Differentiators
- —3D lithography foundry instead of planar 2D lithography
- —Wafer-scale multi-material 3D fabrication
- —Sub-100nm / submicron metal structure resolution
- —Claims of ~10x lower cost at scale and up to 10,000x lower cost in low-volume use cases
- —Cost scaling based on materials rather than layers
