The consistency question

eSUN's biggest volume is in budget-friendly segments where tolerance specs vary per product. VOXFIL's position is different: one standard (±0.02 mm inline-measured, ΔE < 1.5) across everything we make, verified by batch reports you can actually read. For buyers burned by inconsistent batches, that's the difference that matters.
