Kingroon High Speed PLA Filament 1.75mm Gray - Fast, Tangle-Free

In this review of the Kingroon High Speed PLA filament, the bottom line is simple: it is aimed at makers and professionals who need reliable, fast printing without sacrificing dimensional accuracy. Our review finds the filament excels when speed matters most, offering smooth flow at high feed rates and consistent diameter that keeps parts accurate. For anyone printing functional prototypes or multi-part assemblies, the combination of up to 600mm/s capability and tight tolerances makes this spool a practical choice.

Key Features

• High speed printing: The filament melts and flows rapidly to support printing speeds from 30 to 600mm/s, which shortens cycle time for fast iterations and large prints.
• Tangle free winding: Each full 1kg reel is wound with good roundness and tight tolerance so it feeds smoothly without overlaps or tangles during long prints.
• Dimensional accuracy: The 1.75mm diameter maintains tight tolerances (0.02-0.03mm reported range), which helps keep layer consistency and part fit across assemblies.
• Enhanced strength: Formulated for a higher flexural modulus and elongation at break, this PLA resists brittleness for more durable functional parts.
• Wide compatibility: Works with most common FDM printers and high speed machines, including a variety of Bambu Lab, Creality, Prusa, and other platforms.
• Recommended settings: Best results with a nozzle at 200-230C and a bed at 50-60C, allowing straightforward setup for typical PLA workflows.

Who It's For

This filament is best suited for hobbyists, rapid prototypers, and small workshops that want to reduce print time while retaining consistent dimensional performance. Users running high speed machines or tuning for faster travel will appreciate the improved fluidity and stability at elevated extrusion rates.

Users who need specialty materials like flexible TPU, engineering-grade nylons, or high-temperature resins should look elsewhere, since this product is a PLA formulation focused on speed, printability, and general-purpose strength rather than extreme flexibility or heat resistance.

Pros & Cons

Pros

• Prints cleanly at high speeds with smooth extrusion and minimal stringing, improving throughput.
• Consistent diameter and roundness reduce clogging and improve part dimensional accuracy.
• Good toughness for PLA makes printed parts less brittle and more functional for end-use prototypes.

Cons

• Adhesion reports are mixed across users, so bed preparation may require tuning for certain machines and surfaces.
• As a PLA, it is not suitable for applications needing high heat resistance or large chemical durability.

Specifications

Our Verdict

The Kingroon High Speed PLA filament is a smart choice for users who prioritize faster print times and consistent diameter control. It offers excellent value for prototyping and functional prints that need improved toughness and minimal stringing, provided the user is willing to tune bed adhesion on their specific printer. For general-purpose PLA where speed and reliability matter, it represents a practical balance of performance and cost.

Frequently Asked Questions

Will this filament work with my high speed printer?
Yes, it is formulated for high fluidity and lists compatibility with many high speed and common FDM models, but tuning temperatures and retraction for your machine is recommended.

What printing settings are recommended?
Use a nozzle temperature of 200-230 C, a bed temperature of 50-60 C, and a print speed in the 30-600 mm/s range depending on your printer and desired quality.

Does it tangle or clog often?
The spool is wound to reduce tangles and is described as feeding smoothly; customers report low clogging when using correct temperatures and a well-maintained extruder.
