As the main purpose, of the same project, we focus on 3D printing applications.
This manufacturing tool allows us to create printed circuit structures within the
microwave range of microstrip technology. It is well known that in this type of
transmission line, prior calculations must be carried out to define the characteristics of
the device. In this calculation process, we need to choose our insulating material
according to the desired frequency and phase, and depending on the properties of the
substrate, we obtain values involving many factors such as the distance between planes
of the cross-section [1], the width or distance of the track, etc. However, the choice of
insulating material involves many properties that we must be familiar with.
In this project, we apply a resonant method to characterise the dielectric material
used as filament in 3D printing. The aim of the characterisation is to determine the
dielectric properties of each material (PLA, ABS, Preperm3), with the most relevant
properties being relative permittivity and loss tangent. To carry out this method and be
able to model these materials, we present all the parts involved in this research
development, structured into 5 chapters.
In the first chapter, a clear introduction to the Final Degree Project is provided,
along with an explanation of the objectives set out.
In the second chapter, the theoretical framework in which we are working is
outlined, explaining what 3D printing is and its different technologies, the physical
relationship involved in resonant devices, microstrip technology, and high-frequency
resonance, which is the method used for characterisation.
In the third chapter, the different methods used in the various development
procedures are presented in a classified manner, along with the characteristics of the
materials used for 3D printing and the software and measurement tools employed.
In the fourth chapter, the evolution of the development is transparently reflected
through different phases, including design, manufacturing, measurement,
characterisation, and results.
Finally, in the fifth chapter, all the conclusions and analyses from the entire
development of this project, with mention of improvements and future research
directions.
