Introduction to Additive Manufacturing

Semih Genculu, P.E.

Three-dimensional (3D) printing, also known as additive manufacturing, is a highly flexible manufacturing process that has been used in product development and final parts production for the past 30 years. Greater capabilities, lower prices, and an expanded range of manufacturing materials have vastly expanded adoption of 3D printers over the last decade and a half. 3D printers are used in a variety of industries—such as aerospace, medicine, and education—as
well as in nonspecific custom prototyping. 3D printing uses a fundamentally different process than most methods for traditional manufacturing. Much of modern manufacturing uses subtractive manufacturing processes, beginning with a block of material (e.g., a tube, a bar, or an ingot) and using a variety of tools to remove parts of the initial material to achieve a final design. 3D printers are additive, stacking up and fusing thin layer upon thin layer of a material (or materials) onto a blank platform to achieve a final design. This allows for flexibility and complexity in the manufacturing of 3D-printed items. Four primary properties of 3D printers stem from this unique additive construction method: reduced waste, capacity to create parts with high internal complexity, cost- effectiveness of small production runs, and ease of design modification.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
