Transforming AM Through Materials Freedom Materials Influence Introduction of high-performance AM materials Advantages of 3D printed copper Advantages of 3D printed pure aluminum Customization

LEARNING OBJECTIVES Powerful combination: AM design & materials freedom Advantages of AM composites & standard alloys AM Copper is a game changer

Throughout history, materials have defined our technology. Materials Influence Throughout history, materials have defined our technology. Stone Age Bronze Age Iron Age Silicon Age Age of Composites And now:

Thermal Conductivity (W/(m*K)) Wrought Properties (not printed values) Material Thermal Conductivity (W/(m*K)) Copper 385 Aluminum (pure) 205 Al-6061-O   180 Tungsten 174 Al-6061-T6   167 Al-6061-T4   154 Al-5052-O   144 Al-2024-T351   143 Al-5052-H32   138 Al-7075-T6   130 Al-2024-T4   121 Tantalum 54 H13 24.6 Titanium 22 316L 13->17 Invar 36 12->15 Inconel 625 9.8 Haynes 230 9 Ti64 7.2

Expanding additive materials Aluminum MMC 6061-AM Aluminum Copper Tungsten

Why Expand additive materials? AM can revolutionize parts manufacturing landscape Limited selection restricts economic advantage of AM Only 12 additive metal alloys were available Refractories Conductors Composites High Performance Alloys

Advantages of 3D Printed Copper Highest Printed Conductivity AM part complexity Complex external & internal structures Conformal temperature control channels Increased efficiency Part consolidation Reduced production costs & lead times Photo courtesy of AM Metals, 2018

Advantages of 3D Printed Copper AMCopper-100 8.9 g/cc 30 ksi (210 MPa) 21 ±2 HRB ~109 Gpa* 349 W/mK 84% IACS AMCopper-100XC 8.9 g/cc Pending 21.5 ±2 HRB ~114 Gpa* 90% IACS Density Ultimate tensile strength Hardness Modulus of elasticity Thermal conductivity Electrical conductivity Physical and Chemical Properties (stress relieved) *Not stress relieved

3D Printed PURE ALUMINUM Specific conductivity: 80 (W/mK / g/cc) Corrosion resistance AM part complexity Increased efficiency

3D Printed PURE ALUMINUM A1000-AM 2.7 g/cc 15-16 ksi (100-110 MPa) ~109 Gpa 217 W/mK 226 W/mK Density Ultimate tensile strength Modulus of elasticity Thermal conductivity Thermal conductivity (300°C) Physical and Chemical Properties (stress relieved)

Elementum 3D is creating additive manufacturing materials that are not possible through traditional manufacturing.

Materials freedom is as important to AM adoption as design freedom.
