In recent years, China's 3D printing industry, which started in the 1990s, has been developing rapidly, and China's huge population has provided a broad market for 3D printing applications. Statistics show that since 2008, the number of 3D printers in China has doubled seven times, and the technology is close to the world's advanced level. However, it should not be ignored that the industrialization of China's 3D printing process is still a large gap with Europe and the United States, the overall application service capacity is still far behind Europe and the United States. In China's 3D printing industry is still in the primary stage of development, Europe and the United States and other developed countries, 3D printing technology has been widely used in space vehicles, automobiles, construction, clothing, and even food, human tissue and organs, etc., especially in some cross-disciplinary areas of the application of more obvious. The reasons for this are: production, learning, research and use of disconnect, although there are already some institutions engaged in 3D printing technology research, but the real 3D printing technology applications and industrialization of the enterprise is not much, a lot of technology only stays in the academic level, do not get a good industrial application; a lot of research and development, innovative products lack of effective combination of market demand, ignored from the prerequisites of the market demand; lack of leading enterprises, core technologies and mature business models. As Luo Jun, executive director of China 3D Printing Technology Industry Alliance, said from the bottom of his heart after visiting Stratasys and 3D Systems: whoever opens the application market first in the future may lead the development of this industry (3D printing). In other words, who has a strong application service capability, who will be able to compete in the 3D printing industry more advantageous and seize the market opportunity.
Unfolding the development scroll of China's 3D printing industry, Beijing Longyuan Automation System Co., Ltd, the holding subsidiary of SANDY Printing Technology Co. As one of the earliest companies in China to research and develop 3D printing technology, Longyuan has been playing the role of practitioner and leader in the industrialization of 3D printing since 1994, when it successfully developed China's first SLS rapid prototyping machine, and has devoted itself to the industrialization of rapid prototyping application and processing services.

In the emerging biomedical field, Longyuan Forming has specially developed AFS-320 rapid prototyping machine, which adopts the selective laser powder sintering method to make solid model with polystyrene powder as raw material, which can be used for the symptoms of zygomaticomandibular bone fiber abnormality hyperplasia in oral medical treatment; and has good therapeutic effect in the clinical treatment of old zygomatico-zygomatic arch comminuted fracture. Through specific CAD software, 3D design of dental base, crown, bridge, hood crown, veneer, and inlay of denture can be realized. In addition, 3D printed heart, kidney, blood vessel models and femoral orthopedic (artificial joints, skulls, pelvic bones) models can be used as effective adjuncts to improve medical success.
In addition, in one of the mainstream application directions of 3D printing in the future, metal 3D printing applications, Longyuan molding is also leading all the way. As early as in 2000, it successfully developed SLS-based rapid casting process for metal parts with complex internal cavity structure, laying the foundation for rapid production of engine-type complex structural parts, and the direct molding technology for metal materials entered the substantial development stage, after which it could manufacture stainless steel and Ni-base alloy steel parts with a density of 100%. in late 2014, under the recommendation of the Strategic Alliance for Powder Metallurgy Innovation, the "Selective Laser Melting (SLM) technology based on SLM", led by Longyuan Molding, has been developed and implemented. At the end of 2014, on the recommendation of the Powder Metallurgy Technology Innovation Strategy Alliance, the project "Digital Metal Parts Forming Machine Based on Selective Laser Melting (SLM) Technology" led by Longyuan Forming was approved as "2014 Zhongguancun Industrial Technology Alliance Major Application Demonstration Project", which became the only project in the field of 3D printing among the approved projects. The project aims to realize the industrialization of SLM forming equipment in aerospace and medical fields through the demonstration application of SLM metal direct forming equipment.
In view of the outstanding performance of Longyuan's 3D printing application service in China, the authoritative media at home and abroad, such as ECONOMIST, the official website of Cheung Kong Graduate School of Business, and MACHINE DESIGN, have repeatedly reported Longyuan in a large space, and called Longyuan as one of China's few non-underestimated 3D printing manufacturing service providers.
