What is 3D printing?
3D printing is named 3DP, also known as additive manufacturing. It is a digital model file based on the use of powdered metal or plastic bonding materials, through layer by layer printing. The technique to construct objects.
3D printing technology, also named as "additional manufacturing" in the related field, is also called incremental manufacturing in a particular range.
One of the widely accepted definitions is the use of a three-bit data model to achieve layer-by-layer fabrication of materials using a specific technical approach. In principle, the data is restored based on the three-dimensional physical robust model, and the material combination technology realizes the shaping of the components.
Compared with traditional manufacturing technology, 3D printing technology has apparent advantages in data model manufacturing. Its outstanding performance is the digital manufacturing features concentrated in the manufacturing process and the layered manufacturing features highlighted in the manufacturing process. And the focused execution of the stacked manufacturing features reflected in the manufacturing process. Besides, 3D printing technology also realizes rapid direct construction due to its 3D data modeling in data processing mode. This feature makes 3D printing technology break through the constraints of the molds in the manufacturing process and realizes the direct manufacturing of one molding.
3D printing powder:
metal 3D printing materials mainly include titanium-based alloys, nickel-based alloys, aluminum-based alloys, iron-based alloys, and cobalt-based alloys. Among them, Luoyang Tongrun Nano Technology Co., Ltd., which produces 3D printing powder, is mainly engaged in research and development and production of various kinds. Metal 3D printing materials have released more than 20 types of metal 3D printing standard powder products to users all over the world. For the first time, the metal powder has the excellent performance of "flowing like water" and competes with famous European and American materials suppliers.
As a rising star metal 3D printing material company, Luoyang Tongrun has used four world-class 3D printing powder technology in just two years to develop a special printing parameter package. The quality is stable, and the performance is excellent. It meets or exceeds the performance of imported similar products. It can directly replace imported powder, effectively solving bottlenecks such as ambiguous powder import, high price, few types, and long cycle. In terms of quality, the SLM process uses 15-45 micron Ti6Al4V titanium alloy powder as an example. The Hall flow rate of Luoyang Haorun products is ≤35s/50g, and it exhibits excellent comprehensive mechanical properties. Based on the optimization of a new titanium alloy material composition, powder Preparation and gas content control, effectively help users solve the problem of imported powder printing cracking technology, achieve replacement, and significantly reduce the project cycle.
The company has successfully developed nearly 20 kinds of titanium alloys, nickel-based alloys, cobalt-chromium alloys, stainless steels, die steels, aluminum alloys and other standard grade powder materials, including titanium-aluminum intermetallic compounds, nickel-titanium shape memory alloys, high-strength aluminum alloys, A large number of internationally advanced 3D printing materials, such as high-entropy alloys, amorphous alloys, and graphene reinforced composite powders, have compiled more than 20 kinds of metal standards for laser melting metal powder materials, and participated in the preparation and review of a number of additive manufacturing aviation industry standards. And national standards.
It will bring a new experience to the global 3D printing user's powder selection and materials, fully demonstrating the technical standards and confidence of China's 3D printing new materials companies, and will surely drive a batch of new technologies and new products to the international market, and accelerate development of new materials for 3D printing.
3D printing applications in manufacturing:
Digital manufacturing technology will gradually change the existing models of traditional centralized mass production to achieve a more distributed model. Traditional manufacturing models focus on centralized, low-cost mass production to reduce product costs and gain labor advantages, while distributed models rely on smaller, flexible, and scalable production capabilities connected to digital networks. The distributed manufacturing model reduces the length, complexity, and cost of the supply chain and allows for rapid customization of products and enhanced local market responsiveness.
Frank Thurston, Ernst & Young's global additive manufacturing director, said: "From a cost and cost perspective, 3D printing is still not a substitute for traditional mass production, but in redesigning parts for additional functionality or integrating a set of parts. In terms of a more complex part, 3D printing has a unique advantage to promote tailor-made parts or applications further."
3D printing technology is the heart of distributed manufacturing. The range of 3D printable materials continues to expand, not only for plastics but also for metals, resins, and ceramics. 3D printing technology enables more complex geometries than traditional molding, machining, and casting processes. Although additive manufacturing technology has been widely used for prototyping, a survey in 2019 reported that more and more manufacturers have begun to use 3D printing for full production. The ability to directly prototype 3D printed prototypes or parts from digital files has spawned a new Manufacturing-as-a-Service (MaaS) business model that enables manufacturers to expand on-demand manufacturing services to achieve operational flexibility and reduce business costs.
3D printing will not replace existing traditional manufacturing techniques, but it will be a new process that goes hand-in-hand with conventional subtractive manufacturing methods. Flexible product customization capabilities are better suited to changing consumer needs, lower inventory and logistics cost requirements, and closer production capacity and shorter lead times. Distributed production environments offer some of the benefits.
Manufacturing upgrades and the advancement of Industry Upgrade are a system-level project, and a series of new technologies such as AI, industrial Internet of Things IIoT, big data, 3D printing, new materials, new batteries, nanotechnology, and molecular manufacturing will gradually Mature, market-oriented, entering factories and workshops. Traditional construction will not disappear, but more efficiently, cleaner, sustainable, and on-demand production of the goods we need.
