3D Printing of Double Ka Band Helical Antenna

Lanouette A.-M., Hill J., Dussault P.D., Laurin J.-J., Therriault D., École Polytechnique de Montréal, CA

We present a rapid and low-cost fabrication technique to build a small array of antennas operating in the Ka band (20-30GHz). The designed antenna prototypes have a wire diameter of 0.2mm, a helix diameter of [...]

Dual Helix Dielectrophoretic Cell Separator Fabricated Using the Direct-Write Spindle Deposition Technique

Guérin N., Lévesque M., Therriault D., École Polytechnique de Montréal, CA

Many biomedical procedures necessitating the separation of cells would benefit from the miniaturization of cell separators. This miniaturization effort has led to the development of 2D dielectrophoretic separators. The use of a 3D dielectrophoretic cell [...]

VDK 4000 Direct Write System: A new approach to direct write technology

Theodore M., Fielding J., Royer J., Kalanovic V., Nirilovic J., Sears J., AFRL, US

VDK 4000 is a Flexible Robotic Environment (FRE) direct write system. The idea behind Flexible Robotic Environment (FRE) concept is building a robotic modular system around an application instead of having an application fit within [...]

Photonic Curing of Silver Nanoparticle Based Inks Deposited by M3D

West J., Carter M., Smith S., Sears J., South Dakota School of Mines and Technology, US

Photonic curing is uniquely suited to rapidly sinter printed films in an assembly line or roller environment. Previous work has focused on measuring the resistivity of films sintered using photonic curing and comparing those results [...]

Electrophotographic Direct-Write for Electronics

Wagner C., Patwardhan R., Jang B., Mahinfalah M., North Dakota State University, US

A new direct-write method based on electrophotography has been developed for use in electronics manufacture. In this research a test bed was created for proof of concept. This test bed was successfully used to print [...]

Direct-Write CMOS-Based Laboratory-On-Chip

Ghafar-Zadeh E., Sawan M., Therriault D., École Polytechnique de Montréal, CA

Over the recent years, the identification of genes which influence many diseases has been highly demanded and now, molecular diagnosis is most promising technology to offer fast and early detection of diseases to a maximum [...]

Direct Write Technology as a Tool to Rapidly Prototype Patterns of Biological and Electronic Systems

Ringeisen B.R., Chrisey D.B., Piqué A., Krizman D., Brooks M., Spargo B., Naval Research Laboratory, US

The full potential of modeling and simulations is only realized when it is based on experimental results under varied conditions and systems. A single tool to rapidly prototype electronic and biological circuits would enhance the [...]
