@Brian_Merrigan: Our resin tank has cracked significantly in the same corner, and a crack runs vertically down that entire corner now to the base of the tank. So far it’s holding and not leaking, but it will completely fail eventually and we will have to get a new tank. Formlabs is aware of the problem and their manufacturing team is working on changes to the tank. See Broken resin vat from late last month – you’re not alone. I’m hoping to hold out the redesigned tank is available.
That corner is particularly fragile, as the plastic is thinner to make a pouring “spout”. For me, the spout has not been particularly effective, it tends to result in resin ending up going everywhere except where I want it to go. I would have preferred a regular-thickness corner back there, just like the other three.
