MPBF Metal 3D Printing in Aerospace: Challenges and Solutions

A promising application of MPBF metal 3D printing is to produce high-performance aerospace parts like turbine blades, heat exchangers and structural components which require high strength, low weight and complex shapes which are difficult to be produced with traditional manufacturing procedure. MPBF metal 3D printing provides a solution which can produce parts with complex internal structure, optimized design and shortened delivery time.

However, there are still some challenges when applying MPBF metal 3D printing in aerospace industry. The main challenge is the consistency and reliability of the procedure. MPBF metal 3D printing produces high-quality parts through accuracy control of laser parameters,  powder properties and process parameters. Any variation or fluctuation in these parameters can result in defects or inconsistencies in the part, affecting its performance and reliability.

Another challenge is the post-processing of MPBF metal 3D printing. Parts need to be cleaned, heat treated and machined to meet the required surface finish, dimensional accuracy and mechanical properties. However, post-processing is time-consuming, expensive and is difficult to be automated, which will limit the scalability and cost-effectiveness of MPBF metal 3D printing.
