IBT Flex Resin is designed for two primary dental applications: 3D printing indirect bonding trays for seamless bracket placement and direct composite restoration guides. Both applications benefit from the material's flexibility, tear resistance, and translucency, which support accurate, predictable clinical outcomes. You can read Formlabs' full digital workflow guides for indirect bonding trays and direct composite restoration guides.

The material's optimized flexibility and elongation allow for seamless intraoral placement and removal of trays, supporting fast and accurate bracket placement. Its high print accuracy and viscoelastic properties ensure that the digital set-up transfers reliably to the clinical scenario, reducing the need for additional intraoral adjustments.

When using the material for guided restorative techniques, you should apply a separating agent to the tray to prevent composite material from adhering to it. Refer to the IBT Flex Resin Manufacturing Guide for complete step-by-step instructions.

Yes. IBT Flex Resin is a Class I biocompatible material rated for skin contact and mucosal membrane contact. It is FDA-registered and CE marked under the EU MDR. It is manufactured in Formlabs' FDA-registered facility in Ohio inside a certified ISO Class 8 clean room, within a Quality Management System that is ISO 13485 and EU MDR certified.

Yes. To ensure biocompatibility compliance, you must use a dedicated resin tank, build platform, wash unit, and post-processing equipment that have not been used with other resins. Consult the Instructions for Use for the full list of requirements.

IBT Flex Resin offers a tensile strength of 7.2 MPa, a tensile modulus of 8 MPa, an elongation at break of 135%, a Shore hardness of 77 to 80 A, and 85% transparency on a 2 mm sample. These properties combine flexibility, tear resistance, and high translucency suited to clinical tray and guide applications. Download the full technical data sheet.

The 85% transparency of IBT Flex Resin (measured on a 2 mm sample) allows clinicians to easily visualize critical elements during procedures, including brackets, restorative composite materials, and the dentition beneath the tray or guide.

IBT Flex Resin is compatible with the Form 4B, Form 4BL, Form 3B, and Form 3BL. Compatible tanks include the Form 4 Resin Tank, Form 4L Resin Tank, Form 3 Resin Tank V2.1, and Form 3L Resin Tank V3. Note that product availability may be limited by region; see the regional availability page for details.

Post-processing involves two steps: washing and curing. First, wash parts in isopropyl alcohol to remove excess surface resin. Then post-cure the parts, which is required for biocompatible materials to meet the safety standards set by regulatory agencies. The exact settings for both steps are detailed in the IBT Flex Resin Manufacturing Guide.
