The problem is that those two goals use two diﬀerent techniques in terms of airﬂow. For the

best air quality, as much air as possible needs to come into the enclosure and then be vented

or ﬁltered out. All of our enclosures come with fans, and we've chosen the CFM ratings to

match the cubic size of the enclosures. This ensures that there's enough airﬂow to keep the

temperatures in the safe zone for ﬁlament types like PLA, which don't like the heat.

At the same time, you want higher internal temperatures for ﬁlaments like ABS, which happens

naturally because the recommended bed temperatures are much higher than for PLA, typically

in the 105-120C range. 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 an acceptable risk,

might want to run higher temperatures for minor warping of ABS parts or print 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 clogging,

and even with no venting of the power supplies, we've never had a power supply fail either.

Your mileage may vary as it depends on many variables, such as ﬁlament quality and the

quality of the power supply in your printer.

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

hour before printing.

The other part of the equation is the printer design. Those printers where the hot end is at the

top of the enclosure make it easier to achieve higher temperatures because the hot air rises to

the top, and the vertical hot end position is ﬁxed. Those printers with the hot ends at the

bottom will always have more problems managing temperature simply because the

temperature is more likely to vary as the hot end goes from the bottom to the top of the

enclosure.

If you're looking to achieve a particular temperature with your enclosure, let us know, and we'll

give some advice on how to manage, but it's not that hard:

Lower Temperature = More Air Flow

Higher Temperature = Less Air Flow
