Speeding up that Large Objects: Maximum Flow and a 0.8mm Nozzle

I have been printing really large PLA objects the last month, mainly Reactors for the Laboratory. They are basically Pots with lids and a couple of tulle’s. They are varying in height between 20 and 30 centimeter. Printtime per Reactor was about 30 hours. There was a demand to make Reactors with a higher temperature resistance @60 degrees. As PLA allready softens @50 degrees I had to test other print materials, which had a higher Glas Transition Temperature (GT temp= the point meterial softens, become rubbery. The melting point is much higher). I made a comparison of the Glass Transition
