I normally print in PLA due to ease of printing and lack of fumes, would it be ok to print the prusa i2 plastic parts (including extruder parts) in PLA or would the heat melt the PLA while printing with it?
From what I have seen the PLA softens pretty easy so I wouldn't use it for anything near heat. You could try PETG. That melts at about the same temp as ABS.
