3D printer filament POLYMAKER HT-PLA-GF 1.75 mm 1 kg Green

POLYMAKER HT-PLA-GF 1.75 mm in Green is a glass-fiber reinforced high-temperature PLA filament supplied on a 1 kg spool for FDM/FFF 3D printers that accept 1.75 mm filament. This material combines PLA's ease of printing with enhanced stiffness and improved heat resistance thanks to glass-fiber reinforcement, making it suitable for prototyping and functional parts where greater dimensional stability and rigidity are required. The filament is intended for users seeking a balance between printability and mechanical performance in everyday engineering and design applications.

Advantages

HT-PLA-GF delivers higher tensile stiffness and increased resistance to deformation at elevated temperatures compared with standard PLA while maintaining relatively simple print settings. The glass-fiber content improves layer-to-layer rigidity and reduces part warpage, supporting accurate dimensional results for moderate-load components. The filament's consistent diameter and spool packaging provide steady filament feed and predictable extrusion behavior on compatible FDM/FFF machines.

Suitable for

• Functional prototypes requiring improved stiffness and thermal stability
• Fixtures, jigs and small mechanical parts with moderate loads
• Scale models and parts that require reduced warping and accurate dimensions
• Applications where easier printing than composite nylons is preferred

How to use

Load the 1.75 mm spool into a compatible FDM/FFF printer and configure print settings according to the printer manufacturer's recommendations for PLA-based composites. Typical nozzle temperatures are higher than standard PLA—refer to the filament manufacturer's suggested temperature range if available—and a hardened steel or wear-resistant nozzle is recommended due to glass-fiber content. Use a stable build surface and appropriate bed adhesion (heated bed, glue stick, or PEI sheet) to reduce first-layer issues. Monitor the first layers and adjust retraction and cooling settings to minimize stringing and ensure good interlayer bonding.

Usage recommendations

For best results, use a hardened nozzle and moderate printing speeds. A heated bed set to a suitable temperature and secure part adhesion help maintain dimensional accuracy. Avoid overly aggressive cooling on the first layers, and consider post-processing methods such as light sanding or sealing if a smoother surface finish is required.
