Qidi PPS-CF Filament Review: Unleashing High-Performance 3D Printing

MATERIALS

4/12/20253 min read

In the pursuit of stronger, more heat-resistant, and chemically resilient 3D printed parts, materials like PPS-CF (Polyphenylene Sulfide reinforced with Carbon Fiber) are gaining prominence. Qidi, a well-known name in the 3D printing industry, offers its own PPS-CF filament, and this review will delve into its key characteristics and performance.

What is PPS-CF? A High-Performance Blend

To appreciate the capabilities of Qidi's PPS-CF, it's essential to understand its composition:

  • Polyphenylene Sulfide (PPS): This is a high-performance engineering thermoplastic known for its:

    • Exceptional chemical resistance

    • High thermal stability

    • Inherent flame retardancy

    • Dimensional stability

  • Carbon Fiber (CF): The addition of carbon fibers enhances the mechanical properties of PPS, providing:

    • Increased stiffness and rigidity

    • Improved strength

    • Reduced creep (deformation under load over time)

The combination of PPS and carbon fiber results in a filament that can withstand demanding conditions, making it a potential replacement for certain metal components.

Key Properties of Qidi PPS-CF

Qidi's PPS-CF filament is designed to deliver a range of impressive properties:

  • Ultra-High Heat Resistance: A standout feature is its high heat deflection temperature (HDT), allowing printed parts to retain their shape and strength at elevated temperatures. This is crucial for applications where parts are exposed to heat.

  • Excellent Chemical Resistance: PPS-CF exhibits resistance to a wide range of chemicals, including solvents, acids, and bases. This makes it suitable for use in harsh environments.

  • Flame Retardancy: The material's inherent flame retardancy adds a layer of safety, making it a viable option for applications where fire resistance is essential.

  • Superior Mechanical Properties: The carbon fiber reinforcement significantly enhances the stiffness, flexural strength, and tensile strength of the PPS polymer, resulting in robust and durable parts.

  • Low Moisture Absorption: Compared to other high-performance materials like Nylon, PPS-CF tends to absorb less moisture, which simplifies printing and ensures dimensional stability.

  • Dimensional Stability: PPS-CF is known for its low shrinkage and warping tendency, allowing for the printing of precise and accurate parts, even in larger sizes.

Printing Considerations

Printing with PPS-CF requires a 3D printer capable of reaching high temperatures and possessing specific features:

  • High-Temperature Nozzle: A nozzle capable of reaching temperatures of 300°C or higher is essential.

  • Heated Bed: A heated bed is necessary to ensure proper bed adhesion and prevent warping.

  • Enclosed Build Chamber: An enclosed build chamber is highly recommended to maintain a stable temperature and minimize warping, especially with larger parts.

  • Wear-Resistant Nozzle: Carbon fiber is abrasive, so a hardened steel or other wear-resistant nozzle is crucial to prevent nozzle wear.

  • Proper Ventilation: Ensure good ventilation when printing with PPS-CF, as it may release fumes.

Applications of Qidi PPS-CF

The unique properties of Qidi's PPS-CF filament make it suitable for a variety of demanding applications:

  • Automotive: Components for engine bays, fuel systems, and other high-temperature environments.

  • Aerospace: Lightweight and strong structural parts.

  • Chemical Processing: Parts that come into contact with corrosive chemicals.

  • Electronics: Insulators and housings that require heat and flame resistance.

  • Industrial Equipment: Gears, bearings, and other wear-resistant parts.

The Qidi PPS-CF Experience: A Review

To provide a comprehensive review, consider these aspects:

  • Printability: How easy is it to extrude? Does it flow well? Is there warping?

  • Surface Finish: What is the texture and appearance of the printed part?

  • Strength and Durability: How well does the printed part withstand stress and impact?

  • Dimensional Accuracy: How closely does the printed part match the intended dimensions?

  • Consistency: Is the filament diameter consistent? Does it print reliably?

  • Value for Money: How does the price compare to other high-performance filaments?

If you're seeking a high-performance filament that can handle demanding applications, Qidi's PPS-CF is definitely worth considering.
