Abstract: A 3-D printed device comprising one or more structures, the structures comprising a plurality of magnetically responsive particles and one or more diblock or triblock copolymers; the diblock or triblock copolymers having an A-B, A-B-A, or A-B-C block-type structure in which the A-blocks and C-blocks are an aromatic-based polymer or an acrylate-based polymer and the B-blocks are an aliphatic-based polymer. These 3-D printed devices may be formed using a method that comprises providing a magnetic ink composition; applying the magnetic ink composition to a substrate in a 3-D solvent cast printing process to form one or more structures; and drying the one or more structures formed from the magnetic ink composition. The dried structures can exhibit one or more regions of magnetic permeability greater than 1.3×10−6 H/m.

Abstract: A method of acoustophoretic printing comprises generating an acoustic field at a first end of an acoustic chamber fully or partially enclosed by sound-reflecting walls. The acoustic field interacts with the sound-reflecting walls and travels through the acoustic chamber. The acoustic field is enhanced in a chamber outlet at a second end of the acoustic chamber. An ink is delivered into a nozzle positioned within the acoustic chamber. The nozzle has a nozzle opening projecting into the chamber outlet. The ink travels through the nozzle and is exposed to the enhanced acoustic field at the nozzle opening, and a predetermined volume of the ink is ejected from the nozzle opening and out of the acoustic chamber.

Abstract: A printed stretchable strain sensor comprises a seamless elastomeric body and a strain-sensitive conductive structure embedded in the seamless elastomeric body. The strain-sensitive conductive structure comprises one or more conductive filaments arranged in a continuous pattern. A method of printing a stretchable strain sensor comprises depositing one or more conductive filaments in a predetermined continuous pattern into or onto a support matrix. After the depositing, the support matrix is cured to embed a strain-sensitive conductive structure in a seamless elastomeric body.

Abstract: A foam ink composition for printing porous structures comprises stabilizing particles and gas bubbles dispersed in a solvent. The stabilizing particles comprise a predetermined interfacial energy so as to exhibit a contact angle with the solvent of from about 15° to about 90° . At least a portion of the stabilizing particles are positioned at interfacial regions between the solvent and the gas bubbles, thereby stabilizing the gas bubbles in the foam ink composition. A 3D printed hierarchical porous structure comprises one or more continuous filaments arranged in a predetermined pattern on a substrate, the one or more continuous filaments comprising a sintered material and including a porosity of at least about 40 vol. %.
