InsoleFlex 9585A Filament

InsoleFlex 9585A is a specialised TPU built specifically for 3D printed insoles and wearable cushioning. It is rated 95A on the spool, but a special compound reacts to the heat of printing and softens it to around 85A once printed, giving you genuine cushioning without the difficulty of ultra-soft filaments. We currently stock it in four colours, all in 1.75mm, 750g spools, held locally in Australia.

Why Choose InsoleFlex 9585A?

This sits in a genuine sweet spot: softer underfoot than standard TPU, but far easier to print than ultra-soft filaments. You get real cushioning without fighting your printer to get there.

  • Rated 95A on the spool, softens to around 85A once printed for genuine cushioning
  • Easier to print than ultra-soft TPU grades
  • Strong layer adhesion for durable wearable parts
  • Four colours to choose from

Best Uses for InsoleFlex 9585A

This one earns its keep on anything that needs real cushioning against the body:

  • Custom footwear inserts and insoles
  • Orthotics and ergonomic supports
  • Sandals and wearable products
  • Shock absorbing comfort parts

Comparing Our Flexible Filaments

We stock several flex materials, and the hardness rating on the spool only tells half the story:

  • InsoleFlex 9585A: 95A on the spool, softens to around 85A once printed, built specifically for insoles and cushioning
  • ShoeFlex 9075A: 90A on the spool, softens further to around 75A once printed, the softest option for direct skin contact wearables
  • TPU 95A: 95A on the spool and stays 95A once printed, the firmest and most durable, best for cases and structural flexible parts
  • FPLA: a rigid flex PLA rather than a true TPU, easier to print for parts that need to spring back to shape rather than feel soft

Printing with InsoleFlex 9585A

It prints easier than most soft TPUs, but still benefits from a few adjustments:

  • Direct drive extruders recommended for best results
  • Slower print speeds improve consistency
  • Reduced retraction helps minimise stringing
