PrusaSlicer is great and looks amazing too. It's a bit of a shame that we can't export the layer view as a video! Perhaps the user can select either custom movement that they do via mouse which gets recorded or use some pre-made options. Ex. Rotate camera view 360 around Z axis, around Y axis, around X axis, add/remove layer by layer from top/down or down/top each layer, rotate around Z axis then goto isometric view, etc.

The Prusa print bed should 'Always' be included A) it looks great and B) simple marketing reasons. The output videos could be sent to friends, family, customers who receive parts which can make for a very nice value add as a gift. ie "Here I made this for you and I sent you the link of how it was made too!" Maybe even a generated layer by layer construction showing some form of a nozzle depositing the filament too.

For all of the non 3d printer owners seeing how each layer is constructed, the various colors describing the layers, and etc is very cool to see. 

Not to mention the whole idea further promotes the 3d printing movement.

Just a thought,

While not as easy (for the user) as your suggestion, in PrusaSlicer 2.1 there is an export option to save the toolpath as an obj file. I suppose one could then load that into a 3D animation package (like Blender?) and make your own animation. I'm not sure how to go about removing layers for a rendered printing animation. Perhaps someone with actual animation skills and experience can comment.

For reference, here is an obj file of my Silica Funnel sliced at 0.2mm as exported from PrusaSlicer 2.1 and then zipped for forum upload (and size reduction, the obj file is 84.2Mb): SilicaFunnel

It's a very specific use case and you actually would need an animation software for that. Because once you start offering such a feature you would also want to have options for zoom/angles/lightning/camera roll/speed ...

I agree but all this is a work in perpetual progress, it'd be cool as hell to see/watch, and the output videos would be awesome free advertising for Prusa. 

While lighting, camera angles, and etc would be the icing on the cake I think exporting bmps or jpegs of the current layer window frame should be easy as those images are already created for visual inspection now. So just something that strung those images together to output an mpeg or etc may be all that's needed at the moment. Instead of camera angles really just hiding the mouse pointer and capturing that window as the user changes the view is more than enough. Lighting does get into much more intricate options but honestly I think that'd be overkill and getting more in to the rendering world than it needs to be. 

I just know that anyone I've made parts for who doesn't have a printer gasps when I show them the layer view and explain how it all works. As for the advertising this i3 MK3 w/textured bed is my first printer and after showing a few parts to friends who have multiple printers each they all have said 'that is a great looking part' and then asked how I did x, y, z. My response has always been I designed the part, sliced it, and printed it. They then go on to tell me all the bed sticking/glue issues they have, bed leveling issues, artifact troubles, and etc. So many things I've not come across with this printer are evidently consistent pains in the ass for other printers. Other than a broken wire to the print fan after two weeks of use I've had zero issues with all those things my friends mention. (Prusa does need to increase wire gauge size for that fan though.) So free advertising, more money to development, and etc can only help.

Minor clarification if these forums are being monitored. After having the time to tear into the print head and wiring it was not a pinched/cut fan wire but the fan motor its self. I can measure the PWM leaving the PCB but the fan just has such little torque that it can't get up to speed on it's own. I had a spare fan from a previous project, 12vdc, and the PCB drove it fine even with its 5vdc output. So it's the fan motor.
