Learning Objectives By the end of this section, students will be able to: Over 100 different alloys are either commercially available or have been proven in the laboratory as suitable for AM. These alloys cover all the primary classes, with…
Learning Objectives By the end of this section, students will be able to: Polymers have been widely available in AM since the beginning of rapid prototyping resins. However, many of the early polymeric materials for AM were only suitable for…
Figure 3.1 This 3D printed glass structure, one of several by innovative designer and architect Neri Oxman on display at the Cooper Hewitt Smithsonian Design Museum, required precise control and materials to maintain structure and produce the texture, strength, and light effects.…
Choices for AM technology are extensive and distinct, with each option offering unique benefits and extensive processes. The most common processes are vat-based processes, powder processes, liquid addition processes, molten material processes, and solid material processes. Each requires expertise and…
Learning Objectives By the end of this section, students will be able to: Once an AM part has been processed using any of the aforementioned processes, the part will most likely endure subsequent processing steps on its journey to become…
Learning Objectives By the end of this section, students will be able to: Sheet Lamination Process Architecture Sheet lamination process architecture is defined as an additive manufacturing process in which an ultrasonic transducer attached to a 3-axis gantry fuses feedstock of…
Learning Objectives By the end of this section, students will be able to: EBM wire process architecture The Electron Beam Melting wire process is used to melt metal wire feedstock with an EBM gun that discharges directly in the melt weld pool.…
Learning Objectives By the end of this section, students will be able to: Material Jetting System Architecture Material jetting is an AM process in which droplets of specialized materials sometimes referred to as ink are selectively applied to a build surface.…
Learning Objectives By the end of this section, students will be able to: Powder Bed Fusion Laser Metal System Architecture For metallic powder bed systems, the basic machine architecture consists of the following: Figure 2.5 Basic architecture of a metal powder bed…
Learning Objectives By the end of this section, students will be able to: Stereolithography (SLA) is the most common vat-based process. It has traditionally held the title of being one of the oldest 3D printing technologies still on the market and…
