I got a Form 2 for a few weeks from work since they don’t use it anymore, (the guy who operated it is gone) and the thing is amazing.I have got a few questions about the consumables though (resin cartridge + resin tank), an i’m hoping a few Form 2 owners can answer these.the resin tank only lasts for two cartridges according to Formlabs, is that true? if you always print different stuff in different places on the clear tank, the tank should last longer?how is your experience with cleaning the tank for using it with another resin?i have clear resin V2, but the newer one is V3, which should yellow less over time. can i mix the old clear V2 in the tank with a newer clear V3 resin cartridge? (there seem to be about 270ml in the tank)i’m getting a cartridge almost empty error, but only printed about 500ml so far. if there is 270ml in the tank according to formlabs, and an empty cartridge weights about 330 grams (mine currently weighs 560 grams), then there should be 230ml left in my cartridge.is there a working alternative resin that doesn’t come from Formlabs? 160€ is quite a bit, if it’s around 80 € / liter i would use this printer for more than really important stuffcan i refill an empty resin cartridge from Formlabs with this third party resin?is there a sub for the Form 1/2 printers specifically here? http://ift.tt/2rbGuTs
