Here we shared the statues of two couples. One statue has been covered with clear acrylic oil and the other has not. The clear oil can eliminate the whitish coating. But we need to control the usage or else it may look too oily.
Solution
Step 1: To produce full-color prints, a CAD model that contains the color information need to be built. Based on the photos sent from the client, the modelers build the 3D model of the couples.
Step 2: A rolling batch leaves a uniform layer of sandstone-like powder. From there two printing heads pass over the batch, coloring and adhering to the object at the same time. The batch of powder then makes another pass, until the object is completed.
Step 3: After printing, the parts are then coated with cyanoacrylate (super glue) or a different infiltrant to improve part strength and enhance the vibrancy of the colors. A secondary epoxy layer can then also be added to further improve strength and color appearance.
