Jingyan Technology Obtains Patent for 3D Capillary Wick Heat Sink, Enhancing Cooling with 3D-Printed Structure

2026-06-23

Jingyan Technology (300709) has been granted a patent for 'A Method for Preparing a Three-Dimensional Capillary Wick Structure Heat Sink' (Patent No. CN202311598940.0). This patent uses 3D printing to form a three-dimensional metal capillary structure, enabling coolant to flow along the X, Y, and Z axes, significantly improving heat dissipation compared to traditional 2D copper mesh or copper powder structures. Additionally, multilayer metal capillary structures made of aluminum alloy or stainless steel replace conventional pure copper mesh, substantially reducing costs. In 2025, the company's R&D investment reached RMB 289 million, a year-on-year increase of 62.08%. Since the beginning of this year, it has received 15 new patent grants, a 50% increase compared to the same period last year.

Titomic Secures U.S. Defense Component Order from EOS Defense Systems, Delivered Within One Week

Titomic's U.S. subsidiary has received an order from EOS Defense Systems USA to supply critical components for its U.S. defense production program, with delivery completed within one week. The order value was not disclosed. The order involves the rapid re-manufacturing of critical components using cold spray additive manufacturing. Cold spray is a solid-state deposition process used to fabricate and repair metal parts without melting the material. Rapid re-manufacturing and short-lead-time delivery of defense spare parts are typical applications of cold spray technology. This order validates the practical value of cold spray in the defense supply chain. Value for powder buyers: ① Demand for metal powders used in cold spray (aluminum, copper, titanium and their alloys) is linked to the defense repair market—relevant grades and particle sizes should be monitored. ② Domestic cold spray equipment and powder suppliers may find opportunities in the military repair sector. ③ As the order value was not disclosed, ongoing monitoring is needed to determine whether sustained orders will follow, which would clarify the scale of powder demand.

TRUMPF Acquires Cutlite Penta to Expand Laser Tube Cutting Product Line

TRUMPF has announced the acquisition of Italian laser cutting equipment manufacturer Cutlite Penta to expand its laser tube cutting product line. The acquisition amount was not disclosed. Cutlite Penta specializes in customized large-format, high-power laser cutting and ultra-long tube cutting equipment, with 34 years of industry experience. The company will retain its independent brand, manufacturing, and sales operations after the acquisition. TRUMPF, a manufacturer of lasers and laser processing equipment, also supplies lasers for metal additive manufacturing systems. The acquisition will broaden TRUMPF's product coverage in the laser processing market. As a core supplier of lasers for metal AM equipment, the company's expanded scale is expected to enhance supply stability and cost control of laser sources. Value for powder buyers: (1) Laser costs account for a significant portion of metal AM equipment expenses, and changes in the upstream supply landscape indirectly affect equipment pricing, which in turn impacts printing service costs. (2) The direct impact on the powder side is limited, making this primarily a supply chain dynamic. (3) It is worth monitoring TRUMPF's future investment in its additive manufacturing business line, as laser technology iterations could drive improvements in equipment process capabilities.

America Makes Announces 2026 Ambassadors and Outstanding Collaboration Award

America Makes has announced its nine ambassadors for 2026 and awarded the 2026 Outstanding Collaboration Award to Brett Conner, Chief Manufacturing Officer of SME. The organization also elected a new executive committee during the same period. The nine ambassadors, drawn from government, industry, and academia, represent sectors including defense, aerospace, energy, and equipment research, and will contribute to the promotion of additive manufacturing technologies and industry collaboration. America Makes is the U.S. national innovation institute for additive manufacturing, headquartered in Youngstown, Ohio. America Makes' membership and ambassador network serve as a key channel for U.S. additive manufacturing policy, standards, and program funding. Its annual project selections reflect the direction of U.S. industry resource investment. Value for powder buyers: ① Monitor America Makes' annual projects and challenge themes (e.g., collaborations with the U.S. Department of Defense's OIB), as these directions often drive demand for specific materials and processes. ② Companies doing business in the U.S. can leverage the ambassador network to gain insight into technology promotion priorities. ③ Evolutions in the U.S. standards system may impact powder certification requirements for exported products, so ongoing tracking is essential.
