Protect and Store Your Filaments

PolyBox™ is a filament storage box that allows you to store your materials in their optimum printing environment while still being able to print with them.

PolyBox™ features a thermo-hygrometer to monitor your filaments inside the box. The humidity is regulated by large desiccant bags which absorb moisture from the air inside the PolyBox™, specifically designed for hygroscopic materials such as PolySmooth™, PVA or Nylon.

The PolyBox™ can house two 1kg spools simultaneously or one 3kg spool and is compatible with both 1.75mm and 2.85mm filament diameters.

This version II, has three outlet ports on the base and three on the cover. Works well

for those humidity sensitive filaments. I printed a simple desiccant holder with a small

12 volt fan to speed up the absorption once the chamber lid was attached. I dry the

desiccant and filament in a food dehydrator before use. Those Nylon filaments require

a dry/polybox to get the best results.

A Well Manufactured Product!

Product: Polymaker PolyBox Version 2

A little expensive, but it is very well made and I love the fact that I can have two reels setup inside for printing. Change over is very simply. Some people think that these are a waste of time, but I have had the experience of blow outs in my prints due to moisture in my filament, so for me it is no waste of time!
