Accuracies and tolerances in 3D printing

With every new generation of machines, additive manufacturing is getting more precise, cheaper and faster. However, tolerance comparable to CNC technologies cannot be achieved yet. In this article, we introduce you to tolerances in 3D printing: what are realistic accuracies and what are the most important factors.

The file format STL and its importance for 3D printing

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.

The best sites to download 3D printable Models

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.
