After going through many acrylic tanks on my Form 2, I’m wondering why Formlabs has never implemented a metal tank. The castable resins have been very caustic, and they have a tendency to crack the acrylic tanks. I have an LT tank but never tried it…I was told by others they last a little bit longer than the original tanks, but they are still susceptible to breakdown. Even the product listing in the shop shows that the LT tanks should be replaced every 1-2L of resin. That’s about what I get out of my regular tanks.
As I start evaluating my options on the market, I’ve noticed that most of the other manufacturers have metal tanks with film on the bottom that is inexpensive to replace.
