In order to solve the problem of traditional 3D printing is both slow and expensive, 3D printing 2.0 Binder Jetting (Binder Jetting/3DP, hereinafter referred to as BJ) process has emerged. Compared to 3D printing 1.0, such as PBF, DED and other metal additive manufacturing process is the use of "point scanning" technology, the existence of processing efficiency is low, the cost is several times that of the traditional manufacturing technology, it is difficult to realize the large-scale industrialization of the application of the "line scanning" technology, the 3D printing 2.0 Binder Jetting (BJ) process has emerged. 3D printing 2.0 binder jetting BJ process using "line scanning" technology is a high-efficiency, high-precision additive manufacturing technology, which follows the traditional powder metallurgy industry's material system and sintering process, low cost, high degree of standardization of materials, can provide high-efficiency, high-quality, low-cost metal additive manufacturing solutions for the industrial session can be applied to the production line, for the large-scale application of 3D printing technology to lay a solid foundation. solid foundation. It is expected that 3D printing 2.0 will bring breakthrough and continuous growth for the 3D printing industry.

Internationally, Desktop Metal, HP, Digital Metal, GE and other global technology companies are optimistic about the market potential of BJ metal technology, in the past five years have completed the development of BJ metal technology, and achieved a certain degree of industrialization applications. As a large manufacturing country, China's market demand for BJ metal technology is even more urgent, especially from the MIM (Metal Injection Molding) industry for rapid prototyping and small and medium-sized mass production. Against this background, domestic BJ metal technology has developed rapidly in recent years. In fact, as early as 1994, Dr. Zong Guisheng, the founder of Beijing Longyuan Automatic Forming System Co., Ltd (a subsidiary of SANDI Technology, hereinafter referred to as "Longyuan Forming"), put forward the concept of "line scanning" and declared "Since 2018, through the technological innovation of the postdoctoral team at the postdoctoral workstation and the engineering innovation of the R&D team, Longyuan has successfully developed and produced a series of BJ equipment and 5 series of adhesives applicable to more than 20 materials. of 5 series of bonding agents, and put them on the market.

Based on the synergistic innovation system of the company's Guoqian Science and Technology Research Institute, post-doctoral workstation and product development team, and the foundation of nearly 30 years of development of additive manufacturing equipment, Longyuan Molding has independently mastered a number of key technologies related to the equipment, materials and processes of the binder injection molding technology, and has completed the development of R&D R-series and production P-series series of equipments and the development of systematic material processes, such as iron-based materials, non-ferrous metals, high temperature alloys, refractory metals, ceramic materials, inorganic salts, polymer materials and food materials. Alloys, refractory metals, ceramic materials, inorganic salts, polymer materials, food materials and other systematic material technology development.

It can be seen that the market growth rate of 3D printing is quite high, the whole industry scale is growing year by year, but compared with other industries, 3D printing is still a small industry. The reason for this is that the main constraints on the printing efficiency of 3D printing and material costs. For example, based on "point scanning" laser powder bed molten metal 3D printing technology, its aerospace, automotive, military, molds, medical and other fields of small quantities of precision metal parts manufacturing has many applications, but also compared to traditional manufacturing technology has more advantages, but for most industrial users, 3D printing to get a larger scale industrialized Application, there is an urgent need to solve the "slow and expensive" problem.

Binder Jetting (Binder Jetting/3DP, hereinafter referred to as BJ) is a high-efficiency, low-cost "line scanning" 3D printing technology, as early as 1993 was born in the United States at the Massachusetts Institute of Technology, due to the higher threshold of the process, the industry chain is much longer, the development process of the BJ technology lags behind the "dot scan" laser 3D printing technology. "Point scanning" laser 3D printing technology, but by virtue of efficiency and cost advantages, BJ technology is full of energy. In recent years, with a series of technological breakthroughs in the field of BJ, especially the successful development of BJ metal, once again by the industry's widespread attention, known as "Additive 2.0" technology. According to a SmarTech report, by 2030, indirect metal printing technologies such as binder jet 3D printing will realize an output value of 54 billion U.S. dollars (about 350 billion yuan).

Internationally, Desktop Metal, HP, Digital Metal and other companies in the past five years have completed the technical development of BJ metal technology, to achieve a certain degree of industrialization and application. Domestic BJ technology started later, but as a manufacturing country, China's market demand for BJ technology is more urgent, especially from the MIM (Metal Injection Molding) industry for rapid prototyping and small and medium-sized mass production needs. In this context, the rapid development of domestic BJ technology. It is understood that there are several domestic enterprises to BJ as a research project, of which, Beijing Longyuan Automatic Molding System Co., Ltd. (SANDI's subsidiary companies, hereinafter referred to as "Longyuan molding") has been put on the market equipment.

Longyuan Molding Company, a leading 3D printing technology company in China, completed the development of BJ metal technology and launched AFS-J120 and AFS-J380 equipment during 2018-2020. The equipments are built with integrated small particle size (5~15μm) low-fluidity powder precise feeding system, new powder spreading roller pressure system and high-precision inkjet printing system (1200dpi), which can realize ±0.1mm printing precision, >3600cc/h printing speed and >55% green blank density, and the relevant technical indexes have reached the international advanced level.

On the basis of the equipment, Longyuan Forming has successfully developed a series of BJ-specific binder formulations, which are suitable for more than 20 kinds of matrix materials, such as iron-based alloys, light metal alloys, organic glass, ceramics and so on. The team has conducted systematic research and analysis on the physical and chemical properties of the binder and the interaction between the binder and the powder, among which the water-based binder has the characteristics of green environmental protection, sintering low carbon and oxygen residue, etc., which has a good application effect. The degreasing and sintering process is a necessary back-end process to complete the manufacturing of BJ metals. The degreasing and sintering properties of the relevant BJ metal materials of Longyuan Forming have reached the international material standards of the MIM industry, and have the conditions for industrialization and application.

Binder jet metal 3D printing technology is considered to be one of the best ways to realize mass production of metal 3D printing due to its high printing efficiency, low material cost, cost-effective equipment, no additional support, and suitability for batch production, etc. The layout of Longyuan Forming in this field is also the implementation of its development concept of "platform + ecology" based on the core technology of 3D printing. The layout of Longyuan molding in this field is also based on the core technology of 3D printing, to create a "platform + ecological" development concept of practice.
