Description
The QIDI X-Max 2 (X-Max II) is an enclosed large-format FDM printer from 2021 built for engineering prints in high-temperature materials. It's an updated take on the popular X-Max, with the key change being two swappable third-generation dual-gear extruders. It targets experienced users and small workshops that need to print not just PLA and ABS, but also nylon, polycarbonate, and carbon fiber composites.
The build volume is 300x250x300 mm. The motion system is cartesian: a direct drive print head moves across the X and Y axes. It ships with two swappable extruders — a standard Extruder A (up to 250 °C for PLA, ABS, PETG, TPU) and a high-temperature Extruder B (up to 300 °C for nylon, polycarbonate, and carbon fiber). The heated bed reaches around 100 °C, layer height runs from 0.05 to 0.2 mm, and the nozzle is 0.4 mm. Print speed is 30–150 mm/s. An industrial dual Z axis with two motors and 12 mm rails keeps things stable. The enclosure is fully closed with a clear acrylic lid to hold heat, plus a dual-sided PEI plate, a 5-inch touchscreen, a filament runout sensor, power loss recovery, and Wi-Fi, LAN, and USB connectivity.
Advantages
- High-temp printing — the 300 °C Extruder B and enclosed body handle nylon, polycarbonate, and carbon fiber; owners have printed complex ABS models over 12 hours with no defects
- Enclosed chamber — hot air from the feed path plus the acrylic lid hold heat (around 59 °C inside during ABS prints), so parts don't lift off the bed from drafts
- Dual-gear extruder — the third-gen dual-gear assembly delivers more feeding torque and fewer clogs than the single-gear unit on the original X-Max
- Magnetic dual-sided PEI plate — textured and glossy sides on a flexible removable surface; ABS sticks without glue and pops off easily
- Industrial dual Z axis — two motors and 12 mm rails keep the bed level and stable on large parts
- Ready out of the box — ships mostly assembled with a spare extruder, a toolkit, and a thorough manual; setup takes about 10 minutes
Disadvantages
- Not true multi-material — the two extruders are swappable, not simultaneous, so you can't print two materials in one model
- Bulk and weight — the 580x510x550 mm body at around 28 kg takes a lot of space for its build volume and is hard to move
- Modest electronics — the 5-inch touchscreen isn't very responsive, and the proprietary board makes firmware updates and OctoPrint hookups difficult
- Slow by modern standards — 30–150 mm/s is noticeably slower than newer CoreXY machines, so big models take a long time
The QIDI X-Max 2 suits experienced users and small workshops that need an enclosed, large-format machine for functional parts in ABS, ASA, nylon, polycarbonate, and composites. It's a workhorse for engineering prints, not a speed or multi-color machine.
Bottom line: the X-Max 2 is a reliable enclosed printer for high-temperature materials with a large build volume. Its strength is stable printing in demanding plastics; its weak spots are the dated electronics and slow-by-today's-standards speed. The model is now discontinued, replaced by the CoreXY X-Max 3.
