3D Printing bimetallic structures with enhanced strength

Posted on

Researchers at Washington State University have devised a novel approach to 3D printing that allows for the simultaneous printing of two different types of steel in a single circular layer. By integrating welding machines into a CNC machines, they leveraged this concept and achieved impressive results. Inspired by the structural complexity of trees and bones, the researchers utilized welding machines integrated within a computer numerical control (CNC) machine to create bimetallic structures. The resulting material demonstrated a remarkable 33% to 42% increase in strength compared to individual metals. Combining a corrosion-resistant, stainless-steel core with an outer casing of cheaper “mild” steel for applications requiring high-performance components. The ability to 3D print with two different metals in a circular layer opens up possibilities for design and manufacturing. Traditionally, printing with multiple metals required pausing the process and changing metal wires.

For startups and small businesses, customization and design flexibility are crucial factors in product development. The dual-metal 3D-printing method offers unprecedented design freedom, enabling enterprises to create intricate and tailored objects that meet specific customer requirements. This level of customization can help new businesses differentiate themselves in the market and gain a competitive edge. It eliminates the need for expensive equipment and complex manufacturing processes. New companies can adopt this technology without a substantial upfront investment by leveraging commonplace and relatively inexpensive tools, such as welding machines.

The costs associated with implementing the dual-metal 3D-printing method can vary based on factors such as production scale, desired quality standards, materials used, and the availability of skilled labor. Conducting a thorough cost analysis and considering the potential benefits and long-term ROI will help new businesses make informed decisions regarding adopting this technology. The technique offers promising applications for various industries, including medical manufacturing and aerospace engineering.
