The motivation for this research is based on how artists mix and print colour by traditional means (painting and printmaking) and how these differ from colour picker tools, slider bars and methods developed for digital printing, and whether it is possible to incorporate both? Artists have been expert at mixing colour for centuries, yet although the artist and designer has access to a wide range...

Printed electronics rely on low-cost, large-area fabrication routes to create flexible or multidimensional electronic, optoelectronic, and biomedical devices. In this paper, we focus on one- (1D), two- (2D), and three-dimensional (3D) printing of conductive metallic inks in the form of flexible, stretchable, and spanning microelectrodes. Direct-write assembly is a 1-to-3D printing technique tha...

In 2013, the first gun printed out of plastic by a 3D-printer was successfully fired in the U.S. This event caused a major media hype about the dangers of being able to print a gun. Law enforcement agencies worldwide were concerned about this development and the potentially huge security implications of these functional plastic guns. As a result, politicians called for a ban of these weapons an...

This article presents an overview on typical properties, technologies, and applications of liquid metal based flexible printed electronics. The core manufacturing material—room-temperature liquid metal, currently mainly represented by gallium and its alloys with the properties of excellent resistivity, enormous bendability, low adhesion, and large surface tension, was focused on in particular. ...

Textile printing systems are needed that will meet the requirements of time-driven, demand activated manufacturing. Electrophotography and ink-jet printing are technologies that have the potential of meeting these requirements. Textile-specific, electrophotographic and ink-jet printing toners/inks must be developed if these technologies are to gain acceptance in the textile industry. The develo...

In this paper, we present an interactive CG creating system with a pressure sensitive pen and a tablet. This system is based on the virtual sculpting and printing method which are simulations of the real sculpting and woodblock printing. In the virtual sculpting process, the user operates virtual chisels with the pen to sculpt a virtual wooden object which has a 3D shape. The user can control t...

Laccase enzyme has been used as a substitute of harmful mordants in fixation of three different types of flavonoids (natural dyes), namely rutin, morin and quercetin, in printing of fabrics and the optimum conditions to achieve the best results are determined. The effects of enzyme concentration, pH of printing paste, treatment time and temperature as well as the nature of the printed substrate...

background: according to the growth of photocopier usage in workplaces, the potential risk of occupational exposure to the airborne chemicals has been raised up. hence, monitoring the photocopy worker's respiratory functions seems to be necessary. we aimed to evaluate the respiratory health on photocopy and printing workers so that a reliable description can be made about their occupational hyg...

Background: Medical 3D printing is expanding exponentially, with tremendous potential yet to be realized in nearly all facets of medicine. Unfortunately, multiple informal subdomain-specific isolated terminological ‘silos’ where disparate terminology is used for similar concepts are also arising as rapidly. It is imperative to formalize the foundational terminology at this early stage to facili...

Micro-contact printing, μCP, is a well-established soft-lithography technique for printing biomolecules. μCP uses stamps made of Poly(dimethylsiloxane), PDMS, made by replicating a microstructured silicon master fabricated by semiconductor manufacturing processes. One of the problems of the μCP is the difficult control of the printing process, which, because of the high compressibility of PDMS,...
