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.
An STL file is exported from 3D CAD. Typically done as a “File Save As…”. Xpress3D CAD Add-ins perform this step automatically.
The STL file is then translated into hundreds (or even thousands) of cross-sectional data points.
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.
