3D printing and law/policy conference in DC

Michael Weinberg from Public Knowledge sez, "We are bringing the 3D printing community back to Washington, DC for 3D/DC II. This time around, we are having a public reception in the Rayburn House Office Building on April 24th to give policymakers a chance to see 3D printing in person and talk to some of the people behind the machines. If you are in DC and are interested in 3D printing, this could be your chance to check it out." Michael wrote two amazing, definitive papers on 3D printing and the law.
