  • Publication number: 20210146612
    Abstract: An additive manufacturing system has a light permeable base, a build carrier for holding a workpiece and a light source which is arranged to emit light through the light permeable base. The light permeable base and the build carrier are positionable relative to each other in a build dimension in which the workpiece is built up. The system further has a resin vat in which the light permeable base forms a wall portion thereof. The system further comprises a plurality of resin supplies for supplying different light hardenable resins in direct contact with each other in said vat. The system facilitates the rapid manufacturing of a dental restoration having a color gradation.
