3D printers are often used for tasks such as printing prototypes, but the objects they print are often not as strong as traditionally constructed objects. This is because the printed object consists of layers of material printed instead of a solid object. Thanks to research conducted by Texas A&M University, the latest 3D printed objects are now 275% stronger than regular 3D printed objects.
Dr. Brandon Sweeney and his mentor, Dr. Micah Green, developed a new technology that involves depositing a layer of carbon nanotubes on the outside of a plastic filament for 3D printing. The filament is then used in a conventional 3D printer to print the object in a conventional manner. Once the printing process is complete, the object is placed in a solid state microwave source (essentially a dedicated microwave oven). The heat generated is concentrated in the carbon nanotubes, causing the plastic in a particular area to melt only with the surrounding plastic. In this way, the plastics are selectively "welded" together at the boundaries between the layers.
Sweeney said: "The basic idea is that 3D printing parts can't simply stick in the oven because it's plastic will melt together. We realize that we need to learn from the traditional concept of welding parts, where you will use ignition Sources (such as TIG weldments) to weld the parts, you are not melting the whole part, just put the heat where you need it."
The technology has been licensed to local startup Essentium Materials, which plans to commercialize it. Researchers hope that the microwave system can be installed directly in the printer, so printing and electromagnetic welding can be performed on the same machine.
