In a paper entitled “ Visualizing the Invisible: A Guide to Designing, Printing and Incorporating Dynamic 3D Molecular Models to Teach Structure-Function Relationships ,” a group of researchers from the University of Nebraska discusses the importance of using three-dimensional models to help students understand critical biology and chemistry concepts. Teachers, the researchers point out, often rely on two-dimensional images to teach complex three-dimensional concepts, such as the structure of molecules, but students cannot fully grasp the concepts using only 2D images. Kits with 3D models exist for teaching purposes, but they “cannot handle the size and details of macromolecules.” 3D printing, however, allows instructors to create detailed custom models of molecules of any size. “For example, protein models can be designed to relate enzyme active site structures to kinetic activity,” the researchers state. “Furthermore, instructors can use diverse printing materials and accessories to demonstrate molecular properties, dynamics, and interactions.” […]
