(hereinafter referred to as "SANDI") announced the completion of the acquisition of Shenzhen Shuanglong Dental Research Technology Co. This acquisition is a reinforcement of the important application of 3D printing in the field of rehabilitation and medical treatment. SANDI has formed a unique "12N" strategy in the field of 3D printing, i.e. 1 set of 3D printing machines, 1 set of 3D printing machines, 1 set of 3D printing machines and 1 set of 3D printing machines.3D printing technology, 2 solutions (3D Castingcap (a poem)3D Powder Metallurgy), N application scenarios.

Shuanglong Dental Research focuses on providing high-end customized denture solutions for the global market, mainly focusing on all-ceramic restorations, implant restorations and 3D printed removable dentures, serving high-end clinics and implant centers. The company holds EU CE, US FDA and China Class II medical device certificates, and its products are exported to more than 30 countries and regions around the world, such as America, Europe, Australia and Southeast Asia. The company has a team of senior technicians with more than 20 years of experience and a professional multi-lingual customer service team. Relying on the digital service platform, the company supports efficient STL/CAD cloud docking and has established an internationalized delivery network covering DHL/UPS.
 
Data show that the global dental 3D printing market size has reached 5.2 billion dollars in 2024, and is expected to exceed 9.6 billion dollars in 2033. The strong combination of SANDI and Ssangyong Dental Research not only combines SANDI's core technology advantages in 3D printing intelligent equipment and material process with Ssangyong Dental Research's channel network, production capacity and dental restoration technology in the global high-end denture market, but also is a deep integration of the two sides in technological innovation and global market development. Through this merger and acquisition, SANDI will be able to quickly access the mature customer base covering high-end markets in Europe and the United States, accelerating the global landing of its dental 3D printing solutions; at the same time, Ssangyong Dental Research will also get stronger technical empowerment, significantly improve product innovation, production efficiency and global delivery capacity, and jointly expand the incremental market of directly printed permanent restorations, orthodontic appliances and so on.

This merger and acquisition reflects the unremitting efforts and remarkable achievements of SANDI Technology in technology leadership and deep application cultivation.

I. Leading Technology: Building a "Trinity" Innovation System

As a national high-tech enterprise, a "small giant" enterprise and a typical application scenario supplier of additive manufacturing of the Ministry of Industry and Information Technology (MIIT), SANDI has a profound technical background. The company is the only service provider in China that has mastered the four core 3D printing technologies of Selective Laser Sintering (SLS), Selective Laser Melting (SLM), 3D Sand Printing (3DP) and Binder Jet (BJ).
 
Its innovation system consists of "Guoqian Science and Technology Research Institute" (gathering more than 40 national experts/doctoral scholars, focusing on original innovation), postdoctoral research station (focusing on common technology development) and enterprise R&D team (responsible for the transformation of the results) "three in one". The company has led or participated in the completion of six major special projects of the Ministry of Science and Technology, and has declared nearly 300 intellectual property rights, including 59 authorized invention patents.
 
Second, application deep plowing: the whole chain layout to drive growth

Focusing on industrial-grade additive manufacturing and aiming at "improving efficiency, reducing costs and improving quality", SANDI has built a complete industrial chain covering equipment R&D and production, material R&D and production, process technology support and rapid finished product manufacturing. Headquartered in Beijing, the company has subsidiaries in many places across the country, with more than 120,000 square meters of space (of which more than 60,000 square meters are self-holding), and has established a full chain, multi-materials, full-size domestic rapid manufacturing delivery system and international service network, and its core application areas include:
 
 1.3D casting: reshaping the traditional casting ecology
Through M&A integration and self-construction, SANDI has laid out 8 3D printing rapid manufacturing bases in China, forming an ecological network. Based on the integrated process of "process design-3D printing-casting-machining-inspection", the company provides rapid prototyping, small-lot multi-species and complex metal parts manufacturing services. Using self-developed 3DP sand printing and SLS series equipment, the company provides 3DP sand casting, SLS sand casting, 3DP/SLS precision casting and other complete solutions, serving more than 500 customers in aerospace, automotive, energy, etc., with materials covering aluminum, copper, iron, steel, magnesium, high temperature alloys, titanium alloys, etc. The company has also established an ecological network based on the integrated process of "process design - casting - machining - testing".
 
 2.3D Powder Metallurgy: Implementing a Differentiated Equipment Strategy
Relying on the advantages of BJ technology "high efficiency, low cost, no thermal stress" and deep technical reserves (including the development of high-performance water-solvent-based binder systems and more than 20 process formulations), SANDI has implemented a differentiated equipment strategy in the field of thermal management of AI chips: for scientific research/chip design enterprises: desktop research equipment J160R for rapid prototyping and thermal design verification; for liquid-cooled server manufacturers: providing integrated industrial solutions (J400P/J800P equipment + special powders/binders + process kits), which can shorten customers' process development cycle by more than 60%.
 
 3. Rehabilitation medical customization: precise digital manufacturing
The company empowers rehabilitation medical care with 3D printing technology, providing products and services such as hearing aids, digital dentistry (meaning teeth), orthotics and prosthetics. We have the first 3D printing titanium alloy hearing aid medical device registration certificate in China. Through the merger and acquisition of Shenzhen Shuanglong Dental Research, we have perfected the high-end customized digital dental solutions to serve clinics and implant centers around the world.
 
Dr. Zong Guisheng, Chairman of SANDI Technology, said, "The merger and acquisition of Shuanglong Dental Research is an important step in the strategic development of SANDI Technology, which not only provides us with a new growth point in the 3D medical field, but is also an important addition to the empowerment of rehabilitation medical care by 3D digital technology. We look forward to this cooperation to bring more innovations to both parties and jointly promote the industrialization of 3D printing technology in the field of rehabilitation and medical treatment."
 
Shuanglong Dental Research's founder, Peng Huihua, and general manager, Chen Long, both agreed: "After joining the SANTI Technology ecosystem, we are able to leverage SANTI Technology's digital manufacturing technology and material and process advantages to further enhance the design and manufacturing capabilities and delivery speed of high-end dental products, and better respond to users' needs for efficient chairside solutions."
