[Malcolm] finally got fed up with the fumes produced by his 3D printer, so he decided to setup this rather extensive fume exhausting system.
He already has a pretty awesome setup with his Type A 3D printer inside of a filing cabinet, with a plastic tote above it to keep his filament from absorbing too much water. But as you know, the fumes released while printing ABS are actually pretty bad for you. With this in mind he 3D printed adapter rings and fitted a fan salvaged from a space heater to the outside of his filing cabinet. A dimmer switch provides variable fan speeds and some dryer vent tubing reroutes the fumes to central vac piping which then goes directly outside. When the system is not in use the piping can be plugged to prevent cold air from entering the house. It’s a fairly clean build but [Malcolm] wants to make a nicer enclosure for the fan and speed control circuit.
The major problem we see with doing something like this is removing too much heat from the build chamber which can always affect print quality. Do you vent your 3D printer?
