I’m currently working on an article for my employee’s internal employer magazine about 3d printing. In order to illustrate how FFF/FDM works and how it influences printability, I’d like to use an illustration showing both the layer/filament depositioning approach auf FFF in general as well as why certain model properties such as overhangs might pose a problem. Before I start to make something like that myself: Do you know of any such an illustration that’s free to use (with attribution)? All I can find is the ubiquitious very basic approach posted in the Wikipedia article on FDM.

Thanks for any hints in advance!

I must be slow today. What’s FFF and FDM?

Fused Filament Fabrication / Fused Deposition Modelling

I just added overhang angles to my OpenSCAD layer illustration script and posted it on github: https://github.com/whosawhatsis/layer-illustration
