Flexible 3D Printing Materials

Flexible 3D Printing Materials can take a number of different forms. Many polymers are flexible, for instance PET (bottles), Polyimide (Flex PCB), TPU, TPE and blends such as Ninjaflex. Material properties can be quantified through the use of tensile or compression tests – with highly flexible materials generally having a large elongation at break and low Young’s modulus. Below is a table with many of the filaments available on the market today:
