The useful question is not “Does this dryer list nylon?” It is “Can it follow the drying instructions for this exact spool?” PA6, PA12, filled blends and different manufacturers can need different conditions.
Start with the spool instructions
Find the manufacturer’s temperature, duration and any spool restrictions. Use those together. A lower temperature for an arbitrary extra period is not a verified substitute for the maker’s recipe. If instructions are missing, ask the filament manufacturer before buying a dryer for that material.
Where the SpacePi X4 fits
The SpacePi X4 is the higher-temperature option in our current shortlist. Creality declares up to 85°C and two independent chambers, so it is a candidate when your material’s instructions fit within that range. The separate zones are useful for drying a hotter material alongside a lower-temperature pair.
If the requirement exceeds 85°C, none of the models in this shortlist is a documented match. We would rather leave that choice open than call a machine suitable because its marketing mentions engineering materials.
Look past the material name in a listing
X4 and X4L are different models. So are the regular Space Pi and Space Pi Plus. Check the selected option in the retailer listing, the declared temperature ceiling and your local power specification. Do not choose using a photograph or family name alone.
Keep dry material dry while printing
After drying, plan the path from the spool to the printer. A sealed storage arrangement reduces exposure; it does not prove that a previously wet roll has been dried. Check whether your feed route bends flexible filament sharply or restricts spool movement.
See drying versus storage for that distinction. If your material fits below 70°C, the main comparison includes smaller options that may suit your routine with less equipment.
