Abstract: The invention relates to a 3D printer. The 3D printer includes a first feeder containing a metallic powder first print material, a second feeder containing a metallic powder second print material, delivery means that sprays the print materials, a holder holding a substrate, and a controller. As the print materials are sprayed from the delivery means the controller, which is computerized, adjusts the relative disposition of the delivery means and substrate, and the controller controls the first and second feeders to each feed their print material to the delivery means, so that the print materials form a 3D article on the substrate wherein different parts of the 3D article have different characteristics due to the different print materials or proportions thereof being used for different portions of the 3D article.
