Many companies are starting to recognize the benefits additive manufacturing (AM) offers in terms of speed, simplicity, reliability, and cost. Additive manufacturing is a process in which a three-dimensional computer model design s built into a physical object by joining thin layers of material. AM is a versatile field that encompasses a variety of methods, materials, and applications.
The one-hour courses in this bundle explain the fundamental concepts of additive manufacturing, including the main principles behind AM and the safety precautions to take during the process. These courses also introduce the basic steps in additive manufacturing and discuss the variety of methods and materials that are used to create AM products.
Intro to Additive Manufacturing
This class introduces users to additive manufacturing (AM) processes by outlining the history of AM, describing AM technology, and exploring current and future additive manufacturing applications.
This class describes the various safety hazards involved in additive manufacturing (AM) and the precautions operators should follow to protect themselves. AM methods and processes involve the use of moving and hot components, hazardous materials, and devices that produce radiation. Operators must be aware of these hazards as well as the safety protocols used to reduce them. For example, all AM materials have specific handling guidelines, including the required personal protective equipment (PPE) and ventilation for that material.
Though many AM safety protocols will be familiar to anyone who has worked in a manufacturing environment, there are also hazards unique to AM. Knowing these hazards and safety precautions will help ensure that an AM operation runs smoothly, efficiently, and safely. After taking this class, users will be able to identify AM hazards, understand common safety standards, and safely operate AM equipment.The Basic Additive Manufacturing Process
This class provides an overview of the build process used in additive manufacturing. Upon completing "The Basic AM Process," users should know the eight basic steps involved in creating an AM product.
Additive Manufacturing Methods and Materials
Additive Manufacturing Methods and Materials provides users with an overview of the different processes used in additive manufacturing. This class also details the materials used in each process and any additional considerations specific to those materials.
Though there are some design limitations with DFAM, such as part size and material choice, the process is mainly characterized by the opportunities it provides engineers. After taking this course, users will understand key DFAM concepts, such as functional complexity and hierarchical complexity, the basics of AM production processes, and how DFAM concepts related to basic AM production.Additive Manufacturing Materials Science
"Additive Manufacturing Materials Science" provides a comprehensive overview of the materials that can be used with additive manufacturing (AM) processes. AM materials include a variety of polymers, metals, composites, and ceramics. Each material is distinguished from another material by microstructure, mechanical and physical properties, and life cycle. Different AM processes require the use of different AM materials. Therefore, an individual must understand materials’ science to ensure proper material selection.
Understanding the materials that are compatible with additive manufacturing processes is an essential part of AM process success. After completing this class, users will not only be able to distinguish between thermoplastic and thermoset polymers, ferrous metals and nonferrous alloys, and ceramic and composite materials, but users will also be able to determine which material type is most appropriate for use with a specific AM process.Integrating Additive Manufacturing with Traditional Manufacturing
"Integrating Additive Manufacturing with Traditional Manufacturing" discusses the factors manufacturers should consider when adding an additive manufacturing (AM) component to a traditional manufacturing operation, including cost, logistics, and best uses of AM with traditional manufacturing, among other concerns. Originally used for prototyping, AM has increasingly found more roles in traditional manufacturing processes, such as creating tooling or end-use parts. However, because the procedures and tools are so different, combining the two kinds of manufacturing requires considerable adjustments.
Logistical concerns of integrating AM with traditional manufacturing include purchasing the correct machines and updating safety protocols. Design concerns involve upskilling engineers so that they can take full advantage of AM capabilities. After taking this course, users will understand how to take full advantage of AM as a tool to augment a traditional manufacturing operation.Additive Manufacturing as a Secondary Process
"Additive Manufacturing as a Secondary Process" provides a comprehensive overview of the way in which manufacturers can use additive manufacturing (AM) as a secondary, or indirect, process. AM methods can make a variety of tooling, such as molds and patterns, for use in several different casting, forming, and molding processes. Using AM as a secondary process benefits traditional manufacturing processes by reducing costs associated with lead time, tooling, and labor. An individual must understand the different advantages and disadvantages associated with AM as a secondary process prior to determining whether or not to utilize it.
Knowledge about AM secondary processes and their benefits is important in order to understand the full impact that AM has upon traditional manufacturing. After completing this class, users will be able to identify the traditional manufacturing areas that benefit from using AM as a secondary process and the advantages and disadvantages of doing so.
