Stereolithography System by Multiple Spots Exposure Using a Short Arc Discharge Lamp.

Stereolithography System Using Multiple Spot Exposure

A new method of making 3-D objects is proposed. A discharge lamp is used as a UV light source, and to make the fabrication time shorter, multiple spots exposure using optical fibers is employed. The light is distributed to some optical fibers. The output side of each fiber is arrayed linearly and the emitted lights are focused on the surface of the photosensitive resin. As the fiber array is ra...

Multiple wavelength illumination in flow cytometry using a single arc lamp and a dispersing element.

The principle of a multiple wavelength illumination method for flow cytometers, based upon a combination of a helium-neon laser and an arc lamp as illumination sources is described. By using a prism, the light from the arc lamp is dispersed and the different colors are imaged at different places on the sample stream. The small angle light scattering from the helium-neon laser light is measured ...

Micro Stereolithography Using A Liquid Crystal Display As Exposure Mask

The automotive industry is of key importance in all European countries, in the USA, and in Japan. In order to fulfill the technical and economic requirements of future cars, a consequent utilization of technological developments is necessary. Of paramount importance are miniaturization technologies for sensors, microelectronics and their integration into microsystems. At the moment, a micro fab...

Structural transformation of graphite by arc-discharge

The formation of novel structures by the passage of an electric current through graphite is described. These structures apparently consist of hollow three-dimensional graphitic shells bounded by curved and faceted planes, typically made up of two graphene layers. The curved structures were frequently decorated with nano-scale carbon particles, or short nanotubes. In some cases, nanotubes were f...
