Just thought I would post this here…I seem to either know what I’m doing…or just have extremely good luck.
Note that I always inspect my tanks for any wrinkling, tears, pinholes, or delamination spots before a print.
I also pour all the resin out for aggressive resins (Rigid 4K, Tough 2000). I’ve been doing this on the Form 3 and Form 3L for years and it seems to have helped in extending lifetimes. I don’t think this is surprising, especially on the 3L tanks which have a significant amount of weight - even though Formlabs has said otherwise.
This tank is starting to get some wrinkling on the right side of the black gasket so I’ll be changing it after the latest print just to be safe…but I bet you could push it even further.
Similarly, this is my Tough 2000 tank for my Form 3 and 3L.
Knock on wood that my tanks don’t spontaneously leak after posting this…
I had tanks leaking before reaching their 100% lifetime. Luckily this was only on the Form 3, not the 3L. I use Rigid 4000 99% of the times and I “safely” stretch it to 150% and no more than 200%. Most of the time that works, except when it doesn’t
I’ve also had some tanks leak before reaching their 100% lifetime. Formlabs has always been great in replacing those for me.
Let’s hope that I continue to be lucky for a long time to come haha…
Madness! I’m hovering around 400 on some of my tanks
Just curious @horton - do you pour your resin out of the tank or does it sit with a full tank of resin?
It’s had Tough 2000 in it since day 1. I’ve only poured it out once to filter and replace. I don’t store the tray in the printer - I keep it in a drawer in the original box.
A new tray was sent to me by Formlabs after a few prints - the sides were kind of crinkling but looking back, it’s fairly normal. The new tray is still in the box, never been used.
Wow crazy. We must have some incredible luck haha…
Hey @leonhart88 and @horton ,
Those are definitely some impressive tank lifetime stats! While I’m thrilled you guys are both still having good success with the prints on those tanks, please do be aware of the tank lifetime expectations on our site to be safe. It is definitely a good habit to manually inspect the tanks periodically, since any tank past its recommended lifetime is more likely to cloud or leak over time (although not a guarantee, as you two have both seen first-hand!). The biggest concern, in my humble opinion, is the tediousness of leaning up a resin spill, especially with the resin capacity of a 3L tank lol.
Additionally, if you ever do have tanks that are expiring or faulty before their expected lifetime (as @Eks mentioned), we are always happy to replace consumables that have not performed to our expectations. Feel free to contact our Support Team in these cases.
