9. Temperature Gauge

The optional thermometer will let you know approximately what temperature it is inside

the enclosure. It attaches to the left side of the door piece using the same hole as the

top-most corner connector as shown. It comes with a longer screw to ﬁt through

everything.

10. Managing Enclosure Temperatures

There's not much to a 3D printer enclosure. Although ours look fancy, functionally

they're not much diﬀerent than putting a card box over the printers since both designs

are passively heated by the heated beds.

We generally get two types of customers:

1. Those interested mostly in air quality.

2. Those interested mostly in print quality.

The problem is 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 for ﬁlament

types like PLA, which don't like the heat there's enough airﬂow to keep the

temperatures in the safe zone.

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

which happens naturally because the recommended bed temperatures are much
