So we all know the lifetime specs touted by Formlabs listed here say that the tank needs to be replaced after either a set time, or a set volume of resin or number of layers have been printed - whichever comes first.
I had been pouring Tough 2000 , Elastic and Rigid resin out of the tanks after each use in hopes that would extend the lifetimes. I recently noticed a little spot under my Tough 2000 tank which had just marginally passed the “weeks exposed to resin” requirement. Support has told me to switch the tank (they have graciously given me a coupon code for a new tank free of charge).
Now, I have a couple of questions that I hope can be answered…I don’t think there has been much transparency on this topic:
Has Formlabs been doing continued long term testing with tanks, and is there any further information on tank lifetime that can be shed? I presume what’s listed is a conservative number and it would be nice to know a) whether internal testing has shown this can be extended, or b) whether there is work being done to extend the lifetimes. I am admittedly running some tanks past their lifetime with no issues, but just carefully inspecting the film before each print.
Does pouring resin out after use extend the lifetimes at all? Is this something Formlabs has even tested?
Hoping this thread may shed some more information on tank lifetime. I’m OK with the cost of replacing tanks as a consumable - that’s the cost of business, but I admit that I’m still dissapointed that the LT tanks on the Form 2 lasted longer.
