High Speed PETG Filament 1.75mm 4KG Bundle - 4 Colors Pack

In this review of the SUNLU High Speed PETG Filament 1.75mm 4KG Bundle the bottom line is simple: this kit is aimed at makers and small shops that need reliable, tough parts and want the option to print very quickly. The review found the standout reason to buy is the filament's enhanced fluidity and broad recommended temperature range that make high-speed printing up to 600mm/s possible while retaining good layer bonding and impact resistance. For users who value durability and fast turnaround, this is a practical, value-oriented pack.

Key Features

• High speed printing: The filament melts and flows smoothly for printing at speeds from 50mm/s up to 600mm/s, reducing print time for large batches and prototypes.
• PLA and ABS benefits: PETG combines PLA-like ease of use with ABS-like toughness so prints are easier to manage yet more durable in service.
• Enhanced toughness: Parts printed with this PETG show superior toughness compared with many other filaments, making them better suited to stress-bearing applications.
• High impact strength: The material resists cracking from bumps and drops, which helps printed parts last longer under real-world use.
• Clear print guidance: The package includes recommended temperature bands tied to print speed so users can dial in nozzle and bed temps for different speed ranges.
• Color variety: The 4kg bundle includes four colors (black, white, blue, red), which is convenient for prototyping and color-coding parts without ordering separate spools.

Who It's For

This bundle suits hobbyists, educators, and small production shops that use 1.75mm filament and need a mix of colors with an emphasis on durability and throughput. It is particularly appealing for those using printers capable of higher speeds and for projects that require impact resistance or functional parts rather than purely decorative models.

It is less appropriate for users who need glossy, photo-real finishes or highly color-accurate filaments; some customers reported a matte look and mixed feelings about color saturation. Also, if absolute surface gloss or ultra-fine color matching is essential, a specialty PLA or PETG formulated for gloss may be a better choice.

Pros & Cons

Pros

• Good filament quality that feeds reliably on common printers and supports high print speeds.
• Strong, tough finished parts with better impact resistance than many standard filaments.
• Value-packed 4kg bundle includes four useful colors for prototyping and functional prints.
• Clear recommended temperature and speed ranges to help users optimize prints.

Cons

• Color quality is mixed for some users; the finish tends toward matte and is slightly less glossy than some PETG variants.
• Very high-speed printing may require careful temperature tuning and printer capability to match the filament's potential.

Frequently Asked Questions

Can this filament be used at very high speeds?
Yes, the material is formulated for high fluidity and can be printed up to 600mm/s, but users should increase nozzle temperature as recommended and ensure their printer can handle the speed.

Is this PETG suitable for functional parts?
Yes, the filament offers enhanced toughness and high impact strength, making it well suited for stress-bearing and functional components.

How does the finish look?
Finishes tend to be matte rather than glossy; color saturation is generally good but some users reported mixed opinions on vibrancy compared with glossy PETG.
