QIDI Plus5: problems, parts and running costs

Checked: 2026-10-19

Summary

The QIDI Plus5 is a large-format enclosed CoreXY 3D printer (320×320×300 mm) with a 550 W chamber heater holding up to 65°C, built for ABS, PC, PA and carbon-fiber filaments at a consumer price. [1] What usually goes wrong is the optional QIDI Box multi-color system — Tom’s Hardware says it “still doesn’t work” — plus awkward rear filament loading and chamber-heat clogs with PLA and PETG. [3][5][8] Running costs are filament, electricity (190 W steady-state on PLA, 500 W on ABS), replacement air filters and replacement nozzles; at $749 from QIDI’s US store it is a compelling buy for engineering filaments, with long-term reliability unknown since the printer launched in August 2026. [1][2][4]

Common problems and fixes

QIDI Box multi-color system unreliable — Tom’s Hardware states it “still doesn’t work”, and 3DWork reported occasional QIDI Box and cloud sync issues. Without the QIDI Box the printer also cannot detect filament jams. Fix: run single-color until the ecosystem matures; the Box is optional and sold separately. [3][5]
Chamber-heat clogs with PLA and PETG — a Reddit thread reports PLA and PETG clogging the nozzle when the chamber runs too hot without active cooling or extraction. QIDI advises setting chamber temperature about 10°C below the filament’s softening point. [8][12]
SSR issues on 110 V units — one Reddit user reported “burning bed SSR’s”, mainly a 110 V issue. The sibling Plus4 had a documented 110 V inductor aging issue under extended full-load operation, for which QIDI shipped replacement boards and extended the warranty; no equivalent issue is reported for the Plus5 yet. [8][11]
Software glitches — occasional Klipper issues and QIDI Maker app bugs, including incidents where the app unbinds the printer from your account. Cloud outages also cause occasional sync issues. [4][5]
AI camera limited out of the box — the camera defaults to 640×480p; accessing the native 1920×1080p requires manually editing crowsnest.conf through the web interface. [4]

Parts and consumables

QIDI Box (optional) — up to 16 colors with four boxes; the Combo package with QIDI Box is $899 from QIDI’s US store, checked October 2026. Max4-model boxes work directly; Plus4 or Q2 boxes need a QIDI Box Hub and Signal Cable. [1]
Polar Cooler (optional) — active toolhead cooling; the Polar Cooler bundle is $849 from QIDI’s US store, checked October 2026. [1]

Yearly running cost

The sources do not publish prices for replacement filters, nozzles or electricity rates, so no total yearly figure can be computed from them. What a typical owner buys: filament as the main cost; replacement air-filter cartridges; replacement nozzles when printing abrasive carbon-fiber materials; and electricity — the printer draws 190 W steady-state on PLA and 500 W on ABS, from a maximum of 150 W main + 550 W chamber + 500 W bed. No subscription is mentioned for the printer; QIDI Studio ships on the included USB stick. [1][5][9]

When it is a good buy

$749 at QIDI’s US store, checked October 2026 — the standard variant (SKU PLUS5001); a compelling package for engineering filaments, with the 65°C heated chamber as the main differentiator. Launch price was $749, with a member discount bringing it under $700. [1][2]
Above $900 — weak value; at that price the Bambu Lab P2S or other alternatives with proven multi-color ecosystems and deeper owner histories become competitive.
Alternative: Bambu Lab H2S at $1399 — Tom’s Hardware says the Plus5 “gives Bambu Lab a run for its money” at nearly half the H2S price; the H2S is the better choice when you want a proven multi-color ecosystem and a deeper owner history. [3]
