1. A method for preventing feed sheets from sticking together in a 3-D printer comprising:
lowering a felt tamp onto a stack of feed sheets, each feed sheet having a central region and edges;
positioning a plurality of edge flickers in positions to bend the edges of a top sheet downward as the felt tamp lifts the top sheet upward;
lifting the top sheet off the stack of feed sheets with the felt tamp;
further comprising brushing the felt tamp periodically with a brush to prevent fiber matting;
wherein, a second sheet on the stack of feed sheets does not adhere to the top sheet as the top sheet is lifted by the felt tamp because of the bent edges of the top sheet.
