The money will fund iterative R&D of its ultra-high-precision SLM equipment, expansion of printing service production lines, and market growth.
What does it do? Founded in Suzhou in May 2024, Dewu develops selective laser melting (SLM) equipment for micron-level metal additive manufacturing. It is one of the few Chinese companies to master the core technology, serving consumer electronics, medical devices, and aerospace clients.
The pitch: Its equipment controls forming tolerance within ±10 microns and can form structures with walls as thin as 30 microns. That precision cuts costs: founder Wang Zhou says post-processing typically eats about 70% of a part's total cost, but Dewu compresses that to 10%-20%, making the overall solution 30%-40% cheaper.
Why it matters: Traditional metal 3D printing has long struggled with precision, surface roughness, and post-processing costs, leaving printed parts as "blanks" needing heavy CNC grinding and polishing. Dewu's approach delivers surfaces close to finished-product standard.
Why now? In 2026, Dewu is raising early and fast — a quick re-raise that signals investor appetite for its technology and its orders from leading consumer electronics clients.
The signal: China is racing to close gaps in high-end precision manufacturing, and metal additive technology sits at the centre of that push. Backing a young startup with academic depth and patents — more than 30 filed at home and abroad — reflects rising bets on domestic capability in a field still dominated by cost and quality trade-offs.
