INTRODUCTION

    Over the past decade, 3D printing has evolved from a niche prototyping tool into a cornerstone of modern manufacturing. What began as slow, single‑material experimentation has matured into a field defined by precision, speed, and versatility. Today’s 3D printers can handle multiple filaments, complex geometries, and even color transitions with remarkable accuracy, a testament to how far additive technology has come. Standing at the forefront of this evolution is the brand new QIDI Max 4 Combo, a system built to merge industrial capability with desktop accessibility.

    Our story formed in 2014, QIDI Tech began with a small team of engineers with a big vision: we wanted to make 3D printing accessible to everyone. Crazy? A little bit. With our journey have consistently focused on more than just producing machinery; it's about enabling creators of all kinds to bring their ideas to life. Every day, we're doing more than just constructing printers. We are establishing an environment where seasoned designers and adventurous individuals can join forces, work together, realize ideas, and develop. QIDI Tech 3D printers are created to be intuitive and efficient, after all, delivering a hassle free printing process for all users from the beginning should be the top priority. Our extensive manufacturing plant and advanced research and development center embody our commitment to creativity, excellence, and teamwork.

    The Max 4 Combo by QIDI is built around a rigid CoreXY architecture designed for high‑speed stability, pairing FOC closed‑loop stepper motors with high‑hardness linear guides and 12mm steel shafts to maintain precision even at accelerations up to 30000mm/s² and print speeds reaching 800mm/s. Its 370°C high‑temperature hotend and 65°C actively heated chamber open the door to engineering materials like PA, PC, ASA, and carbon‑fiber composites, while the hands‑free load‑cell leveling system ensures consistent first‑layer accuracy across the large 390x390x340mm build volume. Cooling is handled through a multi‑stage system with PWM‑controlled fans and RPM feedback, and the Polar Cooler extruder cooler adds a dedicated high‑flow channel for long, heat‑intensive prints. With AI camera monitoring, input shaping, power‑loss recovery, and compatibility with the QIDI BOX for automated multi‑color printing, the Max 4 Combo positions itself as a high‑temp, high‑speed platform ready for demanding workflows.
