I-Torwell FLEX iyintambo yakamuva eguquguqukayo eyenziwe nge-TPU (Thermoplastic Polyurethane), enye yama-polymers asetshenziswa kakhulu ezintweni zokuphrinta ze-3D eziguquguqukayo.Le filament yephrinta ye-3D yathuthukiswa ngokugxila ekuqineni, ekululameni nasekusebenziseni kalula.Manje zuza ezinhlelweni ze-TPU nokucubungula kalula.Impahla inokuwohloka okuncane, ukushwabana kwempahla ephansi, ihlala isikhathi eside futhi imelana kumakhemikhali amaningi namafutha.
I-Torwell FLEX TPU inobunzima be-Shore obungu-95 A, futhi inobude obukhulu ngesikhathi sekhefu lama-800%.Zuza ohlwini olubanzi kakhulu lwezinhlelo zokusebenza nge-Torwell FLEX TPU.Isibonelo, izibambo zokuphrinta ze-3D zamabhayisikili, ama-shock absorbers, ama-rubber seal nama-insoles ezicathulo.
