Stereolithography and photo polymerisation Essay

Stereolithography and photo polymerization - Essay ExampleSome of the advantages associated with Stereolithography include its low costs, production of durable inclinations, efficiency and its high precision (Brtolo). 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 wherefore scans the light-sensitive resins top mould thus hardening it (Miles, Cillo and Sinn). This builds a new seam which is whence 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 terminal 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, eac h layer is cured at a time. In this process, in that location 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 objects 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 make-up is dedicated to provide in - depth research on the principal of operation of Photopolymerisation.Photo bring forth polymerization, otherwise known as Photopolymerisation involves the absorption of Ultra
