PolyBox™ Edition II

PolyBox™ Edition II is a filament storage box that allows you to store materials in their optimum printing environment while still being able to print with them. PolyBox™ Edition II can house up to two 1kg spools simultaneously or one 3kg spool and is compatible with both 1.75mm and 2.85mm filament diameters.


Protect your filament - The PolyBox™ Edition II provides the optimum printing environment for 3D Printing filaments. Humidity is maintained below 15% to increase filament life span and to ensure consistent mechanical properties from the start to the end of the spool.

Easy Maintenance / Monitoring - The PolyBox™ Edition II includes a built in high precision thermo-hygrometer to allow the user to monitor the humidity and temperature inside the PolyBox™. Maintaining the PolyBox™ Edition II is simple with the included microwavable desiccant.

Safe / Low Cost - The PolyBox™ Edition II is an incredibly safe and economical out of the box solution powered by a small LR44 battery. That means no power cables or expensive electricity costs.

Multiple Materials - The PolyBox™ Edition II can print with up to two 1kg spools simultaneously, perfectly suited for spooling multiple printers, dual extrusion printing or load one 2kg / 3kg spool for longer prints.

Compatibility - The PolyBox™ Edition II features six rubber exit holes, three installed in the base and three installed on the reversible transparent cover. With the PolyBox™ Edition II changing spools is as easy as ever. No matter how your printer feeds, the PolyBox™ Edition II is designed to suit your workspace.

Moisture content in filaments can cause a multitude of problems from inconsistent extrusion to poor surface quality and ultimately delivering a printed part with weak mechanical properties due to poor layer adhesion.

In environments with >20% humidity, water molecules are quickly absorbed into the filament forming polar bonds with the polymer chain. When the filament passes through the hot end the moisture rapidly expands, boiling and rupturing the filament. This causes bubbles in between layers, inconsistent extrusion due to material expansion and poor surface quality due to the fluctuating flow rate.

Materials such as PVA, PVB and Nylon are particularly susceptible to moisture absorption, however other materials like ABS, PETG and PLA are also hygroscopic.
