3D printing has now been recognized as a very practical technique to create 3D structures with milli-/micron-scale resolution. In tissue engineering, particularly, people utilize 3D printing technique to integrate biodegradable polymers to tissue scaffolds. Hydrogel is highly potential material that provides aqua environment and enables nutrition and oxygen transportation, all of which are requ...

DECprint Printing Services software controls a variety of printer features for a wide range of printers. It supports several different page description languages, handles multiple media simultaneously, and uses different I/O interconnections and communication protocols. Operating within the VMS printing environment, it implements a large number of user-specified options to the PRINT command. DE...

This paper examines the effects of the dramatic changes incurred in the sector of printing and publishing after the introduction of digital printing. The print production process is rapidly shifting from analogue to digital technologies as the infrastructure (or basis) for workflows. The efficiency of the production process requires the digitalisation of all steps and elimination of analogue me...

A unique live-cell printing technique, termed "Block-Cell-Printing" (BloC-Printing), allows for convenient, precise, multiplexed, and high-throughput printing of functional single-cell arrays. Adapted from woodblock printing techniques, the approach employs microfluidic arrays of hook-shaped traps to hold cells at designated positions and directly transfer the anchored cells onto various substr...

The focus of this paper is the analysis of circular cylinders through sets of points in three dimensions. This investigation has a number of motivations. Clearly, if a cylinder of radius R and direction t passes through a set of points P , it means also that there is a line of direction t tangent to the sphere of radius R and centered at the points of P . Another interpretation is that an obser...

Nowadays, functionally graded materials (FGM) are widely used in many industrial, aerospace and military fields. On the other hand, the interest in the use of shrink-fitted assemblies is increasing for designing composite tubes, high-pressure vessels, rectors and tanks. Although extensive researches exist on thick-walled cylindrical shells, not many researches have been done on shrink-fitted th...

In this paper, the effects of carbon nanotube (CNT) orientation and aggregation on the static behavior of functionally graded nanocomposite cylinders reinforced by CNTs are investigated based on a mesh-free method. The used nanocomposites are made of the straight CNTs that are embedded in an isotropic polymer as matrix. The straight CNTs are oriented, randomly or aligned or local aggregated int...

We compare the maximum read range of passive ultra high frequency (UHF) radio frequency identification (RFID) tags that have been produced using different metal printing techniques, specifically inkjet printing and thermal transfer printing. We used the same substrate (THERMLfilm), antenna designs, and electronic circuitry in our comparison so as to isolate the effect of the metal printing. Due...

Objective Three-dimensional (3D)-printing technology is being employed in a variety of medical and surgical specialties to improve patient care and advance resident physician training. As the costs of implementing 3D printing have declined, the use of this technology has expanded, especially within surgical specialties. This article explores the types of 3D printing available, highlights the be...
