    Polymaker PolyFlex™ white is a highly flexible yet easy to print 3D printing material. Featuring good elasticity and a large strain-to- failure, PolyFlex™ opens up a completely new realm of applications.


    Flexible : Polymaker PolyFlex™ features a “Shore A” hardness of 90-95A and a large strain-to-failure of over 400%. These aren’t just figures on a page, but are tested values obtained from actual printed parts. What this means is that PolyFlex™ gives you cool flexible parts with no worry about the part breaking. PolyFlex™ is truly your best tool for creating fun flexible parts.

    Printer Compatibility: One of our main goals when developing PolyFlex™ was to make it easy for everyone to use. Flexible filaments are known to be difficult to work with. Well not any more. PolyFlex™ is designed to be compatible with almost all desktop FDM/FFF printers and requires no hardware modification. Not only does it print smoothly but adheres well to a large variety of surfaces with no need for a heated build plate leaving you to think about nothing other than what model your going to print.

    Flex-up Your Imagination : The soft and flexible nature of PolyFlex™ opens up a new dimension of what one can do with desktop 3D printers, clothing, shoes, wearables, prosthetics…you name it. The possibilities are endless.

    Build platform:
    All our products work well with common build plate surfaces such as the blue tape, Kapton tape, glass, etc. However for the best user experience, we recommend that you use our materials with BuildTak, a build plate surface designed specifically for desktop FDM/FFF printers.

    • Vacuum sealed bag to reduce moisture absorption with a resealable opening to store left over material
    • Desiccant bag to keep bag moisture-free
    • Filament clip to prevent filament from becoming entangled and possibly damage the vacuum sealed bag
    • Packed away with care in our boxes

    We also ship our filaments with an instruction sheet to help you get started in 3D printing
