An article [1] about this, describing the inspiration from CT scans for the technique used here to 3D print, is pretty interesting. Below is a quote from it:<p>"They were inspired by the 3-D imaging used to make CT scans. The medical imaging technique rotates a scanner around a patient’s body and constructs a 3-D image from reflected X-rays. The new printing method does this in reverse. The researchers developed software to turn a 3-D design into a light field that’s projected into a rotating vat of photocurable materials."<p>[1] <a href="https://cen.acs.org/materials/3-d-printing/Speeding-3-D-printing/97/i5" rel="nofollow">https://cen.acs.org/materials/3-d-printing/Speeding-3-D-prin...</a>
