ABSTRACT In this article, we report the first continuous fabrication of inkjet‐printed polyimide films, which were used as insulating layers for production capacitors. The ink was prepared from its precursor poly(amic) acid, and directly printed on to a hot substrate (at around 160 °C) initialize rapid thermal imidization. By carefully adjusting temperature, droplet spacing, velocity, other printing parameters, films with good surface morphologies between two conducting fabricate work,...
Inkjet printing offers a facile route for manufacturing the next generation of electronic devices, by combining design freedom additive technologies with tuneable properties functional materials and opportunities their integration into heterostructures.

In review, we summarise current developments in ink formulation strategies, approaches tailoring inks, multi-material processing. Material – process property...
Abstract This study reports the successful fabrication of complex 3D metal nanoparticle–polymer nanocomposites using two‐photon polymerization (2PP). Three complementary strategies are detailed: in situ formation nanoparticles (MeNPs) through a single‐step photoreduction process, integration pre‐formed MeNPs into 2PP resin, and site‐selective decoration structures. In strategy, phase‐transfer method is applied to transfer silver copper ions from an aqueous phase toluene solvent disperse them...

Shape-morphing structures possess the ability to change their shapes from one state another, and therefore, offer great potential for a broad range of applications. A typical paradigm morphing is transforming an initial two-dimensional (2D) flat configuration into three-dimensional (3D) target structure. One popular fabrication method these involves programming cuts in specific locations thin sheet material (i.e. kirigami), forming desired 3D shape upon application external mechanical load....
Single-nozzle based multimaterial direct ink writing enables voxel-based fabrication with superior printing efficiency than multi-nozzle protocol. This is attractive for food 3D process where matters its application. However, single-nozzle process, the presence of residual material in shared channel can affect fidelity. In this study, we propose a path planning algorithm that address issue by incorporating (i) advance distance to compensate extrusion delay when switching materials, and (ii)...

Like many pixel-based additive manufacturing (AM) techniques, digital light processing (DLP) based vat photopolymerization faces the challenge that square pixel strategy can lead to zigzag edges especially when feature sizes come close single-pixel levels. Introducing greyscale pixels has been a smoothen such edges, but it is challenging task understand which of permutations projected would give optimal 3D printing performance. To address this challenge, novel data acquisition on machine...
