Flexible PLA Filament 1.75mm 1Kg Spool - Flexible, Easy to Print

In this review the focus is on a flexible PLA filament aimed at makers who need a soft, stretchable material that prints more easily than TPU. The bottom line: this filament is best for hobbyists and small-batch product makers who want very high elongation and reliable spool handling, because its patented formula delivers about 500-600% elongation and a consistent diameter that reduces jams. For users who need rigid engineering plastics or exact Pantone-matched colors, it may not be the ideal choice.

Key Features

• Patented flexible formula: The proprietary blend yields an 89A shore hardness and extreme elongation so printed parts stretch up to five to six times their length without breaking.
• Easy to print compared with TPU: The filament is formulated to run smoothly through both Bowden and direct drive extruders, lowering the risk of feeding issues common with softer thermoplastics.
• Dimensional accuracy: Spools are manufactured to a tight tolerance of +/-0.03 mm at 1.75 mm so layer flow and extrusion remain consistent across long prints.
• Wide color range: The line is offered in many Pantone-like colors, making it useful for visual projects where variety is more important than absolute color code matching.
• Moisture protection and storage: Each spool is sealed with desiccant and the package includes a reusable vacuum storage bag to keep filament dry and reduce bubbles or clogs.
• Printer settings guidance: Manufacturer suggests 190-210 C nozzle temperature, 0-40 C bed temperature and 60-90 mm/sec print speed, with 0.4-0.6 mm nozzle recommendations.

Who It's For

This filament is aimed at makers printing flexible objects like shoe insoles, phone cases, belts and decorative parts where stretch and soft touch are priorities. It is particularly helpful for users who struggled with TPU feeding in Bowden setups because this flexible PLA was designed to be easier to push through both Bowden and direct drive extruders.

Professionals who need hard engineering plastics, exact color certification, or high-temperature resistance should look elsewhere; rigid materials and specialty filaments still outperform flexible PLA in load-bearing and thermal applications.

Pros & Cons

Pros

• Excellent elasticity and soft feel, making it suitable for wearables and impact-absorbing parts.
• Works reliably on both Bowden and direct drive systems, reducing the setup hassle for many printers.
• Tight diameter tolerance (+/-0.03 mm) helps produce consistent extrusion and fewer under/over-extrusion issues.
• Includes vacuum storage bag and sealed packaging to reduce moisture-related print defects.

Cons

• Color consistency is mixed for some hues, so exact Pantone matches may not be guaranteed.
• Some users report stringing or occasional adhesion variability, so tuning retraction and temperature may be required.

Our Verdict

This flexible PLA is a compelling choice for makers who need very elastic, easy-to-print flexible parts without the feeding headaches of TPU; it combines strong elongation, consistent diameter and useful storage packaging to deliver reliable prints. For projects requiring rigid strength or absolute color matching, select a different filament, but for soft wearables and flexible prototypes this filament offers good value.

Frequently Asked Questions

Will this filament work on a Bowden extruder?
Yes. The formula is designed to feed reliably on both Bowden and direct drive extruders.

What printing temperature is best?
Follow the suggested range of 190-210 C and tune within that window for your printer and nozzle size.

How should I store leftover filament?
Keep the spool sealed with desiccant or in the provided vacuum storage bag to prevent moisture absorption and bubbles.
