QIDI X-Plus 3 Review: An Enclosed CoreXY Built for Engineering Filaments

The verdict, up front

The QIDI X-Plus 3 is a 2023 enclosed CoreXY printer with a 280×280×270 mm build volume, a 350°C hotend, a 120°C bed and an actively heated chamber up to 65°C, all running on stock Klipper. It isn't built for pretty figurines — its whole point is functional parts: fast, reliable printing of ABS, ASA, polycarbonate, nylon and carbon-fiber composites.

Buy it if you need an actively heated chamber and a large bed for engineering filaments and you can live with the noise and a laggy interface. If you mostly print PLA and PETG in a living room, you're paying for capabilities you won't use — a quieter open bed-slinger or the newer QIDI Q1 Pro makes more sense.

Specifications

Unboxing and what's in the box

The printer ships about 95% assembled — unbox it, cut the shipping ties, mount a spool and you're ready to print. Packaging is solid: double foam, plastic wrap and a carry-handle box (it weighs 19.5 kg). Inside you get the flexible magnetic PEI bed already installed, the built-in filament dryer, a scraper, glue stick, tool and spare-parts kit, plus a spare hotend and a 500 g sample spool of UltraABS-GF25.

A nice touch: QIDI includes two hotends — a copper one for regular plastics and a hardened steel one for abrasives. Print carbon- or glass-filled composites and the steel nozzle won't wear out after a couple of spools. Manual and slicer profiles live on a USB stick. Build quality is sturdy overall but not premium: the enclosure plastic is plain, and the acrylic door wobbles noticeably when you open it.

Under the hood: motion and hotend

It's a CoreXY at heart, with dual independent Z motors and a pair of hardened carbon-fiber rails on the X axis. The print head is light, with a direct-drive extruder and a 9.5:1 gear ratio — plenty of torque to spare, and flow up to 35 mm³/s. The ceramic-heated hotend hits 200°C in about 29 seconds. An ABL probe next to the nozzle maps the first layer across 16 points before every print.

There's a built-in filament dryer at the back — rare at this price. The spool sits in a sealed compartment with a desiccant bag so it won't soak up moisture during long prints. That matters most for nylon and PETG, which hate moisture. The one catch: the carbon rails need wiping down and lubrication every 1–2 weeks or you'll get ringing on the walls, and swapping the hotend is a bit fiddly.

Print quality

Out of the box it prints clean. A test 3DBenchy takes 14–17 minutes and comes out crisp even at speed; in Basic Tutorials' independent test, print quality scored 94 out of 100. Walls are smooth, detail is good, layers stack evenly. On tricky geometry with long overhangs you'll sometimes see faint ringing, some under-extrusion and stringing — but that's a profile tuning issue, not a machine defect.

The X-Plus 3's strong suit is high-temp printing without warping. Reviewers call out the even bed heating in particular: a thermal camera shows nearly uniform temperature across the whole surface, with no cold corners. Paired with the 65°C chamber, that gives consistent adhesion and minimal delamination on ABS and polycarbonate. A few PLA and PETG colors still needed a glue stick for reliable first-layer grip.

Speed, temperatures and noise

Speed is genuinely high: QIDI advertises up to 600 mm/s and 20,000 mm/s² acceleration, while real prints land around 200–300 mm/s depending on material. Heat-up, though, is slow: the bed reaches 60°C in about 2.5 minutes and 100°C in nearly 7.5 minutes, and the chamber takes 8–9 minutes to hit 65°C. Board boot-up and UI responsiveness are also on the sluggish side.

The number-one complaint about the X-Plus 3 is noise. The stock fans run at 100% and howl; the community has dubbed it one of the loudest printers around, and there's even a dedicated YouTube video on taming it. Putting this machine in a quiet living room is uncomfortable — it belongs in a workshop, garage or a separate room. The good news: the noise is fixable, and plenty of owners swap in quiet fans and tweak the cooling curves.

