What is one advantage of additive manufacturing?

Additive manufacturing, commonly known as 3D printing, is particularly renowned for its ability to create complex geometries. This is a significant advantage because traditional manufacturing methods often involve subtractive processes that rely on cutting away excess material. Such methods can limit the shapes and internal structures that can be feasibly produced. In contrast, additive manufacturing builds objects layer by layer, allowing for intricate designs and features that would be challenging or impossible to achieve using conventional techniques.

For example, with additive manufacturing, one can incorporate internal channels, lightweight lattice structures, and highly detailed designs that enhance functionality while using less material. This capability not only opens up new design possibilities in various industries—such as aerospace, medical device fabrication, and custom consumer products—but also enables innovative approaches to enhance performance and reduce material waste.

While the other options may contain elements that can be associated with additive manufacturing, they do not capture this distinctive capability for creating complex shapes as effectively. For instance, lower production costs can be achieved in some scenarios, but the initial setup may still incur significant expenses. Likewise, environmental sustainability is a growing consideration, but it depends heavily on specific practices and materials used in the additive process. Additionally, faster material processing times vary widely based on the technology and design being used
