Summary

3D Printing or Digital Fabrication is one of the fastest emerging technologies in the manufacturing industry. It is widely being used for the mass customization and fabrication of any type of geometrical design. Out of all 3D Printing techniques available, Fused Deposition Modelling is dominating the printing industry with its flexibility in materials for printing. It is widely being used in industries like aviation, healthcare, agriculture, and the automotive industry with a versatility in materials from thermoplastics to metals. However, the parts fabricated with FDM are still widely being used in prototyping, models, etc. and not in actual manufacturing industries for high-end products. This is because of the low strength of the parts which are not reliable for end-products. The introduction of fiber composites in FDM has solved this problem to a great extent by providing great improvements in mechanical properties of the printed products, but the performance of the FDM printed products is still low when compared to conventional machining processes. Numerous defects occur during the fabrication of these parts leading to undesirable properties. This chapter aims to present the materials compatible with FDM, the various process parameters, and the mechanical properties of the 3D printed parts printed via FDM.
