Add Analyzing STL Files page

New page

=Introduction=
Analyzing STL files for "printability" (i.e. problems or defects), or the amount of plastic or filament needed is quite useful.

This page attempts to document solutions to this problem.

=Research=

Analyzing for "printability" or checking for problems or defects seems easier or more common than analyzing for the amount of plastics needed.

This website analyzes for the following "printability":
*'''Model issues:''' This will indicate whether the model has any issues or not.
*'''Non-manifold edges:''' the number of non-manifold edges in the model (highlighted in red inside the editor).
*'''Boundary edges:''' the number of boundary edges in the model (highlighted in magenta inside the editor).
*'''Dimensions:''' the dimensions of the 3D model in centimeters as width, height and depth.
*'''Object information:''' the number of triangles, number of vertices and the volume of the model.

Here's another website I found that offers a similar service, and has a online demo:
*https://www.3dhubs.com/knowledge-base/fixing-most-common-stl-file-errors/

Checks for common STL errors:
* Boundary edges
* Intersecting faces
* Non-manifold edges
* Over-refined mesh {over-refined-mesh}

The also have an '''online printability analyzer''':

Looks like there's only paid solutions, rather than free open-source ones.

I also stumbled across a library called [https://github.com/bmander/skeinforge skeinforge] (used by Rep-Rap [https://reprap.org/wiki/Skeinforge see also]) that converts STL files into G Code which could be useful.
