That last section was a bit more geometry than you probably care about - what’s important to this discussion however, is the mesh created by all these triangles.
SMALL 3D PRINT FILES SOFTWARE
A quick online search for your CAD software and “STL export options” will usually point you in the right direction. In general, it’s best to export your STLs from mainstream CAD software with known-good STL export capabilities - pretty much all modern commercial engineering CAD software and the more well-known open source or hobbyist packages fall into this category. STL files, especially ones created directly from 3D scanners, can often contain non-manifold geometry or incomplete surfaces that may be difficult or impossible to 3D print correctly, and may cause errors during slicing. However, an STL file is simply a list of coordinates and vectors and there is no requirement in the STL file specification for such a manifold condition. It’s important to note that STLs intended for 3D printing should contain a well-formed mesh or meshes that fully enclose the geometry that you wish to create, with each triangle edge connected to exactly two faces (this is sometimes known as a manifold STL, or one with no gaps). To be more precise, an STL file contains a list of three dimensional coordinates, grouped into sets of three along with a normal vector - each of these sets of three coordinates makes up the vertices (corner points) of a triangle and the vector is normal, or perpendicular, to the plane which is described by the three points of the triangle. STL files simply describe a set of triangles that (usually) make up a mesh which approximates the continuous surfaces of a 3D model. If you’ve ever used a 3D printer, or designed something to be 3D printed, there’s an almost certainty that you’ve encountered an STL file before - but did you know that not all STLs are equal? In fact, it’s entirely possible to design a 3D model that meets your functional requirements and then generate an STL file from that model that will produce out-of-spec parts. If your model still contains excessive flat spots at these settings, you can try decreasing the values of the chordal and angular tolerance, with the strong recommendation of continuing to keep the file size below 20 MB.Īs the original file type created for stereolithography 3D printing in the late 1980’s (STL comes from STereoLithography), the STL file format is effectively the 3D printing industry standard for importing 3D model files into a slicing program like Markforged’s Eiger software, in preparation for actually 3D printing the model. If the resulting file size is greater than 20 MB, we strongly recommend reducing the file size by increasing the values of the chordal and angular tolerance until the STL file size has been reduced to less than 20 MB, as the large file size can significantly slow down the computations involved in preparing the STL for 3D printing.

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. 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!
