3D Printing, also known as additive manufacturing and in industrial circles as rapid prototyping, is the process of building an object using a machine that puts down material layer by layer until the desired object is formed. Such printers use specifications generated by computer modeling applications or by 3D scans of existing objects. This process of creating 3D models is much faster than many traditional methods of creating prototypes or replicas of existing objects, facilitating an innovative culture of learning in which students can quickly move from imagination to the production of a solid model
