We propose an optimization framework for 3D printing that seeks to save printing time and the support material required to print 3D shapes. Three-dimensional printing technology is rapidly maturing and may revolutionize how we manufacture objects. The total cost of printing, however, is governed by numerous factors which include not only the price of the printer but also the amount of material ...

BACKGROUND Over the last decade, image-guided production of three-dimensional (3D) haptic biomodels, or rapid prototyping (RP), has transformed the way surgeons conduct preoperative planning. In contrast to earlier RP techniques such as stereolithography, 3D printing has introduced fast, affordable office-based manufacturing. We introduce the concept of 4D printing for the first time by introdu...

Fruit nursery paper is a protective technical paper that is used in agriculture to improve the percentage of the fruit that meets quality standards and the fruit’s exterior qualities, such as the smooth surface finish and fruit color. In this work, a more efficient and environmentally friendly method, i.e., the printing method, was proposed in order to minimize environmental pollution, reduce t...

3D tissue printing with adult stem cells is reported. A novel cell-containing multicomponent bioink is used in a two-step 3D printing process to engineer bone and cartilage architectures.

Roll-to-roll (R2R) printing has been pursued as a commercially viable high-throughput technology to manufacture flexible, disposable, and inexpensive printed electronic devices. However, in recent years, pessimism has prevailed because of the barriers faced when attempting to fabricate and integrate thin film transistors (TFTs) using an R2R printing method. In this paper, we report 20 × 20 acti...

The significant improvements observed in the field of bulk-production of printed microchip technologies in the past decade have allowed the fabrication of microchip printing on numerous materials including organic and flexible substrates. Printed sensors and electronics are of significant interest owing to the fast and low-cost fabrication techniques used in their fabrication. The increasing am...

The recent developments in 3D printing also known as “Additive Manufacturing” or AM have revolutionized the modern manufacturing process and the engineering design process. Emerging use of 3D printing technology is prevalent in automotive, manufacturing, aerospace, pharmaceutical industry & healthcare, fashion, retail and sports. In this paper, the author propose to review the recent trends and...

The enzymes immobilization of the is crucially effective factor in biosensor preparation. Metal nanoparticles potentially able to immobilize the enzymes according to unique properties including large surface-to-volume ratio, high surface reaction activity, high catalytic efficiency, and strong adsorption ability. A novel and highly sensitive amperometric glucose biosensor was obtained by using ...

This paper deals with study of color deviation caused due to changing screen angle combinations in process color lithographic offset printing. The printing test chart comprises of conventional and customized angles for process colors.
