This lecture examines key elements of the business case for additive manufacturing. We begin with a discussion of the four key factors that tend to drive the business case for additive manufacturing – labor, tooling, machine costs, and material – examining tradeoffs associated with each. We also touch upon some of the less tangible factors that could influence the additive manufacturing value proposition. We conclude the lecture by presenting five key issues to consider when making the AM investment decision. This edition of the video series does not include the quiz, assessment, or assignment portion as mentioned in the lesson.
