Abstract
A 3D printing system applies colored powders (e.g., primary colors, white, black, cyan, magenta, yellow, fluorescent colors, metallic) in printed polymer layers for forming a colored 3D object. The system may stabilize a powder layer or color sub-layers thereof, for example with one or more of heat, pressure, and/or high-intensity light. On each layer, powders of various colors may be sequentially deposited in a halftone pattern and stabilized, so as to create a part with a specified arrangement of colors throughout its structure. Benefits include more stable color than strategies involving jetting colored fluids. The arrangement of color on the interior of the part could provide functional or traceability benefits for specific applications. The examples allow for depositing a greater quantity of powder on each fiber base or substrate, decreasing the ratio of fiber to powder and increasing production speed.
