PPS-CF is carbon-fibre-filled polyphenylene sulfide. A maker sells it for expanded-foam mould tooling and railway parts, and makers say it resists solvents, acids and alkalis. It is semicrystalline, so it carries light load well above its glass transition: its HDT at 0.45 MPa is 251 °C. On the H2C it needs a hardened nozzle and drying at 100–140 °C, 2–12 h, and some products ask for more chamber heat than the printer reaches.
Partly documented Notched Charpy impact and price rest on 2 products each and tensile strength (Z) on 3 products. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar.

Among the materials
Against PPS-GF, PPS-CF is 76 % stiffer, 53 % more expensive and 36 % stronger flat. Against PPA-CF, PPS-CF is 19 % weaker flat, and its HDT at 0.45 MPa is 31 °C higher. Among the materials, PPS-CF has a high tensile modulus (XY), tensile strength (XY), HDT at 0.45 MPa, density and price, and a low elongation at break (XY) and notched Charpy impact: each is in the top or bottom quarter of the materials that publish it. Its tensile strength (Z) sits in the middle half.
Against its alternatives, PPS-CF has the highest HDT at 0.45 MPa and the lowest notched Charpy impact

Mechanical properties
Printed flat (XY), PPS-CF typically reaches a tensile strength of 87 MPa at a modulus of 8 GPa, and breaks at 2.2 % elongation. In bending, its flexural strength is typically 125 MPa at a flexural modulus of 6 GPa.
PPS-CF's products spread most in elongation at break: the middle half runs 1.4–4 %

Thermal properties
PPS-CF's HDT is typically 251 °C under 0.45 MPa and 132–235 °C under 1.8 MPa, against a glass transition of 92–100 °C. Semicrystalline, it carries light load well above its glass transition. As published, Vicat softening is typically 268 °C and melting typically 280 °C.

After printing
Two products publish values measured after annealing, at 125 °C for 16 h.
the suggested annealing temperature of models printed with Bambu PPS-CF is 180 to 220 °C, and the time is 6 to 12 hours.

Printing advice
If higher chamber temperature and nozzle temperature were used (i.g., 90 °C and 335 °C), higher mechanical properties would be obtained, especially the Z-direction's.

More from makers: moisture sensitivity, warping and shrinkage, odour and emissions and supports and removal
Moisture sensitivity
PPS-CF filament should always be fed to the printer in a dry container and stored in a dry cabinet to minimize absorbed moisture.
Essentium PPS-CF, data sheet, p. 2
Warping and shrinkage
Fiberon™ PPS-CF10 is a carbon fiber reinforced PPS (Polyphenylene sulfide) filament, with minimal warping during printing and no need for a heated chamber.

Odour and emissions

Supports and removal
Otherwise, the support structure can be bonded to the model, which will make the support hard to remove.
