====== PPS - Polyphenylene Sulfide ======
PPS is the "first of the superplastics", featuring both incredible chemical resistance and high temperature tolerance. Although the cost is prohibitive, it remains cheaper and easier to print than the other polymers in class.

While this page is intended to cover PPS as well as PPS-CF, there has not yet been information gathered on unfilled PPS. __Your__ contributions in this area are welcome!
==== Advantages ====
  * Broad chemical resistance
  * High strength and modulus
  * CF-filled PPS is printable with common printers
==== Disadvantages ====
  * Requires high-temperature post-processing (annealing) for best performance
  * Cost, availability
  * Inconsistent behavior between vendors
==== Variants ====

Standard guidance on [[filaments:additives|additives]] applies.

==== Annealing ====

PPS responds well to high temperature annealing (TODO: expand on this with sources). 180C is a good starting point, but temperatures up to and beyond 204C yield only improvements to the final result. Research indicates that this trend continues up until (and slightly beyond) the melting temperature of the base material.

==== Baseline Printing Recommendations ====

These numbers are provided as a baseline, and **need** adjustment and calibration for your specific printer/filament/color combination.

==== Other notes ====

PPS-CF is known to have a large variety in behavior from vendor to vendor.
