Review: Must have for high volume engineering filament use - Uses: Primarily PPA-CF and ABS-CF for aerial drone applications. Pros: Outstanding print quality. Handles engineering filaments like butter. The value is insane with what this machine does. Almost 100% open source. Dedicated slicer (QidiStudio), but still compatible with other slicers. Clean, user friendly operation. Cons: Pre-print start time is lengthy, but of course it is, the machine is massive. High filament purge amounts, but it's open source so that's easily remedied. Software and UI is a bit choppy, but Qidi engineering is actively improving its products. Initial power consumption is high, but it levels out once printing is active. This can be mitigated by throttling start times for high energy demand projects (Preheating the bed, using nozzle temp and bed temp to reach chamber temp, etc). Full disclosure: I received my machine with a warped bed. However, I had a new one in a couple of weeks and swapped it in a couple of hours. This is where Qidi really shines. Having the right to repair is a vanishing privilege in 3D printing spaces. 3D printers are complex machines, and having a mostly open source machine with easily sourced parts, where the company's support team actively engages its customers and GUIDES them through repairs, that is imho, the most valuable asset Qidi has. I also own a Q2 combo, several hundred hours so far. The Max4 is a welcome addition to our growing print lab. And I can't stress enough how problem solving and tinkering are a huge part of 3D printing. Maintenance and care is necessary to keep your machine running well. So, If you need/want a powerful, large, reliable machine that can crank out some quality prints, you found your new favorite toy.
Review: Easy set up, great quality. - UPDATE. I still give this a 5 syar. Ive been printing woth it for a while now, 700 hours or so. I have had minimal issues and they were settled quickly and efficiently by CS. Id like to call out Linda. She was very helpful and pleasent with my camera issue. She got me the right infor to get it working again without needing parts. This company has been nothing but spot on as have their printers This a huge and excellent machine. Aside from the size, set up is easy. Even someone with no experience should have no issues. Follow the on screen prompts on the machine and it walks you through everything. Build quality is excellent. Little details and quality of life features in everything from a proper driver to remove packing screws to the status bar led in the base of the build plate. This machine is well thought out and also just plain looks good. The Qidi Box is easy to hook up as well. No issues there. First prints out of the box (waste chute and bin) with generic PETG settings came out fantastic. I am looking forward to doing large multi color prints in all materials. This thing is a beast in all the best ways. LOVE IT. This is my second try at leaving a review. Not sure if the first one went through or not. If I end up with two on here, sorry.

## Questions & Answers

**Q: How much space does the printer require?**
A: QIDI Max4 external dimensions: 558×578×612 mm, shipping dimensions: 700×710×750 mm; we recommend leaving extra clearance at the back, sides, and top for easier filament changes and better ventilation and cooling.

**Q: How can I connect the printer?**
A: The QIDI Max4 supports flexible connections including QIDI Cloud for remote control, 2.4GHz/5GHz Wi-Fi, Ethernet for stable local networking, and offline printing via USB drive.

**Q: What Makes the MAX4 Stand Out?**
A: 390x390x340mm build volume, 370°C high-temperature hotend, and an actively heated chamber up to 65°C. Designed for engineering materials like PC, Nylon, and CF composites, it ensures industrial-grade stability and high-speed printing up to 800mm/s

**Q: What materials can it print with?**
A: The QIDI Max4 supports many materials: PLA, PETG, ABS, ASA, TPU, PA, PC, PPS-CF and carbon fiber composites. Its 370°C nozzle and 65°C heated chamber ensure stable printing for standard and engineering-grade materials, offering full creative freedom.

**Q: What is the maximum print speed?**
A: The QIDI Max4’s tool head reaches up to 800 mm/s and 30,000 mm/s² acceleration. Actual print speed depends on material and flow rate; high-speed PLA and ABS reach around 30 mm³/s. QIDI will launch a high-flow nozzle later for even faster printing

### ⭐⭐⭐⭐⭐ QiDi 4 Max - No fuss printing with great features
*by A***R on April 12, 2026*

I’ve been using the QiDi 4 Max 3D Printer with the 4 color combo box, and it’s been an excellent experience overall. Print quality is outstanding. Layer lines are clean, details are sharp, and results look professional with minimal tuning. Speed is equally impressive, delivering fast prints without sacrificing quality, which makes larger or multi part projects much more efficient. The large build volume is one of the biggest advantages. Not being limited by size feels incredibly freeing and makes it easy to take on bigger projects without splitting models. Compared my previous print, the Prusa i3 MK2, the build quality here feels much more solid. I was nervous the print quality would not be able to match the Prusa but I am happy report it is just as good if not better. The features and enclosed printing are above and beyond what I expected for a printer in this price range, and the ability to reach high temperatures opens the door to high strength materials, making it an engineer’s dream. The 4 color combo box adds great flexibility for multi color prints without making things overly complicated. Overall, this setup delivers an excellent balance of speed, quality, and capability at a fantastic cost point. I would not hesitate to purchase this printer again
