PURPOSE This study is to evaluate the internal fit of the crown manufactured by CAD/CAM milling method and 3D printing method. MATERIALS AND METHODS The master model was fabricated with stainless steel by using CNC machine and the work model was created from the vinyl-polysiloxane impression. After scanning the working model, the design software is used to design the crown. The saved STL file...

3D Printing technologies have received extensive attention in recent years, but empirical investigations of how this technology is used for manufacturing are still sparse. More knowledge is also needed regarding how 3D Printing will affect the competitive dynamics between firms. This article explores how 3D Printing has been adopted for manufacturing and discusses under what conditions it might...

Benzene is an aromatic hydrocarbon that, with sufficient cumulative lifetime doses, can cause acute myelogenous leukemia. Because of its volatility and solvent properties, it was used in the printing industry in inks, ink solvents, and cleaning agents from the 1930s to the 1970s. This analysis represents the first known attempt to gather and synthesize the available data on historical airborne ...

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...
