Image to Halftone to Printable Object

This is a Processing app that will load a JPEG or PNG, convert it to a halftone image (with many parameters), and output a STL[1] or OpenSCAD[2] file.

Make cool halftone coasters. Use them as plastic "rubber" stamps. Make art!

This app was a result of a question posed on the Makerbot Operators Google group, and was written in 10-12 hours over the course of a few days. Feel free to take it and add features or make a standalone app or whatever.

You can download the source as well as packaged executables for Windows, OSX, and Linux.[3]

DISCLAIMER: This app is presented as-is and does not come with ANY support. (No time for that here, sorry)

NOTE 1 - the resulting STL files MUST be run through a post-processing app like Netfabb to create printable models.

NOTE 2 - the resulting OpenSCAD files can take a REALLY LONG TIME to render in OpenSCAD before you can save a STL from there.

NOTE 3 - I've only tested the OSX executable (which works fine), but not the Windows or Lin
