With over 13 years of experience in using FDM and FFF 3D style printers one learns quickly the various quirks in the operation of these printers. While they have improved dramatically since the 2011-2012 introduction of desk top printers, there are still some challenges when printing with various filament types. To be specific, ABS ( Acrylonitrile Butadiene Styrene ) has been one of the more popular materials with which to print. However, this material off-gasses when printing at 245 Degrees C and above and the odor can be quite significant. In addition, the gases produced along with some of the fine particles released during printing can become a health concern if not properly vented or isolated when printing occurs.
One of the other issues when printing with ABS is the layer separation that can take place if the object being printed cools to rapidly during the printing process. To minimize this issue you need to enclose the printer and keep the cold air drafts from falling on the printer bed. This enclosure can also also double as a mechanism to reduce the entry of the odors and particulate into the room. The use of a fan powered exhaust system attached to a vent in the enclosure along with a carbon media and HEPA filter will allow for continued use of the printer inside any room or enclosed area without compromising the environmental integrity of the room.
Pure Air Systems has been making fan powered HEPA and Carbon medial filters since 1985. These systems are designed to move from 50 CFM up to 2000 CFM with the ability to control the air volume in 1% increments. These metal framed units come in seven different configurations with the addition of a portable unit that is a prefect fit for the enclosures that would be placed over the 3D printers.
