SUNLU PETG High-Speed Matte Filament 1.75 mm Grey 1 kg

Speed and strength rarely go hand in hand with PETG, but this matte grey filament from SUNLU breaks that rule. The high-speed formulation lets you push print speeds from 50 to 300 mm/s without sacrificing the toughness, low warping, and excellent layer adhesion that PETG is known for. The matte finish hides layer lines and gives parts a premium, non-reflective look, making it ideal for both functional prototypes and visual models.

Highlights

• High-speed formulation: print at 50–300 mm/s
• Matte grey surface hides layer lines
• Low warping and excellent layer adhesion
• Bubble-free, vacuum-sealed with desiccant
• Consistent 1.75 mm diameter (±0.02 mm)
• Compatible with most FDM 3D printers

In daily use

This PETG filament is a reliable workhorse for everyday printing. The matte finish gives printed parts a premium, non-reflective look, while the high-speed formulation lets you cut print times without sacrificing quality. With a recommended nozzle temperature of 220–250 °C and a bed at 70–80 °C, it adheres firmly and releases cleanly when the build plate cools. The spool is neatly wound to avoid tangles, and the low moisture absorption keeps prints consistent even in less-than-ideal storage conditions.
