The most common 3D printing filaments are hygroscopic materials, which means that they will absorb moisture from the air over time. After a point filament absorbs so much water that it noticeably negatively affects the quality of your prints!

The 3D Printing community commonly uses desiccants to help extend storage life, but they don't actually "pull" the water out of the filament. They just keep it from getting worse. Once wet, filament needs to be heated in a dry environment to dry it out.

This project is a simple tool for removing water from 3D printing filament, and for regenerating used desiccant packets!

Step 1: Tools & Materials


Dremel tool with cut off wheel

Razor Blade/scissors

Diagonal Cutters

Elmer's glue


(1) Rubbermaid 12-Quart Plastic Container

(1) Electric Food Dehydrator


(1) Temp/Humidity Monitor

<p>I bought the items listed and I have noticed my dryer grates are slightly different. In step 5 when the bucket is attached does it have vent holes outside of the bucket.</p>
<p>No it does not and should not. I would recommend NOTt cutting the bucket then to keep the extra large lip to help span that gap. </p>
I already cut it. It wouldn't have been wide enough anyways. I think i need to plug those holes with tape. Correct me if im wrong but it seems the hot air rises from the outer rings. Then circulates down the center. When the rings are seated on top of each other there is a gap for the heat to flow through to the grates and then down.
