Full Color Powder Binding
The model is printed from bottom to top, layer by layer. A roller puts a thin layer of powder on a platform, and a print head places tiny drops of glue at specific locations, printing a thin layer of the model. The platform lowers, and the roller spreads another layer of powder. Coloring is done by combining 4 different pre-colored glues to match the color requested. The model is brittle after the printing process but is strengthened by putting it into superglue. A UV coating is sprayed on it to prevent de-coloration by sunlight.
