Titanium (Ti6Al4V) 3D Printing
Titanium is a lightweight metal with high strength and excellent corrosion resistance
Titanium (Ti6Al4V) is a workhorse alloy. Versus Ti grade 23 annealed, the mechanical properties of Ti6Al4V are comparable to wrought titanium for tensile strength, elongation, and hardness. Final parts built in Ti6Al4V receive vacuum stress relief application.
Primary Benefits
- High stiffness and strength relative to weight
- High temperature and corrosion resistance
Design Guidelines for Titanium 3D Printing
| Normal Resolution | High Resolution | |
|---|---|---|
| Max Part Size | 250 mm x 250 mm x 300 mm | 71 mm x 71 mm x 80 mm |
| Layer Thickness | 30 microns | 20 microns |
| Minimum Feature Size | 0.381 mm | 0.153 mm |
Tolerances: For well-designed parts, tolerances of ±0.076 mm plus ±0.0254 mm/mm can typically be achieved. Note that tolerances may change depending on part geometry.
Applications for 3D-Printed Titanium
Due to its light weight, high strength, and excellent high temperature and corrosion resistance, titanium is often used for aerospace, industrial, and medical applications. Common uses include:
- Compressor blades and discs
- Rings for jet engines
- Airframe and space capsule components
- Surgical instruments
- Medical implants
