  • Patent number: 11446861
    Abstract: A method for producing a three-dimensional object comprising computing a sequence of back-projections describing the three-dimensional object to be formed from different orientation angles of the object, defining a sequence of patterns of light using the back-projections, and irradiating with each of the patterns of light at the respective corresponding orientation angle. According to the defined sequence, a photoresponsive material is capable of altering its material phase, upon irradiation by light, thereby creating a three-dimensional distribution of alterations within the photoresponsive medium which physically reproduces the three-dimensional object, thereby creating the three-dimensional object.
