When the content of the reinforcement is 10%, the composites exhibit the best mechanical properties, meanwhile, it demonstrate cluster is unfavorable to the improvement of properties of materials.
Mechanical properties and fractographs.
The mechanical properties of Al matrix composites are mainly attributed to the interface bonding state and distribution of whiskers in the matrix [7,8].
That is because there are other factors that affect the strength of the composites, including the clustering and lower aspect ratio of the whisker.

Influence of Built Orientation on Mechanical Properties in Fused Deposition Modeling Sandeep V.
In FDM, one of the critical factor is to select the built up orientation of the model since it affects the different areas of the model like main material, support material, built up time, total cost per part and most important the mechanical properties of the part.
In view of this, objective of the present study was to investigate the effect of the built-up orientation on the mechanical properties and total cost of the FDM parts.
In order to be used as a part for serial production, the components must possess the required mechanical properties.
