An STL file does not contain any information regarding texture, color, or qualities such as flexibility or strength – only the shape and geometry. The more complex the design, the more triangles are used to represent it. In STL files, these designs are represented by triangles – hence “triangle language” or “tessellation language.” Because these triangles share edges, their location can be determined by a computer or slicing program (more on this below) to create a full image that can be 3D printed. These digital files contain geometric information about a design that is meant to be 3D printed.
What is an STL file?Īn STL (for “Standard Triangle Language” or “Standard Tessellation Language”) file is one of the most common file formats for both 3D printing and computer-aided design (CAD). This blog will focus on STL files, their uses, and where to find free repositories of files that you can use on your 3D printer.
On the other hand, you may be wondering how to get started, or you may not have the time to create and design your own files. You may already have an idea of what to print and how to print it – or even be able to design 3D prints yourself. Once you’ve purchased a 3D printer, it’s time to begin printing.
