Rapid Prototyping

Rapid Prototyping

1. تعريفها

   • is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data.Construction of the part or assembly is usually done using 3D printing or "additive layer manufacturing" technology.

2. Rapid-prototyping processes can be classified into three major groups:

   • Subtractive: removing material from a workpiece that is larger than the final part
   • Additive, building up a part by adding material incrementally
   • Virtual, using advanced computer-based visualization technologies
