Velocity Painting

Welcome to what I hope will become a useful source of information and ideas for Velocity Painting: 3D printing in style.

What is Velocity Painting?

#VelocityPainting is a technique conceived and developed by Mark Wheadon (follow @MarkWheadon on twitter) that allows you to add patterns to your 3D prints without the need to edit the model, use multiple extruders, or swap filament.

The end result is rather wonderful prints like these.

The technique varies the print speed (not the temperature) of a 3D print to map a pattern or image onto the model. The software post-processes the GCODE output from your slicer to affect changes in the print speed. It has some effect when used with opaque filament but really sings with translucents.

Where can I get the software?

Guillaume Vigneron has developed an application which acts as a front-end for my velocity painting script and makes life easier for Windows and macOS users. The app is available from Guillaume’s download page.

The actual script that does the job of converting your GCODE into velocity painted GCODE is written in perl which, if you have a programming background you may be interested in using – or even developing. That’s all available on Github.

Models to print

Fancy trying velocity painting? Here are some models to print complete with instructions on how to do so. You’ll need either the perl script or the application referenced above.

The Lacy Moorish Vase

A  curvy vase with lace-like Moorish patterns. This spiral vase print stands 20cm high yet uses less than 7m of filament.

Vase with Climbing Rose

A curvaceous asymmetric vase with a climbing rose emblem. This spiral vase print stands 20cm high yet uses less than 8m of filament.
