Abstract
An airborne particle detector comprises a light source to emit a light beam through a target space adjacent to a heat source of a 3D printer, a detector to detect an amount of light of the light beam having passed through the target space, and a detection engine in communication with the light source and the detector to detect airborne particles in the target space using an amount of light detected by the detector.
