Just wondering what you use to store your resin? I’ve been looking for a small dark bottle with not much joy. Leaving grey resin in the tray too long the pigment sits at the bottom and also I’m sure it is not good to expose the resin to air for long periods of time.
Ideally I’m thinking small bottels like the form 1 resin bottles that are specifically for storing the resin in the tray. Any suggestions?
As @Zachary_Brackin mentioned, it’s safe to keep resin in the tray for extended periods of time so long as it’s not frequently exposed to intense direct sunlight.
For some resins, pigment will settle to the bottom of the tank overtime, but this can be corrected by gently stirring the tank with the metal scraper. The same thing occurs when resin is left in a container and we recommend that some materials like Castable Resin are shaken prior to printing.
Extended periods of time are - according to your support - no greater than 2-3 months.
Otherwise there’s the risk of the resin getting under the PDMS and attacking the glue holding the window on…
With castable, once it has settled in the vat it does prove problematic to remix - there’s always the risk of damaging the PDMS (I see the newer scrapers have rounded corners - presumably to reduce the risk).
Having spoken with FL staff at IJL, I understand the issue of the vat window being held against gravity may be something that is being addressed (or has been with the new LT vat?).
I was worried the resin would go off in a way being exposed to air or something though thats good to know it does the opposite. The scraper that came with my F2 has pretty sharp edges I wouldn’t touch my pdms layer with so opted getting a plastic sticker scraper.
