Last month a judge ruled in favor of 3D systems in a suit brought against them by DSM Desotech, a chemical production giant. The suit claimed that 3D Systems was involved in anti-competitive business practices for their tie-in model. They require only certain resins to be used within their SLA printers by using an RFID device.

The judge on the case ruled that 3D Systems was not at fault however. The full details of this article can be found here: http://3dprint.com/3906/3d-systems-ruling-dsm-desotech/
