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.

For use with Form 3 and Form 3B.

The Resin Tank blocks light and is made from shatter-resistant polycarbonate. It comes with a reusable lid and wiper, making it easy to stack tanks and store resin outside of the machine.

Resin Tank LT by Formlabs is the new and more resistant tank for your Form2.
It is designed to have better performance with resins that tend to quickly consume the tank like Dental SG resin and High Temp resin.

A spare Build Platform can speed up your workflow, whether you’re changing resins or starting a new print while you remove your part.

For use with Form 3 and Form 2.
