3D Printing in Cool Temperatures is so much better

[Pattycakes]

Has anyone else notices this? It seems as though whenever I print in cool, low humidity conditions, my printers could out so much nicer looking - at least when I use PLA. Has anyone noticed this? What's the main reason for this? Is it because the PLA hardens faster?

Maybe I'm just imagining it LOL

Woe me living here in Thailand with two seasons: hot and humid and soggy hell... :P

The faster you cool the print the better with PLA, specially for delicate details. Do you have a cooling fan aimed at the nozzle?
And yes, PLA has a sharpish hardening curve, that's why, AFAIK, it contracts less than ABS for example.
