This paper discusses the design and integration of a desktop system for electrohydrodynamic jet (E-jet) printing. E-jet printing is a micro/nano-manufacturing process that uses an electric field to induce fluid jet printing through micro/nano-scale nozzles. This enables better control and resolution than traditional jet-printing processes. The printing process is predominantly controlled by cha...

With the development of 3D printing technology, 3D printing has recently been applied to many areas of life including healthcare and the automotive industry. Due to the benefit of 3D printing, 3D printing models are often attacked by hackers and distributed without agreement from the original providers. Furthermore, certain special models and anti-weapon models in 3D printing must be protected ...

A novel paper-based biofuel cell with a series/parallel array structure has been fabricated, in which the cell voltage and output power can easily be adjusted as required by printing. The output of the fabricated 4-series/4-parallel biofuel cell reached 0.97±0.02 mW at 1.4 V, which is the highest output power reported to date for a paper-based biofuel cell. This work contributes to the developm...

Over the last two years, the Coors Brewing Company has been conducting a pollution prevention and energy conservation project jointly with the DOE, EPA and Colorado Office of Energy Conservation, utilizing the NICE (National Industrial Competitiveness through Energy, Environment, and Economics) program. The goals of the project are to investigate a can printing technology developed at Coors, an...

Three-dimensional (3D) printing has been particularly widely adopted in medical fields. Application of the 3D printing technique has even been extended to bio-cell printing for 3D tissue/organ development, the creation of scaffolds for tissue engineering, and actual clinical application for various medical parts. Of various medical fields, craniofacial plastic surgery is one of areas that pione...

Color printing proceeds with multiple halftone separations overlay. Because of separation overlay misalignment in printing, the percentage of different primary color combination may vary and it will result in color shift. In traditional printing procedure with AM halftone, every separation has different screening angle to make the superposition pattern in a random style, which will reduce the c...

3D-printing methods are used to generate reactive material architectures. Several geometric parameters are observed to influence the resultant flame propagation velocity, indicating that the architecture can be utilized to control reactivity. Two different architectures, channels and hurdles, are generated, and thin films of thermite are deposited onto the surface. The architecture offers an ad...

Over the past decade, 3D printing technology has been leading manufacturing revolution. A recent development in field of added time as a fourth dimension to obtain 4D parts. fabricated design created by is static, whereas capable altering its shape response environmental factors. The phrase “4D printing” was introduced Tibbits 2013, and since grown popularity. Different smart materials, stimulu...

This paper reports the design, simulation, fabrication, and experimental testing of a low-frequency piezoelectric energy harvester fabricated using screen-printing technology. A centrally supported meandering geometry is chosen to reduce the torsional mode effects during the unit vibrations and to achieve better power efficiency. The design experiences alternating stress along the beams and a s...

This paper proposes and describes an architecture that enables the identification and spreading of green norms in agent societies and the eventual elevation of green norms into policies. Using a real world case study on duplex printing, this paper demonstrates how norms can be identified and also discusses approaches for spreading norms. Using an agent-based simulation study of the energy conse...
