R QIDI X-PLUS3 High-Speed 3D Printer - Industrial CoreXY Klipper

In this review the R QIDI X-PLUS3 is presented as a fast, heavy-duty FFF/FDM machine aimed at professional makers and small production shops; the single biggest reason to buy is its dramatic speed and throughput enabled by a CoreXY design and Klipper firmware, which together support up to 600mm/s print speed and extreme acceleration for much shorter print times. Out of the box setup is straightforward and the printer is designed to handle high performance materials using an independent heated chamber, making it a practical choice for users who need reliable, warp-free parts from engineering filaments.

Key Features

• CoreXY & Klipper: CoreXY motion with Klipper firmware reduces print times and improves motion control for faster, more precise production prints.
• High-Speed Performance: Capable of 600mm/s top speeds and 20000mm/s2 acceleration to cut long prints significantly while keeping decent surface quality.
• Independent Heated Chamber: Chamber heats to 65C quickly to minimize warping and layer separation when printing ABS, ASA, PA, PC and other engineering materials.
• Dual Hotends & Materials: Two nozzle types (copper alloy and hardened steel) plus a direct drive extruder allow printing a wide range of filaments including fiber-reinforced options.
• Improved Extrusion and Cooling: Lightweight print head, higher gear ratio and increased extrusion flow help maintain consistent extrusion at high speed for accurate layers.
• Open Source Software: Firmware and software are open for tinkerers who want to customize or optimize the printer workflow.

Who It's For

The X-PLUS3 is aimed at professional users, makerspaces and small production environments that need high throughput and the ability to print engineering-grade filaments without significant warping. It is well suited to designers and service bureaus who will benefit from the faster cycles and heated chamber when producing ABS, PETG, PA or reinforced parts.

Hobbyists who want extremely simple, low-cost hobby printing or those who only print PLA may find this unit overkill; likewise, users who prefer a fully enclosed ecosystem with minimal configuration may prefer a simpler desktop model rather than an open-source focused, high-performance machine.

Pros & Cons

Pros

• Very high top speed and acceleration reduce print time for large batches and prototypes.
• Independent heated chamber to 65C and drying box support warp-free prints of ABS and other high-temp materials.
• Dual nozzle options and direct drive extrusion broaden material compatibility including carbon and glass filled filaments.

Cons

• The advanced speed and configuration are best appreciated by experienced users; newcomers may need time to optimize settings for best results.
• High-speed printing still requires tuned profiles and quality filament to avoid artifacts at extreme feed rates.

Our Verdict

The X-PLUS3 is a compelling choice for professionals who need industrial-level speed and consistent performance with engineering filaments; its CoreXY design, Klipper firmware and heated chamber deliver real productivity gains. For teams and serious hobbyists who will tune profiles and take advantage of open source firmware, it represents good value compared with slower, less capable machines.

Frequently Asked Questions

Can it print ABS and other high temperature filaments?
Yes. The independent heated chamber reaches 65C and the machine is designed to print ABS, PETG, PA, PC and fiber-filled filaments with reduced warping.

Is the printer ready to use out of the box?
The X-PLUS3 ships not requiring assembly and includes operating instructions, but experienced users will want to tune Klipper profiles for high-speed printing.

Are the firmware and software locked down?
No. The firmware and software are open source, allowing enthusiasts to customize and optimize printer behavior.
