Multi Objective Optimization of Built Orientation For Rapid Prototyping Of Connecting Rod

The ability to select the optimal orientation of build-up is one of the critical factors since it affects the part surface quality, accuracy, build time and part cost. Various factors to be considered in optimization of build orientation for FDM are build material, support material, build up time and total cost. Experiments were carried out on FDM machine and results are analysed for varying build orientation for connecting rod. An appropriate weighting factor has been considered for various objective functions depending on the specific requirement of the part while carrying out multi-objective optimization. These analyses will help process engineers to decide proper build orientation. So, it is necessary to analyse the object manufacturing at different build orientation by rapid prototyping to know about the efficient build orientation so that the manufacturer should get minimum cost of manufacturing and the best accuracy.
