I'm new to it- I got a used stratasys dimension. dual type- one filament for model one for support. But- the canister that holds the filament has a microchip in it that the printer reads--and sets the heat.I cant put a lower temp water soluble filament in the support canister- it runs at 210.I am trying to figure out if i need to blow 4 grand on the ultimaker--or go cheapand dont say BIBO!! been there-- still hurting from itthanks for your inputhappy plinking!
