Several U.S. universities are integrating hands-on tools like 3D printing into engineering education, replacing traditional lecture-based models. At Ohio University, engineering technology student Brandon Petrie and his team have engaged over 1,000 K-12 students, using Niryo Ned 2 desktop robots and 3D printers to introduce manufacturing technology. Students program robots to perform sorting tasks and design models via tools like Minecraft, witnessing the transformation of digital designs into physical objects. This 'learning by doing' approach aims to overcome geographic resource limitations, enabling youth in remote areas to intuitively understand manufacturing processes and machine communication logic. For the metal 3D printing industry, this fosters a new generation of talent with additive manufacturing mindsets, building foundational knowledge of digital fabrication and layer-by-layer material deposition from early education, thus cultivating potential users and innovators for future metal powder printing technologies.
