11. Managing Enclosure Temperatures
There's not much to a 3D printer enclosure. Although ours look fancy, they're similar to
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 primarily in air quality.
2. Those interested mainly in print quality.
The problem is that those two goals use two di
ff
erent techniques in terms of airflow.
For the best air quality, as much air as possible must 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 enough airflow for
filament types like PLA, which don't like the heat, to keep the temperatures in the safe
zone.
At the same time, you want the internal temperatures higher for filaments like ABS.
This 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
