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.

A fume extractor system for use with a 3D printer;
- the system comprising:
- (a) a first compartment holding a first filter assembly;
- (b) a first pump moving gas through the first filter assembly;
- (c) a first conduit conveying gas from a chamber holding a 3D printer to the first filter compartment;
- (d) a second conduit conveying gas into the chamber holding the 3D printer;
- (e) a second compartment holding a second filter assembly;
- and
- (f) a second pump moving gas through the second filter assembly;
- wherein at least one of the first filter assembly and second filter assembly includes an adsorption filter for removing noxious fumes.
