| Abstract Scope |
Despite the benefits of better biocompatibility, corrosion resistance, and mechanical properties, Additively Manufactured (AM) tantalum acceptance has been limited due to the challenges with complex fabrication. Based on collaboration with Global Advanced Metals, Croom Medical recently launched the L-PBF based TALOSTM technology platform allowing robust tantalum printing capability for medical devices and industrial applications. A key financial aspect of metal AM is the material costs which can be significantly reduced with powder reuse. In recent work, Global Advanced Metals and Croom demonstrated multiple tantalum AM builds with minimal changes in mechanical and microstructural properties. This presentation will examine the effects of tantalum powder reuse on build microstructure and microhardness. EBSD was performed on polished blocks and tested tensile coupons to examine the grain size, orientation, and texture changes. Sample microhardness across different builds were also examined to gain insights on microscale mechanical properties. |
