A pull through such as might be used for an endoscope where a thermoplastics monofilament substantially free of spool or coil memory has moulded thereon a desirable thermoplastic mass profile in a material of lower melting point than at least part of the filament, such melting point differential with preferably pre-heating of the filament. Experiments axe described in which the bending modulus of several monofilament materials was determined at different constant humidities and varying temperature and at different constant temperatures and varying humidity. Continuous operating temperature. The dependence on thermoplastics as a feedstock by ME3DP platforms limits the applicability of this additive manufacturing method. A thermoplastic filament comprising multiple polymers of differing flow temperatures in a regular geometric arrangement, and a method for producing such a filament, are described. .
