Summary: Direct-write printing has been instrumental in additive manufacturing, especially in extrusion-based printing, expanding the range of materials and applications. However, the synthesis and preparation of printing inks for direct-write printing can be complex. This study develops a precise 3D printable polymer that allows for the easy prototyping of micrometre-scale silicone structures without the need for cleanroom facilities.

Summary: This paper presents an innovative and low-cost method for rapid prototyping of microfluidic chips. The technique involves controlled deposition of aqueous microdroplets on a cooled surface to create printed ice microstructures, which are then coated with a UV-curable acrylic cover layer. The technology is applied to create a microfluidic chip for cell-customized optical-cell analysis, and the chip design is optimized for different cell types. The authors demonstrate the feasibility of using this chip for physiological analysis of different cell types.

Summary: This article presents a rapid prototyping method for sub-megahertz single-element piezoelectric transducers using 3D-printed components. The method involves using 3D-printed external housing parts with a single matching layer and either air backing or epoxy-composite backing. The prototyping time is significantly reduced compared to conventional methods, and the method is demonstrated for 590kHz single-element transducers with temporal pulse controllability and different backing designs.

Summary: Nowadays, there is a wide range of methods being developed in the technology field of selective metallization of polymer surface for manufacturing compact electronic devices. However, most of these methods are expensive, complex, and involve toxic products. In this study, a new process called Rapid 3D-Plastronics was developed by combining 3D printing and selective metallization, offering a low-cost and less hazardous alternative. The process was successfully applied to manufacture complex 3D electronic devices, such as heaters and sensors, high-performance coils, and flexible electronic circuits.

Summary: For the first time, low force stereolithography is used to fabricate chemiluminescence flow-through cells, which outperform those produced through milling, blowing, or alternative 3D printing methods. Different cross-section geometries and customized gaskets and reactors are critically evaluated to enhance the analytical performance of the cells. A five-side polygon cell with Y-type confluence is found to be the most efficient in terms of reagent mixing and photon capture.

Summary: This paper describes a novel method of using a multi-material 5-axis 3D printer to extrude conductive PLA in curved layers. The changes in resistivity of printed traces for different angles and curvatures are characterized. Results show that conformal 3D printing can significantly reduce the resistivity of vertical conductive traces. The paper concludes by successfully fabricating complex conductive patterns onto free-form doubly curved substrates.
