This paper investigates the technological and economic potential of 10 different AM materials manufactured with four different AM technologies for the use of tools for injection moulding. Therefore, experimental trials with three different injection moulding materials with increasing manufacturing difficulty in terms of resulting tool loads are conducted. Tool wear, resulting part quality and tool manufacturing cost are taken into account for potential evaluation. A concrete selection of the most suitable materials for further investigation is given.

Taiwan has suffered from debris flow disaster in the past decade. Potential debris flow has increased from 485 streams in 1991, to as high as 1719 streams now. These natural disasters affected villages and the safety of Taiwanese residents. As a result, it is necessary to look into more debris flow relevant researches and analytical work.This paper is investigating debris flow streams and analyzing the characteristic of particle river bed. Through the use of fractal theory, we are able to figure out debris flow stream's fractal quantized value.

Postprocessor converting the tool path into numerical control (NC) program is the key technology of NC programming and also an important medium between CAD/CAM system and machine tool. The purpose of this study is to analyze the tool path file NC Intermediate (NCI) produced by the commercial software Mastercam, including the data of the tip point, contact point, contact point vector and other related information. A window-based conversion interface written by Visual C # was developed to transform the NCI file to the required multi-axis NC program and a process operation sheet for the table/spindle-tilting type of five-axis machine tool configuration. It confirms the feasibility of the proposed scheme through verification using the solid cutting simulation software VERICUT® and trial-cut experiment.

An optical add/drop multiplexer, based on asymmetric Bragg couplers with liquid crystal filled in a core of the waveguides, is fabricated. The asymmetric Bragg couplers (ABCs) are fabricated by employing micro-electro-mechanical systems (MEMSs) technologies and holographic interference lithography. In one of the core trench, the liquid crystal is dripped to increase the average effective refractive index of the waveguide. The experimental results show the device is feasible in dense wavelength division multiplexing (DWDM) systems.

This study conducted simulation analysis and experiments on novel piezoelectric acoustic wave components, using finite element analysis software to explore the dispersion relation of piezoelectric components with various periodic structures, shapes, and thicknesses. A microelectromechanical system was employed to etch micropatterns onto films. This study developed four different piezoelectric structures, namely flat, periodic, and single-and dual-defect structures, and measured the frequency response variations in radio frequency and phase signals. The acoustic wave responses of a graphene-like structure with defect distribution were analyzed to develop, design, and fabricate a novel oscillator component. In addition to exploring the bandgap effect in the graphene-like structure model, this study also developed a frequency sweep model for the design of novel oscillating components.

This paper presents a parametric study of a dip-drawing process for making high aspect-ratio polymeric microneedles. The process involves dip-pad spin coating, mold based dip-drawing, UV-curing, necking-break, and final curing. To gain more insight into the process, we characterize the dip-drawing speed and curing time to determine the critical parameters for the microneedle geometry control. The experiment results show that the diameters of the microneedle tips are gradually decreased to 1.69 $mu$m with increasing of drawing speed.

We proposed a new method based on illuminating picosecond laser source through a sub-wavelength annular aperture (SAA) on metallic film so as to produce Bessel-like beam of sub-wavelength spot size while maintaining large depth of focus. To further advance the ease of use in our proposed design, producing sub-wavelength annular aperture with sub-wavelength focusing ability is detailed. It is shown that this method can be applied in the LED sapphire subtract machining with an emphasis to produce high aspect ratio structure (1:5) for laser sawing. More specifically, the ablation property of picosecond laser (1030nm) was utilized to eliminate the laser melting induced residue deposition problem associated with the traditional laser machining. Throughout the research, we have the parameters associated with the optimized SAA structure for 1030 nm wavelength of the picosecond laser obtained by the finite difference time domain (FDTD) simulations method. A lateral microscope system modified from traditional microscope was developed to facilitate the optical energy distribution of the emitted light beam to be used for machining. Finally, the design of SAA device was successfully integrated with the picosecond laser to perform the intended laser micromachining.
