Carbon Launches DB 4000, a High-Impact Denture Base Resin Delivering High Work of Fracture, Print Accuracy, and Better Economics for Dental Labs

Carbon announced the launch of DB 4000, a high-impact denture base resin engineered for dental labs producing 3D-printed digital dentures on Carbon's M-Series printers. FDA-cleared and compliant with ISO 20795-1, DB 4000 combines high fracture toughness and high print accuracy with a more competitive cost per part than leading alternatives*, delivered through a familiar single-cure workflow that integrates directly into the Carbon ecosystem. DB 4000 takes its name from its mechanical properties: a work of fracture of 4,000 J/m², tested at 37°C in water under modified ISO 20795-1 conditions, 31% tougher than the published Work of Fracture results of the category leader for denture base resins*. As Carbon puts it: 'The number in the name is the proof.' In addition to work of fracture, DB 4000 averaged 97% global accuracy within ±130μm and 95% intaglio accuracy within ±100μm in Carbon's internal validation testing, 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. DB 4000 is available now in the United States for dental labs and validated for Carbon's M-Series printers.
