Description & Opinion

Numakers PETG‑HS Filament (1.75 mm / 3 kg)

I recently tried Numakers PETG‑HS and was really impressed. It’s made from 100% virgin polymer, with no fillers, yet engineered for high-speed printing using standard PETG settings—so you get faster prints without any hassle.

👍 Key Highlights

Fast, Reliable Printing
Optimized for high flow, PETG‑HS prints quickly—comparable to “high flow” PETGs—while maintaining excellent layer adhesion and low warping. Perfect for functional parts that need strength and heat resistance.

Strong & Durable
Known for its toughness, chemical/UV resistance, and ability to perform in temperatures up to 75 °C. Ideal for outdoor uses, mechanical pieces, or parts that need to take a beating.

Smooth Surface Finish
Prints come out glossy and polished, with low odor and easy-to-sand qualities. Available in bold colors and a high-transparency clear option.

User Experience
PETG‑HS prints well on both heated and unheated beds, though a bed temperature of 80–90 °C is recommended for best results. Works smoothly with standard PEI, glass, tape, glue-stick surfaces. Part cooling fan at 20–50% improves results, and while it can ooze or string slightly, tuning retraction settings handles that easily.

⚠️ Things to Watch

Some experienced users note slight stringing or oozing—common with all PETGs. And strong bed adhesion can sometimes make part removal a little tough—but I'd rather have secure first-layer adhesion than risk lifting.

Bottom Line

If you want a fast‑printing, strong, and glossy PETG filament that doesn’t compromise quality, Numakers PETG‑HS is a top choice. It’s perfect for makers who need durability and speed without needing specialized printers or exotic settings. A reliable workhorse for everyday printing.
