3D Printer

Today, a three-dimensional printer(3D - printer) has been created combining traditional printing technology with the wisdom of our ancestors. Three-dimensional printing is a manufacturing technique that produces three-dimensional objects by spraying a continuous layer of matter. By using this, they were able to create objects in three dimensions, not in two dimensions.
