DIY 3D Printer Enclosure Guide

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.

My Enclosure

3D Printer Enclosure.

Blog post dated April 19, 2018.

This two door enclosure is two years old. I am pleased with practically all of the design decisions I made. One error I made was in designing the filter assembly. It was not until my recent round of research that I learned the carbon filter should be changed often and easily accessible compartments are needed for both filters.

I did not know until recently that the HEPA filter I used was unacceptable. Not because it was not a good HEPA filter, but because I ripped it while trying to remove it from its case, where it should have remained. I know now that the filter must remain potted in its case to be effective.

One other change needed for the enclosure was insulation around the doors. I will be using rubber window seal to correct this.

Enclosure Update, July 2020

For this update, I sealed opening edges with window seal; changed the door handle; removed the hooks and latches; added magnetic door closure; and created another filter assembly. The filter assembly is explained in another post. I will be making another filter assembly sometime in the future.

The magnetic closure was made using angle irons and repurposed magnets from alarms I purchased from the dollar store. Here is a link to the print file for the magnet holder. I stopped the print to place the magnet before reaching the top cover. The magnet was not a tight fit in the cavity, but it holds well for door closure.
