Calibrating E steps for new filament

Is it a good idea or do I need to calibrate my E steps after I switch to a new filament due to the different types I use (to make my prints accurate)? E.g. calibrate when switching from PLA to ABS/PETG?

Using heat-set inserts with SLA printed part

I have an SLA printed part I want to put a brass threaded insert in using a soldering iron. The insert is slightly larger than the hole so I would assume the edge will melt and re-freeze around the teeth. Are there any issues with melting SLA or…

My print is warping: how can I ensure that it cools evenly?

My print is warping and I suspect it is because of uneven cooling. How can ensure my print cools evenly? Should I put a fan on the bed? Will no fan and a tall skirt help? Or are my edges curling up for another reason?
