Bambu Lab PPS-CF is a highly specialized technical filament made of polyphenylene sulfide (PPS) reinforced with carbon fibers. The combination of the PPS matrix and carbon fibers provides exceptional heat resistance, chemical stability, mechanical strength, and dimensional stability - the material is designed for the most demanding industrial and engineering applications.

Key features

PPS-CF ranks among the top engineering filaments. It offers a heat deflection temperature (HDT) of up to 264 °C at 0.45 MPa load and the ability to operate long-term at temperatures above 200 °C, significantly outperforming common materials such as PA-CF or PET-CF. Thanks to the UL-94 V-0 classification, it exhibits excellent self-extinguishing properties, making it ideal for electronics and automotive components.

The material is resistant to solvents, acids, alkalis, and salts - in terms of chemical stability, it ranks right behind PTFE (Teflon). Its extremely low moisture absorption (only 0.05%) ensures stable mechanical and thermal properties even in humid environments, unlike nylon materials. Reinforcement with carbon fibers increases stiffness (7160 MPa flexural modulus) and flexural strength (142 MPa) and ensures dimensional stability even for large parts.

Printing parameters

Who is the Bambu Lab PPS-CF 1.75, 0.75 kg filament suitable for

This material is intended for advanced users and industrial applications where standard filaments such as PLA, PETG, or ABS are insufficient. It is ideal for producing functional parts exposed to high temperatures, aggressive chemicals, and mechanical stress - such as components for automotive, aerospace, electrical engineering, chemical processes, motor housings, under-hood parts, and spare parts in petrochemistry and energy. Thanks to its self-extinguishing properties, it is suitable for safety components. Compared to CF filaments based on nylon or PET, it offers higher thermal and chemical resistance.

Printing tips

• The filament must be thoroughly dried before printing (100 - 140 °C, 8 - 12 h) - moisture significantly degrades print quality.
• Use only printers with an enclosed chamber and heated environment (Bambu Lab X1E, H2 Series).
• DO NOT USE 0.2 mm nozzles or stainless steel nozzles - carbon fibers damage them. Hardened steel is recommended.
• AMS and AMS lite are not compatible with this material - feed the filament directly from a sealed box with desiccant.
• Higher nozzle and chamber temperatures within the recommended range improve mechanical properties, especially along the Z axis.
• For better adhesion to the build plate, use a glue stick or Bambu liquid glue.
• When handling, cutting, and sanding, wear gloves - carbon fibers may cause skin irritation.
• For maximum mechanical properties, parts can be annealed after printing according to the manufacturer's TDS.
