Why Dual-Cure Is
Non-Negotiable

Why Dual-Cure Is Non-Negotiable

Single-cure resins often lack the molecular architecture required to withstand constant cyclic stress. Carbon engineered a proprietary dual-cure chemistry that increases durability after thermal activation. Get the accuracy of a 3D print with the fatigue resistance of a traditional injected resin.

Performance Data

FP3D Outperforms the Competition in Long-Term Fatigue Testing

Dual-cure means predictability. It helps ensure that when a flexible partial is prescribed, the device performs reliably for over three years.

If FP3D lasts similar to duraflex and much longer than other 3D printed flexible partials, this is very important. It sounds like the other brands should market as a "temporary partial denture resin" as I would be embarrassed to provide a restoration that only lasted for that short period of time.

DESIGN PRINT CURE FINISH SHIP

01

Case Intake

Receive scans or traditional impressions and prescription. Digital or physical inputs handled just like any other removable case.

02

Digital Design

Design the flexible partial framework in your CAD software. FP3D is compatible with most common dental CAD tools and file formats.

03

3D Printing

Mix FP3D resin per protocol, load into your Carbon printer, and run the validated print job. Carbon's DLS™ technology helps ensure consistent, high-accuracy output.

04

Cure, Finish & Deliver

Thermal bake per the validated protocol. Bond base and teeth. Perform the final UV cure. Finish and polish. Package and ship.

From design to delivery, the workflow mirrors what technicians already know:
Design → Print → Cure → Finish → Ship.
