FDM process requires support when there is an object with over hangs to avoid build failure. Analysing with different types of supports for better quality parts that has better surface finish, easy removal of support and lower support volume.
This experiment is to analyse and tabulate how the composite materials of PLA and ABS such as aluminium filled PLA or CNT filled PLA or ABS affect the part quality and how the application changes respectively.
This experiment helps in understanding how two different materials are fused by acting as supports structures since the materials are soluble. Also, to test which materials is easily soluble and which acts as a better support structure.
This experiment analysis the influence of infill percentage on mechanical properties of parts printed on FDM using different materials. In order to characterise this influence, test specimens for tensile, compression and Charpy test are to be printed on FDM machines in which infill percentage is varied and other parameters are kept constant and the results are analysed.
This experiment is to understand and analyse the parameter settings of FDM machine with respect to nozzle diameter, print temperature, bed temperature. Part quality depends on the above parameter setting. Test specimens are printed in the FDM machine and are subjected to various testing machines. The results are formulated individually.
Image processing can be applied on laser powder bed additive manufacturing for the automated detection and classification of anomalies and unwanted phenomena that can appear during the powder spreading stage. Open CV can be used to study the different layers being printed and defects can be identified.
In additive manufacturing (AM), uneven cooling and thermal deformations deteriorate the quality of manufactured parts. Warpage is a physical phenomenon that occurs during 3D printing. It consists in the part being distorted at its base, which then causes the part to detach itself from the print bed. Warpage is caused by a natural shrinkage that affects plastics when they cool. The larger the part is, the stronger the phenomenon will be. When the upper layers contract due to air cooling, they pull the lower layers upwards, which lifts the part off of the printing plate. The aim of the project is to understand the parameters which influence warpage such as temperature and thermal expansion.
The qualities of FDM-produced products are affected by various process parameters, for example, layer thickness, build orientation, or print speed. The setting of process parameters and their range depends on the section of FDM machines. The optimum setting of parameters is deemed to improve the qualities of 3D printed parts and may reduce post-production work. To test the different part properties, test specimens for tensile, compression, Izod Charpy test are to be printed on FDM machine and results are analysed.
