Flexible PLA Filament 1.75mm - Soft, 89A Shore, 1kg Spool

In this review of the Flexible PLA Filament 1.75mm the bottom line is simple: this spool is aimed at makers who need a soft, highly stretchable material that is easier to print than TPU. The filament's patented formula delivers an elastic behavior with roughly 500-600% elongation at break and an 89A shore hardness, making it a strong choice for flexible parts like phone cases, wearables, shoe insoles and soft decorations. The reviewer found it prints reliably on both Bowden and direct drive setups and appreciates the included resealable storage bag for moisture protection.

Key Features

• Patented flexible formula: Provides exceptional elongation and resilience so printed parts stretch up to five to six times more than typical filaments.
• Soft 89A shore hardness: Produces pliable, rubber-like prints suitable for functional flex items such as belts, insoles and gaskets.
• Bowden and direct drive compatible: Works with most FDM printers including Bowden setups that often struggle with TPU, simplifying use across many machines.
• Dimensional accuracy: Supplied in 1.75 mm diameter with tight tolerance (+/- 0.03 mm) for consistent extrusion and fewer print issues.
• Clog and bubble resistant: The formulation and spool winding reduce tangles, bubbles and clogs for smoother printing runs.
• Storage solution included: Each spool ships sealed with desiccant and a reusable vacuum storage bag to protect filament from moisture.

Who It's For

This filament is best for hobbyists, makers and small workshop users who want flexible, soft parts but prefer an easier-to-print option than TPU. People making wearable items, grips, phone cases, art projects and prototype flexible parts will benefit most from the high elongation and forgiving feed behavior.

It is less suited to those who need very high-temperature materials, rigid structural parts or exact color-critical industrial finishes; color matching can vary between lots, so users requiring precise pantone-level color control should test samples first.

Pros & Cons

Pros

• Very high elongation and soft feel make it ideal for flexible functional prints.
• Reliable across Bowden and direct drive printers, reducing setup headaches.
• Consistent diameter and clean winding lower the chance of jams and print failures.
• Includes resealable vacuum bag and desiccant for longer shelf life.

Cons

• Color results can be mixed for some shades, so expect variation versus the pictured panton match.
• Some users report stringing or occasional adhesion quirks that require slicer tuning.

Frequently Asked Questions

Will this work on a Bowden extruder?
Yes, the filament is formulated to run reliably on both Bowden and direct drive systems.

What print temperature should I use?
Start around 190-210 C and adjust within that range for flow and adhesion on your machine.

How should I store unused filament?
Keep spools sealed with desiccant or in the provided vacuum storage bag to prevent moisture absorption.
