3D Systems Corp. announces it has completed its acquisition of materials developer and manufacturer RPC Ltd. RPC, now a wholly owned subsidiary of 3D Systems, will continue to manufacture and distribute from its headquarters in Marly, Switzerland, where it has developed 16 stereolithography (SL) materials for SLA systems. "The combination of RPC and 3D Systems allows us to add a greater materials focus to the high-quality hardware customers have come to expect. We plan to provide a full range of materials with comparable or improved properties," said Grant Flaharty, senior vice president of worldwide sales and marketing for 3D Systems.
