One of the main challenges facing the electronics manufacturing industry in solder paste printing for ultra-fine pitch surface mount and flip-chip assembly is the difficulty in achieving consistent paste deposit volumes from pad-to-pad. At the very small aperture geometries required for ultra-fine pitch and flip chip assembly, flow properties of the paste becomes one of the dominant factors in ...

Abstract Acrylonitrile butadiene styrene (ABS) is a multipurpose thermoplastic and the second most popular material in extrusion (MEX) additive manufacturing (AM). It widely used various types of industrial applications automotive sector, housing, food processing, among others. This work investigates effect seven generic control parameters (orientation angle, raster deposition infill density, l...

In recent years the field of large-area, organic and printed electronics has demonstrated various applications of functional devices. For most of the applications, a reliable supply with electric energy tailored with respect to functional devices and applications is a mandatory, making thin-film battery a challenging area of research. Among a variety of manufacturing concepts printing technolog...

Inkjet Printing of MXene/MnO2 Composite Films In article number 2101453, Dong Wen, Guobing Ying, Xiang Wang, and co-workers present an inkjet printing strategy flexible high-performance composite film electrodes for new generation supercapacitive applications. This provides a low-cost, large-area manufacturing route different MXene-based materials, is expected to promote the development utiliza...

Fluid drops tend to be spheres--a shape that minimizes surface energy. In thunderstorm clouds, drops can become unstable and emit thin jets when charged beyond certain limits. The instability of electrified drops in gases and liquids has been widely studied and used in applications including ink-jet printing, electrospinning nanofibers, microfluidics and electrospray ionization. Here we report ...

OBJECTIVES Previously, the author reported a cluster of 11 cholangiocarcinoma cases exposed to 1,2-dichloropropane (1,2-DCP) and/or dichloromethane (DCM) in an offset proof-printing company. Before that report, the association between the two chemicals and cholangiocarcinoma had not been known. The current study describes two cholangiocarcinoma patients exposed to 1,2-DCP or DCM in different of...

Three-dimensional (3D) printing has a long history of applications in biomedical engineering. The development and expansion of traditional biomedical applications are being advanced and enriched by new printing technologies. New biomedical applications such as bioprinting are highly attractive and trendy. This Special Issue aims to provide readers with a glimpse of the recent profile of 3D prin...

Most 3D printing designs are inspired by existing designs. This is specially true for prosthetic designs. Designers try to improvise on previous designs. However, they often fail to credit sources, thus making it difficult to track the design changes. This problem can be solved by finding lineage patterns in the 3D printing design repositories and visualizing them. Thingiverse is an online 3D p...

We present a printer that builds functional three-dimensional structures by reversible assembly of a discrete set of components, “digital materials”. This approach uses the components rather than a control system to impose the spatial and functional constraints. Printing can be performed as a parallel rather than a linear process. The printing process is reversible for re-use of the pieces or f...

We present an interactive CG (Computer Graphics) design system based on virtual woodblock printing, with the stress on an aspect of a tool to enjoy creation in a virtual space. This system is a simulation of real woodblock printing: generating a woodblock, spreading inks on the woodblock, putting a paper sheet on the woodblock, and rubbing the paper sheet with a Japanese squeegee “BAREN” in a v...
