Well, Stratasys itself sells ULTEM in filament form with a diameter of 1.75 I believe. It is incredibly expensive. As far as their specs they actually say that special venting isn't needed. Mind explaining glass transition point to a newbie? So if the filament is melted, but it hits room temperature it may immediately freeze again? Which would destroy the extruder? Thanks for your input!by sternlicht - General
Has anyone tried printing with ULTEM? I know stratasys sells ULTEM filament and I would really like to print with it. But I don't know the printing temperature for it is. Ideas?by sternlicht - General
