The TL DR: Exporting CAD geometry with the right STL resolution will result in 3D printed parts with the highest dimensional accuracy and surface finish, without slowing down the slicing process. STL Export Settings by Major CAD Software Mesh Quality vs File Size: Our Recommendations Angular Tolerance/Angular Deviation/Normal Deviation In the guide we will cover the following aspects of STL files and 3D Printing: We’ve been getting a lot of questions from new users about these types of faceted surface characteristics on their printed parts, so in the interest of helping everyone get the best possible prints from their 3D printer, we’ve put together this guide to creating high quality STLs that will make for great 3D printed parts. Once you’ve set all of these options, click “OK” and then “Save” to export your STL file.Have you ever 3D printed a part that had flat spots or faceted surfaces where smooth curves were supposed to be? Or maybe you’ve just seen a picture of a 3D print that looked like it belonged in some low-resolution CGI from the 90’s? You are not alone, and it’s not your 3D printer’s fault - the culprit is likely a lack of resolution in the STL file that was used to create the part! If you’re not sure what size you want your model to be, we recommend leaving this at the default 100%. Scale: This setting allows you to scale your model up or down. The most common unit of measurement for 3D printers is millimeters, so we recommend selecting that option. Units: This setting determines the units that will be used in your STL file. Lower resolutions will result in smaller files, but they may not be as accurate.

Higher resolutions will result in larger files, but they will be more detailed and accurate. Resolution: This setting determines the level of detail in your STL file. This will open up a new window with some options for how to save your file. To do this, go to File > Save As and select the “3D Model (*.stl)” option from the drop-down menu. Additionally, if the image is not properly prepared for conversion, it may not print correctly. If the 2D image is not of high quality, the STL file will not be accurate.

STL files are 3D models that can be used in 3D printing, and they are often created from 2D images. PRO TIP: STL files can be created in Photoshop, but there are some risks involved.
