FinnTEC fills the Helsinki convention center every two years with manufacturing technology and related stuff. I couldn't find anything too revolutionary, a lot of 4- or 5-axis machining centers running programs where they didn't machine anything, just hovered the tool above the workpiece. The 3D printers which print ABS-plastic are becoming more common. The price for one I looked at was 13 keur, not too bad.
