomaterials, the continuous breakthroughs in new material technology have further expanded the application scope of 3D printing

with the development of melting technology and materials, it is no longer a problem for 3D printing to expand to various fields. At present, in the discrete manufacturing industry, the automotive and aerospace industry is the largest application market of 3D printing. Automotive manufacturers began to use 3D printing technology to manufacture automotive parts, which replaced stamping machines, injection molding machines and other equipment. 3D printing can support more customized services and help aviation manufacturers realize personalized manufacturing of engine blades to seats

in addition, it is expected that the medical industry will further develop in the next few years, such as printing biological tissues, organs, bones and other objects. Health care providers are expected to increase the expenditure on 3D printing, with a CAGR of 19.5%. In addition to industrial and medical directions, 3D printing is also used in after-sales parts and architectural design. The huge space hidden by 3D printing will soon be released
