Summary

Inverse rendering compensated for scattering in dense bioresins and preserved small channel geometry.

A tomographic volumetric bioprinting system used physically based inverse rendering to optimize projected light through cell-laden hydrogels. The authors report printing 500-micrometer vascular channels at 20 million cells per milliliter and, with refractive-index matching, operating at 41 million cells per milliliter. These are preprint demonstrations of print fidelity in bioresin, not evidence of functional tissue or clinical readiness.

Why it matters
