Special Issue Information

Dear Colleagues,

Additive manufacturing, also known as 3D printing, is one of the most groundbreaking technologies developed in the last few decades. Its main concept is the creation of complex objects in a layer-by-layer fashion following a digital model. Unlike traditional subtractive methods, which typically remove material from a solid block, additive manufacturing adds material only where needed, reducing waste significantly. This technology allows for the production of complex geometries that would be difficult or impossible to achieve using conventional methods. Thanks to its flexibility, customization and on-demand production capabilities, it constitutes one of the main pillars of Industry 5.0.

In addition to 3D printing, many other technologies have the potential to significantly contribute to the advancement of manufacturing processes. These include, for example, material jetting techniques like inkjet printing or aerosol printing, based on the controlled deposition of materials in the form of fluids. Thanks to their precision, scalability and optimal material usage, material jetting represents one of the most promising approaches for sustainable production in a wide variety of industrial fields, such as microelectronics, sensors, optics, bioengineering, etc. Furthermore, material jetting techniques represent the ideal candidate for potential synergies with 3D printing processes, giving rise to highly efficient and versatile hybrid approaches.

Starting from these considerations, this Special Issue serves as a comprehensive platform for presenting and discussing cutting-edge advances in this promising topic. It is open to both original research articles able to advance knowledge on a wide variety of advanced manufacturing technologies and to reviews meant to take stock of state-of-the-art literature.

A list of the possible topics, though not exhaustive, includes the following:

  • Three-dimensional printing/material jetting of soft and biomaterials;
  • Additive manufacturing/material jetting for electronics and metamaterials;
  • New materials for 3D printing (metals, composites, hard materials, ceramics, etc.);
  • Additive manufacturing/material jetting for batteries and energy storage;
  • Printing process monitoring and in situ characterization;
  • Multi-material 3D printing;
  • Integration of material jetting processes and 3D printing technologies;
  • Metallization for 3D printing;
  • Three-dimensional printing for microfabrication;
  • Numerical and finite element modelling of additive manufacturing processes.

Next-generation flexible, soft, and stretchable sensors and electronic devices are conquering the technological scene due to their extremely innovative applications. Especially when produced via innovative technologies like additive manufacturing (AM) and/or inkjet printing (IJP), they represent an undeniable strategic asset for Industry 5.0. Within the growing sensor market, they offer advantages in terms of sensitivity and maximum sensing range. In addition, the use of AM/IJP reduces material waste, enhances scalability, and lowers cost production. In the present work, the design and fabrication of a highly flexible inkjet-printed piezoelectric sensor on top of a thin highly flexible polyimide substrate are presented. The silver top and bottom electrodes were inkjet-printed together with a P(VDF-TrFE) active layer with a nominal thickness of 3 μm which is located between them. The experimental results demonstrate that, even in extreme bending conditions and at different bending speeds, the fabricated sensors are able to maintain their performance without mechanical delamination, giving a stable and repeatable output peak-to-peak signal of 850 mV under cyclic bending. The material combination and the IJP-based fabrication technique employed for the first time in this work to produce highly flexible sensors represent a promising novelty in terms of both sensor performance and customization possibilities.
