  • Process for production of three-dimensional objects by means of stereolithography
    Patent number: 6372173
    Abstract: Process for production of three-dimensional objects by stereolithography in which a laser hardens particular areas of constantly succeeding layers of resin fluid. Prior to or during laser light action, the particles, which define physical or mechanical qualities of the object-to-be-produced, will be added into, and/or alternatively, will be produced within the resin fluid, leading to a resin-fluid-particle-mixture. The particles are integrated into the resin and/or compound with resin and/or other particles by means of laser light action or ultrasonic mixing.
