Kingroon High Speed PETG Filament 1.75mm - Rapid Printing Bundle

In this review of the Kingroon High Speed PETG Bundle, the bottom line is simple: this filament is aimed at users who want reliable, fast PETG prints without frequent jams. The reviewer found the spool well-wound and consistently dimensioned, which combines with enhanced melt flow to allow very high print speeds while maintaining good surface finish. For makers producing functional parts and prototypes who value toughness and speed, this PETG delivers a compelling balance of strength and feed reliability.

Key Features

• 30-600mm/s Printing Speed: Enhanced fluidity lets the filament melt and flow quickly so users can test high-speed toolpaths up to 600mm/s without drastic loss of quality.
• Tangle Free & No Plugging: The full 1kg spool is wound with tight, even layers to minimize overlap and reduce the chance of feed jams during long prints.
• Wide Compatibility: Works with common 1.75mm FDM printers including many high-speed models, making it easy to switch filaments across machines.
• Dimensional Accuracy & Consistency: Close diameter tolerance ensures steady extrusion and predictable flow for detailed prints and repeatable results.
• Enhanced Strength & Toughness: High flexural modulus and elongation reduce susceptibility to brittle failure, useful for functional or mechanical parts.

Who It's For

The Kingroon RAPID PETG is best for hobbyists, small shops, and makers who print functional parts and prototypes and want to push higher extrusion speeds while retaining reliable feeding. Its toughness and consistent diameter make it practical for brackets, housings, and other utilitarian items that may see stress.

Those who should look elsewhere include absolute beginners who prefer PLA for easy bed adhesion and lower printing temperatures, or users requiring specialty materials such as flexible TPU or engineering-grade nylons; this filament is a PETG focused on speed and toughness rather than exotic properties.

Pros & Cons

Pros

• Excellent high-speed performance with smooth melt and flow for faster print cycles.
• Well-wound 1kg spools with tight diameter tolerance reduce tangles and feeding issues.
• Good mechanical toughness and flexibility for functional parts.
• Broad printer compatibility makes it a practical choice for many FDM setups.

Cons

• Adhesion can be mixed depending on bed surface and setup, so some calibration may be needed.
• As PETG, prints typically require higher nozzle and bed temperatures compared with PLA, which may be inconvenient for some users.

Specifications

Our Verdict

The Kingroon High Speed PETG Bundle is a solid choice for users who need fast, durable PETG with consistent feeding and minimal tangles. When paired with an appropriately tuned hot end and bed, it delivers good surface quality and mechanical resilience at higher print speeds, making it good value for makers and small shops focused on functional parts.

Frequently Asked Questions

Will this filament work with my 1.75mm printer?
Yes, it is designed for standard 1.75mm FDM printers and lists broad compatibility with both consumer and high-speed models.

What temperatures give best results?
Recommended settings are 230-260C for the nozzle and 70-90C for the bed; tweak within that range for optimal adhesion and finish.

Is stringing a major issue?
Most users report smoothness and low stringing, but stringing can vary by slicer retraction settings and hot end temperature, so some tuning may be needed.
