ColorJet full-color printing technology is a good match for printing large models such as ancient buildings, especially models with simple colors. It has a great competitive price compared with other colorful printing methods.
Solution
Step 1: As the default layer thickness is 0.1mm and sandstone prints have medium tolerance, we need to examine the thickness of all the details to ensure they can all be printed out.
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.
