#/min. The SERs for total volatile organic compounds (TVOC) varied from 0.2 μg/min (GLASS) to 40.5 μg/min (ULTRAT, an ABS-based filament). Particles started to evaporate extensively from 150 °C. At 300 °C, only 25% of the particle number remained with the size distribution mode peaked at 11 nm. The particles collected on the quartz filter were mainly composed of semi-volatile organic compounds (SVOCs) associated with the plasticizers, flame-retardants, antioxidants of the thermoplastics, and cyclosiloxanes which may be used as lubricants in the 3D printer.
