Product description
Evenly heated filament dryer box
The design of the built-in fan and insulation cotton in the filament dryer box makes the filament heated more evenly and dried faster. Due to the built-in fan, the printing filament dryer may be a little louder in working than those without fan.
Why we need the FIROS Filament Dryer Box?
3D printing filament absorbs moisture from the air, and damp wire can cause many printing issues. The filament dryer will help you remove excess moisture
Button Introduction
Press (M) key to enter adjust drying time mode or select temperature level mode, △ and ▽ button can set the drying time or select temperature level.
3 filament outlet holes
The filament dryer is designed with 3 filament outlet holes to meet your needs for a variety of printing position
Compatible filament spool
The size of our filament dryer box is: 10.24*3.98*9.84in(L*W*H). It can store filament spools less than 3.35in in width and diameter within 8.07in.
Operating Instructions
Moisture and improper storage of 3D printing filament will not only affect the printing results by creating bubbles, stringing, clogging, poor adhesion, layer shift, but also affect your printing experience. Filament dryers are designed to keep filament dry and dehumidified. You can heating during the printing, filament dryer box provides a dry storage environment for 3D printer filament.
The adjustable time range of 3d printer filament dryer is from 1 hour to 36 hours, and there are 3 heating levels, 45℃±3°/113℉±37.4℉, 55℃±3°/131℉±37.4℉, 70℃±3°/158℉±37.4℉; you can choose the right heating level and time according to the type of 3d printing filament.
Support all 8.07in(Diameter)*3.35in(Width)(Φ205mm*85mm) 3D printing filament; Perfectly compatible with 99% of 1.75mm/ 2.85mm diameter 3D printer filament, such as PLA, PLA+, ABS, ABS+, PETG, PVA, TPU, PC, PA, etc. The filament dryer is designed with 3 filament outlet holes and insulation cotton to meet your needs for various print positions and protect you from burns while printing.
The 3D printer filament dryer adds a built-in fan for all-around surrounding heating and rapid drying. Due to the fan design, the 3d printer filament dryer will be slightly louder than one without a fan. Filament of any material absorbs moisture from the air, and damp filament will cause many printing issues. You can use the dryer box as filament dehydrator or filament storage box.
Press (M) button to enter the drying time or temperature level setting mode, △ and ▽ button can set the drying time and select different temperature level. The design of two rollers inside the box allows you to print while drying. Tips: Do not put the filament in 02 or 03 heating level for too long. Prolonged high temperature environment will melt the filament, make them sticky and unusable.
