Abstract

Dodajalne tehnologije oz. 3D tisk prinašajo nove možnosti za izdelavo aktuatorjev, izdelanih iz polimerov s spominskim efektom. V zaključnem delu smo zasnovali eksperiment in izdelali preizkuševališče za meritev spominskega efekta 3D natisnjenih vzorcev. Iz polimera s spominskim efektom SMP55 in električno prevodnega materiala Protopaste smo natisnili aktuator z integriranim gretjem. Izmerili smo vrednost največje sile tekom cikla spominskega efekta, čas od začetka segrevanja do dosega največje sile, razmerje fiksnosti oblike, razmerje povračljivosti oblike in deformacijo tekom cikla spominskega efekta v neobremenjenem stanju.

Secondary title: Shape memory polymer 3D printed actuators
Secondary abstract: Additive manufacturing or 3D printing offers new possibilities for the production of shape memory polymer actuators. In the final thesis, we designed an experiment and built a test rig for measuring the memory effect of 3D printed samples. We 3D printed an actuator with integrated heating from shape memory polymer SMP55 and electrically conductive filament Protopasta. We measured the value of the maximum force during the shape memory cycle, the time from the start of heating to the achievement of the maximum force, the ratio of shape fixity and the ratio of shape recovery and deformation during the unrestrained shape memory cycle.
