QiDi Multifilament System for Max 4

QIDI Box Multi-Filament System for the Max 4 Series

The QIDI Box for the Max 4 Series is a multi-filament system with four independent channels, designed for multicolour printing and use with different materials. It supports 1.75 mm filament, automatic spool switching, drying at temperatures up to 65°C during printing, temperature and humidity monitoring, and NFC recognition of compatible QIDI filaments. One QIDI Box holds four spools. The system can be expanded to four units, supporting up to 16 colours or materials for complex projects with fewer manual filament changes.

Four Independent Channels and Dual Gearboxes

The filament feed system uses dual hardened-steel gearboxes and four separate Type 42 stepper motors, one for each channel. It is designed for common filaments as well as more demanding composite materials reinforced with carbon or glass fibre. Supported materials include PLA, PETG, ABS, ASA, PET, PA, PC, PVA and BVOH (after drying), PP, POM, HIPS, TPU 64D, and selected CF- and GF-reinforced materials.

Drying up to 65°C and Humidity Control

The QIDI Box can dry filament while printing, at a maximum temperature of 65°C. Its airtight storage compartment, together with the option to use desiccant, helps reduce the effects of moisture on filament, particularly for hygroscopic materials. Temperature and humidity are monitored in real time, with readings available on the device screen and in QIDI Studio software.

Automatic Spool Change and Issue Detection

When the filament on the active spool runs out, automatic refill switches the feed to a spare spool. This helps reduce interruptions during long prints and makes better use of leftover filament. The system also detects filament shortages, tangles and jams to help address feed issues.

NFC and Printing with Support Materials

NFC enables automatic recognition of compatible QIDI filaments and applies their settings without manual parameter entry. The multi-material design also allows a separate support filament to be used, including materials that can be snapped off or dissolved to simplify printing models with complex geometries. PVA and BVOH must be properly dried before use.

Compatibility and Safety

Not all 1.75 mm filaments are compatible with the QIDI Box. Unsupported materials include TPE, standard TPU, TPU 95A, QIDI PAHT-CF, damp PVA and BVOH, selected Silk filaments including PLA Silk, glow-in-the-dark PLA, and materials that are excessively stiff or flexible. A smart PTC fuse and two temperature sensors monitor operating conditions and automatically cut power if an abnormal temperature is detected.
