| Number | Title | Issue Date |
| 5130064 | Method of making a three dimensional object by stereolithography A stereolithographic method for constructing an object from a medium capable of solidification upon exposure to synergistic stimulation (e.g. a laser beam). Stacked layers of solidified medium are constructed by exposing the medium to synergistic stimulat... | 07/14/1992 |
| 5120476 | Production of objects Three-dimensional objects are produced by the polymerization of a photopolymerizable liquid medium with the aid of high-energy radiation by continuously introducing the liquid medium in lamina form from a casting means onto the surface of a carrier liquid... | 06/09/1992 |
| 5059359 | Methods and apparatus for production of three-dimensional objects by stereolithography An improved sterolithography system for generating a three-dimensional object by creating a cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synerg... | 10/22/1991 |
| 5031120 | Three dimensional modelling apparatus A system responsive to coordinate information for automatically providing a three-dimensional physical model of a desired geometry and comprising apparatus for selectably solidifying a solidifiable material on a sequential layer by layer basis characteriz... | 07/09/1991 |
| 5014207 | Solid imaging system In a solid imaging system, the beam of a relatively high-powered beam radiation source, and more particularly a laser, is modulated in accordance with its varying vector sweep speed so that substantially constant layer depth is maintained at all scanner s... | 05/07/1991 |
| 4977511 | Photosensitive materials containing ionic dye compound as initiators A process for making three dimensional models is disclosed which is characterized in that a photohardenable composition is used which comprises a free radical addition polymerizable or crosslinkable compound and an ionic dye-counter ion compound, said com... | 12/11/1990 |
| 4575330 | Apparatus for production of three-dimensional objects by stereolithography A system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impingi... | 03/11/1986 |
