About Machina Labs At Machina Labs, we're reshaping manufacturing through advanced robotics and machine learning. Our platform uses the largest 6-axis robots on the market to form 2D sheets of metal into complex 3D parts, layer-by-layer. Traditional sheet metal production was designed for scale, not flexibility.
