Description
The QIDI X-Max is an enclosed desktop FDM printer from 2019 with a large build area that ships fully assembled. It was aimed at users who need a big volume and out-of-the-box engineering material printing, just not at CoreXY speeds. The model is now discontinued, but it remains well known from reviews and still turns up on the used market.
The build volume is 300x250x300 mm. The kinematics are Cartesian: the print head rides on a 10 mm steel rod, and the Z axis uses two independent lead screws with their own motors. Speed is modest by today's standards, around 60 mm/s in normal use and up to 150-180 mm/s at the top end. It comes with two swappable direct drive extruders: a standard one with a PTFE liner rated to about 250 °C (PLA, ABS, PETG, TPU) and an all-metal high-temp unit good for 300 °C (nylon, polycarbonate, carbon fiber). The bed is aluminum with embedded magnets and heats to 120 °C, the housing is fully enclosed, and you get a 5-inch touchscreen, Wi-Fi, LAN, and power loss recovery.
Advantages
- Enclosure and 120 °C bed — ABS and ASA print without warping straight out of the box, which was rare at this price in 2019
- Two swappable extruders — a standard unit for PLA/ABS/PETG/TPU and an all-metal 300 °C one for nylon, polycarbonate, and carbon fiber, swapped to suit the job
- Dual-sided magnetic bed — textured and glossy surfaces, and prints pop off by flexing the plate, no scraper needed
- Quiet operation (rated ~50 dB) — silent stepper drivers make it livable in a shared room
- Easy to start — assisted bed leveling and a solid first layer right after unboxing, and the machine arrives assembled
- Power recovery and air filtration — printing resumes after a power outage, and two exhaust fans with filters cut down the ABS smell
Disadvantages
- Bulky print head — it blocks the view of the print start, especially on small parts, and makes fishing dropped objects out of the chamber awkward
- Closed electronics — the Cura-based QIDI Print and proprietary board make alternative firmware hard to flash, and there's no OctoPrint over USB
- Poor USB port placement — the port on the lower front panel is easy to bump with your foot and damage
- Heavy and large — roughly 27 kg and 580x530x740 mm, so it needs a sturdy desk and real space
The QIDI X-Max suits anyone who wants an enclosure and a large build area for functional parts in ABS, nylon, and polycarbonate, and who isn't chasing high speeds. It's a workhorse for small shops and engineering jobs rather than fast or multi-color printing.
Bottom line: the X-Max is a solid enclosed printer of its era with an honest feature set for engineering materials. Its strengths are the big volume and the two extruders for different plastics; its weak spots are the low speed, closed ecosystem, and serious weight.
