    Form 4 Resin Tank

    Low Force Display™ (LFD) 3D printing uses a flexible yet strong dual-layer film tank for consistent, high-quality prints. Every resin tank includes a reusable lid, making it easy to stack tanks and store resin outside of the machine. With a separate tank for each individual resin color or type, switching materials is as easy as sliding in a new tank.

    Resin Tanks are built to last and deliver consistent performance for at least 75,000 layers of printing — approximately 340 prints using clear aligner models (22 mm tall), any resin, and 100µm layer height

    Form 4 Mixer

    The Form 4 Resin Mixer improves material performance by keeping resin homogenous in the tank during the printing process. A Resin Mixer is required anytime you are printing. Resin Mixers typically last for the lifetime of your printer.

    For convenience, we recommend having one Resin Mixer for each Form 4 Resin Tank.

    Form 3 Resin Tank V2.1

    Low Force Stereolithography (LFS)™ 3D printing uses linear illumination and a flexible film tank to turn liquid resin into flawless parts. A key component of the LFS process, the strong dual-layer film at the bottom of the Form 3 Resin Tank, allows for a dynamic and precise print process.

    Notice: Form 3 Resin Tank V2.1 is compatible with all Formlabs resins, but is required for use with some specific materials. There are two previous versions of the Form 3 Resin Tank, Tank V1 and Tank V2, each with their own compatibility requirements. Read more about all tank versions, compatibility, lifetime, and maintenance in our support article.

Manufacturing Guide

Instructions for Use: Dental LT Comfort Resin

Washing

LT Comfort Resin may be washed using either a Formlabs-validated wash unit (1) or an ultrasonic wash unit (2).

The foundational step in any SLA post-processing workflow is to remove excess resin on the surface of the parts through an alcohol wash. Please refer to the material's manufacturing guide/IFU for washing instructions.

Curing

For biocompatible materials, post-curing is necessary to achieve the safety standards determined by regulatory agencies. Please follow the material’s manufacturing guide/IFU for proper post-processing.

FAQ

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.
