Freeform Multi-material Assembly Process

2024: Product Announcement

On June 20, 2024, American researchers from the University of Missouri announced the development of the world's first 3D printer that allows you to create complex devices from several materials - plastic, metal and semiconductor components. It is assumed that in the future the proposed technology will reduce financial costs and time for the creation of new products, as well as reduce waste.

The proposed method is called Freeform Multi-material Assembly Process - the process of assembling free-form objects based on several materials. The system combines elements of traditional 3D printing with laser technologies to produce multifunctional products. The machine contains three key units: one applies an ink-like material, another uses a laser for processing, and a third adds additional functional components according to the purpose of the product.

The process begins by creating a basic structure from a conventional 3D printing thread such as polycarbonate (a type of transparent thermoplastic). A laser then comes into play to convert some elements into a special material called laser-induced graphene. In the third step, additional components are added to enhance the functionality of the final product.

The proposed technology is suitable for the formation of multilayer sensors, boards and even textiles with electronic elements. Robotics, medical devices, wearable gadgets with functions of monitoring vital signs of the body, etc. are called as possible areas of application. In general, according to the authors of the project, their machine "promises to revolutionize the production of new products."^[1]
