Managing Quality across the Additive Manufacturing Process Chain
Additive manufacturing has seen growth in manufacturing applications ranging from topology optimized parts for weight reduction, to consolidation of complex multipart assembly. However, the transition from prototyping to small-scale production is slow due to reproducibility, which further adds to time and cost of aerospace qualified materials and print recipes.
Connected quality metrics across the entire process chain, provide a comprehensive solution to address quality at each stage of AM, from the qualification of incoming raw materials, in-process feedback during printing to the final qualification of the finished parts. This unlocks correlation between the process controls and their effect on porosity and crack formation, dimensional tolerances, surface roughness and even microstructure control. The versatility of our solution enables a closed loop solution to identify, isolate and mitigation solutions, thus reducing the development and qualification cost of AM parts in aerospace industry. Such a solutions will help in accelerating production of critical aerospace parts using additive manufacturing.
- Highlights:
- Accelerated identification and mitigation of key parameters affecting quality
- Multi-length scale porosity and defect detection
- Use of X-ray CT beyond just the NDT
- Use case of connected quality solutions in the development of Heat Exchanger and Novel Turbine Blade
