[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 250°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.

[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]

  1. PEEK printing requires a fully enclosed, high-temperature 3D printer.

  2. Ensure adequate ventilation during printing due to high processing temperatures.

  3. Regular maintenance of high-temp components is recommended for consistent performance.

Experience the power of industrial-grade PEEK — engineered for professionals who demand maximum strength, precision, and performance.

PLA is the most commonly used 3D printing material, it is economically and begainner-friendly with rich colors.
PLA Meta is an upgraded version of PLA, with lower printing temperature, better toughness and softer colors.

PLA is a food-safe material, but the filament will be added with toner during the production process, and it may also be contaminated by the printing nozzle during the printing process, so we do not recommend you to use PLA to print tableware

The printing quality will be affected if the PLA is moistured. Please pay attention to moisture-proof of the filament, or use a drying box to dry the filament

To store PLA filament and PLA+ filament, it is recommended to keep them in a dry and cool place, away from direct sunlight and moisture.

Clean the nozzle, try turning the printing temperature up.

Check the distance between the nozzle and the hot bed, try to increase the printing temperature or the hot bed temperature

PLA and PLA+ filaments are recyclable.

PLA and PLA+ filaments can be used on most FDM 3D printers, as long as the printer's hotend temperature can reach the recommended temperature for the filament
