Abstract
A retractable purging mechanism is preferably comprised of a bracket that is connectable to a 3D printer. An actuatable shaft is secured to the bracket and the shaft engages a rocker arm, which in turn engages a collecting tray and moves the collecting tray from a first position to a second position. The collecting tray is adapted to receive a material that is discarded when, for example, a different print colour is used in 3D printing. A sweeper is also provided, the sweeper connected to the collecting tray to remove the material from the collecting tray.
