Passively heated enclosures depend entirely on the room temperature as a starting

point. If you're trying to print ABS in an unheated garage in the winter, the temperature

inside the enclosure will never get hot enough. The bed heater has only enough energy

to increase temps from the baseline. If that baseline is 72F, you've got a good chance

of getting into the sweet spot. If the baseline is 50F, you'll be lucky to break 72F in the

enclosure itself.

ABS and Nylon

You want higher internal temperatures for ﬁlaments like ABS, which happens naturally

because the recommended bed temperatures are higher. With the fans turned on, we

shoot for internal temperatures between 35C and 40C for 3D printers that use E3D hot

ends because E3D recommends that temp range avoid clogging. Keeping the

temperatures in that range puts the least stress on the equipment and follows the

manufacturer's guidelines.

This works great for people either interested primarily in air quality or those who are

risk-averse and don't want to take a chance of clogging their hot ends or decreasing

the useful life of their printers.

More experienced 3D printer owners, though, for whom a clogged nozzle is a known

risk, might want to run the temperatures higher for less chance of warping ABS parts

or printing nylon. In those cases, you can turn oﬀ the fans or even print one of the vent

covers and not vent at all. We do the latter on our internal print farm on a couple of

machines where the temperature when printing ABS gets as high as 46C. They've

been running like that for years with no ﬁlament clogging. We've never had a power

supply fail with no venting of the power supplies. Your mileage may vary as it depends

on many variables, such as ﬁlament quality and the quality of the power supply in that

particular printer.

If you're looking for the highest temperature possible, try turning the bed heater on for

an hour before printing.

Perfect Enclosure Printing with PLA

Since PLA is happy at room temperature, the only reason to enclose it is for improved

indoor air quality. PLA typically prints with a bed temperature of 60C so that it will heat

the enclosure less than ABS right oﬀ the bat. Make sure to print with an enclosure fan

and monitor the internal temperature, which should ideally be in the 30-35C range or

lower if you can get it.

If you'd like to lower the temperature further, you can always buy a more powerful fan,

but the easiest thing to do is crack the front door a little to increase airﬂow. But won't
