Large Fully Enclosed CoreXY 3D Printer (Qidi Tech X-Max 3)

Overview

In recent times, the popularity of Core XY 3D printers has significantly increased, prompting many major manufacturers to enter this market space. Among these companies is Chiti Tech, a brand recognized for its fully enclosed box frame 3D printers since 2014. Their latest venture into the Core XY format with the release of three new models was ambitious, particularly as they encountered some initial setbacks with the larger models, the X+ and X Max 3. However, after a period of reevaluation and improvements, these models were reintroduced to the market.

Design and Build Quality

The X Max 3, which is the focus of this review, is a large, fully enclosed, Core XY 3D printer. It boasts a substantial build volume of 325x325x315 mm and is constructed primarily from steel, with a bulky plastic exterior, contributing to its sturdy build. The printer's design necessitates a sizable dedicated space due to its footprint and weight. It features several user-friendly design choices, like exterior handles for easier lifting and an integrated flex plate system with a powder-coated PEI surface for improved adhesion.

Hardware and Performance Updates

Significant improvements have been made to the X Max 3's hardware, addressing earlier issues around thermal expansion and consistency in print quality. The printer now features an entirely metal interior frame and sports hollow steel rods on the X-axis for increased rigidity and low maintenance. Alongside these hardware upgrades, the printer comes equipped with a direct drive extruder and an all-metal hotend, suitable for a wide range of materials including high-temperature ones.

Software and Connectivity

The X Max 3 runs on Clipper firmware and includes wireless printing capabilities via an included Wi-Fi dongle, though the placement of its full-size USB port for flash drives could have been more conveniently located. The printer's interface is managed through a 5-inch touchscreen, providing a mostly smooth user experience despite some minor navigational delays.

Printing Experience

The printing experience with the X Max 3 is largely positive, benefiting from the improved structural design and firmware tweaks. It demonstrates a strong ability to handle various materials, supported by its enclosed chamber with a heater, direct drive system, and capable cooling fans. However, certain aspects such as the spool holder's placement and the reliance on a BL touch for bed leveling could pose minor inconveniences. Adjustments within the slicer settings might be necessary to balance speed and print quality optimally.

Pros and Cons

The X Max 3 is competitively priced, considering its feature set and print quality. Its sturdy construction, versatile material compatibility, and solid customer support from Chiti Tech are commendable. Yet, it's not without its shortcomings. Its bulky design demands considerable space, and some design choices regarding the spool holder and USB port could have been better thought out. Furthermore, while the BL touch is a reliable component for many, alternative bed leveling solutions might have offered a more consistent performance within the printer's enclosed environment.

Conclusion

The Chiti Tech X Max 3 stands out as a solid choice for those in need of a large, fully enclosed Core XY 3D printer, capable of handling a wide range of printing tasks. While it shows significant improvements over its initial release, there remains room for refinement, particularly in design ergonomics and user interface elements. For enthusiasts and professionals alike, the X Max 3 represents a considerable investment into high-quality, versatile 3D printing capabilities, with the caveat that some may find the need to implement minor modifications for an optimized printing experience.
