PLA Plus 1.75mm Filament 4-Pack - Reliable PLA+ for FDM Printing

In this review of the SUNLU PLA Plus 1.75mm filament 4-pack, the bottom line is straightforward: this set is best for hobbyists and small workshops that want a variety of test colors and generally reliable PLA+ prints at a good price. The review finds the spool bundle offers solid filament quality and accurate color for test parts, while noting occasional issues with adhesion and spool size on some machines. For those who print routine prototypes and color checks, the package delivers value with a modest caveat about compatibility with printers that need larger spools.

Key Features

• PLA+ formulation: Delivers stronger, less brittle prints than standard PLA, useful for functional prototypes and display pieces.
• 1.75mm diameter: Matches the common filament diameter of most FDM printers so it can be used without nozzle modification on many machines.
• Four 1kg spools: Provides four different colors in a single purchase to speed color testing and part variation without frequent reorders.
• Neatly wound rolls: The tidy winding reduces the chance of tangles when feeding filament, helping keep prints uninterrupted in most setups.
• Color accuracy: The black, olive green, yellow, and silver options reproduce expected hues well, which is handy for test prints and visual prototyping.

Who It's For

This filament pack suits hobbyists, educators, and makers who run FDM printers and want a cost-effective way to test multiple colors or produce small runs of parts. It is especially good for users of desktop machines that accept 1kg spools and benefit from a stiffer PLA+ for better dimensional stability.

Those who should look elsewhere include operators of printers that require larger spool diameters or specialized filaments for high-temperature applications. If you need guaranteed perfect adhesion across every bed surface or industrial grade spool sizes, consider alternatives tailored to that requirement.

Pros & Cons

Pros

• Filament quality generally prints cleanly and yields good surface finish on typical FDM setups.
• Accurate color reproduction makes it simple to evaluate colors for prototypes without surprises.
• Provides good value by bundling four distinct colors in one purchase for testing and small projects.

Cons

• Size and spool dimensions were criticized by some users who found the spool too small for their machine setups, so check compatibility first.
• Adhesion and roll quality received mixed feedback, with occasional binding reported on certain printers.

Frequently Asked Questions

Will this filament fit my desktop FDM printer?
It is 1.75mm diameter and intended for most FDM machines, but confirm your spool holder accepts 1kg spool dimensions.

Is adhesion to the print bed reliable?
Adhesion is generally good, but customer reports are mixed; some users saw binding or adhesion issues depending on printer and bed surface.

Are the colors true to description?
Customers report accurate color reproduction for testing and prototyping, making the set useful for visual checks.
