Abstract
Selective Laser Sintering, and in general Additive
Manufacturing Processes are becoming mature technologies; in the
sense that after many years of market introduction there are some
well-known manufacturers that provide fully operative systems that
are even utilized for direct parts manufacturing. However, the parts
final users are becoming more and more demanding, so they can
integrate the AM parts in complex assemblies; thus increasing the
materials requirements and the final part’s properties.
Building into previous works on AM materials, the purpose of the
present paper is to explore the properties yielded by the introduction
of Glass short fibre randomly to polyamide and to assess the
performance of the probe parts taking into consideration the AM
manufacturing direction in the building platform and the Energy
Density applyied to the operations. Folowing to a literature review,
the paper first describes the statistical approach and the samples
preparation. Then, the samples are characterized by tensile tests and
the properties of the material are described for the different
manufacturing strategies adopted.
The outcomes of the work are highly applicable to the AM parts
manufacture process, as the construction of parts in the building
platform is usually dictated by the objective of optimizing the use of
the total volume; thus implying that not all parts are manufactured in
the same main construction direction.
