The above is a blog post I've done on my experiences with temperature and the major problem of heating up a 3D printer, or specifically the resin, when working in an environment where the temperatures regularly or constantly drop below 20C and where you cannot simply heat the entire room to the required temperature. I've mostly focused on the heater aspect of this and haven't gone into detail of enclosures or such, simply as there's a fair bit of freedom of choice in that regard and its for a blog post on "my setup" that I want to do later at some point that shows everything.

The times I've had problems I used a hairdryer to heat up the vat and the resin. After the first few layers the LEDs are neough to keep the temperature over here, IME.

Aye it really depends how much of a temperature drop you experience. If you're just shy of 20C you can often get away with pre-heating and going that way. However I find that if you start hitting 15C and lower it starts to impact the resin as well, especially for prolonged periods.

I've also found that running things "hot" in the print environment (25-30C) helps a lot. I've had the same models peel off presupports with ease when the print environment is at 30C; yet require the "hot water method" or clippers to get off the very same supports when it dropped to 20C and lower.
