R QIDI TECHNOLOGY PLUS4 High-Speed 3D Printer Review: The Engineering-Grade Workhorse We’ve Been Waiting For?

I remember the frustration vividly. Hours into a 14-hour print for a custom drone chassis, a complex part designed in ABS for its strength and temperature resistance. I had walked away confident, only to return to a spaghetti monster of filament and a warped, useless piece of plastic peeling off the build plate. The ambient temperature in the workshop had fluctuated just enough to doom the project. That experience, and countless others like it, crystalized a need: a printer that wasn’t just a hobbyist’s toy, but a reliable tool. I needed speed to iterate faster, a large build volume for ambitious projects, and, most importantly, a controlled environment to tame fickle engineering-grade materials. The endless cycle of tinkering, failed prints, and wasted filament is a barrier that keeps many creators from realizing their most innovative ideas.

Before You Leap into High-Speed, High-Temp Printing: A Buyer’s Guide

A 3D Printer is more than just an item; it’s a key solution for rapid prototyping, custom part manufacturing, and creative expression. In recent years, they have evolved from slow, unreliable kits into sophisticated machines capable of producing parts with incredible speed and material diversity. The primary benefit of a high-performance model like the R QIDI TECHNOLOGY PLUS4 High-Speed 3D Printer is its ability to break through the limitations of basic printers. It solves the problems of warping with temperature-sensitive filaments like ABS and ASA, enables the use of high-strength composites like carbon fiber-reinforced nylon, and dramatically reduces the time from design to physical object, accelerating innovation for engineers, designers, and small businesses.

The ideal customer for this type of product is someone facing the limitations of their current printer or a serious newcomer who wants to start with a machine that won’t hold them back. This includes engineers needing functional prototypes, small businesses creating custom jigs or end-use parts, and advanced hobbyists looking to work with materials beyond standard PLA and PETG. Conversely, this machine might not be suitable for those who only want to print small decorative items, have a very limited budget, or lack the physical space for a large, heavy unit. For those users, a smaller, open-frame printer might be a more practical starting point.

Before investing, consider these crucial points in detail:

  • Dimensions & Space: High-performance printers are often large and heavy. The R QIDI TECHNOLOGY PLUS4 High-Speed 3D Printer measures over 22 inches tall and weighs a substantial 27 kilograms (nearly 60 lbs). You’ll need a very sturdy workbench or table with enough clearance around it for access and ventilation, especially when printing materials that emit fumes.
  • Capacity/Performance: Look beyond just speed. While the 600 mm/s maximum speed is impressive, it’s the Core XY motion system and robust frame that allow it to maintain quality at high velocity. The large 12″x12″x11″ build volume is a key feature, enabling the creation of large single parts or batch production of smaller ones.
  • Materials & Durability: The single most important factor for advanced printing is temperature capability. A 370°C all-metal hotend with a hardened steel nozzle tip is essential for abrasive materials like carbon fiber composites. Furthermore, an actively heated chamber, like the 65°C one found here, is non-negotiable for preventing warping in large ABS, ASA, or PC prints.
  • Ease of Use & Maintenance: Modern features like fully automatic bed leveling, Wi-Fi connectivity, and a built-in camera drastically lower the barrier to entry and reduce hands-on tinkering time. However, be prepared for routine maintenance like nozzle cleaning, belt tensioning, and lubrication to keep the machine running at peak performance over the long term.

Putting the R QIDI TECHNOLOGY PLUS4 Through Its Paces: A Deep Dive into Performance

A spec sheet can only tell you so much. To truly understand a printer, you have to live with it, push its limits, and see how it performs when a project is on the line. We spent weeks with the R QIDI TECHNOLOGY PLUS4 High-Speed 3D Printer, throwing everything from standard PLA to exotic Carbon Fiber-infused PPS at it. Our goal was to move beyond benchmarks and evaluate it as a real-world manufacturing tool.

The Powerhouse Core: Speed, Stability, and the Core XY Advantage

The headline feature is, without a doubt, the 600mm/s print speed. In a world where 60mm/s was once the standard, this is a revolutionary leap. We immediately put it to the test with a series of benchmark models. A standard “Benchy” boat that takes over an hour on an older printer was completed in under 15 minutes, and the quality was astonishingly good. The secret isn’t just raw speed; it’s control. The Core XY motion system, where the print head moves in the X and Y axes via a clever belt system while the bed only moves down in the Z-axis, is inherently more stable and less prone to vibration-induced artifacts (like “ringing” or “ghosting”) at high speeds. QIDI has reinforced this with an independent dual motor-driven Z-axis, a thick 6mm aluminum hotbed platform, and upgraded 10mm diameter linear shafts. This robust construction is what translates speed into quality. One user accurately noted they tested the same part against their older QIDI i-Fast and found the PLUS4 was “6x faster.” This isn’t just a convenience; it’s a paradigm shift for rapid prototyping, allowing for multiple design iterations in a single day. This is a machine that truly respects your time, and you can check the latest price and availability for this powerful tool.

