VF Space validates metal 3D-printed rocket engine on Nuri 5th launch, targets commercial space market

VF Space, a South Korean additive manufacturing company, has successfully validated its metal 3D-printed rocket engine through its participation in the fifth launch of the Korea Aerospace Research Institute's (KARI) Nuri rocket on May 8, 2026. The company's GAIA-1 engine, produced using its proprietary Wire Laser Additive Manufacturing (WLAM) process, was integrated into a thrust vector control system for the launch. VF Space CEO highlighted that the flight test confirmed the engine's performance and reliability in actual space conditions, marking a critical step toward commercializing its large-format metal AM technology for the space sector.

This milestone represents a significant technical validation within the aerospace qualification grind, moving from ground testing to a certified launch environment. VF Space's approach combines Powder Bed Fusion and Powder Directed Energy Deposition for smaller components with WLAM for large engine structures up to 1.5×1.5×2.1 meters, addressing the specific challenge of producing large, complex propulsion components with reduced lead times and material waste. The company's focus on wire-based DED positions it against established Western players in the large-format metal AM space while leveraging Korea's growing aerospace ambitions and supply chain localization trends.

The practical next step for VF Space is converting this flight validation into qualified production contracts, particularly with Korea's expanding small satellite launch program. The company must now demonstrate that its WLAM process can deliver consistent mechanical properties and geometric accuracy at production volumes that justify the capital investment. For potential customers in the defense and commercial space sectors, the key question remains whether VF Space's technology offers meaningful cost or lead-time advantages over conventional manufacturing or competing AM approaches for engines of this scale.
