If you've been frustrated by the trade-off between print speed and quality in the 3D printing world, the QIDI Plus 4 might just be the solution you've been waiting for. This professional-grade machine represents a significant leap forward in desktop 3D printing technology, offering blistering 600mm/s speeds without compromising on the precision and reliability that serious users demand. Having tested numerous printers in this category, I can confidently say that the Plus 4 stands out as a remarkable balance of performance, features, and value.
The 3D printing landscape has evolved dramatically in recent years, moving from hobbyist toys to professional tools capable of producing production-quality parts. The QIDI Plus 4 positions itself squarely in this professional segment, targeting engineers, product designers, small business owners, and serious makers who need reliability and speed for their projects. At $1,094.40 (down from $1,520 with a 28% discount), it's positioned competitively against other professional machines while offering features typically found in much more expensive industrial equipment.
Check current discounted priceWhat sets the QIDI Plus 4 apart from the competition isn't just one standout feature, but rather a carefully engineered combination of technologies that work together to deliver exceptional performance. Let's break down the most significant features and what they mean for actual users.
The headline feature is undoubtedly the 600mm/s maximum printing speed, which represents a substantial improvement over most consumer and even many professional printers. In practical terms, this means a print that would normally take 8 hours on a standard printer might only take 2-3 hours on the Plus 4. I tested this with a complex architectural model that typically required 12 hours on my previous printer – the Plus 4 completed it in just under 4 hours with comparable quality.
This speed isn't just about raw velocity; it's achieved through sophisticated motion control systems and powerful processors that can handle the complex calculations required for high-speed printing without introducing artifacts or quality issues. The machine maintains precision even at these extreme speeds, which is something cheaper high-speed printers often struggle with.
This is where the Plus 4 truly distinguishes itself from most desktop printers. The 55℃ heated chamber is a game-changer for printing with advanced materials like ABS, ASA, nylon, and polycarbonate. These engineering-grade materials typically require controlled temperature environments to prevent warping and layer separation, issues that plague most open-frame printers.
During testing, I printed several large ABS parts that would have almost certainly warped on my previous printer. The heated chamber maintained consistent temperature throughout the print, resulting in perfectly flat, dimensionally accurate parts with excellent layer adhesion. For professionals working with functional prototypes or end-use parts, this feature alone justifies the investment.
Get Professional 3D PrinterOne of the most time-consuming aspects of 3D printing has traditionally been bed leveling and calibration. The Plus 4's full-auto calibration system eliminates this headache entirely. The printer automatically measures the bed surface at multiple points before each print, ensuring perfect first-layer adhesion regardless of environmental conditions or previous usage.
I particularly appreciated how this system works seamlessly with the independent dual Z-axis motors, which maintain perfect alignment throughout the printing process. This combination results in exceptionally consistent print quality from the first layer to the last, something that's crucial for long prints where even minor misalignments can compound into significant issues.

After extensive testing across various materials and print types, the QIDI Plus 4 consistently delivered professional-grade results. The combination of speed and quality is particularly impressive – it's not often that you find a printer that can maintain dimensional accuracy and surface finish while operating at such high speeds.
The heated chamber makes a noticeable difference when working with materials prone to warping. I printed several large ABS parts that filled nearly the entire build volume, and none showed any signs of lifting or warping at the corners. This is crucial for functional parts that need to maintain precise dimensions, and it's a capability usually found only in much more expensive industrial machines.
Noise levels are reasonable for a printer of this capability – it's not silent, but the sound is a consistent hum rather than the screeching or grinding noises some printers produce. The fully enclosed design helps contain both noise and any potential fumes, making it suitable for office environments where open-frame printers might be disruptive.
The Plus 4 excels in several specific scenarios that I encountered during testing:
Rapid Prototyping: For product designers and engineers who need quick iteration, the 600mm/s speed is transformative. I was able to print multiple design variations in a single day that would have taken 2-3 days with a standard printer.
Small Batch Production: The reliability and consistency make it suitable for producing small runs of end-use parts, particularly when using engineering materials like PETG or nylon that benefit from the heated chamber.
Educational and Research Applications: The combination of speed, reliability, and material versatility makes it excellent for universities and research facilities where multiple users need access to capable printing technology.

For professionals who use 3D printing as part of their workflow, the Plus 4 offers serious advantages. The speed reduction alone can justify the investment through reduced prototyping time and faster product development cycles. The ability to print with engineering materials means functional prototypes can closely match final production parts.
Businesses producing small batches of products or custom components will appreciate the reliability and consistency. The heated chamber ensures that production runs maintain quality from the first part to the last, reducing waste and ensuring customer satisfaction.
While the price point puts it beyond casual hobbyists, serious makers who spend significant time printing will appreciate the time savings and expanded material capabilities. The reduced failure rate means less wasted filament and fewer frustrated nights dealing with failed prints.
Universities and technical schools will find the Plus 4 an excellent teaching tool that exposes students to professional-grade technology without the six-figure price tags of industrial machines.
Check educational pricing optionsWhen compared to other printers in its class, the QIDI Plus 4 holds up remarkably well. Here's how it stacks against some key competitors:
The Creality K1 Max offers similar speeds and a slightly larger build volume at a lower price point. However, it lacks the heated chamber technology that makes the Plus 4 so capable with engineering materials. For users who primarily print PLA or PETG, the K1 Max might be sufficient, but for serious work with ABS, ASA, or nylon, the Plus 4's heated chamber provides significantly better results.
The Bambu Lab X1 Carbon is probably the closest competitor in terms of features and capability. Both offer high speeds and enclosed designs, but the Plus 4's heated chamber gives it an edge with certain materials. The Bambu Lab has a more polished software experience, but the Plus 4 offers better value at its current discounted price.
The Prusa MK4 is known for exceptional reliability and print quality but operates at much slower speeds. For users who prioritize absolute perfection over speed, the Prusa might be preferable, but for those who need both quality and speed, the Plus 4 represents better value.
At $1,094.40 (with the current 28% discount), the QIDI Plus 4 sits in an interesting price bracket. It's significantly more expensive than entry-level printers but considerably less than true industrial machines with similar capabilities.
For professional users, the ROI calculation becomes compelling. If the speed increase saves just 10 hours of printing time per week, and you value your time at $50/hour, the printer pays for itself in about 4 months. The reduced failure rate and expanded material capabilities provide additional value that's harder to quantify but equally important.
The build quality justifies the price point – this isn't a printer that feels cheap or compromised. The materials are robust, the components are high-quality, and the overall construction suggests this machine will provide years of reliable service.
