The Performance Filter lets you safely and comfortably operate your Glowforge indoors, without venting to the outdoors. It dramatically reduces odors, smoke, and fumes to safe levels; there should be little-to-no odor coming from the exhaust vents of the Performance Filter.
That said, even when used properly, you may still smell odors. Here's what causes them, and how to minimize them.
- Opening the lid after a print. After printing, trace amounts of smoke and fumes remain trapped in the crumb tray, and will escape when the lid is opened and material is removed. This can be reduced by leaving the material in the Glowforge for a minute or two before lifting the lid.
- The materials themselves. After printing, some materials may have an odor for as long as a day or two. This can be minimized by using Proofgrade material, removing and disposing of the protective coating (which has the bulk of the odor), and by setting the materials aside for a day.
- The Glowforge itself. After being used for many hours, tiny particles of dust and resin will accumulate on the Glowforge itself. To minimize the odor, keep the lid closed when not in use, clean according to the user manual, and leave the Glowforge connected to the Performance Filter when not in use.
