Additive Manufacturing (AM)
Overview
This resource contains materials related to Additive Manufacturing. Feel free to use any of the materials and modify them as needed for your class, If you modify them, please resubmit them to SLAM Resources.
Section 1 - Introduction to Additive Manufacturing
This chapter is intended to introduce the reader to the fundamentals of three-dimensional
printing (3D printing). The reader will get an overview of these paradigm shifting machines, and learn of the history of additive manufacturing, dating back to the 1980’s. This chapter will also cover some of the specialized software that drives 3D printing, as well as the general framework for several popular AM technologies. Some of the objectives of the chapter include: 1) Defining the term “additive manufacturing” (AM), 2) Providing an overview of the history surrounding this technology, 3) Understanding “layers” and the parts of the slicer, the program that drives a 3D printer, and 4) Learning to follow the basic workflow as it applies to nearly all AM machines.

Future contributors may use these materials as foundation for their new methods or materials. This “Open use” is predicated on the improved/extended material being returned to the SLAM repository so that the material will continue to grow.
Section 2 - Fundamentals of CAD for AM
This chapter introduces computer-aided design (CAD) from a theoretical and practical perspective with emphasis as to how they apply CAD to additive manufacturing. The reader will dive into a brief history of CAD and how the software has reached its current state. A discussion /exposure to Autodesk Fusion 360, a free program which introduces tools dedicated to 3D printing design will also be presented. This chapter will evaluate Fusion 360 tools and how they apply to AM.
The objectives of the chapter are to: 1) Provide a high-level overview of computer-aided design, 2) Provide a tutorial for Fusion 360’s fundamental design tools, 3) An exposure to additional design environments and capabilities of CAD, and 4) Understand how CAD can be leveraged for use in additive manufacturing
