“…The boundary between newly created and existing material can act as an interface where cracks and other types of failure can initiate. Since the discretization in modern AM processes is rarely isotropic, the surface roughness and resulting material properties [113][268] [274] are also usually anisotropic. One common method to address these anisotropies is to modify the part [25][118] [328] or assembly [232] orientation to minimize their impact.…”

The past few decades have seen substantial growth in Additive Manufacturing (AM) technologies. However, this growth has mainly been process-driven. The evolution of engineering design to take advantage of the possibilities afforded by AM and to manage the constraints associated with the technology has lagged behind. This paper presents the major opportunities, constraints, and economic considerations for Design for Additive Manufacturing. It explores issues related to design and redesign for direct and indirect AM production. It also highlights key industrial applications, outlines future challenges, and identifies promising directions for research and the exploitation of AM's full potential in industry.Design, Manufacturing, Additive Manufacturing

“…Lee et al (2005) concluded that layer thickness, raster angle, and air gap influence the elastic performance of compliant ABS prototypes manufactured by fused deposition. A study conducted by Es Said et al (2000) analyzed the effect of raster orientation and the subsequent alignment of polymer molecules along the direction of deposition during fabrication. These researchers considered the issue of volumetric shrinkage and raster orientation with respect to tensile, flexural and impact strengths.…”

“…Among these, building orientation significantly influences productivity factors such as manufacturing time [12]. On the other hand, there is a direct relation between building orientation and the alignment of polymer molecules along the direction of sheet deposition during manufacturing [13]. That is, tensile, flexural and impact strength depend on building orientation in LOM processes.…”

Influence of building orientation on the flexural strength of laminated object manufacturing specimens

This paper aims to define the best building orientation for parts manufactured with the laminated object manufacturing technique (LOM), to enhance their flexural performance. Previous research has shown that parts manufactured with LOM have the ability to withstand higher deflections than components created through other layer manufacturing techniques, but, so far, no relation between the building orientation and flexural strength of parts has been assessed.Four types of specimens have been manufactured, each of them using a different building orientation. They have been tested in a fourloading-points machine to evaluate their failure mode, and extract a conclusion of the best building orientation towards flexural load. 45 degrees was found to be the best building orientation in terms of maximum load before failure. Furthermore, a repetitive failure pattern was found for each tested condition. It is confirmed that building orientation is a relevant parameter in LOM manufacturing with influence on the mechanical properties of parts.
