Hi all,  
I am waiting for the delivery of the Form 3L. While the time goes, I was having a read around this forum and it started building up my concerns about the printer and materials. The biggest I have now, before even starting all the fun is: how long will the material last in the tank if not used all? Do I have to shake it from time to time, to keep it healthy?  
Appreciate some advice.

Hi @Kicked,

Great question! The answer will depend on a variety of factors, including the type of resin and how much the tank has previously been used. For more information, be sure to [check out our support article](https://support.formlabs.com/s/article/Resin-tank-lifetime-Form-3L-Form-3BL?language=en_US)!

With regards to shaking the resin, the wiper in the resin tank will mix the resin before and during printing. However, it’s always a good idea to shake the resin _cartridges_ before starting a print!
