Time as a scroll, struggle as a pen, every solid footprint is a vivid footnote that defines the breakthrough.

When the wheel of time quietly crossed 2025, we stood at the threshold of the old and the new and looked back at the resounding footprints that SANDI Technology had walked. This year, we took hardcore innovation as ink and digital intelligence as scroll, and waved a magnificent picture of industrial upgrading on the canvas of the times. When the first ray of dawn of 2026 is about to sprinkle the earth, we are full of gratitude and pride, and harbor unlimited expectations for the future.

2025: Innovation Leads, Breaks the Waves

Compacting the product matrix and constructing a full-series layoutIn 2025, SANDEK has completed the series layout of full-size equipment from millimeter scale to meter scale, and realized the comprehensive coverage of 3DP sand printing, BJ binder jet metal/ceramic printing, SLS selective laser sintering and SLM selective laser melting, and other intelligent equipments. It is especially worth mentioning that our 4-meter super-large-size 3DP casting sand printer 3DPTEK-J4000 has been awarded the title of 2025 Additive Manufacturing Quality Product, which has become a solid base to support the innovation and development of customers in various fields.

Refinement of the technical core, showing the bottom of innovationThis year, we not only realized the stable mass production of large-size sand printing equipment, but also innovatively launched the "flexible area molding technology without sand box", which provides a new solution to solve the problem of large and complex casting manufacturing. This year, we not only realized the stable mass production of large-size sand printing equipment, but also innovatively launched the "no sand box flexible area molding technology", which provides a brand new solution for solving the problem of manufacturing large and complex castings. In the field of high-end heat dissipation, we successfully realized the precision molding of high thermal conductivity composite materials, and the core performance of our products exceeded the international standard of MIM, demonstrating our excellent technical strength.

Promote global layout and internal and external synergiesIn 2025, the domestic business of SANDI Technology has realized leapfrog growth, with significant year-on-year growth in performance scale, widely serving more than 500 high-quality customers in aerospace, power and energy. Overseas market is also soaring, business in more than 30 countries and regions around the world, overseas revenue accounted for a significant breakthrough. Our equipment is exported to Italy, Turkey, Spain, South Korea and other key markets in Europe and Asia, the globalization of the operating system is increasingly perfect.

Expanding the business ecosystem and opening up new frontiersIn August, we successfully acquired Shenzhen Shuanglong Dental Research Technology Co., Ltd, which is not only an important layout of the digital dental field, but also obtains the mature channels covering more than 30 countries and international certification qualification, which lays a solid foundation for entering the high-end dental market.

Strategic Financing Landed, Strengthening the Roots of DevelopmentIn 2025, we successfully completed two strategic investments from the Beijing New Materials Industry Fund and SINOMACH Industry Fund. These funds will be used for the pre-investment of binder jet equipment (BJ/3DP), ceramic printing process expansion, copper diamond chip heat sink capacity construction, accelerated product overseas and talent construction, further consolidating our leading position in the binder jet 3D printing field.

2026: A journey of 10,000 miles, a cloud of high sails

In the new year, SANDI will continue to promote the "1-2-N" development strategy, that is, to take one set of 3D printing technology as the core, plowing 3D casting and 3D powder metallurgy two major solutions, expanding N application scenarios, to build a richer industrial ecology.

Consolidate technological leadership and strengthen the innovation systemAs a domestic enterprise that simultaneously masters four core 3D printing technologies, namely SLS, SLM, 3DP and BJ, we will continue to utilize the advantages of "Trinity" innovation system. As a domestic enterprise that simultaneously masters the four core 3D printing technologies of SLS, SLM, 3DP and BJ, we will continue to take advantage of the "Trinity" innovation system and integrate the resources of Guoqian Science and Technology Research Institute, postdoctoral workstation and enterprise R&D team to continue to promote technological innovation and maintain the leading position in the industry.

Upgrade casting ecology and expand application areas. Through the 8 3D Smart Manufacturing bases laid out in China, in 2026 we will focus on promoting the large-scale application of 3D printing in high-voltage electrical and rail transportation fields, and reshaping the traditional casting ecology through new construction, expansion and mergers and acquisitions to realize large-scale application production and delivery.

Deepen powder metallurgy and implement differentiation strategyBJ Technology is a leading manufacturer of AI chip thermal management equipment. Relying on the advantages of BJ technology of "high efficiency, low cost, no thermal stress", we will implement differentiated equipment strategy in the field of AI chip thermal management, providing customized solutions for research institutes and industrial users. Suzhou SANDI Precision will focus on the field of binder jetting 3D printing copper diamond heat dissipation, and realize the batch delivery of applications in this field.

Expanding Digital Healthcare, Perfecting Precision Manufacturing. On the basis of having the first 3D printed titanium alloy hearing aid medical device registration certificate in China, through the merger and acquisition of Shenzhen Shuanglong Dental Research, we will further expand the 3D printed orthopedic application field, improve the layout of precision medicine, and contribute more power to the cause of human health.

Build an industrial Internet platform to accelerate digital transformation. In the new year, we will focus on building the 3D Smart Manufacturing Industrial Internet Platform, comprehensively improving the company's digital management capabilities, and at the same time making efforts in going overseas and unmanned factory construction to create a new paradigm of future-oriented intelligent manufacturing.

The heart is as solid as a rock and the mission is as strong as ever

Pragmatism, innovation, synergy, growth - these four keywords are deeply imprinted in the pursuit of values and development concepts of SANDY TECHNOLOGY.

From 1994, when we successfully developed the first commercialized industrial-grade 3D printer with independent intellectual property rights in China to the present, SANDI Technology has always been adhering to the mission of "Starting from 3D printing, upgrading manufacturing with digital technology". With more than 30 years of innovation, we have witnessed and participated in the wave of digital transformation of China's manufacturing industry.

Looking forward to 2026, we will continue to work hand in hand with our global partners to promote the integration of 3D printing technology into thousands of industries with a more open attitude, a more innovative spirit and more pragmatic actions, injecting new kinetic energy into the high-quality development of the manufacturing industry, and contributing more "SANDI Solutions" to the intelligent manufacturing in China and even in the world.

Thank you for the trust and support of every customer, partner and employee. Let's work hand in hand to meet the excitement and splendor of 2026! Happy New Year!
