MATERIALS AND MANUFACTURING
Learning Objectives • Define additive manufacturing • Explain the origin of additive manufacturing • Describe how the use of additive manufacturing is changing manufacturing • Describe the basic additive manufacturing process • Differentiate between additive manufacturing and CNC manufacturing • Describe the use of CAD in additive manufacturing • Describe the use of computers in additive manufacturing • Describe the use of STL files • Describe the types of additive manufacturing materials • Describe the different methods for layer construction • Classify additive manufacturing processes • Describe the benefits of additive manufacturing • Describe the future of additive manufacturing Additive Manufacturing Safety This course 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 course, users will be able to identify AM hazards, understand common safety standards, and safely operate AM equipment.
• Understanding Safety Data Sheets • Maintenance and Lockout/Tag-Out • Final Review Learning Objectives • Describe additive manufacturing and the importance of AM safety • Describe common AM methods • Describe different types of personal protective equipment • Describe AM mechanical hazards and how to protect against them • Describe AM electrical hazards and how to protect against them • Describe AM thermal hazards and how to protect against them • Describe AM radiation hazards and how to protect against them • Describe AM airborne hazards and how to protect against them • Describe proper cleanup and disposal for AM methods • Describe the information on a Hazard Communication Standard label • Describe safety data sheets • Describe maintenance and lockout/tag-out procedures The Basic Additive Manufacturing Process This course 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. • Describe general post-processing safety • Describe AM material-handling safety
