TechCrunch (July 24) -- Voxel8, the startup behind the first multi-material 3D electronics printer, has raised $12 million to bring its printers to the desks of engineers and designers everywhere. The result of a decade of patented research by co-founder and Harvard Professor Jennifer Lewis, Voxel8 printers are able to print fully functional electronics by incorporating materials such as conductive inks, flexible silicones and high-strength epoxies. Lewis is the former professor of materials science and engineering and former head of the Materials Science Laboratory at Illinois.
