The physics of 3D printing with light

Christophe Moser

The goal of 3D printing is to realize complex 3D structures by locally adding material in small volume elements called voxels - in contrast to successively subtracting material by etching, milling or machining. This field started with optics-based proposal ...

Berlin2023

Inkjet printing technology was employed for the application of protective layer coatings in SOFC metallic interconnects. Aqueous-based spinel coatings were inkjet-printed on standard and surface nitrided K41 ferritic stainless-steel substrates. Inkjet-prin ...

Fabrication of zipping electrostatic actuators incorporating inkjet-printed layers

Herbert Shea, Samuel Rosset, Giulio Grasso

Zipping electrostatic actuators operate by bending flexible electrodes using electrostatic forces. This principle allows the use of a wide range of dielectric and conductive materials. Additive Manufacturing (AM) techniques can be used to fabricate these a ...

Assembling Ni-Fe Layered Double Hydroxide 2D Thin Films for Oxygen Evolution Electrodes

Hubert Girault, Andreas Stephan Lesch, Victor Costa Bassetto, Massimo Rosa

Continuous hydrothermal flow synthesis (CHFS) of Ni-Fe layered double hydroxide (LDH) leads to waterborne dispersions of 2D nanoplatelets in the range of 10-50 nm in lateral size. Conversion of the as-synthesized LDH nanoplatelet dispersion into inkjet pri ...

All-printed low-power metal oxide gas sensors on polymeric substrates

Danick Briand, Saleem Khan

This paper presents a novel approach for the fabrication of miniaturized and fully printed metal-oxide (MOX) gas sensors on a polyimide (PI) substrate by using digital manufacturing of the functional layers, namely aerosol jet and inkjet printing technolog ...

IOP PUBLISHING LTD2019

Print-light-synthesis is a new concept for the large-scale in situ fabrication of nanoparticles and structures on large substrates. Here, Pt nanoparticles are synthesized on indium tin oxide (ITO) coated glass slides by using combined inkjet printing and p ...

Rapid inkjet printing of high catalytic activity Co3O4 /N-rGO layers for oxygen reduction reaction

Hubert Girault, Emad Oveisi, Andreas Stephan Lesch, Véronique Amstutz, Victor Costa Bassetto

The accurate and reproducible large-scale production of catalyst layers containing low-cost, abundant electrocatalysts gains in importance. Herein, pivotal factors are discussed that need to be considered when a combined inkjet printing and photonic curing ...

Inkjet printing of carbon black electrodes for dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Samuel Schlatter

Inkjet printing is an appealing technique to print electrodes for Dielectric Elastomer Actuators (DEAs). Here we present the preparation and ink-jet printing of a carbon black electrode mixture and characterise its properties. Carbon black has been used ex ...
