Joining and Repair of Additively Manufactured Components
Despite additive manufacturing's exciting promise to revolutionize manufacturing, to become pervasively accepted, manufacturers will need to know how it can be repaired and or joined in assemblies. In this presentation, attendees will learn how conventional arc welding, friction stir welding, and vacuum brazing can be utilized to join and repair materials printed via laser and electron beam powder bed fusion. Through a combination of metallographic analysis and mechanical properties, the author will show the opportunities and risks when considering joining of additive manufacturing hardware to itself and wrought products.

Fused Granular Fabrication (FGF) vs. Fused Filament Fabrication (FFF)
In recent years, 3D printing with thermoplastic pellet feedstock, otherwise known as Fused Granular Fabrication (FGF), has become a more and more popular form of additive manufacturing. Compared to the more common Fused Filament Fabrication (FFF), it has both its advantages and disadvantages. This presentation will serve as an in-depth comparison of the two technologies. We will help the audience understand the similarities and differences of each, as well as when it is appropriate to use one over the other. This will be achieved by discussing the advantages and disadvantages of each, using real-world industry examples.

Directed Energy Deposition (DED): The Triathlete
Directed Energy Deposition (DED), also referred to as Laser Metal Deposition (LMD), is a triathlete in the Metal Additive Manufacturing space. The technology enables its users to handle several different applications such as FORM, ENHANCE and REPAIR applications. DED can FORM complex geometries, using its powder-fed deposition process. With high deposition efficiency and in-process monitoring, high quality parts can be manufactured 2-100X faster than traditional manufacturing methods. DED can also ENHANCE existing parts or new designs with additional geometrical features with the same base material or other materials with a full metallurgical bond. The AX deposition head and powder feeders can be utilized for laser cladding and functionally gradient material systems to give superior part properties. Lastly, the DED technology can REPAIR high-valued components to reduce down time and scrap. The DED technology has the solutions to take you across the finish line.
