An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...

Development of a Multi-Material Stereolithography 3D Printing Device
Additive manufacturing, or nowadays more popularly entitled as 3D printing, enables a fast realization of polymer, metal, ceramic or composite devices, which often cannot be fabricated with conventional methods.

Additively manufacturable micro-mechanical logic gates. [PDF]
Early examples of computers were almost exclusively based on mechanical devices. Although electronic computers became dominant in the past 60 years, recent advancements in three-dimensional micro-additive manufacturing technology provide new fabrication ...

Wavelength‐Dependent 3D Printing: Introducing 3D Printed Action Plots
Photochemical action plots – wavelength‐dependent reactivity studies of photoactive molecules – can show a significant mismatch between the peak of photochemical action and maximum absorbance in photopolymerization systems in solution. How this knowledge translates to photocuring in light‐driven 3D printing remains unexplored.

Automatic CAD-model Repair: Shell-Closure [PDF]
Shell-closure is critical to the repair of CAD-models described in the .STL file-format, the de facto solid freeform fabrication industry-standard. Polyhedral CAD-models that do not exhibit shell-closure, i.e.

Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo
Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.

Systems Issues in Solid Freeform Fabrication [PDF]
This paper is concerned with the systems aspects of the Solid Freeform Fabrication (SFF) technology, i.e., the issues that deal with getting an external geometric CAD model to automatically control the physical layering fabrication process as directly as

3D Printed Multimaterial Microfluidic Transistors
We introduce a biocompatible, high resolution photopolymer resin that closely mimics the Young's Modulus (elasticity) and reversible stretchability (no hysteresis) of poly(dimethylsiloxane) (PDMS), enabling the fabrication of microfluidic transistors (i.e., microvalves capable of proportional amplification) by multimaterial stereolithography (mSLA ...

Taking Lithography to the Third Dimension
Stereolithography is a new technology which allows the rapid building of plastic models directly from CAD data. The photopolymers needed for this process are developed at Ciba's research center in Marly by a project team from the Polymers ...
