3D printing of titanium alloys (titanium alloy additive manufacturing) has emerged as one of the most representative technological trends in the field of advanced manufacturing in recent years. By combining the excellent mechanical properties of titanium alloys with the "layer-by-layer build-up and near-net-shape" characteristics of additive manufacturing, this technology is reshaping supply chains in industries such as aerospace, healthcare, and consumer electronics. The following provides a brief analysis from five perspectives: technical approaches, core advantages, application scenarios, existing challenges, and future trends.
I. Breakthroughs in 3D Printing Processes and Technologies
1. Mainstream Manufacturing Technologies
Powder Bed Fusion: Achieves precision molding with a tolerance of ±0.05 mm and improves material utilization by 60%; suitable for manufacturing biomimetic structural components in the aerospace industry.
DLP Photopolymerization: Utilizes photopolymer resin combined with titanium powder for forming, with a shrinkage rate of 3.5%–4.2%; requires software-based precision compensation; suitable for complex components such as turbine blades.
Plasma Arc Directional Deposition: Certified to the aerospace standard AMS 7004, overcoming manufacturing bottlenecks for large-scale aerospace structural components.
2. Material Performance Optimization
Titanium alloy powder sphericity >95%, particle size 15–53 μm, ensuring high densification during forming;
Gradient annealing process eliminates 85% of residual stress; hot isostatic pressing (HIP) treatment increases fatigue life by 3–5 times;
Surface roughness reaches Ra 0.8 μm after sandblasting and polishing.
II. Key Application Scenarios
