PETG/GF15 Filament 1.75mm – Black | 1kg
Kelvra PET‑G Glass Fibre (PETG‑GF) is a keenly reinforced 15%GF PET‑G filament developed for applications that demand greater strength, rigidity, and thermal stability than standard PETG can provide—without stepping into over‑engineered territory.
The incorporation of glass fibres significantly increases the strength and rigidity of the material compared to pure PETG, delivering notably improved tensile heat stability. As a result, PETG‑GF offers good thermal stability and can maintain consistent mechanical performance at higher temperatures, making it well suited to 3D printing in elevated‑temperature environments up to 78℃
Alongside its enhanced stiffness, PETG‑GF retains the chemical resistance, durability, and layer adhesion PET‑G is known for, ensuring parts remain reliable in real‑world industrial conditions. The reinforcement also helps reduce flex and deformation during printing, supporting clean geometry and dependable dimensional control, particularly on larger or load‑bearing parts.
Reinforced Where It Matters
This is not reinforcement for its own sake. Kelvra PETG‑GF is deliberately specified to provide practical gains in rigidity and heat performance, without unnecessary cost or processing complexity. It’s the considered choice when standard PETG starts to soften under load or temperature, but full engineering polymers would be overkill.
Printed parts feature a technical, low‑sheen surface finish that looks purposeful straight off the printer—no cosmetic rescue required.
