So is additive manufacturing the same as 3D printing? Apparently not. UC Berkely has a great new tech where you shine light into a special resin to create objects “all at once” rather than in layers. The tech was inspired by the CT medical scan, but in reverse. A CT scan projects energy from many angles to measure an object through transmitted energy measurement, but the printer concentrates the energy at a fixed point to reach a light threshold where the polymer will cross-link and solidify. Doing this a complete object can be made in minutes. You can read all about it in the Berkeley News.
