Flexible PLA Filament 1.75mm 1kg Slate Gray - Flexible, Easy to Print

Our review of this Flexible PLA 1.75mm filament finds it best for hobbyists and small-scale makers who want a soft, stretchable material that prints more easily than TPU. The single biggest reason to buy is the patented formula that delivers about 89A shore hardness and exceptionally high elongation at break, making parts that stretch five to six times their length while remaining compatible with both Bowden and direct drive setups. For those who need a forgiving flexible filament that is clog resistant and comes with a resealable storage option, this filament stands out.

Key Features

• Patented flexible formula: Provides an elastic, TPU-like feel with roughly 89A shore hardness for durable, stretchable prints.
• High elongation: The filament can stretch 500-600% at break, useful for wearable parts such as insoles and belts.
• Bowden and direct drive compatibility: Works with most FDM printers, including Bowden extruders where typical TPU often fails.
• Precision winding and diameter tolerance: Supplied on an auto-wound 1kg spool with 0.03 mm dimensional accuracy for reliable feeding.
• Clog and bubble reduced formulation: Produced to be tangle free and bubble free for steadier extrusion and fewer print failures.
• Storage and moisture protection: Includes sealed packaging and a premium vacuum storage bag to help preserve filament quality.

Who It's For

This filament is aimed at makers printing flexible parts like phone cases, shoe insoles, decorative belts, and soft prototypes where stretch and resilience matter. It suits users who want the feel and flexibility of TPU but need a filament that is easier to print, especially on machines with Bowden extruders.

It is less appropriate for those needing rigid engineering plastics, very high-temperature performance, or perfectly color-accurate finishes for showpieces; color fidelity can vary by hue, so consider a sample if exact Panton-matched color is critical.

Pros & Cons

Pros

• Easier to print than TPU while offering similar softness and stretch for wearable and flexible parts.
• Compatible with Bowden and direct drive systems, widening printer compatibility.
• Comes on a 1kg auto-wound spool with tight diameter tolerance, reducing feeding issues.
• Includes vacuum storage bag and sealed packaging to reduce moisture absorption.

Cons

• Color accuracy is mixed across some tones, so some colors may look different than expected.
• Stringing and adhesion behavior can be variable depending on printer settings and temperature choices.

Our Verdict

This flexible PLA is a strong pick for hobbyists and prototypers who want a soft, stretchable filament that prints more reliably than TPU and works with both Bowden and direct drive printers. It offers good value when flexibility, ease of printing, and moisture protection matter most, though prospective buyers should be aware that color tones can vary and fine-tuning may be needed to control stringing.

Frequently Asked Questions

Will this filament work on a Bowden extruder?
Yes. The formula is designed to be compatible with Bowden setups as well as direct drive printers.

What temperature should I print at?
Start in the suggested range of 190-210 C and adjust for your nozzle size; customers report some users printing at 245-250 C for different machines.

How should I store unused filament?
Keep it sealed with the included desiccant or in the provided vacuum storage bag to prevent moisture uptake and preserve print quality.
