NASA Langley Technology Monitors Quality During 3D Prints

Researchers at NASA's Langley Research Center in Hampton, Virginia have developed a test station capable of in-situ testing of material deposition and layer adhesion in an extrusion additive manufacturing process.

NASA's test station technology addresses the problem of monitoring part quality during the 3D printing process. It includes methods that can be readily integrated into an extrusion apparatus to provide in-situ feedback for closed-loop processing in that apparatus. The novelty is that testing happens in situ as the component is being built.

This test station consists of an extrusion head and a print bed equipped with one or more load cells for measuring the forces exerted as material is deposited.

This technology is perfect for 3D printing applications, rapid prototyping, manufacturing quality assurance, and many other applications.

NASA Langley Research Center is looking for partners to commercialize this technology. For more information about this technology, please contact NASA Langley’s Technology Gateway!
