Zhuque-3 Static Fire Test Completed, LandSpace’s STAR Market IPO Resumes Review
On June 29, LandSpace Technology Corporation achieved a dual milestone. The company’s Zhuque-3 reusable Y2 launch vehicle successfully completed a static fire test at the Dongfeng Commercial Aerospace Innovation Zone, with all systems operating normally—confirming the rocket has met all launch requirements. The Zhuque-3 is a new-generation, low-cost, high-payload, high-frequency reusable liquid oxygen methane launch vehicle developed by LandSpace for large-scale constellation deployment. It is designed for no fewer than 20 reuses and a low Earth orbit (LEO) payload capacity of no less than 18 tons under recovery mode within the launch zone. On the same day, the Shanghai Stock Exchange (SSE) website showed that LandSpace’s IPO on the STAR Market has resumed review after its financial reports were updated. The IPO was accepted on December 31, 2025, but was suspended on March 31, 2026, due to expired financial statements. As a critical pre-launch procedure, the successful static fire test signals that the Zhuque-3 Y2 rocket is now entering its countdown to launch.

Freemelt Receives Additional eMELT System Order from Jiuli New Material
Freemelt, a Swedish 3D printing equipment manufacturer, has received an additional order from its strategic partner, Jiuli New Material, for an industrial-grade eMELT electron beam powder bed fusion system. The system is scheduled for delivery in Q3 2026, with the order value in line with previously communicated pricing. The two companies signed a strategic cooperation agreement in 2025, enabling Freemelt to leverage local support, technical expertise, and business networks. The new order will focus on application development in China's energy and medical technology sectors. Freemelt's CEO commented, 'This order confirms the value of our technology and allows us to further position ourselves in one of the most expansive and competitive metal additive markets globally.' The eMELT system, based on electron beam powder bed fusion technology, melts metal powder layer by layer in a vacuum environment, making it particularly suitable for processing materials such as titanium, copper, and tungsten.

LPBF High-Strength, Crack-Free CoCrNi Matrix Composite Developed via Grain Boundary Segregation Design at University of South China
A research team from the University of South China, in collaboration with the Leibniz Institute for Solid State and Materials Research in Germany and the Harbin Institute of Technology, has developed a high-performance CoCrNi-based composite tailored for additive manufacturing using a grain boundary segregation design. By introducing micron-sized TiC particles via laser powder bed fusion (LPBF), the team produced crack-free, high-strength CoCrNi medium-entropy alloys. Mechanistic studies show that TiC addition promotes carbon segregation to grain boundaries, significantly lowering grain boundary energy and effectively suppressing hot cracking. During LPBF, partial dissolution of TiC forms nano-scale Cr23C6 precipitates and TiC/TiO₂ core-shell structures, refining the grain size. The CoCrNi-3 wt% TiC composite exhibits excellent mechanical properties and high-temperature oxidation resistance, with the fine-grained microstructure facilitating the formation of a dense Cr₂O₃ protective layer. This work provides a new theoretical framework for designing high-performance alloys for additive manufacturing.
