Characterisation of the behaviour of 3D printed spring-strips-based compliant elements

Cilj diplomskog rada je ispitati karakteristike podatljivih elemenata dobivenih FDM tehnologijom 3D tiska za različite dimenzije i materijale. Nakon analize dostupne literature i znanstvenih radova, odabran je analitički model ponašanja podatljivog elementa te je osmišljen i konstruiran eksperimentalni postav pomoću kojega je ispitana ovisnost narinute sile o pomaku slobodnog kraja lisnate opruge te promjena horizontalnog pomaka. Nakon prikupljanja podataka, analizirani su rezultati eksperimenta za sve uzorke, uspoređena je međusobna ovisnost parametara te su izvedeni zaključci. Rezultati, s obzirom na vrlo jeftine komponente, su bili vrlo zadovoljavajući te uz daljnja testiranja i modeliranja s preciznijom opremom se može doći do još boljih rezultata te prikladnijih modela za podatljive mehanizme dobivenih FDM tehnologijom 3D tiska.The goal of this master's thesis is to test the characteristics of FDM produced compliant elements with varying dimensions and materials. After the analysis of the available published works based on this topic, an mathematical behaviour model was chosen and an experiment was designed to test the relationship between the actuating force of the compliant element and the vertical and horizontal displacement. After data aquisition, the data was analysed, the relationship between the dana was compared and a conclusion was made. The results, while being produced by cheap hardware, were very satisfactory and with further testing using more expensive and precise hardware, better and more precise results and mathematical models of behaviour can be made specifically for FDM made compliant mechanisms
