Designed for extended use, Resin Tank LT (Long Term) supports high volume production and streamlined workflows for professional applications that require consistent, high-accuracy prints. Resin Tank LT delivers a longer lifetime compared to the lifetime of the standard Resin Tank.
Resin tank lifetime varies based on resin type, print settings, and maintenance. For best printing results, use a different tank for each type of resin. Learn about resin compatibility for Resin Tank LT.
Resin Tank LT features a chemical resistant plastic tank frame with a clear acrylic window and a film-coated elastic layer. The tank holds the liquid resin during prints while the laser passes through the tank window and cures resin against the film.
Resin Tank LT’s chemical resistant construction improves print performance for demanding professional applications.
Formlabs recommends using Resin Tank LT when printing with certain resins known to wear down tanks more quickly.
Learn about Resin Tank LT features that support high volume production:
Protective Film: A thin protective film coats the elastic layer on top of the clear acrylic tank window. The film preserves print accuracy and detail by protecting the elastic layer from clouding, wear, and contamination. The film increases tank lifetime to a maximum of 30,000 layers of printing depending on a variety of print factors. To maximize Resin Tank LT performance, protect the delicate film from punctures and gouges, which cause irreversible damage to the tank.
Anti-Spill Tank Design: Large tank grips simplify switching and storing tanks. The tank frame and lid design minimize spills and allow the tank to stay covered during insertion and removal.
Automatic Wiper Release: The wiper ejects during tank removal for faster, easier switching in streamlined workflows.
Tank Label: To track multiple resin tanks, write useful information on the white label. Include information such as the material type and the date of first use. Learn how to use Dashboard to manage materials and multiple tanks.
Setting Up Resin Tank LT
Learn how to insert and remove Resin Tank LT. Avoid spilling resin onto the printer, and protect the optical surfaces on the resin tank from contamination.
Wear gloves when handling parts and surfaces with uncured resin. Learn more about resin handling and safety for Formlabs materials.
To maximize the spill-resistant design, keep the plastic lid on Resin Tank LT when transporting, storing, inserting, or removing tanks.
Hold Resin Tank LT using only the tank grips to avoid contaminating the clear acrylic tank window with fingerprints or other contaminants. The tank window, located on the underside of the resin tank, is one of the optical surfaces on the Form 2. Optical surfaces must remain clear for the laser to cure resin successfully. Any contamination, dust, or debris on optical surfaces can interfere with the laser’s pathway and cause print failures.

Inserting Resin Tank LT
Follow these steps to insert Resin Tank LT into the Form 2:
1. Insert the resin tank
1. Lift the Form 2’s amber cover. Use the tank grips to hold Resin Tank LT, with the wiper resting inside the tank. If the tank contains resin, cover the tank with the plastic lid to align the wiper and minimize the risk of spills during insertion.
2. Align and insert the four small feet of the resin tank into the corresponding slots in the tank carrier on the printer.
3. Hold the front tabs and carefully push the tank until the tank feet lock into the slots on the tank carrier. Check the touchscreen display to confirm that the Form 2 detects the tank. The Form 2 will only detect the tank when the tank is fully inserted.
TIP:When inserting or switching tanks, inspect the glass optical window and clear acrylic tank window for any dust or contamination. The glass optical window and tank window are optical surfaces, which must remain clear for optimal print results. Learn how to clean the glass optical window and tank window to ensure consistent print results.
2. Lock the wiper
With the tank installed in the Form 2, lock the wiper and remove the plastic lid.
To lock the wiper in place:
1. Align and insert the wiper foot into the wiper mount.
2. Push the wiper toward the tank.
3. Ensure the wiper foot is securely locked into the wiper mount.
3. Insert the build platform
After installing the tank and wiper, insert the build platform.
If the resin tank has been sitting in storage, use a rounded spatula to stir the resin and gently scrape the film-coated elastic layer before printing.
Resin may settle if stored in resin tanks for longer than a week without printing. Stirring and scraping ensure even material properties across the liquid resin.
CAUTION:Only use a spatula with rounded corners to scrape the film-coated elastic layer. Avoid using sharp tools because they may damage the delicate film.
Removing Resin Tank LT
Follow these steps to remove Resin Tank LT from the Form 2:
1. Remove the build platform
Always remove the build platform before removing the resin tank to avoid dripping resin onto the optical window.
2. Remove the resin tank
With the build platform removed, cover Resin Tank LT with the plastic lid to align the wiper inside the tank and to minimize the risk of spills.
To remove Resin Tank LT:
1. Hold the front tabs of the resin tank.
2. Gently pull the front tabs of the resin tank to release the tank feet from the tank carrier. The Resin Tank LT wiper ejects during removal.
3. Store the covered resin tank
When not in use, properly store Resin Tank LT to extend tank performance and resin lifetime in the tank.
Storing Resin Tank LT
Store resin tanks in a cool, dry place out of direct sunlight. Use the plastic tank lid to protect any resin in the tank and stack multiple tanks for easy storage.
TIP:Keep all resin tanks out of direct sunlight to preserve the resin’s material properties. Learn more about resin lifetime and storage.
Always store tanks containing resin with the lid installed. While the tank frame material blocks wavelengths of light that can cure resin, the top and underside of each tank may remain exposed to light. When storing resin tanks outside the printer, protect exposed parts of the tank from ambient light, which can degrade the material properties of the resin inside the tank.
Store tanks on clean, level surfaces that prevent light from passing or reflecting through the clear tank window on the underside of the tank. Choose a location outside of direct sunlight, such as the original packaging box or a storage cabinet. Prevent dust or abrasive objects from touching the tank window. Consider placing a low-lint material, such as microfiber cloth, underneath the tank to protect the tank window from scratches.
Resin Lifetime Inside Resin Tank LT
Store unexpired resin either in a covered Resin Tank LT inside the printer or properly stored with the lid installed and away from ambient light. Check the Safety Data Sheet (SDS) for additional storage instructions specific to the resin type.
Empty or use any excess resin before storing resin tanks for longer than 2 months. Do not pour liquid resin back into the original container.

Resin Tank LT Lifetime
All resin tanks are consumables. Expect to replace Resin Tank LT after 20,000-30,000 layers or when wear on the film-coated elastic layer begins to affect print quality.
