3D Printing of Polymers with Hierarchical Continuous Porosity

Dominique Pioletti, Pierre-Etienne Bourban, Matteo Gregorio Modesto Marascio, Jens Antons

Cellular thermoplastic structures with multiscale porosity (1–300 µm microporosity to 0.3–10 mm macroporosity) are produced from an integrated approach of 3D printing by Fused Deposition Modeling printing and Supercritical CO2 Foaming. Porous strands and r ...

DOD Inkjet printing of functional polymers

Jürgen Brugger, Thomas Maeder, Mohammadmahdi Kiaee

Inkjet printing techniques have gained a lot of attention for the micro-structuring of functional materials. This is due to their low cost, low material consumption and relatively easy fabrication process. In this project, Drop-on-Demand (DOD) inkjet print ...

3D-Printed Beam Splitter for Polar Neutral Molecules

Andreas Osterwalder, Sean Dennis Steven Gordon

We describe a macroscopic beam splitter for polar neutral molecules. A complex electrode structure is required for the beam splitter which would be very difficult to produce with traditional manufacturing methods. Instead, we make use of a nascent manufact ...

Dielectric Transduction of NEMS

Kaitlin Marie Howell

We report on a four-mask process flow for creating resonant NanoElectroMechanical Systems (NEMS) based on dielectric transduction. Current transduction mechanisms for NEMS include piezoelectricity, flexoelectricity and dielectric force. While piezoelectric ...
