PPS filament

Polyphenylene sulfide. Chemically resistant to almost everything and naturally tan, so it is rarely pigmented.

• Enclosure recommended — Shrinks enough while cooling that draughts cause warping and split layers. An enclosure, or simply a still room, makes the difference.
• Keep dry — Absorbs moisture from the air, which prints as stringing, popping and weak layers. Filament that has sat out usually needs drying before use.
