I am new to 3D printing here. I have Dental SG resin and the Dental model 1L I have printed a few test prints with the Dental SG. No I want to print a dental model with the model resin. How do I efficiently switch between resins? I have all this resin sitting on the bottom of the form 2 resin tank. I don’t want to waste it. Is there a guide for switching back and forth between resins? Thanks. ---

That gets tricky and isn’t recommended. Especially putting resin back into a cartridge as it can contaminate what’s already in it. They recommend a tank for each to avoid this as cleaning tanks kind of sucks. ---

I figured. Pretty cheap. $59. ---

99 for the long life, which I’d suggest. ---

Having different tanks for each material is easiest but you can certainly empty the tank and re-use it with another material. If you’re looking to use a tank with a different material, [filtering the resin](https://support.formlabs.com/hc/en-us/articles/115000015730-Resin-Filtration) into a funnel and back into the cartridge is best practice.
