3D printing. Maybe minor but it’s additive instead of subtractive so theoretically less waste. The old heads said 3D would never take over machining but I didn’t agree then and I don’t agree now. Maybe some applications but 3D is superior if we can get the right materials properties and costs.

Hbu?