Materials: the engineering strong suit

This is why people buy the X-Plus 3. The combination of a 350°C nozzle, a 120°C bed and an actively heated 65°C chamber reliably handles ABS, ASA, polycarbonate, nylon and PA12-CF/PET-CF composites. Walls don't split, parts don't curl. Don't expect miracles, though: 3DToday notes that even inside the enclosure, nylon still needs temperature and speed tuning — it's a fussy material by nature. Below are ballpark temperatures (pull exact profiles from QIDI Slicer or OrcaSlicer):

One safety note: despite the enclosed chamber, the X-Plus 3 has no built-in air filtration (no HEPA or carbon filter). Printing ABS and composites releases fumes and VOCs, so you'll want external extraction or a well-ventilated space.

Software and ecosystem

This is QIDI's ace card — openness. The printer runs stock Klipper with resonance compensation, so it isn't locked into a proprietary cloud. Slice in QIDI Slicer, or in OrcaSlicer, Cura, PrusaSlicer or Simplify3D — QIDI officially publishes Orca profiles. For web control, spin up Fluidd or Mainsail: the QIDI interface opens at the printer's IP on port :10088. There's even SSH access to the board (default password: makerbase), so enthusiasts update Klipper, Moonraker and Fluidd with community scripts and add remote monitoring. Regular users can stick to the QIDI-Link app and print over Wi-Fi, Ethernet or USB.

Pros

• Active 65°C heated chamber + 350°C hotend + 120°C bed — print ABS, ASA, PC, nylon and carbon composites without warping or delamination
• Stock Klipper with resonance compensation: high speed without losing quality, Benchy in 14–17 minutes, clean prints out of the box
• Open ecosystem: OrcaSlicer, Fluidd/Mainsail on port :10088, SSH access, community scripts — not locked to a cloud
• Two hotends included — copper and hardened steel; strong 9.5:1 direct-drive extruder with up to 35 mm³/s flow
• Even bed heating and fast hotend warm-up (200°C in ~29 seconds)
• 95% pre-assembled: flexible magnetic PEI bed, built-in filament dryer, lighting and spare parts
• 280×280×270 mm build volume — noticeably larger than budget bed-slingers, enough for enclosures and functional parts
• Flexible connectivity and slicer choice: Wi-Fi, Ethernet, USB; QIDI Slicer, Cura, PrusaSlicer, Simplify3D, OrcaSlicer

Cons

• Very loud — the stock fans run at 100% and howl; one of the loudest printers in its class, and most owners swap the fans
• Slow to heat: bed to 60°C in ~2.5 min, to 100°C in ~7.5 min; board boot and UI are sluggish too
• Unresponsive 5-inch touchscreen — you have to press firmly
• Wi-Fi drops out periodically, especially during calibration — Ethernet is more reliable
• No built-in air filtration, even though the chamber is enclosed and aimed at ABS — you need external extraction
• Build niggles: a hotend bolt vibrated loose in a week, the door wobbles, and the bed's coating can rub off over time
• Carbon rails need cleaning and lubrication every 1–2 weeks, and the hotend swap is awkward
• It's a 2023 model: QIDI's newer Q1 Pro is quieter, cheaper and has a camera, albeit with a smaller bed

How it compares

Want the same internals but a bigger bed? Look at the larger QIDI X-Max 3 (325×325×315 mm, but 38 kg and pricier; its quirks are covered in a separate known-issues piece). Want the same heated chamber cheaper and quieter? The newer QIDI Q1 Pro adds a camera but shrinks the bed. Its closest rival in spirit is the Bambu Lab P1S: quieter, with a camera and the AMS multicolor system — but its chamber is passive and the nozzle only reaches 300°C, so for pure engineering work the X-Plus 3 is more flexible.

Bottom line

The QIDI X-Plus 3 packs a lot of engineering capability for the money. For ~$599–699 you get an enclosed CoreXY with an actively heated chamber, a 350°C hotend, a 120°C bed and open Klipper — a combo that cost twice as much just a couple of years ago. It prints fast and reliably in exactly the materials open bed-slingers struggle with: ABS, polycarbonate, nylon, carbon fiber.

Its weaknesses are honest and predictable: noise, slow heat-up and a laggy interface. This is a printer for a workshop and functional parts, not for quietly printing trinkets in a bedroom. If your work is engineering filaments and a large bed, and you can put the noise behind a wall or hush it with quiet fans, the X-Plus 3 earns its price. If you want a quiet, hassle-free machine for PLA/PETG, look at the Q1 Pro or the Bambu Lab P1S instead.
