Creality SpacePi X4L: problems, parts and running costs

Checked: 2026-10-18

Summary

The SpacePi X4L is the lite version of Creality’s four-spool SpacePi X4: the same chassis and dual 200 W PTC heaters, but capped at 75 °C instead of 85 °C, with no active dehumidification or one-way sealing valves. [1][4] The complaints owners report most often are a humidity readout that floors around 20 % RH, spools that do not rotate during drying, and lid sealing that varies from unit to unit. [7][9][10] Running costs are electricity only — Creality publishes 0.095 kWh for one chamber and 0.165 kWh for both at 75 °C per hour — and at the $119 US store listing (2026-10-18) it is a good buy for PLA, PETG, TPU and ABS/ASA, but not for filaments that need 80-85 °C. [3][4]

Common problems and fixes

Humidity readout floors near 20 % RH — the most widely reported issue: the display rarely drops below about 20 %, a known limit of the low-cost sensor; one owner logged 23-26 % on the unit against 11 % on an independent hygrometer inside the spool, and another saw PC reach 8 % and PLA sit at 30-40 % once unsealed. [7][9] There is no fix; treat 20 % as the sensor limit, dry longer, or verify with an independent hygrometer. Not a warranty matter.
Spools do not rotate during drying — drying relies on 360° hot-air circulation instead, and the machine cannot feed all four spools simultaneously into CFS-compatible multi-colour printers. [8] Workaround: dry thoroughly first, then feed through a 4 mm PTFE tube as Creality recommends. [1] Not a warranty matter.
Lid sealing is disputed — one X4 owner measured only +2 % RH 36 h after the heating cycle ended, another reports no gasket on the lid with humidity rising to ambient when idle, and a 2026 thread reports humid-air ingress in tropical climates. [10][9][14] The X4L lacks the X4’s one-way valves, so idle humidity ingress is a plausible caution for this model. Fix: after drying, move filament to an airtight container with desiccant. Not a warranty matter.
Touchscreen is low quality — widely described as low quality and not very responsive by owners on Reddit and BestBuy. [9][11] No fix reported; keep firmware current from Creality’s download page. [17] Not a warranty matter.
Nearly empty spools can skew or jam during printing — reported across the X4/X4L chassis; a community-designed clip-in spool guide exists on Printables. [13] Fix: print the spool guide or dry fuller spools. Not a warranty matter.
It does not work as a drybox — owners report chamber humidity rising to ambient when the unit sits idle, and a 2-spool Space Pi owner could not get below 22 % RH. [15][16] Fix: remove filament after drying and store it in an airtight container with desiccant. Not a warranty matter.
75 °C ceiling is too low for PA, PAHT and PC — the X4L is the lite variant and cannot reach the 80-85 °C those filaments call for; it dries them only slowly and incompletely. [4][5] Fix: buy the SpacePi X4, which reaches 85 °C with active dehumidification. Not a defect, so not warranty-covered.

Parts and consumables

No replaceable parts or consumables reported. The desiccant is built in and regenerates through heated airflow, the X4L manual lists 10 reusable silica gel packs and a 1 m PTFE tube in the box, and Creality publishes no service-parts list for the X4L — only firmware downloads and FAQs. [12][17]

Yearly running cost

Electricity is the only recurring cost Creality publishes: 0.095 kWh for a single chamber and 0.165 kWh for both chambers at 75 °C for one hour, with single-chamber mode saving up to 40 % against dual-chamber operation. [1][4] No yearly total can be computed — the research gives no duty-cycle or electricity-rate data — and the desiccant costs nothing to own because it regenerates during drying. Unplug the dryer when it is not in use or before cleaning, and keep the ventilation openings clear. [12]

When it is a good buy

Creality US store lists the X4L at $119.00 (compare-at $159.00), with a 14-day return window and up to a 12-month warranty. [3]
Creality VIP Mall lists the US-plug unit at $167.01. [6]
The 3D Factory in Cyprus lists it at €149.00. [19]
MakerParts 3D lists it without a captured price, with 30-day returns and a $4.99 return-shipping fee. [18]

At the $119 US store price it is a reasonable step up from single- or two-spool dryers for multi-colour PLA, PETG, TPU and ABS work at 75 °C or less. [5] At or above the X4’s $159 sale price, the X4’s extra 10 °C and active moisture management usually justify the difference; if you print PA, PAHT or PC at 80-85 °C, the SpacePi X4 ($159 at the US store, compare-at $199) is the right machine.
