Warning | Read before you buy:

PEEK filament is extremely difficult to print and intended for experienced users only. Please ensure you have prior experience with this material.
An industrial-grade 3D printer with a high-temperature hotend, heated chamber, and controlled environment is required.
Consumer-grade printers are not suitable and attempting to use them may cause equipment damage.
Proceed only after fully understanding the material’s requirements.

[High Performance Engineering Material]
SUNLU PEEK (Polyether Ether Ketone) filament stands at the top of the plastics pyramid, offering outstanding strength, thermal stability, and chemical resistance. Capable of continuous operation at 240°C and short-term exposure above 300°C, it’s ideal for industrial applications where other materials fail.

[Exceptional Mechanical Strength]
With a tensile strength of 100 MPa and flexural strength of 163 MPa, SUNLU PEEK delivers remarkable rigidity and toughness. It maintains stability under load, making it suitable for precision parts and heavy-duty mechanical components.

[Self-Lubricating, Low-Friction Performance]
SUNLU PEEK naturally reduces friction and wear, enabling smoother operation and a longer service life for moving parts, such as gears, bearings, and sliders—often without the need for additional lubrication. This low-friction advantage enhances durability, improves efficiency, and reduces maintenance for high-demand mechanical applications.

[Superior Thermal & Chemical Resistance]
Featuring a glass transition temperature of 143°C and a heat deflection temperature of 176°C, PEEK excels in high-temperature environments. Its exceptional chemical resistance ensures durability against acids, bases, and solvents — ideal for aerospace, automotive, and electronic parts.

[Self-Lubricating & Flame Retardant]
PEEK’s low friction coefficient minimizes wear and frictional heat, extending component lifespan. It also carries a V0 flame-retardant rating, providing additional safety in high-heat, high-stress environments.

[Ideal Applications]

Aerospace and automotive components
Functional mechanical fixtures and jigs
Bearings, bushings, and friction parts
Medical and orthotic devices
Food-contact and chemical-resistant containers

[Optimized Printing Settings]

Nozzle Temperature: 390–420°C (high-temp nozzle required)
Chamber Temperature: 80–90°C (enclosed printer recommended)
Printing Speed: 30–60 mm/s
Bed Adhesion: Apply high-viscosity curing adhesive
Maintenance: Replace nozzle periodically to avoid carbonization and clogging

[Important Notes]

PEEK printing requires a fully enclosed, high-temperature 3D printer.
Ensure adequate ventilation during printing due to high processing temperatures.
Regular maintenance of high-temp components is recommended for consistent performance.
