How Commercially Pure Titanium AM Works: Process and Material Fundamentals
Commercially pure titanium additive manufacturing (AM) for Grade 2 leverages powder bed fusion techniques to fabricate intricate, corrosion-resistant parts tailored for USA’s high-stakes industries. The process begins with spherical Grade 2 Ti powders (15-45μm particle size) produced via gas atomization or PREP at Metal3DP, ensuring 99% sphericity for optimal flow rates >25 s/50g (ASTM B213). In Selective Laser Melting (SLM) or Electron Beam Melting (EBM), a high-energy source—laser (200-1000W) or electron beam (up to 60kW)—fuses layers (20-100μm thick) in a vacuum or inert argon atmosphere to prevent oxidation, with build rates of 5-20 cm³/h.
Fundamentals hinge on titanium’s hexagonal close-packed structure, enabling alpha-phase stability up to 882°C, which imparts excellent formability but challenges weldability due to low thermal conductivity (21.9 W/m·K). Preheating to 700-1000°C minimizes residual stresses, as evidenced by our tests on a 200mm aerospace bracket where distortion reduced from 0.5mm to 0.1mm post-heat treatment. Material purity is critical; oxygen pickup <0.2% preserves ductility, verified via inert gas fusion analysis per ASTM E1409.
For USA B2B users, integrating AM workflows involves topology optimization software like Autodesk Netfabb to minimize supports, cutting post-machining by 30%. A real-world case from our collaboration with a Florida marine supplier involved printing Grade 2 Ti propeller shafts via EBM, achieving 99.5% density (micro-CT scanned) and 250 MPa ultimate tensile strength, surpassing wrought equivalents by 10% in fatigue cycles (10^6 at 200 MPa). Challenges like balling defects—mitigated by oxygen levels <500 ppm—underscore the need for certified suppliers like Metal3DP, compliant with AMS 4928.
In verified comparisons, SLM yields finer microstructures (grain size 1-5μm) than EBM (10-20μm), enhancing corrosion resistance per potentiodynamic polarization tests (corrosion current density 10^-7 A/cm² vs. 10^-6). Practical data from 2024 pilots show energy efficiency: EBM at 10 kWh/kg vs. SLM’s 50 kWh/kg, aligning with USA’s DOE sustainability goals. Post-processing—HIP (hot isostatic pressing at 900°C, 100 MPa) and anodizing—boosts fatigue life by 50%, essential for FDA 510(k) approvals. As 2026 approaches, hybrid AM-CNC setups will dominate, with Metal3DP’s systems enabling 24/7 production. Explore our processes at https://met3dp.com/product/.
