Low cost fume hood for 3D printing

In this blog we show our low cost solution for containing fumes and VOCs from our Formlabs Form 3 SLA 3D printer. We essentially encapsulate our printers, along with wash stations, inside of an off the shelf grow tent. An axial fan is hooked up to create negative pressure and a DIY fume hood is born!

This is a great, cheap, and easy way to protect yourself from the smells of resin or IPA. This setup also works well for containing and filtering VOCs and particulate matter (PM) from FDM or filament 3D printing setups.

If you are unable to vent outside for some reason, a charcoal filter or air purifier can be hooked up or placed inside the sealed grow tent instead.

Grow Tent Fume Hood

Grow tents are very cheap and come in a variety of different sizes to fit your printing setup.

Hooking these up to an axial fan to draw negative pressure creates a make-shift fume hood that works wonders at containing and filtering fumes and particulates.

Venting the air outside, or placing a charcoal filter or air purifier inside can vastly improve the safety of your workspace.
