3D Systems, one of the big, incumbent 3D printer makers, is suing Formlabs, an innovative new 3D printer company that prints in resin (see previous mentions), for patent infringement. They've also named Kickstarter to the suit.
3D Systems' complaint asserts that the sale and use of the Form 1 3D printers sold by Formlabs and Kickstarter infringe a U.S. patent relating to stereolithography. Formlabs sold the Form 1 3D printers to backers of its Kickstarter campaign in September and October 2012.
"3D Systems invented and pioneered the 3D printing technology of stereolithography and has many active patents covering various aspects of the stereolithography process," said Andrew Johnson, General Counsel of 3D Systems. "Although Formlabs has publicly stated that certain patents have expired, 3D Systems believes the Form 1 3D printer infringes at least one of our patents, and we intend to enforce our patent rights."
Many of the key patents in 3D printing start expiring in 2013, and will continue to lapse through '14 and '15. Expect a big bang of 3D printer innovation, and massive price-drops, in the years to come.
