Abstract Additive manufacturing (AM), adding materials layer by layer, can be
used to produce objects of almost any shape or geometry. However, AM techniques cannot accurately build parts with large overhangs, especially for the large
features close to horizontal, hanging over the void. The overhangs will make
the manufactured model deviate from the design model, which will result in
the performance of the manufactured model that cannot satisfy the design requirements. In this paper, we will propose a new finite element (FE) analysis model
that includes the manufacturing errors by mimicking the AM layer by layer construction process. In such FE… More >
