Volatile Organic Compounds (VOCs) and Ultrafine Particulate Matter There have been no proven emissions from 3D printers Greenhouse gas & smog Carbon dioxide and fine inhalable particulate matter
2. When 3D printers produce an object, what action/step occurs after the computer design (CAD), slicing, load filament onto printer, and sending the object to the printer: Thermoplastic sheets are contoured by a laser Radiation is utilized to soft thermoplastic to produce a shape Filament moves through a heated nozzle Items are selected through a drop-down menu on the printer
3. Research suggests that caution should be used when operating in poorly ventilated spaces. The most effective way to set up a 3D printing space should include which of the following? The use of enclosure An enclosure with a ventilation fan Use of a HEPA filter All of the above are recommended as the most effective combination