Conquering Curls and Warps: The Actively Heated Chamber

For us, the most crucial feature is the Second Generation Active Chamber Heating System. This is the component that elevates the R QIDI TECHNOLOGY PLUS4 High-Speed 3D Printer from a fast PLA printer to a true engineering-grade machine. Filaments like ABS, ASA, and Nylon have a high rate of thermal contraction; as they cool, they shrink, which causes the corners of a print to lift off the bed (warping) or layers to split apart (delamination). By actively heating the entire chamber to a stable 65°C with a powerful 400W heater and air circulation, the PLUS4 creates a controlled environment that minimizes these thermal stresses. We printed a large, 10-inch wide electronics enclosure in ASA, a project that would be a guaranteed failure on an open-frame printer. It emerged from the printer perfectly flat with flawless layer adhesion. This capability is what opens the door to creating durable, functional parts that can withstand heat and mechanical stress. As one owner stated, having the enclosure gives you “more success at printing filaments that have a tendency to warp like ABS.” This feature, combined with the high-temperature extruder, is the machine’s greatest strength.

The ‘Just Works’ Experience: Auto-Leveling, Software, and Usability

Speed and material compatibility are useless if the printer is a nightmare to operate. Thankfully, QIDI has focused heavily on the user experience. The fully automatic bed leveling system is a prime example. It uses the nozzle to probe multiple points on the bed, creating a detailed mesh to compensate for any minor imperfections. In our testing, this was a true “set it and forget it” feature. We never once had to manually adjust the bed or worry about first-layer adhesion, which, as many users know, is the most common point of failure. One user confirmed this, saying the printer works “without hassle. Due to its reliable bed leveling system to get that critical 1st layer down and stick properly.” The provided QIDI Studio slicer, a customized version of the popular PrusaSlicer, comes with well-tuned profiles for a huge range of filaments. While it’s simple enough for beginners, it contains all the advanced settings an expert would need. Connecting to the printer via Wi-Fi was straightforward, and sending prints directly from the slicer or monitoring them remotely via the built-in HD camera and web interface quickly became our standard workflow. These quality-of-life features are what make the machine a joy to use day-to-day.

Build Quality and Customer Support: The Unsung Heroes

The last pillar of a great printer is its construction and the company that stands behind it. The R QIDI TECHNOLOGY PLUS4 High-Speed 3D Printer is, as one user aptly put it, “built like a tank.” The all-metal frame provides immense rigidity, which is critical for print quality at high speeds. Thoughtful design touches like the top-mounted handles make moving the heavy machine much more manageable. But what truly sets QIDI apart, according to a chorus of user reviews, is their customer support. We saw countless stories of users receiving prompt, helpful, and effective support. One user recounted, “Every issue I’ve had with it has been my fault and still the support has been fantastic! Evelyn has walked me through troubleshooting… and sent parts out quickly to resolve them.” Another praised a support agent named Andy for sending out an upgraded SSR relay proactively. This level of after-sales support is rare and builds incredible confidence in the investment, turning a simple purchase into a long-term partnership. It’s a testament to the company’s commitment to its customers, a feature that really sets it apart from the competition.

The Community Verdict: What Real Users Are Saying

Scouring user feedback, a clear and overwhelmingly positive picture emerges. The most frequently praised aspect is QIDI’s stellar customer support, with multiple users naming specific support agents who provided “fantastic” and “prompt” help, often sending out replacement parts under warranty without hesitation. This seems to have built a fiercely loyal user base. The second major theme is performance right out of the box. A newcomer to 3D printing noted, “Right out of the box, it performed flawlessly, making my transition into the hobby incredibly smooth.” Experienced users are equally impressed, with one stating they have run “everything from PLA to PPS-CF without any issues.”

However, the feedback isn’t without its critiques. A recurring minor issue mentioned is the difficulty of printing very soft TPU filaments through the standard Bowden tube setup. One user discovered the key was to “Bypass guide tube and direct feed TPU filament” to get it to work properly. Another common note is the noise level; while quieter than expected by some, the fast travel moves can be loud, making it better suited for a workshop or garage than a living room. An early hardware issue with an under-specced Solid State Relay (SSR) for the chamber heater was also noted, but multiple users confirmed QIDI acknowledged the issue and proactively sent out upgraded replacements, suggesting the problem has been resolved in newer units.

How Does the R QIDI TECHNOLOGY PLUS4 Stack Up? A Competitive Analysis

The high-speed, enclosed 3D printer market is more competitive than ever. While the R QIDI TECHNOLOGY PLUS4 High-Speed 3D Printer is a formidable machine, it’s worth examining how it compares to other popular alternatives to ensure it’s the right fit for your specific needs.
