9. Attach Air Vents and Filter
The CR-10 Max has an 80mm filter hole and will match the standard charcoal air filter
from 3D UP Fitters or any 80mm vent to hose adapter.
The instructions to attach the air filter are on the air filter product page. If you wish to
print your own hose adapter you will find that on our Thingiverse page. You have two
options: 80mm to 3 inches and 80mm to 4 inches. The larger hoses are easier to find
but can be cumbersome. The 3 inch size is plenty big for adequate airflow.
10. Managing Enclosure Temperatures
WARNING: Printing PLA without the fan turned on may cause clogging
There's not much to a 3D printer enclosure. Although ours look fancy, functionally
they're not much di
ff
erent than putting a cardboard box over the printers since both
designs are passively heated by the beds. How complicated can they be? This
section will explain a little about how they work, and how to manage the temperatures
to get quality prints while protecting your lungs.
We generally get two types of customers:
1.
Those interested mostly in air quality.
2.
Those interested mostly in print quality.
Think Airflow, Not Fishtank
The problem is those two goals use two di
ff
erent techniques in terms of airflow. For
the best air quality, we use the same design as industrial equipment, which uses
airflow to manage air quality. Because of physics, the amount of air moving into the
enclosure has to be equal to the air moving out of the enclosure. When the air moves
out of the enclosure carrying volatile organic compounds it can then be vented to the
outside or run through an air filter.
People often ask us if the enclosures are airtight and have a bottom. If your main
concern is air quality then being airtight doesn't buy you anything since the particles
will just float out when you open the door. It's only by maintaining a negative air
pressure that the particles are reliably kept away from human operators, which means
having openings for air to both enter and exit the enclosure.
