Deep Blue Aerospace installs 12 large-format metal 3D printers for rocket engine production

Deep Blue Aerospace (Shenlan Hangtian), a Chinese commercial launch startup, has deployed 12 large-format metal additive manufacturing systems at its Tai'an facility for producing liquid reusable rocket engine components. The new plant is expected to begin operations by the end of 2026, targeting an annual capacity of 100 rocket engines. This makes Deep Blue Aerospace the largest metal AM service provider in the region by installed machine count.

The move reflects a broader pattern in China's commercial space sector: metal AM is transitioning from prototyping and validation into serial production for mission-critical engine parts. Unlike Western aerospace primes, which often qualify AM parts over multi-year programs, Chinese launch startups are integrating large-format LPBF and DED machines directly into production lines, compressing the qualification timeline through vertical integration and domestic supply chains.

This deployment also signals a shift in the value chain. Deep Blue Aerospace is not just buying machines; it is building in-house AM capacity to control both cost and lead time for complex nickel superalloy and titanium alloy components. For the metal AM equipment market, this represents a growing pull from the Chinese commercial launch segment, which is scaling faster than its Western counterparts and placing larger, more repetitive orders for production-grade systems.
