In Brief Disney Research has designed a new 3D printer that utilizes light on photosensitive resin so that models can be printed out as whole objects instead of by the layer, cutting down 3D printing from hours down to just minutes.

Disney Research has patented its design for “a nearly instantaneous” 3D printer that uses light to cure resin selectively to produce an entire model out of a stereolithography file all at once.

“Presently, 3D printing is extremely slow and time consuming. For example, it may take several hours to print a single 3D object even if the 3D object is relatively small,” the patent stated.

It continues, “The 3D printing process that uses conventional 3D printers such as an FFF-based 3D printer is limited in its speed by the speed of the mechanism moving the print head to each new position on a print layer.”

The photosensitive resin to be used by the printer cures with light at specific wavelengths to make sure it doesn’t cure simply by being exposed to ambient light.

“In several test operations, a 3D printer using photo-curing liquids has been proven effective in generating 3D objects in several minutes or less rather than several hours,” the patent asserts.

“The digital file defines not only the outer shell of the 3D object but also defines a unique identifier or identification element to be printed in the inner volume of the 3D object in one or more layers,” Disney stated.
