4 Background: Terminology Direct Digital Laser Additive Direct Part Mfg there are standards? 4 Additive Manufacturing is Much More Than Just Printing

5 ASTM F42 Sub-Committee on Terminology (F2792) 1. Binder Jetting an additive manufacturing process in which a liquid bonding agent is selectively deposited to join powder materials 2. Directed Energy Deposition an additive manufacturing process in which focused thermal energy is used to fuse materials by melting as they are being deposited 3. Material Extrusion an additive manufacturing process in which material is selectively dispensed through a nozzle or orifice 4. Material Jetting an additive manufacturing process in which droplets of build material are selectively deposited 5. Powder Bed Fusion an additive manufacturing process in which thermal energy selectively fuses regions of a powder bed 6. Sheet Lamination an additive manufacturing process in which sheets of material are bonded to form an object 7. Vat Polymerization 5 an additive manufacturing process in which liquid photopolymer in a vat is selectively cured by light-activated polymerization

6 Background: Technology Primer Additive Manufacturing (AM) materials Polymeric (Nylon, PAEK, ABS-like, etc.) Metallic (Ti-alloys, CoCr, SS 17-4, etc.) Composite, Ceramic, Paper-based AM enables smarter manufacturing 3D Art-to-Part via 2D layer-by-layer Near-net, to net-shape parts Increases the design space Directed Energy Powder Bed Fusion Material Extrusion 6 Increase Product Potential, Reduce Waste (Time, Materials Cost)

7 Background: Potential Benefits 1 st : Affordability Reduce tooling, waste Complexity = Simplicity 2 nd : Smart(er) Manufacturing Integrate processes Support RP & production Traditionally: 9 piece welded duct assembly AM: 2-piece bonded assembly 3 rd : Optimize Product Design Reduce weight, support modularity Multi-functional parts F-35 Representative Parts Oak Ridge National Lab 7 With Additive You Can Design for Functionality
