Flexible filament is often described as rubbery. PolyFlex is the best known flexible filament. This type of filament can be bent and stretched very often after which it returns to the shape in which it was printed. Good layer adhesion is essential to ensure that it does not tear.
Flexible Filament
Flexible filament is a special material that contains rubber or other elastic additives, which makes the printed parts resilient. It can be used for gears and printing various models, such as shoes or hands. The flexible filament can be held in place with brackets. Also, our flexible filament is a perfect example of how we turn our experience into practical solutions for real life. It is user-centric, which means it has been carefully designed for great user experiences. This material is easy to contain because it moves in all directions. This makes flexible filament perfect for any project. It is formed into easy-to-grip spirals and stretches to help you create 3D printing experiences that are comfortable and intuitive.
When you are going to print with a flexible filament such as PolyFlex, it is wise to turn off the "retraction". With flexible filament, the “retraction” can cause the filament to come out of the extruder poorly or not at all.
Make sure the flexible filament is dry. When moisture gets into the filament, this can cause holes in the print result. We therefore recommend that you store the filament in a sealed bag containing moisture absorbers.
In addition, it is wise not to print flexible filament too quickly. A print speed of about 30mm/s is often recommended. We recommend experimenting a bit with this. Since the settings for each 3D printer can be slightly different.
The first layer is always important with 3D printing. This is certainly the case when you are going to print with flexible filament. Therefore, make sure that your print bed is properly calibrated. To improve the first layer adhesion you can use BuildTak or painters tape. In addition, it is important that the distance between the nozzle and the print bed is perfect. If the distance is too large, the flexible filament will not make good contact and will not stay in place. If the distance is too small, the flexible filament will smear the layers and will not adhere well. Without good layer adhesion, the risk of cracks is very high when the object is bent or stretched. That is why the correct adjustment is so important when you start 3D printing with, for example, PolyFlex.
With flexible filament, your 3D printing options are even more extensive. And you can make 3D prints that are not possible with other filaments. Thanks to its elastic properties, we find this a nice filament to experiment with.
Applications:
Shoe soles, smartphone cases and medical applications, flexible filament is becoming increasingly popular and used more often.
Flexible 3D printer filament is, as the name suggests, very flexible but also very durable. It also has high tensile strength and resilient properties. In general, it has long-term heat resistance and good chemical resistance.

3D printing with flexible filament can increase the possibilities of any project. Materials such as Innoflex, Flexifil and Polyflex behave in the same way as rubber. This makes them suitable for printing gaskets, stoppers and even phone cases. The types of flexible filament are a thermoplastic elastomer that can provide a perfect degree of bending, elasticity and strength for your 3D printed parts.
When to use flexible filament?
Flexible filament is best for parts that flex a little or need frequent hand washing. Because it is less rigid, it will perform well in applications where you need a little flexibility without permanent deformation, such as phone cases and other accessories. For example, if you have a mechanical part that needs a little slack so it doesn't break, flexible filament works well. Also, Flexible Filament is great when you want to print gaskets, seals, handles, feet and parts that should bend instead of break. This filament will make your 3D creations move instead of being static. What is also useful to know is that when printing flexible filament, the flexibility of the material means that it is printed at a lower temperature than standard PLA. Flexible materials may also require more experience with 3D printing to obtain desired results.
