TiO₂ Dye PPF Scaffold Accuracy – 2-Plate Test Scaffold Diameter Measurements^*

Sample Number	Plate 1 Diameter (mm)	Plate 2 Diameter (mm)
1	5.90	N/A**
2	6.02	5.83
3	5.93	5.92
4	5.97	5.84
Mean	5.92
Std Dev	0.07

^*Four 2-plate test scaffolds were rendered using a 150 s exposure time and a 200 mW/dm² irradiance. The resin used for these samples contained a 2:1 PPF/DEF ratio with 2 wt% BAPO and 1 wt% TiO₂. For each test scaffold, the diameter of each plate was measured using digital calipers. The expected diameter was 6.0 mm. The observed error is approximately 2 times the Perfactory device’s tolerance of 35 microns.

^**This plate rendered well but was damaged during post-processing.
