Product overview
3D printed titanium alloy plates are titanium alloy sheets and preformed blanks formed layer by layer using advanced additive manufacturing technologies (such as laser selective melting SLM and electron beam melting EBM). This technology breaks through the limitations of traditional processing, realizes the integrated manufacturing of complex structures, has extremely high material utilization and customization characteristics, and is widely used in high-end fields such as aerospace and medical implants.
Core features
Excellent mechanical properties: Through process optimization, the tensile strength in the vertical printing direction ≥ 1100MPa, which is 10%-15% higher than that in the horizontal direction, meeting the requirements of severe working conditions.
High compactness: Optimized relative density ≥ 99.5% and pore size ≤ 50μm, ensuring the internal quality of the material.
Controllable surface quality: The original printed surface roughness Ra=10-30μm, and the polished surface can reach Ra≤0.8μm, meeting the strict requirements for surface finish for medical implants.
Low residual stress: Heat treatment and substrate stripping technology are used to ≤ residual stress of 100 MPa, effectively preventing deformation and cracking.
Technological process
Powder preparation
Plasma Rotary Electrode Method (PREP) is used for milling, with a powder particle size of 15-45μm and a sphericity of > 95%, ensuring the stability of the printing process and the quality of forming.
Printing parameters (SLM process)
Laser power: 200-400W
Layer thickness: 30-50μm
Scanning speed: 800-1200mm/s
Post-processing
Hot isostatic pressing: 920°C × 100MPa × 2 h to eliminate internal porosity and increase density.
Vacuum annealing: 700°C × 4 h to optimize the tissue and eliminate residual stress.
Surface finishing
Electropolishing (voltage 10-15 V) or shot peening (Al₂O₃grit) to meet the surface needs of different application scenarios
Quality control and process optimization
Powder quality control: oxygen content ≤0.15%, fluidity ≤ 25 s/50g (Hall flow meter), to ensure print quality from the source.
Multi-laser collaborative scanning: Patented scanning strategy reduces thermal stress and improves forming efficiency by 30%.
Topology optimized support structure: intelligent support design reduces material waste by more than 50% and reduces the difficulty of post-processing.
Advantages over traditional manufacturing
Complex structure integration: It can manufacture internal cavity structures that are difficult to achieve in traditional forging and casting (wall thickness ≤ 0.3 mm), and the material utilization rate ≥ 90% (traditional forging is only 20%-40%).
Fast Delivery: No tooling required, shorter lead times by 70%, suitable for low-volume customization and rapid iterations.
High degree of design freedom: It supports lightweight structures such as dot matrix and hollow to achieve the best balance between performance and weight.
