Methodology Of Rapid Prototyping
There are a number of different basic methodologies that can be used for current Rapid prototyping techniques. The most basic model is a CAD model which is later constructed into an STL format. The STL format is the industry standard which is accepted by most of the companies that offer rapid prototyping services.
When constructing a CAD model the resolution can be set according to custom standards for the purpose of minimizing stair stepping. This is the most popular methodology used by the vast majority of service providers such as Zoomrp.com.
Another popularly used methodology is the RP machine process. Using these machines the STL files can be sliced into thing layers of the actual model. This is also a highly effective rapid prototyping technique.
In another methodology the first layer of the physical model is actually created. Then this model is lowered with regards to the thickness of the next layer in line. The process is repeated over and over again until the entire model is completed. The model along with any of its supports is removed and the surface of the model is given a nice cleaning and a proper finish.
It is however advised that you ensure which methodology your service provider makes use of so that you can provide them with the accurate data regarding your prototyping plastics. Most rapid prototyping companies will clearly state the desired format on their website along with the maximum file size that you should upload. It is important to follow these guidelines if you want your finished product within your deadline.
