Download file to see previous pages Some of the advantages associated with Stereolithography include its low costs, production of durable objects, efficiency and its high precision (Bártolo). Basically, the process of building an object using the Stereolithography entails the creation of a 3 – D model of the object using a desired CAD software, using a software such as lightyear in slicing the produced 3 – D model into series of horizontal slices (Thin slices). An ultraviolet sensor then scans the photosensitive resin’s top layer thus hardening it (Miles, Cillo and Sinn). This builds a new layer which is then attached and lowered below the surface covering the distance of one layer. A new layer is then coated on top of the previously scanned layer and the process repeated till the final product is produced.
In the process of printing, a laser is used in drawing the models layers, each at a time, to a photopolymer resins and in the process, each layer is cured at a time. In this process, there is projection of light beam – UV light – in form of a laser on the resin at a specific point and as a result, the parts of the resins reacts and then solidifies. This is then followed by the laser drawing the object’s cross-section resulting in a hardened layer (Newnes).
As seen in the above description of the process of the construction of an object using Stereolithography method, it can be seen that light plays an important role in the solidification of the photosensitive resins. The above description is based on a construction using the laser lithography (Stereolithography) but this can be achieved, also, using other technologies such as the Photo – Mask technology. The creation of objects using these technologies is based on the principle of Photopolymerisation. This section of the paper is dedicated to provide in - depth research on the principal of operation of Photopolymerisation.

Description Of The Photo
...Description Of The Photo Some photographs bring back such memories to mind that make us gloomy for some moments. When we look at such pictures, we go into a flash-back and experience the same pain and sadness that we were going through at the time the picture was taken. Still, we keep such photographs and secure them in albums and photo frames no matter how much they discomfort us whenever we look at them. I have never understood this context of human nature. Why should a man save such items in possession that inflict pain on his heart? Why is it a part of human nature to enjoy suffering? I do not know if I am right, but all I know is that there are some pictures in my possession that make me sad. The...

Photo analysis research paper
...Task: Photo analysis is one of the major components of studies in the faculty of visual arts and films. It involves a detailed description of a photo using various analytical tools such as the lines, photo backgrounds, history, and several others. Analyzing a photo has numerous advantages, both to a society and to students studying the subject. It reveals the history of a given work of art. With this, an individual can easily tell some of the weaknesses of the early or renaissance art. This, in turn, enables students make improvements as well as avoids some of the common errors visible in the photos. Every aspect of study or academic always improves in...

...September 8, Waterfronts in Tokyo and Singapore The photos capturing the waterfronts of Tokyo and Singapore are both magnificent and breath-taking given that the backdrop of the views shows the highly industrialized cities. From the waterfront of Tokyo, viewers’ interest and focus are immediately captured by the replica figure of the Statue of Liberty which is strategically located at the forefront of the body of water. On the other hand, the waterfront of Singapore does not have any other significant landmarks that could divert the attention of viewers. As such, the focus is clearly oriented on the clean, sparkling waters that perfectly magnify and reflect the images that are visually seen: the large brightly lit...

The main tools of a photo are line, form, design, shape, color, depth, lighting and symmetry. The photographer may pay attention to some of these elements depending on what he or she wants to emphasize. The picture does not necessarily need to include all these tools but can include one or two depending on the intentions of the photographer (Bowden 15).

Polymerisation of alkenes
...Polymerisation of alkenes Introduction Crude oil is one crucial natural resource in the developed countries. It is used in the generation of heat, driving of vehicles, machinery, and airplanes. The components of crude oil are used in the manufacture of all chemical products like plastics, paints, detergents, medicines, paints. In our daily life, oil is applicable in almost all sectors. One study showed that at least each year, about 18 million tonnes of crude oil are processed to form some synthetic material (Thompson and Manning, 1995). About 40% of all textiles require oil. In making CDs and DVDs, at least 40 litres of oil is used each year. Oil is important because it helps in relaxing. One single sofa has about 60...
