Dental LT Comfort Resin is a long-term biocompatible SLA material designed for in-house 3D printing of flexible occlusal splints, night guards, and bleaching trays. It offers enhanced comfort and durability that supports patient adoption and compliance with treatment plans.

Dental LT Comfort Resin is specifically formulated to be flexible rather than rigid, which improves patient comfort and encourages compliance. It is also designed to be easily polished to high optical transparency, reducing polishing time compared to less clear alternatives.

Yes. Dental LT Comfort Resin is certified biocompatible for skin contact and mucosal membrane contact, making it suitable for long-term intraoral appliances. It is manufactured in a Formlabs FDA-registered facility in Ohio within an ISO 13485 and EU MDR certified Quality Management System, inside a certified ISO Class 8 clean room. All applicable FDA registrations and CE markings are in place. You can view the ISO certification on the Formlabs website.

Dental LT Comfort Resin is compatible with the Form 4B, Form 4BL, Form 3B, and Form 3BL printers. It supports a minimum layer thickness of 100 microns and works with the corresponding resin tanks and build platforms for each printer series.

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 Manufacturing Guide.

Formlabs provides a dedicated application guide covering the full production workflow and best practices. You can access it at the Application Guide for 3D Printing Occlusal Splints and Night Guards on the Formlabs Dental website.

Dental LT Comfort Resin has an elongation at break of 33%, a flexural strength of 21 MPa, a flexural modulus of 643 MPa, a Shore hardness of 75 D, and a notched Izod impact resistance of 98 J/m. Full specifications are available in the Technical Data Sheet. Note that properties may vary based on part geometry, print orientation, print settings, temperature, and disinfection or sterilization methods used.
