Geometry-Aware Scattering Compensation for 3D Printing

A demonstration of 3D printouts obtained with our method. The Earth diameter is 5 cm.
Commercially available full-color 3D printing allows for detailed control of material deposition in
a volume, but an exact reproduction of a target surface appearance is hampered by the strong
subsurface scattering that causes nontrivial volumetric cross-talk at the print surface. Previous
work showed how an iterative optimization scheme based on accumulating absorptive materials at the
surface can be used to find a volumetric distribution of print materials that closely approximates
a given target appearance.
