“…Additive manufacturing, including 3D printing, has been on the rise for several years [1]. Many successful attempts have been made to design and manufacture various devices and structures using 3D printing [2] and other additive manufacturing techniques [3,4]. 3D printing has gained popularity because of its low complexity, low initial costs and huge potential for fast prototyping.…”

This paper presents a basic study of the possible application of roughness parameters for monitoring of the life cycle of 4D printed structures. Experiments were performed with the purpose of gaining some insight into a novel manufacturing technique that may be of future interest and to investigate measurement procedures which may be helpful in the effectively monitoring, maintenance and design of 4D structures. This article describes changes in certain roughness parameters, i.e., Ra, Rsk, RSm, and Sa during the repeated bending of 4D printed beams. The quantitative values of these parameters are also provided and discussed.

“…This paper describes in detail the design, manufacture and measured results of a fully 3-D printed 4-element steerable phased-array antenna subsystem [24]. Here, 26 circuit elements (1× flange, 6× mitred bends, 3× power splitters, 4× tunable delay lines, 4 × 90 • waveguide twists, 4× bent interconnects and 4× H-plane sectoral horn antennas) are manufactured as a fully integrated, complete, subsystem.…”

This paper introduces the first fully 3-D printed tunable microwave subsystem, consisting of 26 circuit elements. Here, a polymer-based 3-D printed Ku-band 4-element steerable phased-array antenna with fully integrated beam-forming network is demonstrated. Polyjet was adopted for fabricating the main body of the subsystem, as it is capable of producing a geometrically complex structure with high resolution over a large volume. Low-cost fused deposition modeling was chosen to manufacture the dielectric inserts and brackets for the phase shifters. The measured radiation pattern revealed that the phased-array antenna subsystem has total beam steering angles of 54 • and 52 • at 15 GHz and 17 GHz, respectively. Excellent input return loss behavior was observed across the optimum operational frequency range of 15 to 17 GHz, with a worst-case measured return loss of 12.9 dB. This work clearly shows the potential of using 3-D printing technologies for manufacturing fully integrated subsystems with complex geometric features.
