Abstract
Any manufacturing process which allows to create a product in its finished form without the need for
other machining operations belongs to Net Shape Forming family. Additive Manufacturing (AM) is a part
of NSF family; it allows to build 3D objects by adding layer-upon-layer of material (polymers, metals, ceramics) and includes different manufacturing techniques as stated by ISO/ASTM Standard.
In order to get good results by the application of these manufacturing techniques, some technological
problems has to be faced and solved. They mainly concern: temperature control of the material to be
processed, characteristics of the energy source for material transition, control of the power transferred
to the material, scanning system’s head control, 3D model’s layer definition, generation of the laser
point’s trajectories. All of these aspects have the same importance to guarantee the quality of the product
and they are sinergically linked each other. As an example, the power of the energy source and the
temperature of the material are strongly related; the power transferred to the material is related to the
trajectories running speed; the 3D model’s layer definition influences the resolution of the positioning
system; on the performances and control of the scanning head, depends the accuracy of the trajectories.
The quality of the product strongly depends on all these aspects as well as on the technical solution to
realize them. In other words, the machine implementing the AM technological process is crucial for the
product’s manufacturing. From the early stages of machine’s concept, a multidisciplinary and synergic
approach which allows to take into account all the different aspects involved in the process must be
followed. This is the typical approach followed by Mechatronics; as a matter of fact, Mechatronics
concerns the the synergistic application of mechanics, electronics, controls and computer engineering in
the development of product and systems through an integrated design approach.
In this paper, the fundamental aspects that must be taken into account in the design process of an AM
machine are highlighted, and the used design approach is discussed.
