SUNNYVALE, CA, USA, Aug 18, 2026 — Carbon, a leader in 3D printing technology, 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.
Key Features of DB 4000 Include:
- ISO 20795-1 Hi-Impact Compliant– Validated to the international standard for high-impact denture base resins.
- High Work of Fracture – 4,000 J/m², tested at 37°C in water under modified ISO 20795-1 conditions, 31% tougher than the category leader’s published results*.
- Better Economics for Labs – Engineered to help labs improve margins on denture bases at a competitive cost per part, supporting greater profitability without compromising strength, accuracy, or workflow efficiency.*
- High Print Accuracy – 97% global accuracy within ±130µm and 95% intaglio accuracy within ±100µm, surpassing the category leader*.
- Broader Patient Coverage – Four gingiva shades — Light Pink, Original Pink, Dark Reddish Pink, and Dark Meharry — Coverage across light, standard, and deeply pigmented tissue tones.
- Built for Carbon Automation & DLS Platform – Designed to work seamlessly with Carbon’s Automatic Print Preparation (APP), part of the AO Suite ecosystem of software, hardware, and materials engineered to work together. As of 2026 launch, DB 4000 is exclusive to Carbon M-Series Printers.
- Familiar Single-Cure Workflow – A simple, one-part, single-cure system that follows the digital denture workflow labs already know, without additional materials or processing steps.
“DB 4000 is the product of an obsessive focus on the mechanics that actually determine whether or not a denture base holds up in the real world,” said Jason Rolland, Ph.D., Chief Technology Officer, Carbon. “We didn’t just want to make an incremental improvement over the category leader* — we wanted the data to make the case on its own. That’s why the number is in the name.”
“DB 4000 is a clear example of how Carbon’s platform, hardware, software, and materials engineered together, let us bring dental labs a material with strong performance across the metrics that matter most, at a more competitive cost per part*,” said Phil DeSimone, Co-Founder and Chief Executive Officer, Carbon. “This launch reflects our continued investment in the digital denture market and our commitment to giving labs better tools, and better margins, to run their businesses.”
Availability
DB 4000 is available now in the United States for dental labs and validated for Carbon’s M-Series printers. To learn more about DB 4000, visit carbon3d.com/material-db4000-labs
