Product Details
- Glass Fiber Reinforced PETG: Glass fiber reinforcement improves stiffness, dimensional stability and resistance to deformation under continuous load, making the filament suitable for brackets, fixtures, housings, tools and functional prototypes.
- Non-Conductive Material Performance: The PETG and glass fiber formulation provides non-conductive material properties for printed housings, covers, mounting parts and other applications where electrical conductivity is not desired.
- Durable Matte Finish: Added glass fibers create a refined low-gloss surface that helps reduce the appearance of layer lines while maintaining the toughness and layer adhesion needed for frequently handled functional parts.
- Stable Printing with Low Warpage: Controlled 1.75mm filament diameter supports consistent feeding and smooth extrusion. The low-shrinkage PETG base helps reduce warping and improves dimensional accuracy on larger or detailed models.
- Compatibility and Printing Tips: Works with most 1.75mm FDM 3D printers. Start with a 240–270°C nozzle and 65–75°C bed. Use a 0.4mm or larger hardened steel nozzle because glass fiber-filled filament is abrasive. Adjust settings by printer.

Printing IEMAI PETG-GF
IEMAI PETG-GF in Matte White is PETG filled with chopped glass fiber, and this listing is a 1kg spool. The fibers make parts stiffer and more dimensionally stable than plain PETG, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). The ranges below are for PETG-GF, which usually prints a little hotter than plain PETG. PETG-GF is best suited to stiff, stable functional parts that handle knocks better than carbon fiber grades. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.
Ranges checked against Elegoo data. Heat resistance is the heat deflection temperature (HDT). Read our glass fiber filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.
Nozzle Compatibility
Glass fiber is abrasive and wears brass (and stainless) nozzles out of round, sometimes within a single spool. Use hardened steel or another wear resistant nozzle such as ruby or tungsten carbide. With hardened steel, start about 5 to 10°C hotter than you would with brass.
