Abstract
A fume extractor system and method for use with a 3D printer includes a system operable in three conditions including: continuously filtering particulates and fumes at high temperatures during a printing process without intentional removal of pressure from the print chamber; continuously filtering particulates at high temperatures during a print process with intentional removal of pressure from the print chamber, to keep noxious gases retained in the print chamber; and purging the print chamber of fumes and mixing in ambient air to cool the fumes to a temperature low enough to allow adsorption of the fumes created by the printer. The system has a first compartment holding a first filter assembly and a second compartment holding a second filter assembly.
