10 Best Pla Filaments 2025 in the United States

The SUNLU PLA+ 2.0 filament bundle offers a solid choice for 3D printing enthusiasts looking for a reliable and versatile PLA+ filament. It comes in eight vibrant colors—ranging from classic black and white to bright sunny orange and klein blue—each spool weighing 250g for a total of 2kg. The filament diameter is a standard 1.75mm with a tight tolerance of ±0.02mm, which means it fits well with most FDM 3D printers and helps ensure consistent extrusion without clogging. SUNLU’s improved PLA+ formula is designed to be more resistant to brittleness and cracking than standard PLA, making prints stronger and more durable. This is especially useful if you want functional parts or models that last.

The filament melts quickly and flows smoothly, supporting fast print speeds up to 300mm/s, which can speed up your projects without losing quality. Recommended nozzle temperatures are between 205-220°C and the bed temperature is 50-60°C, typical for PLA+ and helpful for good bed adhesion. Another thoughtful feature is the neat winding of filaments on reusable spools, reducing tangling and waste. Vacuum packaging keeps the filament dry and ready to print.

The smaller spool size (250g each) means you’ll switch colors or spools more often compared to larger 1kg spools, which might interrupt longer prints if you need a single color. Additionally, while PLA+ offers better durability than regular PLA, it still lacks the heat resistance or flexibility of some other specialized filaments. SUNLU PLA+ 2.0 is well-suited for users who want easy-to-use, colorful, and moderately tough filament for everyday printing, including beginners and hobbyists who value smooth printing and consistent results.

The SUNLU Silk Rainbow PLA Filament Bundle is a colorful set designed for 3D printing enthusiasts who want vibrant, glossy results. Each of the 8 spools weighs 250g, fitting standard 1.75mm diameter printers with good accuracy (+/- 0.02mm), which helps prevent printing issues. What makes this bundle stand out is the Silk Rainbow filament, which changes color every 8 meters, giving your prints a smooth, shiny finish with multiple hues in one spool—great for artistic or decorative projects. It also includes light gold and silver spools to add metallic touches.

The recommended print temperature (205-235°C) and bed temperature (50-60°C) fit typical PLA settings, making it easy to use with most 3D printers. The filaments come vacuum-packed to protect against moisture, which is important for print quality. A minor consideration is that the starting color on each spool might differ from what’s pictured, so there’s some unpredictability in exact shade appearance. The spools are compact with a 140mm diameter and 36mm width, which should fit most filament holders without trouble.

This bundle suits hobbyists and crafters looking to add eye-catching silk-like shine and color variation to their prints without needing specialized printer settings. For those who prefer consistent color start points or larger spools for longer continuous prints, other options might be more appropriate. However, for users who enjoy colorful, glossy prints in manageable spool sizes, this is a versatile and reliable choice.

The SUNLU PLA+2.0 3D Printer Filament Bundle offers a variety of strengths for 3D printing enthusiasts, particularly due to its improved durability and resistance to brittleness compared to standard PLA+. Each spool in the bundle has a diameter of 1.75mm with a tight tolerance of +/- 0.02mm, ensuring high compatibility with most FDM 3D printers and providing precise prints. The bundle includes eight different colors (black, white, grey, blue, red, yellow, olive green, and orange), making it suitable for a wide range of projects from decorative items to functional parts. The vibrant colors and neat winding of the filament help avoid tangling issues during printing, providing a smooth experience for both beginners and experienced users.

The recommended print temperature ranges from 205-220°C, with a bed temperature of 50-60°C, which is quite standard and should work well with most setups. Additionally, the filament supports fast printing speeds up to 300mm/s, which is beneficial for quickly completing large projects. However, each spool contains only 0.25kg of filament, which might be insufficient for very large prints or high-volume production without frequent spool changes. The vacuum packaging helps to keep the filament moisture-free, ensuring consistent quality over time.

This bundle is best suited for those looking for a reliable, versatile filament with multiple color options and are okay with managing smaller spool sizes.
