Design Principles

"For hybrid manufacturing processes, implement closed-loop control systems informed by in-situ monitoring to mitigate thermal distortions and maintain dimensional accuracy throughout the build."

Hybrid manufacturing, which combines additive and subtractive techniques, offers significant advantages in design freedom and material efficiency. However, the interplay between these processes introduces unique challenges, such as heat accumulation affecting dimensional accuracy and material properties. Effective in-situ monitoring is crucial for managing these complexities and achieving high-quality outcomes.
