Polymaker™ HT-PLA-GF White - 1.75mm 1kg

Polymaker HT‑PLA GF Filament

• Material Type: High Temp PLA reinforced with glass fiber

• Diameter: 1.75 mm (±0.02 mm tolerance)

• Weight: 1 kg spool

• Special Features:

  • Glass fiber reinforcement for extra stiffness and strength

  • Heat resistant up to 150 °C after annealing

  • Low warping and improved dimensional stability

  • Matte surface finish with reduced layer visibility

  • Neatly wound spool for consistent extrusion

Mechanical & Thermal Properties

• Heat Resistance: Up to 150 °C (post‑annealed)

• Strength: Higher rigidity compared to standard HT‑PLA

• Surface Finish: Matte, textured look due to glass fiber content

• Durability: Enhanced mechanical stability and reduced shrinkage

Printing Specifications

• Recommended Print Temp: 210 – 230 °C

• Bed Temp: 25 – 70 °C (heated bed recommended)

• Cooling Fan: 100% recommended for best results

• Nozzle Recommendation: Hardened steel or wear‑resistant nozzle (abrasive material)

• Compatibility: Works with most FDM/FFF printers capable of handling composite filaments

Practical Use Cases

• Best For:

  • Functional prototypes requiring strength and heat resistance

  • Mechanical parts with low deformation under stress

  • Engineering applications needing rigid, stable prints

• Not Ideal For:

  • Flexible or impact‑absorbing parts

  • Printers with soft brass nozzles (abrasion risk)

Considerations

• Requires annealing to achieve maximum heat resistance.

• Glass fiber content makes the filament abrasive — hardened nozzle strongly recommended.

• Slight shrinkage may occur during annealing — calibration advised.

Reasons to Choose Polymaker HT‑PLA GF

• Superior rigidity compared to standard HT‑PLA

• Excellent heat resistance after annealing

• Matte finish for professional‑looking parts

• Reliable spool quality with smooth extrusion
