PLA Filament 1.75mm 1kg Rainbow Multicolor - Mermaid PLA

In this review of the PLA Filament 1.75mm 1kg Rainbow Multicolor Mermaid PLA, the bottom line is simple: this spool is best for makers who want eye-catching, multicolored prints without swapping filaments. It is particularly appealing to hobbyists and small-scale creators who print toys, figurines or decorative pieces and want smooth extrusion and reliable feeding. The single biggest reason to buy is the gradual purple-to-blue-to-green color transition that yields elegant, multicolor surfaces from one spool while maintaining the ease of use associated with PLA filament.

Key Features

• Rainbow color transition: The filament fades from purple to blue to green so prints can show natural color shifts without changing spools.
• Universal compatibility: Works with most 1.75mm printers and 3D pens such as Creality, Prusa, Ender, ANYCUBIC and Flashforge for broad usability.
• Smooth extrusion: The material feeds consistently and extrudes without frequent clogging, which reduces failed prints and nozzle maintenance.
• Durable PLA material: Made from natural PLA that is stronger with higher adhesion than some silk-type rainbow filaments, improving part durability.
• Good surface finish: Prints yield attractive, elegant color blends and smooth surfaces that suit toys, miniatures, and decorative models.

Who It's For

This filament is aimed at hobbyists, educators and small business makers who want to produce visually striking items without managing multiple spools. It is ideal for projects like dragons, toys, figurines and display pieces where the gradual color change enhances the final appearance.

It is less suitable for users who need very rapid color transitions on tiny parts or who require specialty engineering plastics for high-temperature or load-bearing applications; those users should consider different materials tailored to mechanical performance or faster color-change techniques.

Pros & Cons

Pros

• Attractive multicolor transition that produces elegant, eye-catching prints.
• Compatible with a wide range of 1.75mm printers and many 3D pens for flexible use.
• Consistent feeding and smooth extrusion reduce printing problems like jams.
• Natural PLA composition offers good adhesion and improved strength over some novelty silk filaments.

Cons

• Color change is gradual, so small single-piece prints may only show one color and customers report mixed feelings about the speed of change.
• Not intended for high-temperature or heavy structural parts where engineering filaments are required.

Frequently Asked Questions

Will this filament work in my 1.75mm printer?
Yes. It is designed for 1.75mm systems and is compatible with common models like Creality, Prusa, Ender, ANYCUBIC and Flashforge.

How noticeable are the color changes on small prints?
Color transitions are gradual; small single-piece prints may only contain one color, so printing multiple items or larger parts produces more visible shifts.

Is this filament strong enough for functional parts?
It is PLA with improved adhesion and strength over some novelty silk filaments, but it is not a substitute for engineering plastics when high heat resistance or heavy load-bearing is required.
