Qidi Tech Plus4: High-Speed, High-Precision FDM 3D Printer

The Qidi Tech Plus4 is a state-of-the-art Fused Deposition Modelling (FDM) 3D printer, expertly designed to meet the needs of both enthusiasts and professionals. This advanced machine seamlessly blends high-speed performance with outstanding precision, making it an essential tool for a wide range of 3D printing applications.

Generous Build Volume

The Plus4 features an impressive build volume of 305 x 305 x 280 mm, offering ample space to create large and intricate designs. This substantial build area allows users to print sizeable models in a single session, minimising the need for assembly and ensuring structural integrity.

High-Speed Printing Capabilities

Built with a robust CoreXY structure, the Plus4 achieves remarkable printing speeds of up to 600 mm/s. Complemented by an acceleration of 20,000 mm/s², this high-speed functionality significantly reduces print times without compromising quality. Whether you're prototyping or producing end-use components, the Plus4 guarantees efficiency and precision in every project.

Advanced Extruder Design

At the core of the Plus4 is a direct-drive extruder with hardened steel gears and a bimetal nozzle capable of reaching temperatures up to 370 °C. This design enables smooth and consistent filament extrusion, supporting a wide variety of materials, including high-performance and fibre-reinforced filaments. The integrated throat nozzle structure enhances heat transfer and minimises the risk of clogging, ensuring uninterrupted printing sessions.

Active Chamber Heating

To address the challenges of printing high-temperature materials, the Plus4 is equipped with an active chamber heating system. Its powerful 400-watt heater raises the chamber temperature to 65 °C within approximately eight minutes, effectively reducing warping and delamination. Dual-layer insulation ensures stable and consistent temperatures, resulting in superior surface quality and dimensional accuracy of printed parts.

User-Friendly Features

Designed with user convenience in mind, the Plus4 includes a 5-inch high-definition touchscreen for an intuitive interface, simplifying navigation through various settings and controls. The hands-free automatic bed levelling system employs a capacitive sensor to maintain optimal build plate flatness, improving first-layer adhesion and overall print quality. Additionally, filament runout and tangle detection sensors provide real-time monitoring to prevent print failures.

Material Versatility

Thanks to its high-temperature capabilities and robust extruder design, the Plus4 is compatible with a broad spectrum of filaments. From standard materials like PLA and PETG to engineering-grade thermoplastics such as ABS, ASA, PC, and PA, as well as fibre-reinforced composites, the Plus4 offers exceptional versatility. This flexibility enables users to select the most suitable material for their specific application, whether for functional prototyping or producing durable end-use parts.

Enhanced Software Integration

Running on the open-source Klipper firmware (V0.12.0), the Plus4 provides precise control over every aspect of the printing process. It is compatible with Qidi Tech's proprietary QIDI Studio slicing software, which offers advanced slicing capabilities and a user-friendly experience. For those who prefer alternative software, the Plus4 also supports popular slicers such as Orca, PrusaSlicer, and others, allowing flexibility to suit different user preferences.

Robust Construction and Stability

Built with a sturdy frame and high-quality components, the Plus4 ensures durability and stability during high-speed printing operations. The 6 mm aluminium print bed guarantees excellent flatness, contributing to consistent first layers and overall print quality. Dual independent spindle motors, along with 10 mm linear shafts and spindles, ensure precise movement and positioning, resulting in accurate and reliable prints every time.

Comprehensive Filament Detection System

To further enhance the user experience, the Plus4 is equipped with a comprehensive filament detection system. This includes sensors for filament runout and tangle detection, ensuring that any issues are promptly identified and addressed. This proactive approach minimises the risk of print failures and material waste, allowing for more efficient and reliable printing sessions.

Remote Monitoring and Control

Recognising the need for flexibility and convenience, Qidi Tech has integrated remote monitoring and control capabilities into the Plus4. Through the QIDI Mobile App, users can oversee their printing projects in real-time, make necessary adjustments, and receive notifications, all from their mobile devices. This feature is particularly useful for managing multiple projects or monitoring long prints without the need for constant supervision.

Conclusion

The Qidi Tech Plus4 stands out as a versatile and high-performance 3D printer, adept at meeting the diverse needs of both hobbyists and professionals. With its generous build volume, high-speed capabilities, advanced extruder design, and user-friendly features, it is a formidable tool in the world of 3D printing. Whether tackling complex prototyping projects or producing high-quality end-use parts, the Plus4 is engineered to deliver outstanding results with efficiency and precision.
