QIDI PPS-CF 3D Printer Filament
PPS-CF is a composite material made from carbon fiber-reinforced polyphenylene sulfide (PPS). The combination of PPS resin with carbon fiber imparts excellent properties to PPS-CF, including outstanding solvent resistance, corrosion resistance, heat resistance, and flame retardancy. Additionally, higher printing temperatures enhance the strength, rigidity, and dimensional stability of PPS-CF. When paired with the QIDI Plus4, it becomes a specialty engineering plastic capable of meeting the demands of unique and challenging applications.
Heat Resistance Up to 264℃
PPS-CF features a heat deflection temperature of up to 264°C at 0.45 MPa and can maintain continuous operation at temperatures above 200°C. Its superior heat resistance ensures excellent creep resistance, making PPS-CF an ideal choice for challenging industrial environments and high-temperature applications.
Excellent Flame-resistant
PPS-CF is rated UL-94 V-0 for flame retardancy, ensuring exceptional safety and reliability in key applications like electronics and automotive parts. Its outstanding durability provides lasting performance and confidence, even in the most challenging conditions.
Top-tier Mechanical Properties
PPS-CF integrates the rigidity of PPS polymers with the reinforcing power of carbon fibers, delivering superior stiffness, flexural strength, and tensile strength. Its outstanding dimensional stability and resistance to warping ensure that large-scale prints retain precision and remain distortion-free throughout production, making it perfect for high-precision applications.

Solvent and Chemical Resistance
PPS-CF exhibits excellent solvent and chemical resistance. At temperatures below 200°C, it is virtually insoluble in any solvent and demonstrates outstanding resistance to acids, alkalis, and salts under normal conditions. This makes PPS-CF an ideal choice for demanding environments where high chemical stability is essential.
Ultra-Low Water Absorption
PPS-CF has an extremely low moisture absorption rate of just 0.05%, ensuring that its mechanical and thermal properties remain stable even in humid conditions. This makes it an optimal choice for applications that demand high moisture resistance.

Printing Tips
1. Using higher values within these ranges can enhance the mechanical properties of the printed parts, especially in the Z-direction.
2. Higher temperatures within the drying range yield better results, but do not exceed 160°C to avoid damaging the spool.
3. To prevent the filament from absorbing moisture, use an airtight storage container with desiccant during printing.
