Polymaker HT-PLA-GF 1.8mm Blue PLA High Temperature Filament for 3D Printing, Heat Resistant to 302F, Easy Print, Annealing, Works with Most

HIGH THERMAL STABILITY - Withstands temperatures up to 302 degrees Fahrenheit, making it ideal for hot environments such as garages, car interiors or surfaces exposed to the sun. HT-PLA-GF resists warping or warping - perfect for garden tools, garages and vehicle parts. Hassle-free printing: HT-PLA-GF prints with ease similar to PLA and supports speeds up to 350mm/s. It provides smooth extrusion, conceals layering lines and offers excellent dimensional accuracy, making it a reliable choice for printing companies and high-throughput manufacturing processes. HT-PLA vs HT-PLA-GF - HT-PLA offers high heat resistance with the same strength as regular PLA, making it ideal for aesthetic or non-load-bearing prints. For increased rigidity, strength and flammability, HT-PLA-GF is the best choice for functional parts. SHIPPING AND READY TO STORE: Designed to maintain print shape and quality during long-haul shipping or longer storage. HT-PLA-GF resists deformation due to heat, making it ideal for printed parts that need to be stored, transported or distributed without structural loss. Excellent Surface Finish - Achieve a satin finish with minimal surface finish. HT-PLA-GF prints cleanly and consistently, making it ideal for parts where both functionality and appearance are important, such as garage stands, exterior casings or exposed prints. Coil Packaging & Feeding - Each spool is made of hard cardboard with reinforced edges for smooth feeding and minimal dust. Compatible with AMS, dry boxes and most reel holders; Easy to store, easy to load – optimized for efficiency in organized print setups. MADE FOR MANUFACTURERS AND ENGINEERS - Trusted by engineers, hobbyists and printing shops, HT-PLA-GF delivers reliable results across all production batches. Ideal for repeatable printing of strong parts such as workbench tools, fixtures, devices or machine-ready prototypes. Recommended tempered nozzle: HT-PLA-GF contains glass fibers and can wear out over time standard brass nozzles. Use a hardened or ruby tipped steel nozzle for optimal performance, consistent extrusion and to extend the life of Hotend components for extended work. Annealing for Performance - Unlocks increased heat output by annealing prints at 212°F for 30 minutes. Annealing improves heat deflection and dimensional stability, ideal for parts used in hot environments or repeated operating conditions. Enhanced Functionality: HT-PLA-GF is reinforced with fiber optic for increased rigidity and reliability. Ideal for tool holders, mechanical supports and functional casings where dimensional accuracy and heat resistance are critical for long-term performance.
