For questions regarding `.stl` files and the STL file format.

From Wikipedia - STL (file format)

STL (an abbreviation of "stereolithography") is a file format native to the stereolithography CAD software created by 3D Systems. STL has several after-the-fact backronyms such as "Standard Triangle Language" and "Standard Tessellation Language". This file format is supported by many other software packages; it is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact.

How can I create PNG image files from STL files?

I need to add some simple image renders of STL files to a document. I currently open the STL files in Preview or one of the slicers and grab a screen shot. Is there an easier or automatic way to generate PNG images from STL files on a Mac?

Export STL as ASCII or binary?

When go to export a model using Fusion 360 or Meshmixer, I see that there are two options. Could the final model be affected by the format chosen at the time of saving?

Outputting an STL file that contains multiple objects for import into Blender

I want to print a object that looks like a flat board with a set of matchbox-like lumps on top of it. I have written a script that outputs an STL file. To keep the script simple, it creates an object that includes non-manifold edges. To be precise,…

Route to transform 2d image (depth map) into a curved bracelet (and STL file)?

I've got a bracelet concept that I've sketched up as a flat design. I'm trying to found a route by which I can extrude this into a 3d object (depth map?), curve it into a bracelet, then ultimately create a STL file out of it. I'm having trouble…

How to stop Fusion 360 from creating a new version on STL export

Everytime I export to STL in Fusion 360, a new Version (V1, V2, V3, V4, ...) of the file is created. But I would really like to use that feature to mark bigger changes instead of creating a new version everytime I change a minor detail to see how…
