Carbon launches DB 4000 denture base resin

Carbon has announced DB 4000, a denture base resin for dental labs producing 3D-printed digital dentures on Carbon M-Series printers. The resin is FDA-cleared, complies with ISO 20795-1 and is designed to combine fracture toughness, print accuracy and competitive cost per part compared with leading alternatives*, using a single-cure workflow within the Carbon ecosystem.

DB 4000 is named for its reported work of fracture of 4,000 J/m², tested at 37°C in water under modified ISO 20795-1 conditions. Carbon reports this value is 31% higher than the published work of fracture results of the category leader for denture base resins*.

In Carbon’s internal validation testing, DB 4000 averaged 97% global accuracy within ±130µm and 95% intaglio accuracy within ±100µm. The material and workflow are designed to reproduce original STL specifications in the final printed denture to support consistent denture base fit.

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 and reported by Carbon as 31% higher than the category leader’s published results*.
• Lab economics – Designed to help labs manage denture base production costs at a competitive cost per part while maintaining strength, accuracy and workflow efficiency.*
• Print accuracy – 97% global accuracy within ±130µm and 95% intaglio accuracy within ±100µm in Carbon’s internal testing, reported as higher than the category leader*.
• Patient shade coverage – Four gingiva shades: Light Pink, Original Pink, Dark Reddish Pink and Dark Meharry, covering light, standard and deeply pigmented tissue tones.
• Carbon automation and DLS platform compatibility – Designed for use with Carbon’s Automatic Print Preparation (APP), part of the AO Suite ecosystem of software, hardware and materials. At launch in 2026, DB 4000 is exclusive to Carbon M-Series printers.
• Single-cure workflow – One-part, single-cure system that follows existing digital denture workflows without added materials or processing steps.

DB 4000 is available now in the United States for dental labs and is validated for Carbon M-Series printers.
