SUNLU S1 Plus review

The most-rated dryer here at under $40: one spool up to 210 mm across and 85 mm wide, with a 6-hour default and printing during drying.

Why dry filament

Damp filament strings and pops. A dryer costs less than a failed print.

Capacity

A printed limit of Φ210 × 85 mm lets you check a cardboard spool first.

Limits

Check your filament’s drying temperature against the machine. For engineering filaments, see the Space Pi X4.
