This is a design from our SIGGRAPH 2016 paper Procedural Voronoi Foams for Additive Manufacturing.
For each of the examples in this collection, we provide the following data:
Raw volume data of the model without the base.
Raw volume data of the model with a planar base.
A ply mesh of the surface without the base.
A ply mesh of the surface with a planar base.
When available, the .tar.gz used to print the model on the Ember.
When available, the .b9j used to print the model on the B9Creator.
The surface mesh are obtained by running marching cube on the volume data. The surface is unfiltered, but you can run a few steps of Laplacian smoothing on it.
The volume data is padded with 0 so that marching cube can be run directly on it. The volume data can be opened directly in Paraview (open the .mhd file). Alternatively, the volume data can be read as a 3D numpy array using this Python script.
When using the .b9j file, you need to reset the file settings from the B9 software. The reason is that the .b9j has been produced directly from the slice images, using an old
retro-engineered version of the file format.
