iDryer X

A universal filament drying solution for 3D printing enthusiasts. You can build it using affordable and accessible parts - for example, an old heater, a spare fan and heatsink, a storage box, and any insulation material. The list of parts is limited only by your imagination.

DIY builds are available in the DIY section.

There is also a KIT version that includes everything you need: pre-machined enclosure parts, electronics, metal base parts, spool holders, a heater, and a fan. Assembly instructions for the KIT version can be found in the iDryer v3 section.

Dryer Advantages

  • Heating up to 110°C

    Set your desired temperature via menu and the device will automatically maintain it throughout the drying process. Capable of drying any filament available on the market.

  • Humidity Control

    Automatic heating when the humidity exceeds the set threshold.

  • Spool Weight Monitoring

    Measures the spool weight and alerts when filament runs out.

  • Energy Efficiency

    iDryer is highly energy-efficient, allowing continuous 24/7 operation without breaking your budget.

  • Low Cost

    iDryer is a cost-effective DIY solution. All components are affordable and printable on a 3D printer.

  • Build It Yourself

    A dryer for 4 spools with built-in weight tracking can be assembled for under $80-100, making iDryer a unique solution in its class.

Firmware

The firmware file contains all possible configurations.

Arduino Bootloader Firmware

Not Recommended

  • No watchdog timer
  • No servo support
  • No additional PWM channel
  • No spool weight monitoring
  • No longer actively developed

Minicore Core Firmware

  • Watchdog timer enabled - auto reset on failure
  • Servo support
  • Additional PWM channel
  • Extended menu and functionality
  • Improved firmware safety

Arduino core firmware can be used on early versions but is not recommended. It's better to buy a programmer, reflash the bootloader, and use the safer firmware.
