Bambu Lab PPS-CF Filament — 1.75 mm, 0.75 kg, Black

PPS-CF sits at the very top of Bambu Lab’s engineering filament range. The base polymer — polyphenylene sulfide — is a semi-crystalline high-performance thermoplastic used in automotive under-bonnet components, chemical processing equipment and electrical hardware. Bambu Lab reinforces it with chopped carbon fibre for stiffness and dimensional stability, producing a filament that stays structurally useful at temperatures where PLA, PETG and even ASA have long since deformed.

This is a specialist material, not an everyday one. It suits engineers, workshops, research groups and small manufacturers printing functional end-use parts: sensor housings and brackets that live near an engine or heater, jigs and fixtures exposed to solvents, insulators and connector bodies that need inherent flame retardancy, and semiconductor or laboratory tooling that must not off-gas or swell. If your part needs to be tough and hot and chemically exposed, PPS-CF is the answer — and it is delivered in a single production colour, Black (76100).

Printer compatibility — read this first

PPS-CF needs both a very hot hotend and a heated, enclosed chamber. Bambu Lab lists it as compatible with the X1E and H2D only — machines with active chamber heating and a hotend rated past 300°C. It will not print successfully on a P1P, P1S, X1C, A1 or A1 mini. A hardened steel nozzle is mandatory: the carbon fibre will chew through a stainless or brass nozzle quickly. Use 0.4 mm, 0.6 mm or 0.8 mm hardened; the 0.2 mm nozzle is not compatible, and 0.6 mm is the sweet spot for flow and reliability.

Recommended print settings

• Nozzle temperature: 310–340°C (hardened steel required)
• Bed temperature: 100–120°C — smooth or textured PEI
• Chamber temperature: 60–90°C, actively heated
• Print speed: below 100 mm/s — slower is better for interlayer bonding
• Part cooling fan: 0–40% — keep it low so layers fuse properly
• Drying before use: 100–140°C for 8–12 hours in a blast drying oven (or 110–120°C for 10–12 hours on an X1 heatbed, which is less effective)
• Optional annealing: 180–220°C for 6–12 hours to maximise crystallinity, strength and heat resistance

Practical tips

Dry it properly, every time. PPS-CF absorbs very little moisture compared with nylon, but the carbon fibre content still traps water and a wet spool prints with poor surface finish and weak layers. A standard filament dryer topping out at 70°C will not do the job here — you need a blast drying oven at 100–140°C. Load the spool straight from the dryer into a sealed AMS or dry box with fresh desiccant and print it the same day.

Anneal for real-world heat performance. Straight off the printer, PPS-CF is only partly crystallised. If your part will actually see sustained high temperatures, anneal it at 180–220°C for 6–12 hours — this significantly lifts strength and heat resistance. Expect a small amount of shrinkage during annealing, so print a test part first and dial in your dimensions before committing to a final run. Keep the chamber at temperature and part cooling low throughout the print: PPS-CF is sensitive to warping, and a draught across a hot part is the fastest route to a delaminated corner.
