What Is Rapid Prototyping?

Rapid prototyping is a technology that takes a three-dimensional computer model and builds a three-dimensional part by building layers upon layers of material. Its speed and low cost allow design teams to confirm their new designs early and frequently in the process.

Step 1

Start with a 3-dimensional computer model. Typically, they are created in 3D CAD products like Solid Works, Rhino, Pro/E, Mechanical Desktop, etc.

Step 2

An STL file is exported from 3D CAD. Typically done as a “File Save As…”. Xpress3D CAD Add-ins perform this step automatically.

Step 3

The STL file is then translated into hundreds (or even thousands) of cross-sectional data points.

Step 4

Starting with the bottom slice, the prototyping machine builds each slice upon the previous, until all the slices are built and the prototype is complete.

Step 5

Final Prototype.
