"tomographic printing exhibits severe light scattering degrading print resolution as structural thickness/ cell concentrations increase, overcome controlling light wave alignment rather than just modifying brightness... projects high-fidelity 3D light directly into rotating tube of photosensitive gel... prints structurally precise/ high cell-survival rate... 70X increased light efficiency over conventional providing highly scalable pathway for rapid, clinically viable tissue engineering/ regenerative implants"
