    PCL has a very low Tg. You might be able to print in the 65-85oC range.

    ABS has really good cold impact strength. It's also very easy to print, more forgiving than PLA. If I could only choose those between PLA and ABS I would take ABS. However as Smithy stated above ASA is superior to both of those especailly for a part that will be outside or see UV.

    The trick to a breakaway support with PC is getting the goldilocks adhesion to the material and the build surface. In my experience a PPE/PS alloy with a Tg matching the PC and a MFI of 7-9 g/10min will work nicely. PVA not compatible. The only soluble support that I know of that can go that high a temp is locked up in IP and tremendously expensive for the "maker" market.
