A federal judge has issued a preliminary injunction blocking two types of 3D printing printers, saying they are a “threat to national security.”
The suit, filed Tuesday by the U.S. government and three private parties, names Google Inc. and Stratasys Corp. and the U,S.
Defense Advanced Research Projects Agency (DARPA), the research arm of the Department of Defense.
The companies say they can’t build or sell printers without court approval.
The suit also names several other 3D printer companies that make printers, including FusedPrinting and Strataflex.
The complaint said the firms have not produced enough 3D printers to meet U.N. requirements for the production of defense products.
The suit also alleges that they use U.A.E. technology for printing parts.
The U. S. government has argued that the printers are essential for the country’s war effort, which relies heavily on the military industrial base.
The lawsuits were filed in the U-S District Court for the District of Columbia.
