The inkjet printing has grown into a mature noncontact patterning method in the recent times. With this method, large-area patterns can be easily created with high speeds while using only small amounts of functional materials and also high resolution can be achieved. RFID tags, organic thin-film transistors OTFTs and electrochromic devices ECDs are the major areas employing the method of inkjet printing. The future of plastic electronics is focussed on this technology.
solution processable materials are used to print conductive features onto ....etc

ABSTRACT
Selective laser sintering (SLS) is technique by which parts are building layer by layer. The SLS is a free form fabrication method to create components by precise thermal fusing of powdered materials.
This is durable, economical and fast. The SLS is another form of rapid prototyping. This selective laser sintering (SLS) is one among the rapid prototyping which include stereo lithography (SLA). This method has also been extended to provide direct fabrication of metal and ceramic objects and tools. With this method ....etc

laser cleaning of micro slots and cracks

Abstract
Thermal based laser surface cleaning could strongly depend on the temporal pulse shaping of laser. In this study, we have investigated, based on a Finite Element Method (FEM), the effects of different temporal pulses (Excimer laser, 248 nm, 26 ns), including rectangular and Gaussian shapes, in laser cleaning of microtapered slots covered by oil film (1.0 m thick). The FEM model was verified with an analytical solution for a flat surface, and then applied to the tapered micro-slots structure. P ....etc

pulsed laser micro polishing seminar ppt

Abstract
The objective of this work is to predict the final roughness of metal surfaces that have undergone pulsed laser micro polishing. The motivation for pulsed laser micro polishing is to reduce the surface roughness of parts whose surface texture can approach the feature size. Being able to predict the magnitude of the polishing and frequency (wavelength) content of the surface will assist in the design of optimal processing parameters with minimal experiments. Laser pulses are used to create shall ....etc

Laser Micro-Patterning by Means of Optical Fibers with Micro-grinded Lens End Faces



Introduction

Nano-patterning of polymer surface has found a wide range of applications including biotechnology, where holes in the size of hundreds nm can influence the growth and differentiation of relatively large living cells . Instead of the e-beam patterning technique used in the Ref. 1, we ap-plied direct writing by laser-light. In our previous papers , we have demonstrated that th ....etc
