Product description: QIDI Box system for QIDI Q2 3D printers
The QIDI Box is an advanced filament management system for QIDI 3D printers, expanding printing capabilities to include multiple colors and materials. A single module supports four spools, enabling automatic filament switching, filament flow monitoring, and material drying at temperatures up to 65°C during printing. The enclosed design helps maintain filament in optimal conditions, and with expansion, the system can handle up to 16 colors. This version is designed to work with the QIDI Q2 printer.
The most important functions of the QIDI Box system
- Four filament slots: four spools can be operated in one QIDI Box system
- Expandable system: connect up to four modules, allowing printing in up to 16 different colors
- Drying even while printing: filament drying function at temperatures up to 65°C
- Double gears: a mechanism using hardened steel components to ensure stable filament feeding
- Independent motors: each filament channel has its own stepper motor
- Spool change automation: system that switches to a spare spool when filament runs out
- Filament monitoring: Supports detection of tangling, clogging, or end of filament
- Filament identification: automatic recognition of compatible materials
- Temperature and humidity measurement: conditions inside the device monitored in real time
- Enclosed spool space: Store filament safely inside the QIDI Box between prints
- Desiccant Space: A structure with a space designated for a desiccant
- Independent channel indicators: separate indicator light for each filament channel
- Security: PTC protection system and two temperature sensors
Combining multi-color 3D printing with a filament drying function
One of the main functions of the QIDI Box is the automation of printing using multiple filaments. This solution allows for the use of both different colors and compatible materials designed for multi-material printing. A single module has four channels. The system's capabilities can be expanded by connecting multiple QIDI Box modules. The manufacturer anticipates the interconnection of up to four modules. An extensive configuration can be useful for projects requiring a larger number of colors or materials, without the need for manual reloading of spools. Creating such a system requires additional QIDI Box modules and appropriate expansion accessories. The QIDI Box also functions as an active filament dryer . The manufacturer's maximum drying temperature is 65°C , and the process can occur simultaneously with printing. This allows the filament to be kept in controlled conditions even during long-term printing.

Each of the four channels of the mechanism has its own stepper motor, which ensures independent material transport for each spool.
Reliable mechanism with Auto Filament Refill function
The filament transport mechanism utilizes dual gears made of hardened steel . The manufacturer notes that the solution is designed for stable feeding of a wide range of filaments, including materials containing carbon or glass fiber. Each of the four channels has its own stepper motor, so material transport is carried out independently for each spool. The QIDI Box also features an Auto Filament Refill function, which automatically switches to a spare spool when the current material runs out. This feature can reduce the need for manual intervention during long prints if properly prepared spare filament is present in the system and also improve the utilization of material remaining on multiple spools.
Temperature and humidity control
The QIDI Box allows for enclosed storage of filament without the need to remove the spools after use. The design includes space for a desiccant , which can be placed inside the device. The manufacturer also equipped the system with a manually operated ventilation opening. The QIDI Box allows for temperature and humidity measurements inside the device . The manufacturer claims that it can display current data both on the screen and in the QIDI Studio software. The QIDI Box also utilizes additional safety mechanisms related to the active heating system . The manufacturer declares the use of PTC protection and two temperature sensors for real-time monitoring. If an abnormal temperature is detected, the system automatically disconnects the power supply to the heating system. The solution works with a filament drying function operating at temperatures up to 65°C .

The automatic identification function allows you to match filament information without having to manually enter the appropriate settings each time.
Automatic filament identification
The QIDI Box supports automatic recognition of compatible filaments. The manufacturer describes it as NFC Intelligent Recognition , and the technical specifications table lists support for RFID identification. This feature allows you to automatically match information about the appropriate filament without having to manually enter settings each time. The availability of automatic recognition depends on the filament used.
Filament compatibility
QIDI Box is designed to work with 1.75 mm diameter filament. The manufacturer also specifies the allowable dimensions of spools mounted within the system. Spools with widths from 50 mm to 72 mm and diameters from 195 mm to 202 mm are supported. QIDI also advises that the device is not directly compatible with cardboard spools . When using such spools, the manufacturer recommends using an appropriate adapter or spool ring. Compatible materials include PLA, PETG, ABS, ASA, PET, PA, PC, PP, POM, HIPS, TPU 64D, as well as dried PVA and BVOH . Selected composite materials are also supported, such as ABS-CF/GF, PLA-CF/GF, PETG-CF/GF, PPS-CF, and PET-CF/GF . This extensive list allows the system to be used for both standard printing and for projects requiring technical materials. Not every 1.75mm filament is designed for use in the QIDI Box. The manufacturer lists TPE, generic TPU filaments, TPU 95A, QIDI PAHT-CF, wet PVA and BVOH, and some PLA Silk and PLA Glow-in-the-Dark varieties as unsupported . Other materials that QIDI considers excessively stiff or flexible may also be excluded. Therefore, before using a non-standard filament, it's worth checking its compatibility with the manufacturer's current documentation.

By connecting up to four modules, the system can support up to 16 filaments, making it a great tool for creating projects of various nature.
Practical applications of QIDI Box
The QIDI Box is ideal for projects requiring automatic color or material changes . The system can be used for decorative models, prototypes, multi-material projects, and prints using a separate support filament. Automatic switching to a spare spool is useful for long-term prints, while active drying allows for simultaneous material preparation while printing.
Examples of applications:
- multi-colored models and decorative elements
- prints using several compatible materials
- designs with soluble or breakable support materials
- long-lasting prints using a spare filament spool
- printing from materials requiring controlled drying
- projects using selected technical and composite filaments
