Abstract 3D Printing, also called Additive Manufacturing, has become a promising manufacturing method to produce parts in various fields as it can produce parts even with very irregular shapes in a relatively shorter process and time. However, during the printing process, some problems could decrease the accuracy and quality of the printed parts, such as warpage due to thermal strains, deformation due to inadequate supports, etc. The finite element method is most commonly adopted to evaluate engineering problems in advance to reduce possible failures; however, the element meshes, needed for analyses, are always irregularly distributed, especially for irregular objects, and cannot… More >
