in what units is the temperature?
It seems way to high for ABS.

Maybe its the extensive drying you describe. Try to reduce it and check the result. ("Too much dry(ing) will kill you :)"

Hello,
you can use collapsible core if you can tolerate small parting lines inside of your shape.
Be careful about patents, this things are usually under some patent pending.
