The QIDI Tech X-Smart 3: High-Speed 3D Printing in a Compact Footprint
For makers navigating limited workshop space without compromising on performance, the QIDI Tech X-Smart 3 presents a compelling solution. This compact 3D printer delivers impressive print speeds and quality in a fully enclosed form factor, making it an attractive option for functional prototyping, small-batch manufacturing, and even intricate cosplay components. We put the X-Smart 3 through its paces to assess its capabilities for both novice users entering the high-speed printing world and experienced builders seeking to optimize a dense print farm or a small personal workspace.
Design and Build: Maximizing Space and Stability
The QIDI Tech X-Smart 3 immediately stands out with its thoughtfully designed, fully enclosed chassis. Its modest footprint (approximately 380 x 380 x 400 mm) belies a generous build volume of 175 x 175 x 175 mm, striking an excellent balance for individual users or small-scale print farm operators. The printer utilizes a CoreXY motion system (a precise Cartesian system where the print head moves in X and Y, and the bed moves in Z, known for speed and accuracy), housed within a rigid frame that minimizes vibrations even at high accelerations. The enclosed nature of the printer is a significant advantage, particularly for printing engineering-grade filaments.
Beginner Note: An enclosure helps maintain a stable internal temperature around your print. This is crucial for materials like ABS, ASA, and Nylon, which are prone to warping and layer splitting if cooled too quickly. The consistent thermal environment reduces internal stresses in the plastic as it cools, leading to stronger, more reliable parts.
The X-Smart 3’s construction feels robust, with a focus on quick assembly and minimal maintenance. The direct drive extruder system is integrated efficiently, contributing to the printer’s ability to handle a wide range of materials, including flexibles, with precision. Its size makes it ideal for desktop use or integrating into shelving units, making it a pragmatic choice for makers with constrained environments who still demand high-performance output.
High-Speed Performance Powered by Klipper
At the heart of the QIDI Tech X-Smart 3’s performance is Klipper (advanced open-source firmware that replaces traditional Marlin, leveraging an external computational board like a Raspberry Pi for complex calculations). Klipper enables advanced features such as Input Shaping (a technique that cancels out vibrations in the printer’s frame to reduce ghosting and ringing at high speeds) and Pressure Advance (a feature that predicts and compensates for pressure changes in the nozzle to improve corner sharpness and reduce oozing). These technologies allow the X-Smart 3 to achieve remarkable print speeds without sacrificing print quality.
During our testing, we observed consistent print speeds up to 250-300 mm/s for PLA with accelerations in the range of 10,000-12,000 mm/s². For more challenging materials like PETG+, speeds were conservatively set to 150-200 mm/s with accelerations around 8,000 mm/s² to ensure optimal layer adhesion and surface finish. This performance bracket makes the X-Smart 3 significantly faster than many traditional FDM printers, effectively reducing print times for functional prototypes by 50% or more depending on the geometry.
Maker Tip: For advanced users, diving into the Klipper configuration files (often `printer.cfg`) allows for fine-tuning of Input Shaping and Pressure Advance values. Using Klipper’s built-in resonance compensation tools, often involving an ADXL345 accelerometer, can yield even better results by precisely measuring and canceling out printer vibrations for your specific setup. Self-hosting a Klipper instance provides maximum flexibility and access to the full suite of Klipper’s powerful features.
Material Versatility and Print Quality Assessment
The QIDI Tech X-Smart 3’s fully enclosed print chamber and direct drive extruder make it exceptionally versatile with materials. Beyond standard PLA (Polylactic Acid, a common, easy-to-print, biodegradable plastic), the printer reliably handles PETG (Polyethylene Terephthalate Glycol, known for strength and durability), ABS (Acrylonitrile Butadiene Styrene, strong but prone to warping without an enclosure), and even more demanding filaments like ASA (Acrylonitrile Styrene Acrylate, UV-resistant ABS) and Nylon (a strong, flexible engineering plastic). The hotend is designed to reach temperatures up to 300°C, accommodating a broad spectrum of technical filaments.
For our testing, we focused on Elegoo’s Rapid PETG+ (Extruder Temp: 245°C, Bed Temp: 80°C) and Inland’s PLA+ (Extruder Temp: 215°C, Bed Temp: 60°C). We used a standard 0.4mm hardened steel nozzle, which is recommended for its durability when occasionally printing abrasive filaments. For functional parts, layer heights of 0.2mm to 0.28mm provided an excellent balance of speed and strength, with a consistent surface finish.
Print quality for both aesthetic and functional prints was impressive. Details on small parts, such as gears for a robotics project (available on Printables.com, search for “functional gear sets”), were crisp with minimal artifacts. Overhangs and bridging capabilities were excellent, a testament to the efficient cooling system and precise motion control.

* Print Speed (Perimeters): 120 mm/s
* Print Speed (Infill): 180 mm/s
* Extrusion Multiplier: 0.98 (fine-tuning for specific filament flow)
* Retraction: 0.8mm at 40 mm/s (direct drive friendly)
* Cooling Fan: 30% for first layer, 50-70% for subsequent layers
User Experience and Ecosystem Integration
The QIDI Tech X-Smart 3 aims for an accessible user experience. The printer features a responsive touchscreen interface that allows for basic operations, file selection, and monitoring. Connectivity options include Wi-Fi, Ethernet, and USB, providing flexibility for file transfer and remote control. QIDI provides its own slicer, QIDI Slicer (a customized version based on the robust PrusaSlicer/SuperSlicer codebase), which includes pre-configured profiles for the X-Smart 3. This reduces the learning curve for beginners while still offering the depth of settings that advanced users expect.
For those comfortable with self-hosting, the Klipper firmware at its core means the X-Smart 3 can be fully integrated with popular solutions like OctoPrint (a web interface for controlling and monitoring 3D printers, often running on a Raspberry Pi) or directly via a KlipperScreen (a touch-friendly interface for Klipper, usually displayed on a dedicated screen or tablet) setup. This allows for advanced monitoring, remote print management, and access to a wealth of community-developed plugins and features.
