3D-printed Optical Devices with Refractive Index Control for Microwave Applications

Isakov D., Wu Y., Allen B., Stevens C.J., Grant P.S., University of Warwick, UK

Achieving sub-wavelength spatial variations in the relative permittivity εr and permeability μr to control the propagation of the electromagnetic radiation opens up many opportunities for the development of new devices with improved or novel functionality [...]

The impact of the “4d-Rheoprinting” additive manufacturing technique on molecular orientation and thermal properties of polymeric parts

Duhduh A., Coulter J.P., Lehigh University, US

This paper discusses a novel additive manufacturing technique that was developed in order to 3D print polymeric parts with tunable properties. This technique, known as 4D-Rheoprinting, can be applied to a number of common additive [...]

High power electron gun for metal additive manufacturing based on superconducting technology

Thangaraj J., Fermi National Accelerator Laboratory, US

E-beam additive manufacturing is a rapidly growing industry. Electron guns capable of reaching higher energies and higher average power can enable larger melt pools, higher production speed, and permit broader range of materials for metal [...]

Robotic Deposition to Enable Multi-Axis Material Extrusion

Kubalak J.R., Williams C.B., Virginia Tech, US

The material extrusion (ME) additive manufacturing process is extensively used in hobbyist and prototyping applications, but it is not always suitable for the fabrication of end-use components. The thermal characteristics of the layer-by-layer deposition results [...]

Low transmission loss flexible substrates using low Dk/Df polyimide adhesives

Tasaki T., Arakawa Chemical Industries, Ltd., JP

To meet the ever-increasing requirements of transmission data with a growth in the market for information technology gadgets such as mobile phones, the transmission frequency of circuits is increased. However, the integrity of high-frequency signals [...]

XTPL Approach to Print Submicron Conductive Lines on Dielectric Substrates

Kowalczewski P., Wiatrowska A., Dusza M., Zięba M., Cichoń P., Fijak K., Granek F., XTPL SA, PL

The concepts of printed electronics offer a tremendous potential when brought to nanotechnology. We present a novel technology for printing submicron conductive lines at unprecedented flexibility, accuracy, and low cost. The lines with resistivity down [...]

A Stretching/Bending-Insensitive Flexible Pressure Sensor with Carbon Nanotube-PDMS

Zhang R., Stevens Institute of Technology, US

Flexible pressure sensors have many successful applications in personal electronic devices, artificially intelligence, and industrial production applications [1]. Despite the good performance and high flexibility, the measurement of pressure under dynamic deformation has remained difficult [...]

Self-assembly via a quantum control tracking system

Kohn W., Zabinsky Z., Nerode A., Veritone, US

A nano-manufacturing facility requires high levels of precision due to the strong quantum effects for devices at a 2 to 4 nanometer footprint. We develop a feedback process control to realize a 3-D scaffolding approach. [...]
