Who this is for
If you are a first-timer, setup will not defeat you; the machine is quick to first print and forgiving on PLA and PETG. Just know that the engineering materials that make it worth the price bring drying, tuning, and calibration work you grow into rather than get for free. For an upgrader, the Plus4 adds a sealed, actively heated chamber, a hardened nozzle, and a real engineering-material range, with optional multi-color if you want it, though the multi-color is single-nozzle and purge-based, so swaps are slow, wasteful, and not a substitute for true multi-material work. For a prosumer, it is reliable and durable enough to run, but the weak support pattern, partial parts availability, and slowing firmware are the risks to price in, partly offset by the ability to fall back on stock Klipper and open slicers. The ceiling is clear: strong capable hardware, uncertain long-term backing. The machine is good. The moment is the problem. Given the successor window and softening firmware support, hold off and watch for either a new model or a price drop before you buy, unless you find the printer discounted enough that the timing risk is already paid for.
PrintSignals Review
QIDI Plus4 Review
Written by AI from manufacturer specifications and the aggregated consensus of
PrintSignals does not test printers hands-on. How we do this
Assessment
The QIDI Plus4 is a fully enclosed, actively heated-chamber printer built for engineering-grade materials, with optional single-nozzle multi-color on the side. At around €700 it undercuts most machines that can run the same material list, and the tracked reviewer consensus is genuinely strong: fast, accurate, reliable in practice, and good value for what it costs. This is not a weak machine, and nothing below should read as if it were. The reason PrintSignals lands on WAIT is timing, not quality. QIDI turns over its lineup on roughly a two-year cadence, and the Plus4 is now inside the window where the brand typically announces something new. A successor is not confirmed, but the firmware update cadence has already slowed to somewhere in the six-to-twelve-month range, which is the kind of signal that tends to precede a model transition. If you buy today, the risk you are taking is a newer model or a real price cut landing shortly after. Watch for a successor announcement and for the printer-only price sliding before you commit.
Build and print volume
You get a 305 x 305 x 280 mm build area, a medium footprint that handles most functional parts, brackets, and mid-size enclosures without forcing you to section a model. The more important hardware fact is the enclosure. It is fully sealed and the chamber is actively regulated up to 55°C, which is the piece that actually makes reliable ABS and ASA printing possible rather than a gamble. Open-frame machines can attempt those materials but fight warping and layer splitting on anything sizeable; the contained, heated chamber here is what widens the reliable range. The hotend reaches 370°C and the bed 100°C, which is enough headroom for the high-temperature end of the supported list rather than just the easy materials.
Material capability
The supported range is broad: PLA, PETG, PHA, PVB, ABS, ASA, HIPS, PA (Nylon), PC, PP, and PPS all fall inside it, and reviewers rate material handling across that range as good in practice. The stock nozzle is hardened steel, so abrasive filaments are covered too, including CF and GF variants, ABS-CF, ASA-CF, PA-CF, PC-CF, and PP-CF, without a nozzle swap. The direct drive extruder makes flexibles workable, with TPU the most forgiving and TPE, TPC, and PEBA reachable as tuning demands climb with each. What the printer supports and what runs effortlessly are two different things. PLA and PETG will behave from the start. The engineering materials that justify buying this machine, Nylon, PC, and the carbon-filled blends, need filament drying, careful temperature management, and calibration patience, and that overhead tends to surface only once you push past PLA, not during setup. The capability is real; treat the harder materials as a skill you build into, not a switch you flip.
Setup and ownership
First print is genuinely quick. The Plus4 ships near-fully assembled, typically under 15 minutes to first print, with assisted bed leveling, automatic Z-offset, automatic first-layer calibration, and runout and failure detection handling the fiddly parts. Reviewers consistently describe it as accessible to set up and live with day to day, and that holds. The intermediate rating comes from the firmware model underneath: this is modified Klipper, minimally abstracted, so tuning, calibration, and debugging are ongoing parts of ownership rather than a one-time chore, especially as you move into the demanding materials. In use it is quiet for its class and reliable, though clogs show up occasionally as normal maintenance, and fumes are noticeable enough that a ventilated space is not optional. It prints noticeably faster than typical machines in its class at excellent quality, but the two pull against each other at the top of the speed range, so quality-critical work needs slower settings. One thing to diagnose around: error messages are generic text or raw firmware output with no structured code system, so you are on your own to interpret faults. The manufacturer's slicer, QIDISlicer, rates well and is Orca-based; OrcaSlicer is officially supported too, so you are not locked to one toolchain. The printer alone runs around €700, and the optional multi-spool system brings it to roughly €850.
Support and longevity
This is where the WAIT verdict gets its weight. QIDI's support pattern is on the weak-to-short side. Spare parts are only partially available through official channels, meaning some common wear items can be sourced and others may not be. The manufacturer has generally acknowledged hardware issues publicly, but the resolution outcomes owners report have been inconsistent, so a known problem getting fixed is not something to count on. Against that, the machine itself holds up: reports describe it as durable over extended use with no notable component degradation, and maintenance is rated manageable with clear procedures. The ecosystem hedge matters more than usual here. Because the firmware is modified Klipper and the community can install stock Klipper, and because third-party slicers are accepted, you are not fully dependent on QIDI continuing to support the machine to keep it running as it ages. For a prosumer weighing this as a business tool, that semi-open setup is the thing that softens the lifecycle risk, but the slowing firmware and partial parts supply are real and should factor into how long you expect first-party backing to last.
