DIY Enclosures (draft)

Building Your Own Enclosure

Essential elements of an enclosure are filter assembly box and light. It is best to place the control box on the outside of the enclosure due to its propensity for overheating. An automatic fire stop device is useful if one tends to leave their printer unattended for long periods of time.

Filter Assembly Box

As 3D printers emit both VOCs and EFPs (see previous post), two types of filters are needed; HEPA and Carbon. The two filters and a fan comprise a filter assembly box. The assembly can be made to exhaust or recirculate air.

Per Louisana’s Energy Curriculum Guide – “The recommended minimum filter surface area is 2.50 cubic feet per minute (cfm) per square inch of filter area” for heating ventilation air conditioning (HVAC) systems. My 24″ x 24″ enclosure is 8 cubic feet. Using a calculator for fan air exchange, 9 cfm are required for a fan. I estimated I needed a 4″ x 4 “‘ filter.
