## Summary

A team led by Professor Liu Changmeng at Beijing Institute of Technology has pioneered a single-crystal additive manufacturing method based on unsteady pulsed growth in a micro-melt pool, achieving meter-scale titanium alloy single-crystal additive manufacturing for the first time. The results were published in Nature on October 21 in a paper titled "Additive manufacturing ultralong and architected single crystals," with corresponding authors Liu Changmeng, Cui Yinan of Tsinghua University, and Yinmin Morris Wang of the University of California, Los Angeles.

## Why it matters

The paper presents the mechanism and cross-material validation of seed-crystal-free single-crystal additive manufacturing, which readers can use to assess its impact on the barriers to manufacturing single-crystal components.
