Blogs

This is a guide to help indiviuals export stl files from various CAD software. It lists step by step ways to export 3D Print ready files from CAD software such as Solidworks, Solid Edge, Blender , AutoCAD, and Rhino, just to name few. Following the steps below will guide you on how to save a file in stl format from CAD software.

We try to keep it as up to date as possible but if you notice that there is a software missing or that some of the instructions are out of date, please let us know. Being relevant and up to date is important to us.

General guidelines for exporting .stl from CAD software

Some software may ask for inputs from users during the export process. Below are some recommendations. Before sending any files to print, it is STRONGLY recommended to use a free .stl viewing software such as mini magics™ to verify .stl files.
When choosing between ASCII and Binary, the latter is generally preferred as it will produce a smaller files size. A low Standard Deviation (SD) will produce a higher resolution and larger file than will a higher SD as will angle tolerance. However, having a low angle tolerance may alter some of the smaller features of a file. We suggest playing around with the variables of the software until satisfied with the results. Typically, files larger than 10MB are unnecessary and cumbersome to upload and work with.
