TPE and TPU flexible filaments
TPE and TPU are flexible materials that combine flexibility and strength. In 3D printing, they are used when the resulting product must be strong and flexible at the same time.
The main difference between the two filaments is flexibility. TPE is softer and more flexible, but it is more difficult to print with due to its poor adhesion to the printing pad.
Have you already tried printing with basic filaments such as ABS or PLA and are now attracted to flexible materials? Then you are in the right place. Whether flexible filament is an unexplored area for you or you have already had the honor of using it, in the article you can read, among other things, what are the advantages and disadvantages of flexible filament and what the Shore scale (hardness scale) indicates.
