This course explains the basics of Additive manufacturing process (AM). Additive manufacturing process is non conventional manufacturing process. Additive manufacturing is a specific 3D printing process.This process builds parts layer by layer by depositing material according to digital 3D design data. “additive manufacturing” better reflects the professional manufacturing process that differs significantly from conventional, subtractive manufacturing methods. For example, instead of milling a workpiece from a solid block, additive manufacturing builds the part up layer by layer from material supplied as a fine powder. Various metals, plastics and composite materials can be used.

The term “additive manufacturing” references technologies that grow three-dimensional objects one superfine layer at a time. Each successive layer bonds to the preceding layer of melted or partially melted material. Objects are digitally defined by computer-aided-design (CAD) software.

First, a thin layer of the powder material is added to a building platform. There, a powerful laser beam melts the powder precisely at certain points specified by the computer-generated design data. Next, the construction platform is lowered and another layer of powder is added. The material is melted once again, which connects it to the layer below at the specified points.

Also you students will understand different steps of AM, classification and how additive manufacturing process are carried out with case study.
