Industrial-Grade Design

The QIDI PLUS4 has a professional look and robust build designed to withstand heavy workloads.

Key design features:

Enclosed chamber with a 65°C heating capability, ensuring better print adhesion and reduced warping.
Rigid aluminum frame for durability and vibration reduction at high speeds.
Touchscreen interface with intuitive controls.
Integrated lighting to monitor prints easily.

Its enclosed, temperature-stable design makes it stand out for users printing advanced engineering materials.

Blazing Print Speeds – 600mm/s

Speed is one of the printer’s standout specifications:

Maximum speed: 600mm/s, significantly faster than most desktop 3D printers (typically 100–200mm/s).
High acceleration enables rapid layer changes without sacrificing accuracy.
CoreXY motion system ensures stable and precise movements.

For professionals, this means faster prototyping and reduced turnaround times, making it suitable for business use.

370°C Direct Drive Extruder

At the heart of the QIDI PLUS4 is a 370°C direct extruder with an integrated nozzle, capable of handling high-performance filaments.

Extruder advantages:

Handles advanced thermoplastics like PPS-CF, nylon, PC, ABS, and carbon-fiber composites.
Direct drive design improves extrusion consistency and reduces clogs.
Integrated nozzle enhances heat transfer for stable high-temp printing.

This setup allows users to print not only consumer materials like PLA and PETG but also industrial-grade materials that demand extreme heat.

Heated Chamber (65°C)

The fully enclosed chamber supports active heating up to 65°C.

Benefits include:

Reduces warping of high-performance plastics.
Improves layer adhesion for strong functional parts.
Enables stable printing of filaments prone to shrinkage.

This feature brings the printer closer to industrial machines, making it capable of producing end-use components.

Fully Automatic Bed Leveling

One of the most user-friendly features is automatic bed leveling. With built-in sensors and advanced calibration:

No manual adjustment is needed.
Ensures a perfect first layer every time.
Reduces setup time and increases reliability.

For both beginners and professionals, this means greater print success rates with minimal intervention.

Large Build Volume

The QIDI PLUS4 offers a generous build size, accommodating medium to large models and batch production. While compact enough for workshops and offices, it has the volume to create functional prototypes, cosplay parts, engineering tools, and end-use products.

Software & Connectivity

QIDI includes its proprietary QIDI Print slicer, optimized for speed and material profiles. However, the printer is also compatible with third-party software such as Cura and PrusaSlicer, giving users flexibility.

Connectivity options include:

Wi-Fi & LAN for remote printing.
USB drive support for offline printing.
Cloud compatibility for monitoring and managing prints remotely.

Noise & Cooling

Despite its high speed, the PLUS4 is engineered to minimize noise and maintain print quality. Its advanced cooling system includes:

Dual-part cooling fans for consistent layer adhesion.
Enclosed chamber sound-dampening for quieter operation.

This makes it usable even in home studios or shared workspaces.

Real-World Applications

The QIDI PLUS4 is suited for a wide range of applications:

Engineering prototypes – mechanical parts, enclosures, tools.
Functional parts – durable, heat-resistant, and load-bearing components.
Education & research – advanced material experiments.
Small-batch production – custom end-use products.
