Wat is Stereolithography?
Stereolithography has many names and some of them 3D layers, 3D printing, solid free-form manufacturing, photo solidification and solid imaging. It is the most common and widely used form of rapid manufacturing and rapid prototyping. Stereolithography manufacturing components and makes it possible to create 3D solid objects from 3D CAD models with high precision and excellent surface finish within a few hours (depends on size and complexity). Machines used for Stereolithography Stereolithography Apparatus called (SLA).

Advantages and disadvantages:
Stereolithography offers a fast and easy way to CAD models into concrete objects. This is very useful when time is money. The restriction referred to above is that the time to produce three-dimensional parts is the size and complexity of the object. The accuracy is very good with 0.004 tolerance of ‘/ inch. The problem is that the weather SLA or machines are too expensive. Photo-curable resin used in Stereolithography can be as high as $ 800 per gallon costs. Since the process of SLA produces smoke because it requires a well-ventilated place

Best part of the Rapid Prototyping:
Since 1986, the year of his invention, the SLA has made significant progress in machine design and also the resources used. SLA models and is very fast, fast transition from rapid prototyping to rapid manufacturing. It can be a very useful and valuable process in many cases and for many industries. It is effectively used to facilitate surgeons implant in one ear and can be used in virtually all sectors in the manufacture of jewelry with military force, navy, etc. This makes it the best part of the rapid prototyping.
