The use of 3D Printers has grown 1000 % over the past few years. Many schools, businesses, entrepreneurs, hobbyists and individuals now own a 3D Printer. The majority of the printers used in the schools and homes are the smaller FFF or FDM filament style printers that print with various types of plastic or composites. These printers can print over 30 different materials and their tool head nozzles can reach temperatures at or above 300 degrees celsius ( 580 F ). When melting these materials during the printing operation, small amounts of sub-micron particulate are produced which depending upon the materials used for printing may create some health issues when inhaled by the user. Air filtration for 3D printing is now becoming a major concern.
Pure Air Systems, an Indiana based company, has been making HEPA based air filtration systems since 1985. Their fan powered units range in volume from 50 CFM to 2000 CFM and their systems all use commercial grade HEPA’s, variable speed drive motors, industrial fans and all metal housings.In the past year a number of the PAS Portable units ( 250 CFM ) and the 600HS ( 600 CFM ) units have been used to filter the air from one or more filament style printers to remove the less than 20 micron sized particles from the air. HEPA filters used in the PAS units are certified at 99.99% at 0.3 microns. Much of the particulate generated by the printers is in the 1 to 10 micron range which can be inhaled and trapped in the lungs. Over time this could create some significant lung problems and severe side affects. More studies are being done all the time to determine the cause and affect.
In many cases the Pure Air Systems units are attached to special enclosures that are used to cover the printers and confine the particulate to one area. One of the better 3D Printer Enclosures is made by LiteWorld LLC., http://www.liteworldllc.com . The PAS units are very powerful allowing one of them to be used to filter the air for multiple printers.
