With the continuous emergence of various advanced aircraft, aerospace companies are facing unprecedented pressure. Product development, inspection, and MRO (maintenance, repair, inspection and modification) level innovations require more efficient manufacturing methods. On the other hand, the need to reduce the weight of parts and optimize the structure of parts, thereby reducing fuel costs, makes additive manufacturing technology useful. The 3D printing solution provided by Brozan has brought many benefits to aerospace companies and defense departments: faster product verification process; more controllable quality; reduced fuel costs through lightweight and component integration; innovative 3D printing casting modes , 3D data recovery, injection mold design and metal 3D printing to improve production efficiency.
