Pulling back from open source hardware, MakerBot angers some adherents

You likely know MakerBot Industries as the poster child for the new era of 3D-printing. You might not know that, until last week, the company and its CEO, Bre Pettis, were considered shining lights in the open-source hardware movement.

Think of open-source hardware, OSHW, as the physical equivalent of open source software. The Open Source Hardware Association, founded just this past March, offers an extended definition for OSHW. Its Statement of Principles sums things up thusly:

The ability to bioengineer new vasculature is a crucial step toward creating new replacement organs such as livers or kidneys from a patient's own cells.

Bioengineers are already working on creating and assembling single layers of cells that have direct access to nutrients and oxygen -- a process known as "bioprinting." But creating a full-fledged array of new vessels remains a major hurdle. Fluidic pressure coursing through these tiny systems … Read more
