Exporting for 3D printing

- [Instructor] So, we prepped our model for 3D printing,…and, in this video, we're gonna cover the process…of exporting from Rhino to a format…that a 3D printer can understand.…Right now, our model is all made up of NURBS objects,…and that is not a format that a 3D printer can understand.…We need to convert these into mesh objects and export them,…usually in a format called an STL file.…Unlike NURBS objects, which are infinitely mathematically…smooth, mesh objects are faceted, so they're made up…of individual flat, triangular faces.…

And the challenge with exporting for 3D printing…is preserving as much detail in your model,…preserving all those important design features,…and surface features, while not building in…too much information into the file.…So let's go ahead and take a look…at the mesh export settings.…I'm gonna zoom out here, and just do a crossing selection…to grab all of the objects that we'd like to sense…as our 3D print.…From the File menu, I'll select Exports Selected.…I wanna be careful not to select Export,…
