The purpose of this study is on the development of 3-D conductive pattern fabrication system
using laser. For development 3-D direct patterning system, we used the dynamic focusing …

The micro fabrication on the mold material using picosecond laser ablation processing has
been studied. We used the two kind of system with picosecond laser. First one is two mirror …

In this paper we report direct laser structuring technology for circuit patterning. The laser
structuring could replace photolithography and additional processes for manufacturing …

There is no established technique for the 3‐dimensional (3‐D) pattern formation, and many
structures cannot be formed using the conventional CAD/CAM technology. We have …

This study evaluated an inexpensive 3D printer (below 1000 USD) as a cost effective laser
direct writing machine. This printer was applied to patterning copper (Cu) electrodes along …

1 Background As the industrial structure becomes globalized, the electronic technology has
become one of the major fields that support the Japanese economy and industry. Several …

A laser head was designed for micro-scale patterning and joining applications. The target
feature size of the pattern was $100 {\mu} m $, and optics were designed to perform the …

Recently, several investigations have been reported on hybrid technology that embeds
circuits on 3D printed models during processing. A new direct fabrication method of …

抄録 Laser forming is a technology that produces plastic deformations in sheet materials by
generating local heat stress. It is useful for prototype or small-quantity production because it …

The deformation of substrate caused by laser scanning pattern during direct laser fabrication
(DLF) is ignored in spite of its importance to the final dimension accuracy. In this paper, in …
