One advantage of microwave sintering over older methods (like muffle furnaces) is more even heating because energy is deposited throughout the volume of the part, not just at the surface. Reduced thermal gradients -> more predictable post-sinter part dimensions and more uniform mechanical properties. Those are yield enhancers that could give significantly better production economics.
