Spare Parts for QIDI MAX4 Accessories

Polar Cooler

The QIDI Polar Cooler is an advanced external cooling solution for FDM 3D printers designed to actively cool the extruder’s cold side and filament feed path. It prevents heat creep-related issues and improves reliability when printing with temperature-sensitive and engineering materials.

 Bimetal Nozzles

The nozzle and throat have an all-metal integrated design for quick removal and very easy replacement.

Bimetal Hotend for QIDI Max4

It is recommended to use only one type of filament in a single nozzle. Switching between multiple filaments in one nozzle may cause nozzle blockage.

 Dual-sided PEI Plate

【Excellent Adaptability】The surface of PEI material is wear-resistant and can adapt to a variety of printing environments and filaments.It is double-sided and reusable.If one side is accidentally damaged,the other side can continue to be used.

【Effortless Model Removal】After the printing process is completed,wait for the flexible PEI spring steel sheet to cool completely,then bend the steel sheet to easily remove the model and the build plate will return to flatness.

【Compatible 3D Printers】The size of the print bed is 390x390mm,which compatible for QIDI Max4 3D printers.

Model Cooling Fan

The Part Cooling Fan, located at the toolhead's base, works in tandem with the Air Duct to swiftly cool extruded filament.

Hotend Cooling Fan

The Hotend Cooling Fan cools the hotend to avoid premature filament softening and clogs.

Hotend Silicone Sock

The Silicone Sock for Hotend is made from high-quality silicone for higher temperature resistance (rated to 300°C printing temperatures).

Ensuring optimal thermal insulation and tear resistance, the silicone sock also provides the nozzle with long-lasting protection from cooling air and plastic adhesion.

Cutter Blade

Cutter Blade is used to cut the filament when replacing the filament or switching between multiple colors.

Waste Bin Pusher Plate Silicone

Connects to the wiping pusher plate, used to drive the wiping pusher plate during printhead wiping and control the opening and closing of the wiping pusher plate.

Wiper Silicone Case

It is used to clean the hot nozzle before starting a print job.

Max4 Print-head Cable

This cable is used to connect the printhead and the printer.

for QIDI Max4 Auxiliary Fan

The Max4 Auxiliary Fan is installed on the left side of the chamber, providing better cooling conditions for high-speed printing.

for QIDI Max4 Motherboard Fan

It is used to cool the motherboard.

Max4 Motherboard

The motherboard is responsible for coordinating the work of all hardware components to ensure the precise execution of the printing process.

Max4 AP Board

High-performance control - handles complex motion algorithms (such as high-speed printing, closed-loop control) to improve printing accuracy and speed.

Multi-tasking - manages printing, temperature control, network communication, camera monitoring and other tasks at the same time.

Intelligent expansion - supports advanced functions such as Wi-Fi/cloud control, multi-sensors, AI detection, etc.

Max4 Adapter Plate

Optimize electrical connections, improve stability and scalability.

Max4 Chamber heater with fan

The Max4 Heater with fan is responsible for heating the printer's print chamber to keep it at a constant temperature. This helps create a stable printing environment and prevents problems such as material warping or poor adhesion, especially when using temperature-sensitive consumables. It ensures that the print chamber is at an optimal temperature, resulting in high-quality printing.

Max4 Extruder

The Max4 extruder and the filament runout sensor are designed as an integrated module, highly integrated and working together. If the filament runout sensor malfunctions and needs replacement, it is recommended to purchase the entire Max4 extruder assembly for replacement. Disassembling or replacing the sensor component separately is not recommended to avoid installation errors, poor circuit connections, and other subsequent problems caused by module separation, thus ensuring the overall stability and safety of the equipment.

Max4 3-in-1 Air Filter

Three-in-one air filter: It consists of G3 pre-filter + H12 HEPA + coconut shell activated carbon, which is used to filter the air inside the cavity and effectively remove VOCs.
