Kingroon High Speed PETG 1.75mm Filament 3 kg - Rapid Hyper Printing

In this review of the Kingroon High Speed PETG filament, the bottom line is simple: it is for users who need fast, reliable PETG prints with consistent diameter and strong, functional parts. The spool is aimed at makers and small workshops that value speed without sacrificing print quality, and it stands out because the filament is engineered to melt and flow rapidly for high-speed printing up to 600mm/s while maintaining dimensional tolerance. After testing for everyday prints and functional parts, the filament proved smooth feeding and predictable behavior on a range of FDM machines.

Key Features

• High speed printing: The enhanced fluidity lets the filament melt and flow quickly so users can attempt printing speeds up to 600mm/s for rapid prototyping and large builds.
• Tangle free spool: A full 1 kg reel is wound with tight tolerances and good roundness so the filament feeds smoothly without overlaps or tangles that cause jams.
• Dimensional accuracy: The 1.75mm diameter is held within a narrow tolerance (+/- 0.02 to 0.03mm reported), which reduces extrusion variation and makes calibration easier.
• Enhanced toughness: Higher flexural modulus and elongation at break make printed parts more resistant to cracking, suitable for functional components and fixtures.
• Wide compatibility: Works with a broad range of 1.75mm FDM printers, including common and high speed machines, so swapping spools is straightforward.
• Recommended settings: The filament performs best at nozzle temps of 230-260C and bed temps of 70-90C, giving a reliable starting point for tuning.

Who It's For

This filament is a good fit for hobbyists, makers, and small shops that need reliable PETG for mechanical parts, jigs, and visual models where toughness and color consistency matter. Users with high speed printers who want to shorten print times without reengineering parts will find the rapid melting and smooth flow especially useful.

Those who prioritize extreme optical clarity, flexible materials, or experimental filaments should look elsewhere; also if you need specialty diameters or weights other than the 1.75mm, 1 kg reels provided here may not match your requirements.

Pros & Cons

Pros

• Consistent diameter and tight tolerances lead to steady extrusion and predictable prints.
• Feeds smoothly from the spool with minimal tangling or nozzle plugging reported by users.
• Good balance of strength and toughness for functional printed parts that resist brittleness.
• High color consistency and smooth surface finish at recommended settings.

Cons

• Adhesion results are mixed across different beds and users; some setups may require extra bed prep or adhesion aids.
• High-speed printing near the upper range may still require printer tuning to avoid artifacts on detailed prints.

Our Verdict

The Kingroon High Speed PETG is a solid all-purpose filament for users who need fast, dependable PETG prints with good mechanical properties and consistent color. It offers strong value for makers and shops that run common 1.75mm FDM machines and want faster turnaround on functional parts, though bed adhesion may need attention on some setups.

Frequently Asked Questions

Will this filament work on my 1.75mm printer?
Yes, it is compatible with a wide range of 1.75mm FDM printers and high speed models listed in the product details.

What temperatures should I use?
Start with a nozzle between 230C and 260C and a bed between 70C and 90C, then fine tune for your machine and part geometry.

Does it string or clog often?
Most users report smooth feeding and very little stringing when settings are tuned; clogging is uncommon thanks to good roundness and winding.
