Rapid prototypingRapid prototyping is the most common is the most common name given to a host of related name given to a host of related

technologies that are used to fabricate technologies that are used to fabricate physical objects directly from CAD data physical objects directly from CAD data sources. These methods are unique in sources. These methods are unique in that they add and bond materials in that they add and bond materials in

layers to form objects. Such systems are layers to form objects. Such systems are also known by the names also known by the names

fabricationfabrication (SFF) and (SFF) and layered layered manufacturingmanufacturing. .

Today's additive technologies offer Today's additive technologies offer advantages in many applications compared advantages in many applications compared to classical subtractive fabrication methods to classical subtractive fabrication methods such as milling or turning: such as milling or turning:

Objects can be formed with any geometric Objects can be formed with any geometric complexity or intricacy without the need for complexity or intricacy without the need for elaborate machine setup or final assembly; elaborate machine setup or final assembly;

Rapid prototyping systems reduce the Rapid prototyping systems reduce the construction of complex objects to a construction of complex objects to a manageable, straightforward, and relatively manageable, straightforward, and relatively fast process. fast process.

The Basic ProcessThe Basic ProcessAlthough several rapid prototyping Although several rapid prototyping

techniques exist, all employ the same basic techniques exist, all employ the same basic

five-step process. The steps arefive-step process. The steps are: : Create a CAD model of the design Create a CAD model of the design Convert the CAD model to STL format Convert the CAD model to STL format Slice the STL file into thin cross-sectional Slice the STL file into thin cross-sectional
