Summary

A dual-spool heated filament dryer for 3D printing that takes two 1 kg spools, heats to 45–70 °C and can feed filament to the printer while it dries. Check the PTFE feed-tube routing before you buy: the supplied tube can slide inward, bind the spool and stop a print mid-job.

Strengths

  • An eight-hour dry removed severe stringing from a wet PLA spool, and a TPU spool printed cleanly afterwards.
  • Two 1 kg spools at once suits a multi-printer or multi-material shop.
  • Self-regulating PTC heaters spread more even heat than resistive-element budget dryers.
  • 12 presets and a 48-hour timer cover PLA, PETG, TPU, ABS, ASA, PC, PP, PA and CF variants.
  • Four feed outlets let the printer pull filament straight from the dryer.
  • Power-off memory keeps settings through outages.

Weaknesses

  • The PTFE feed tube can migrate inward and bind the spool mid-print; tape or hot glue is the fix.
  • Multiple owners report E4 heating-error shutdowns, and one unit died completely after about 10 months.
  • Below 15 °C (59 °F) ambient the dryer shows “EA” and refuses to heat.
  • The humidity readout is chamber air, not filament moisture, and floors at 13–15%.
  • Blower fan noise and reported fan failures; exact replacements are awkward to source.
  • The 70 °C ceiling leaves some nylons and PVA out of reach.

Drying performance and the humidity readout

GamingTrend’s before/after test dried a severely stringing PLA spool for about eight hours, then reran the same file with no settings changes — stringing was almost completely gone. A TPU spool dried for eight hours printed flawlessly. Syntaxglow measured about 120–140 W while drying PETG at 65 °C, peaking around 160–170 W at heat-up.

The display shows chamber air humidity, not filament moisture. Owners report the reading drops to about 15% and never goes lower, and it does not hold once heating stops. A wet spool can still need the full recommended drying time even when the display looks low. Treat the number as a trend, not a dryness certificate.

The PTFE tube problem

The supplied PTFE feed tube can slide inward over time during print-through use until it binds the spool and stops filament feed. Multiple sources report this, and it is a design flaw rather than user error. Tape or hot glue on the tube fixes it. If you print from the dryer, secure the routing before you start a long job.

E4 errors, cold lockout and fan noise

Creality’s support documentation defines E4 as a heating fault: the shield opens or the thermistor heats poorly. Owners report E4 shutdowns from leaving the lid open, from overheating with two full spools of ABS or ASA at 65 °C, from cold ambient, and from thermistor or mainboard faults. One owner reported E4 followed by total unit death — no screen, no fan — after about 10 months of light use. Creality has replaced circuit boards and motherboards under warranty for E4 failures.

In ambient temperatures below 15 °C (59 °F), the dryer displays “EA” and refuses to heat; the firmware reads a sub-15 °C thermistor value as a sensor fault and locks out heating. Owners in unheated workshops and garages call this a significant inconvenience. If your shop runs cold in winter, this dryer will sit idle.

Blower fan noise is a recurring complaint, and owners report fan failures after weeks or months. One owner replaced a failed sleeve-bearing blower, but exact replacements are awkward to source. Creality’s wiki has a fan replacement guide. The front screen assembly is glued in, which makes any service harder.

Is it worth it?

Creality’s own store lists the dryer at $89 (2026-10-07); it was sold out at research time. 3D Printed Decor listed it at $99.99 in January 2025, and Syntaxglow reported around $80 in February 2025. At $89 it is a fair buy for two-spool drying, provided you secure the PTFE routing and watch for E4 errors during the return window. Above $100 the case weakens: the Sunlu S4 four-spool dryer is $129.99, and four-spool capacity starts to make sense for multi-material shops.

Running costs are modest. Electricity is the only recurring one, at about 120–160 W while heating. Desiccant replacement is optional. There is no consumable lock-in.

Which model this is

This page covers the Creality Space Pi Filament Dryer Plus, the dual-spool heated dryer with internal designation AMUS-HYZ-3D-AC-DryerBox-Pro and US item number 4005010074. Creality’s US store now titles it “Space Pi Filament Dryer V2 Plus”, while CrealityCloud and most marketplace listings still say “Plus” — the same dual-spool hardware under a newer name. The Amazon listing is ASIN B0CY1S7MMK. Do not confuse it with the single-spool Space Pi, the Space Pi V2, or the four-spool X4 and X4L.
