From: Direct 3-D printing of complex optical phantoms using dynamic filament mixing
Dimensions and photos of the fabricated filament-mixing test phantoms. The schematics of the three printed benchmarks are shown in (a)–(c) with each unique material labeled from 1 to 9. The corresponding filament mixing ratios are shown in the legend. The corresponding photo of each benchmark is shown in (d)–(f).
