Velocity painting

[wfcook]

Over in the Google+ 3D Printing group, a guy named Mark Whedon has been experimenting with something he calls Velocity Printing, which basically entails creating images on the surface of a print by varying the print velocity. The vase below is clear PLA with the speeds set to 35 mm/s and 15mm/s. It's very cool and I'd love to have something similar incorporated into Simplify3d... a long shot I know but seriously, this is cool.

+1 It has been suggested that this can be done using Modifier Meshes which is another requested feature.

I'm wondering if this could be done in a similar way to how dual-extruder is done... 2 models, 2 different processes, only using the same toolhead.

No, because the advantage of this technique is that it works without lifting the print head. I believe that with separate processes they are printed in their entirety in a sequential manner.

The code is available online, could be added as a feature, a bit like making pictures 3D. I don't think it modifies the mesh, because the code processes directly the Gcode, not the STL. So it could be "visible" in the Gcode viewer part.

Either way, I would simply LOVE to see that!

Interesting. Count me in for a vote

Do most materials actually change color this much when printed at different speeds? I was looking at a few parts that I printed with different speed settings, and the color looked pretty similar between the two..

I actually disagree that this is a feature the S3D team should spend time on. By all means, it is a cool technique, but I think it is better that they concentrate on the core slicer features and the many high-priority feature requests that needs to be implemented.

Hello
I'm helping out Mark to get his process more accessible to everyone (not all of us can install Perl, dependencies and use a terminal...). I've just built a small UI, packaged into an app for mac and hopefully soon into an exe. If some of you, mac owners, want to give it a try, feel free to ask me here
