To assess the feasibility of manufacturing a dental crown with internal color gradient and graded structure design using additive manufacturing technology, a mandibular first molar was prepared and a monolayer dental crown with 1.5 mm uniform thickness was designed in a dental software (STLC1 ). The monolayer (MOL) crown design was sliced into multiple layers of 0.1 mm thickness and a design for a multi-layer crown was obtained (STLC2 ). A multi-layer crown was manufactured with gradient color and graded structure using a material jetting printer. Different materials with different colors and properties were used and mixed in different ratios during manufacturing to achieve the prospected design. The feasibility of manufacturing such a crown was reported. This report confirms that multi-layer dental crowns with internal gradient color and graded structure is possible when using a multi material jetting printer. This article is protected by copyright.
