Hi James;

Great post!

I have been pursuing this "holy grail" for prepping circuit boards directly from CAD to etch without intervening steps, off and on for several years now without good success. And these guys pulled it off. Good for them!

In fact it was exactly this application that was my interest in the "community milling machine" project. Of course milling (drilling holes) was only one of the applications; precision motion of a print head was another.

My biggest difficulty was locating a suitable source for inks that would withstand the chemical etching process, and I had migrated to the technology of "wax" printers.

This revelation by these chaps now may revitalize my interest the in the ink process.

Thanks for sharing!

Cheers,

Peter (pjv)
