QIDI Max 4 (X-Max 4) Review – Incredible 3D Printer With Serious Issues

Описание: 👉Qidi Max 4 (also known as the X-Max 4) is one of the most ambitious enclosed CoreXY 3D printers released by Qidi Tech. But after two months of testing, airflow measurements, power analysis, thermal mapping and real performance testing, I discovered both incredible strengths… and some serious design issues that need addressing.

In this full 1 hour 43 minute engineering deep dive, I break down the Qidi Max 4 with real-world testing including airflow analysis using an anemometer, infrared heat testing of the build plate, power consumption measurements, sound testing, firmware updates and high-speed performance observations.

This review is not sponsored editorial content — it is independent, data-driven testing designed to provide honest feedback for both the maker community and Qidi engineers.

While the Max 4 is capable of excellent performance, there are also design limitations affecting auxiliary cooling and high-speed printing behaviour that need attention. I explain exactly what these issues are, why they occur, and how both firmware improvements and community engineering solutions could potentially turn this machine into a true powerhouse.

Overall, the Qidi Max 4 earns an 8.5 / 10 rating in its current state — but with a few improvements it could easily become a 10 / 10 engineering-grade machine.

If you want real testing instead of marketing hype, this video is for you.
