In the aerospace sector, core components often carry extremely high value and demanding manufacturing requirements. Hot-section parts such as turbine blades and integrally bladed rotors (IBRs/blisks) can cost hundreds of thousands to millions of RMB each. Their production involves advanced materials, precision manufacturing processes, and long delivery cycles. These components operate in extreme conditions, making wear, cracks, and thermal erosion unavoidable over time.

Without advanced metal 3D printing remanufacturing technology, operators and engine manufacturers face a difficult dilemma: either invest heavily and wait extended periods for new replacement parts, driving up operating costs and grounding critical assets, or scrap these ultra-expensive components due to lack of repair capability, resulting in massive financial and material waste. Beyond economic loss, this directly affects fleet availability and readiness. Therefore, the development and adoption of high-precision metal 3D printing repair technology has become essential to ensuring sustainable, efficient, and high-readiness aerospace operations.
