Design Principles
"Leverage complementary manufacturing processes to overcome individual technology limitations and achieve superior part quality."
This hybrid approach allows designers to leverage the geometric freedom of additive manufacturing while mitigating its inherent limitations in precision and surface quality through subsequent subtractive processes. It enables the creation of intricate geometries that might be challenging or impossible to achieve with traditional methods alone.

Paragraph starter
The research by Monzón et al. (2024) highlights the potential of hybrid manufacturing, combining Atomic Diffusion Additive Manufacturing (ADAM) with CNC machining, to produce functional copper parts. Their findings indicate that while ADAM offers geometric freedom, it introduces dimensional inaccuracies and surface roughness issues, particularly with slender geometries and inclined surfaces. However, by characterizing these deviations and applying compensation factors, followed by CNC finishing, designers can achieve improved dimensional accuracy and surface quality, making this a viable strategy for producing complex metal components.
