3D-Printed Electrohydrodynamic Pump and Development of Anti-Swelling Organohydrogel for Soft Robotics.

This study introduces advancements in electrohydrodynamic (EHD) pumps and the development of a 3D-printable anti-swelling organohydrogel for soft robotics. Using digital light processing (DLP)technology, precise components with less than 1% size variation are fabricated, enabling a unique manifold pump array. This design achieves an output pressure of 90.

Photocurable Sol-Gel Formulations for the Fabrication of Titanium Carbide/Carbon Nanocomposites via Digital Light Processing.

Additive manufacturing of carbide materials has received significant attention in the past years due to the ability to fabricate complex structures over different length scales. However, the typical limitations for powder-laden inks, such as nozzle clogging, rheological and geometric constraints, particle sedimentation, light-scattering and absorbing phenomena, narrow the range of available processes to manufacture carbide materials via conventional particle-based systems. To address these shortcomings, we have developed a one-pot synthetic route for the preparation of sol-gel-based UV-photocurable formulations, aiming at the fabrication of titanium carbide/carbon nanocomposites using digital light processing printing, pointing to potential applications in the field of nuclear physics.

Tunable Lotus Leaf Effect by Three-Dimensionally Printed Stretchable Objects.

Adjustable wettability is important for various fields, such as droplet manipulation and controlled surface adhesion. Herein, we present high-resolution 3D stretchable structures with tunable superhydrophobicity, fabricated by a stereolithography-based printing process. The printing compositions comprise nonfluorinated monomers based on silicone urethane with dispersed hydrophobic silica particles.

Continuous Material Deposition on Filaments in Fused Deposition Modeling.

A novel approach, i.e., Continuous Material Deposition on Filaments (CMDF), for the incorporation of active materials within 3D-printed structures is presented.

Applications of a vacuum-actuated multi-material hybrid soft gripper: lessons learnt from RoboSoft manipulation challenge.

Soft grippers are garnering increasing attention for their adeptness in conforming to diverse objects, particularly delicate items, without warranting precise force control. This attribute proves especially beneficial in unstructured environments and dynamic tasks such as food handling. Human hands, owing to their elevated dexterity and precise motor control, exhibit the ability to delicately manipulate complex food items, such as small or fragile objects, by dynamically adjusting their grasping configurations.
