This paper provides an overview on the main additive manufacturing/3D printing technologies suitable for many satellite applications and, in particular, radio-frequency components. In fact, nowadays they have become capable of producing complex net-shaped or nearly parts materials that can be directly used as functional parts, including polymers, metals, ceramics, and composites. These represent solution low-volume, high-value, highly products.
In this paper, a characterization of an AlSiMg alloy processed by direct metal laser sintering (DMLS) is presented, from the analysis starting powders, in terms size, morphology and chemical composition, through to evaluation mechanical microstructural properties specimens built along different orientations parallel perpendicular powder deposition plane. With respect similar aluminum as-fabricated, higher yield strength about 40% due very fine microstructure, closely related mechanisms...
Coupling the photoreduction of a metal precursor with 3D-printing technology is shown to allow fabrication conductive 3D hybrid structures consisting nanoparticles and organic polymers shaped in complex multilayered architectures. are fabricated incorporating silver nitrate into photocurable oligomer presence suitable photoinitiators exposing them digital light system.
Experimental evidences are reported on the potential of direct metal laser sintering (DMLS) in manufacturing flat and finned heat sinks with a remarkably enhanced convective transfer coefficient, taking advantage artificial roughness fully turbulent regime. To best our knowledge, this is first study where by DMLS investigated terms such thermal performances. On rough surfaces, we experience peak 73% for enhancement (63% average) compared to smooth surfaces. (single) performance found be 40%...
Inconel 625 (IN625) is a Ni superalloy ideal for the aeronautic and aerospace industries because of its superior mechanical corrosion resistance properties. However, production components with complex geometries by traditional processes very expensive, so additive manufacturing (AM) technologies can be applied to reduce costs. In this work, IN625 alloy processed two different AM processes: selective laser melting (SLM) metal deposition (LMD). First, powders are characterized, then parameter...
Additive manufacturing technologies are currently envisaged to boost the development of a next generation microwave and millimeter-wave devices intended for, among others, satellite telecommunications, navigation, imaging, radio-astronomy, cosmology. Due their excellent electromagnetic mechanical properties, all-metal waveguide components key building blocks several radio frequency (RF) systems used in these application domains. This article reports on prospects originating from 3D printing...

In this work, three-dimensional (3D) structured hybrid materials were fabricated combining 3D printing technology with in situ generation of inorganic nanoparticles by sol–gel technique. Those materials, consisting silica nanodomains covalently interconnected organic polymers, printed complex multilayered architectures, incorporating liquid precursors into a photocurable oligomer the presence suitable photoinitiators and exposing them to digital light system. A post treatment acidic vapors...
In contemporary society we observe an everlasting permeation of electron devices, smartphones, portable computing tools. The tiniest living organisms on Earth could become the key to address this challenge: energy generation by bacterial processes from renewable stocks/waste through devices such as microbial fuel cells (MFCs). However, application solution was limited a moderately low efficiency. We explored limits, if any, additive manufacturing (AM) technology fabricate fully AM-based...
Sponge-like nanostructured ZnO layers were successfully employed as photoanodes for the fabrication of highly efficient dye-sensitized solar cells. The sponge-like obtained by room temperature radio-frequency magnetron sputtering deposition metallic zinc, followed thermal oxidation treatment in an ambient atmosphere. porous films show a 3D branched nanomorphology, with feature similar to natural coral. morphological and optical properties these studied through field emission scanning...
