I have doubts. 3D printers are effective at replacing casting and (sometimes) stamping. But they don't replace forging, rolling or assembly of moving parts. That is, I think they most replace manufacturing operations which were low labor anyhow. I doubt they'd actually reduce labor in those areas, since the number of people needed for them seems to be one already. If I was looking for an industry to be hit hard by 3D printing technology, I would look at companies which specialize in tooling or warehousing specialized single component parts.
