Yes. After three days without a print, the UI displays a warning that directs the user to stir the resin tank with the plastic scraper included in the accessories box.

No, you cannot replace the tank film on either the Form Studio 1 Resin Tank and the Form Studio Resin Tank Pro.

Resin tanks are consumables - they have a lifetime that are primarily driven by the number of layers printed, and the accumulation of wear/damage. Form Studio 1 resin tanks are designed to exceed 75,000+ layers with Formlabs material when maintained correctly. Some competitors numbers:

• HeyGears (Reflex)- lifetime > 45,000 layers
• Anycubic (P1) - lifetime 10,000 (FEP film) - 30,000 (ACF film) layers
• Elegoo Saturn 4 Ultra - 60,000 layers
  
  

The Form Studio 1 Resin Tank uses a film engineered for Formlabs Alpha Resins. It is engineered to deliver fast printing and an improved supported surface finish with Alpha Resins. The tradeoff is the tank film is not chemically compatible with all materials.

Tough 1500 Resin V2 is not compatible with this tank: certain components in those resins damage the film. Many third-party resins carry similar incompatible ingredients. That is the reason for the restriction and why they made the Form Studio 1 Resin Tank Pro

Users making their own settings for Alpha Resins in Resin Tank Pro should expect roughly 60% print speed of what the Standard tank delivers, and the Standard tank costs less. There is no upside to running Alpha Resins in the Pro tank.

Early data places the Standard tank in the same range as the Pro tank and the Form 4 resin tank: roughly 75,000 layers. Some units have already exceeded that figure in testing, but validation is still in progress.

Closed. This is the recommended setting for two reasons: it reduces IPA evaporation, and it is the safer configuration. An enclosed unit contains IPA vapor. An open unit lets vapor escape into the room, where it could reach an open flame or another ignition source nearby. The enclosed wash is the lower-risk setup, not a hazard.
