FLEX optimised for easier and faster printing; We’ve engineered a TPU elastomer that perfectly balances printability, flexibility, and toughness. It has a hardness of 95A, ideal for applications that demand the qualities of rubber and chemical resistance. MakerHero FLEX is a semi-flexible material that can be employed in a wide range of engineering applications where performance is more important than aesthetics. Although most flexible filaments are challenging to print, the FLEX Series is optimised for easier and faster printing without compromising layer bonding.
