Even though the STL format is around for about 30 years, it is still the single most important format for 3D printing. An STL (Standard Tessellation Language) serves as an interface between the design file (CAD) and the 3D printer. In this article, we explain the technology behind the file format, what programs to use to open the files and possible alternatives of the STL format.
3D modeling is a lot of fun, however, it takes quite some skills to master it. If you are short of time or lack the experience in creating your own 3D printable file, you can check 3D printing databases for existing models. There are plenty of databases for 3D printable models out there, in this article, we introduce you to the most important ones.
There are plenty of file formats for 3D models. A lot of them are native to a specific software (e.g. a CAD program) and cannot be used for any other program. However, there are a few formats, which can be used for the most common 3D programs, as well as for 3D printing. In this article, you will find an overview of popular 3D formats, their applications and the importance for 3D printing.
