SUNLU High Speed PETG Filament 1.75mm 4KG Bundle - Fast, Tough Color

In this review of the SUNLU High Speed PETG Filament 1.75mm 4KG Bundle the bottom line is simple: this pack is for makers who need durable, impact-resistant parts and want the option to print much faster than typical PETG. The reviewer found the filament blends the ease of PLA with the toughness of ABS and supports high-speed workflows up to 600mm/s when tuned, making it a solid choice for functional prototypes and end-use parts where strength matters.

Key Features

• High speed printing: The filament melts and flows smoothly to enable print speeds from about 50mm/s up to 600mm/s when paired with the recommended nozzle temperatures, shortening project turnaround time.
• PLA and ABS benefits: PETG combines the easy handling of PLA with the toughness of ABS, so users get simpler printing plus stronger printed parts for practical uses.
• Enhanced toughness: The material offers improved durability over many filaments, making it suitable for parts that must withstand stress and repeated use.
• High impact strength: Prints resist bumps and drops better than brittle materials, which helps maintain part integrity in functional applications.
• Color variety: The 4kg bundle provides four 1kg spools in Blue, Green, Orange, and Yellow, useful for multi-color projects or prototyping iterations.
• Recommended settings guidance: The included temperature and speed ranges help users dial in printing profiles for different speed tiers to reduce trial and error.

Who It's For

The SUNLU High Speed PETG bundle is best for hobbyists, makers, and small workshops that need stronger printed parts and want to experiment with higher throughput. It works well for functional prototypes, jigs, mounting brackets, and any application where impact resistance and toughness are priorities.

Users who prioritize flawless color fidelity or a glossy showpiece finish may want to compare samples first, since feedback on matte finish and color quality is mixed. Also, those who need ultra-fine aesthetic prints with minimal stringing should be prepared to tune retraction and temperature settings for optimal results.

Pros & Cons

Pros

• Good balance of ease of use and strength, combining benefits of PLA and ABS for everyday parts.
• Supports a wide range of print speeds up to 600mm/s when tuned, improving throughput.
• High impact resistance yields durable parts that resist cracking and wear.
• Bundle of four 1kg spools provides useful color options for prototyping and multi-part projects.

Cons

• Some customers report mixed results with color quality and matte finish, so aesthetic results may vary.
• Adhesion and stringing behavior can require tuning on certain printers to avoid issues at speed.

Our Verdict

The SUNLU High Speed PETG 4kg bundle is a practical pick for makers who need robust, impact-resistant parts and want to experiment with faster print speeds. It offers strong value through four usable color spools and clear temperature guidance, but users should plan a short tuning session for adhesion and stringing when pushing higher speeds.

Frequently Asked Questions

What speeds and temperatures work best?
Use the tiered guidance: 50-100mm/s at 230-240C, 100-300mm/s at 240-255C, and 300-600mm/s at 255-270C, with a 70-80C bed.

Is this filament easy to print like PLA?
Yes, PETG behaves more like PLA to print while providing greater toughness similar to ABS, though it needs temperature and retraction tuning.

Will the colors match across spools?
Colors are useful for prototyping, but customer feedback shows some variability in matte finish and color quality, so test a sample for critical color work.
