In this video we dive into Siraya Tech's Roamr filament. This is by far one of the more unique filaments we've tested as it combines TPU with a foaming agent. This results in a material that is tunable to a wide range of shore hardnesses, and while its designed around footwear, this is just one of its many potential applications. We cover its specs, how to print with it, and I share my overall thoughts based on my time with it.
