QIDI Plus5 Review: The Best Mid-Size Enclosed Printer Right Now

A Bigger, Bolder Plus Line

The QIDI Plus 4 earned its reputation the hard way: by simply printing, hour after hour, without drama. After more than 1,000 hours of flawless output in one reviewer's workshop, it became the printer people recommended when someone asked for a reliable enclosed CoreXY. The Plus 5 had to top that. QIDI shadow-dropped the machine earlier this year, and after over 100 hours of testing, the verdict is clear: it is the best mid-size enclosed printer on the market right now.

The Plus 5 keeps the fully enclosed metal frame and CoreXY kinematics but upgrades almost every system that mattered on the Plus 4. The build volume expands to 320 x 320 x 300 mm. That extra 20 mm of height and slightly wider bed make large cosplay armors, multi-part assemblies, and tall prototypes noticeably less precarious than before.

Polar Cooler Solves the Heat Creep Problem

Heated-chamber printers have always faced a specific enemy: heat rising toward the extruder and causing jams during long ABS or polycarbonate sessions. QIDI attacks this with the Polar Cooler, an active toolhead cooling system that acts like a miniature air conditioner for the hotend. Combined with a 550W chamber heater, the Plus 5 keeps the print area at 65C while the extruder stays stable enough to run for hours without skipping a beat.

The hotend itself reaches 370C and pushes up to 40 mm³/s of flow. That opens the door to PPS-CF, PA-CF, PC, and other engineering materials that cooked the Plus 4's hotend over long runs. A full-coverage silicone bed replaces the older spiral trace design, eliminating the cold spots that caused first-layer grief on large ABS prints.

Setup, Software, and Day-to-Day Use

Unboxing the Plus 5 is straightforward: the guided on-screen setup walks you through securing the gantry, tramming the bed, and loading filament. No QR code scavenger hunt, no 90-page PDF. The 4-inch touchscreen runs a refreshed interface, and QIDI Studio (Orca/PrusaSlicer-compatible) handles slicing. Klipper runs underneath with a Fluidd-like web interface for users who prefer browser control.

In testing, the Plus 5 produced zero failed prints, zero clogs, zero calibration drift across PLA, PETG, ABS, and ASA. The 1.5GT belts and upgraded linear rails deliver cleaner X-axis lines, and the load-cell bed leveling nails first-layer adhesion on the first try.

How It Stacks Up

The Plus 5's direct competitors are the Creality K2 Pro and K2 Plus and the Anycubic S1 Max. The K2 Pro maxes out at 300C hotend temperature. The K2 Plus reaches 350C. The Plus 5's 370C head gives it a real edge if you want PPS-CF or other exotic engineering materials. The S1 Max matches the Plus 5 on paper but runs CrealityOS on top of Klipper, which some users find restrictive.

At launch, the Plus 5 Combo (printer plus the multi-color QIDI Box) costs $899. The standalone printer is $749, or $699 before August 31 for existing QIDI owners. That is the same launch price as the Plus 4, which feels like a gift given inflation across the rest of the market.

Verdict

The QIDI Plus 5 is not an incremental refresh. It is a new platform built around the lessons from 1,000-plus hours of Plus 4 field use. The Polar Cooler, the hotter hotend, the cleaner motion system, and the bigger bed all address real pain points. For anyone buying an enclosed CoreXY for technical filaments today, the Plus 5 should be at the top of the list. It is the most complete enclosed mid-size printer available, and QIDI held the price line while raising every meaningful spec.
