IBT Flex Resin - FormLabs

The IBT Flex resin by Formlabs is a Class I biocompatible material that stands out for its flexibility, tear resistance, and translucency. The IBT Flex resin complies with the ISO 13485 standard, making it suitable for use in medical sectors, particularly in dentistry, to 3D print indirect bonding trays or direct composite restoration guides ("composites") that are easy to plan, use, and remove.

It is important to note that it is the responsibility of manufacturers and their respective customers and end users to evaluate the biocompatibility and performance of all printed components for the intended applications and uses (see the Related Posts tab).

The IBT Flex resin is designed to provide consistent and predictable clinical results, ensuring a superior patient experience. With an elongation at break of 135% and enhanced flexibility, it facilitates the placement and removal of devices in the oral cavity with ease, speed, and precision.

The resin's improved transparency further enhances this efficiency, allowing for 85% transparency at 2 mm thickness. Additionally, its optimized viscoelasticity allows for a perfect fit of the guides over the teeth, ensuring precise transfer of the digital model to the clinical setting. This reduces the need for additional intraoral adjustments, streamlining the overall process.
