High Print Accuracy

DB 4000 delivered 97% global accuracy within ±130µm and 95% intaglio accuracy within ±100µm, surpassing the category leader.*

Engineered for dimensional accuracy, DB 4000 and its printing workflow accurately reproduce the original STL specifications in the final printed denture, supporting consistent, well-fitting denture bases. 

The color scale helps visualize dimensional deviations between the STL and the scanned denture. Warmer colors are positive and cooler colors are negative deviations in microns.

The green results show passing of internal accuracy specifications
and the orange results are failing.
