The STL file specification does not specify any such manifold condition, since it is simply a list of coordinates and vectors.

Ideally, STLs intended for 3D printing should include a well-formed mesh, with 2 faces per edge of every triangle (this is sometimes known as a manifold STL, or one with no gaps). STL files contain three dimensional coordinates organized into sets of three along with a normal vector – each of these sets, or vertices (corners) of the triangle, has an orientation normal to the plane that is described by the triangle’s three points. It is almost certain you have come across an STL file before if you have ever used a 3D printer or designed something for 3D printing – but did you know not all STLs are the same? As a matter of fact, you can design a 3D model that meets your functional requirements, and then create an STL file from that model that will create out-of-spec parts.Īn STL file is simply a series of triangles that (usually) form a mesh that approximates a 3D model’s continuous surfaces. That being said, the 3D print files are available on the Cults download platform.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!Īs the standard file format for taking 3D model files into a slicing program for 3D printing in preparation for actual printing, STL files were originally created to be used with stereolithography 3D printing in the late 1980’s (STL stands for Stereolithography). Even more incredible, you can print a 3D printer with your 3D printer! Of course, all you have to do is add some mechanical parts, motors and electronics. Indeed, you can print elements to improve the cooling or the stability of your printer, but also camera supports or storage for your tools. These 3D printable tools can also be closely linked to your 3D printer. You will find many STL files to store screws, nails or other elements in your workshop, your garage, your lab or your maker space. Indeed, every plastic element related to tools or to the realization of works in one's house can be easily 3D printed.

What could be more obvious than using this incredible tool that is the 3D printer to really print tools! In spite of certain resistance constraints for 3D printed tools, it is possible to make a lot of elements.
