Dewu Technology closes Pre-A of tens of millions of yuan for ultra-high-precision metal SLM

Suzhou-based Dewu Technology has closed a Pre-A round of tens of millions of yuan, jointly invested by Jinsha River United Capital and Jintou Zhiyuan. Founded in May 2024, the firm builds ultra-high-precision metal SLM equipment and printing services for complex micro-metal parts, and will use proceeds for equipment R&D, service-line expansion, and sales. Its systems claim ±10 micron forming tolerance, Ra 1 micron minimum surface roughness, and 30 micron wall thickness. Founder Wang Zhou said the as-printed finish cuts post-processing from about 70% of total cost to 10%–20%, delivering full-chain costs 30%–40% below conventional metal AM even when print price is slightly higher.

Demand mix has shifted: aerospace was the entry point and medical devices followed, but since the second half of 2025 consumer-electronics orders for watches, rings, and smart glasses have intensified. Wang places those programs in late design verification, with volume production targeted in one to two years-far shorter than aerospace qualification grind. Named partners include listed firms in China's Apple supply chain, commercial aerospace institutes, Suzhou National Laboratory, medical-device makers, and overseas consumer-electronics brands. Dewu plans 20–30 owned machines in 2026–2027 and 60–80 longer term, with Japan, South Korea, and Europe on the map; not yet in the AM Pulse company index, this Pre-A is a first public capacity signal.

The commercial bet is service economics: micron-level LPBF that shrinks finishing labor, with fleet repeatability across that multi-machine base still to be proven.
