Ordinarily, if you want to change the shape in which an object is 3D-printed, you have to alter the computer model that tells the printer what to do. A new and simpler technique, however, allows the printer to initiate the changes itself, as the print job is in progress.
The technique was developed at Illinois Northwestern University, by a team led by Assoc. Prof. Cheng Sun.
It s applied to an existing type of 3D printing known as digital light processing (DLP), in which focused patterns of ultraviolet light are shone through the transparent sides of a vat of photosensitive resin – doing so causes select areas of the resin within to polymerize into layers of solid material. The first layer forms on a submerged build platform, which is incrementally raised so that successi
