I wonder if this can be addressed by keeping a slight positive pressure of nitrogen or CO2 in the enclosure of the 3D printer?

- nine_k 8y agoFilling your room with CO2 by accident won't be great either. That is, proper ventilation would be needed anyway.
- AWildC182 8y agoCould do a really low volume flow of nitrogen or argon at the extruder like in welding. You'd still want some ventilation but you'd just need a tank, regulator, and tubing instead of a sealed enclosure and you'd probably use less gas. Just enough to prevent anything at the tip from burning.
- nine_k 8y agoYes, ventilation here is more like a fan in a room window than a sealed box and tubes.
