Introduction to STL Files and 3D Printing

Before we dive into the best STL file viewers for Mac, it's important to understand what STL files are and their role in the world of 3D printing. STL, or Stereolithography, is a file format used for 3D models. It represents objects as a mesh of polygons, allowing them to be easily imported into 3D printers.

The Importance of STL File Viewers

STL files often come from CAD (ComputerAided Design) software, which isn't always userfriendly for nonprofessionals. This is where STL file viewers come in. They allow you to visualize and manipulate these complex 3D models without needing to understand the intricacies of CAD programs.
