Can't pay 150 € each time for Formlabs Resin !?! Any other way?

[printgeek3d]

The Form 3 does not have something like an "open mode" like the Form 2 and you cannot refill a used cartridge as the machine will block it being as empty.

So normally it is not possible to print with 3rd party resins. I wonder what the resellers really said about allowing it in a few months as so far Formlabs hasn't said a word to add open mode(it is not in their interest to allow it).

The only option to print with 3rd party resin in the Form 3 is by using the "Universal Cartridge" by ProtoART.
You can fill the cartridge with any 3rd party resin you want.
Several of the 3rd party resin manufacturers like ApplyLabwork are developing their resins using this cartridge. So that resin is a very good option. But there are others like Harzlabs(russia) and Druckwege(germany)
