Damp filament strings and pops, and a dryer is cheaper than a failed print · review

Creality Space Pi X4, four spools, two 200 W chambers review

The dearest dryer here, holding four 1 kg or two 2 kg spools in two independently heated 200 W chambers up to 85 °C, with a silicone seal to keep filament dry between prints.

By Jean-Benoit Buisson

The bottom line Strong on capacity and on temperature guidance by material, with a sealed chamber for storage. It does not say whether filament can feed a printer from inside, which the cheaper SUNLU here states.

The Space Pi X4 listing, bullet by bullet

Five bullets: storage for four standard 1 kg spools or two large 2 kg spools, compatible with 1.75 and 2.85 mm filament; two independent 200 W heating chambers up to 85 °C, described as removing moisture 30 % faster than single-chamber dryers; a dryer that also stores, keeping humidity low during print pauses in a silicone-sealed chamber with a lit window; a touch interface with drying scenes, 50–60 °C for PLA, PETG and TPU and 80–85 °C for ABS, PET, PC, ASA, PA and PAHT; and a longer filament life with less waste.

Temperature guidance by material

Two bands, nine materials. Few dryer listings publish which temperature suits which filament. This one does, and the page reports the bands as the maker’s guidance, with the filament maker’s own figure deciding for a given spool.

Built for storage

The silicone seal and the lit window describe a cabinet as much as a dryer. Spools can stay inside between jobs and be checked without breaking the seal.

The feed-through question

Unlike the SUNLU reviewed on this site, the listing does not mention printing from the box. For an owner who wants filament dried during a long print, that is the point to confirm before buying.

Availability

At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 199 € to 201 €.

The American and British Amazon stores returned no entry, so the buy button there opens a search rather than a missing page.

Where it earns its place, and where it falls short

Strengths

Accepts 2 kg spools as well as 1 kg, which the cheaper SUNLU reviewed beside it does not state
Published temperature bands by material: 50–60 °C for PLA, PETG and TPU; 80–85 °C for ABS, PET, PC, ASA, PA and PAHT
A silicone-sealed chamber and a lit window for checking spools without opening it

Compromises

No feed-through described, so printing directly from the dryer is not confirmed
No timer and no humidity display stated
The 30 % faster drying claim has no stated basis beyond comparison with single-chamber dryers

Questions makers ask before buying

What temperatures does it suggest by material?

The fourth bullet gives 50–60 °C for PLA, PETG and TPU and 80–85 °C for ABS, PET, PC, ASA, PA and PAHT. The filament maker’s own drying temperature takes precedence for a specific spool.

Can it hold 2 kg spools?

Yes, two of them, according to the first bullet, or four standard 1 kg spools.
