FAQ

Why are there only power levels but not temperature?

The 360° drying system creates a temperature distribution inside the PolyDryer™. For that reason, a single temperature can't represent the true situation as it varies around the spool. Other elements like the room temperature, initial moisture content, spool size, and material type and weight also affect the internal temperature of the box.

How do I know what setting should I use?

The sticker on the dry dock lists all suitable power levels for most common materials. In general, using higher power level and longer drying time can achieve better drying result. If you are using materials from other brands, please check the softening temperature of the filament first before using a higher power level.

What spools can fit inside the PolyDryer™？

The maximum capacity of PolyDryer™ box is 205 Φ * 78(H) mm. This means all 1kg spools or less from Polymaker can fit in the PolyDryer™ and most 1kg spools or less from the other brands can fit in the PolyDryer™. For smaller spools use the internal spool roller for a better experience.

How long can materials stay dry in the PolyDryer™ Box?

The PolyDryer™ Box was designed with excellent sealing and silica gel desiccant to extend your filament storage time. In our internal experiment( an environment of 20℃ and 60% RH), the humidity inside the PolyDryer™ Box changed less than 5% in 30 days. In a comparison test the sealing capability of the PolyDryer™ Box is ~1.5 times that of a DIY storage box.

Can I print and dry at the same time with PolyDryer™？

Yes, the PolyDryer™ has a continuous drying mode. Materials can be either pre-dried on the PolyDryer™ before printing or the PolyDryer™ can be set to continuous drying mode for drying while printing.

Why does the silica gel change color to pink during drying?

As the hot air removes moisture from your material, the silica gel desiccant helps out by soaking up some of that moisture, making the drying process even more efficient. After a while, you might notice some of the pink desiccant turning back to blue, especially when drying on power level 3. This change is a good sign as it means there's less moisture inside the PolyDryer™ Box, and the hot air is doing a great job of drying both your material and the silica gel desiccant at the same time. It's PolyDryer™ Box, letting you know that everything's working just as it should! The silica gel has been certified safe.

What is continuous drying mode for?

For best results seal the PolyDryer™ box with the airlocks as soon as the drying cycle has finished. If you aren't able to do this, continuous mode continues to dry the filament until you're able to reseal after a drying cycle. And continous drying mode will not stop until you turn it off.
