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 | 9.6 in. x 9.6 in. x 13.0 in. | 3.5 in. x 3.5 in. x 2.7 in. |
| Layer Thickness | 0.0012 in. | 0.00079 in. |
| Minimum Feature Size | 0.015 in. | 0.006 in. |
| Normal Resolution | High Resolution | |
|---|---|---|
| Max Part Size | 245mm x 245mm x 330mm | 88mm x 88mm x 70mm |
| Layer Thickness | 30 microns | 20 microns |
| Minimum Feature Size | 0.381mm | 0.153mm |
Tolerances: For well-designed parts, tolerances of ±0.003 in(0.076mm) plus ±0.001 in./in. (0.0254mm/mm) can typically be achieved. Note that tolerances may change depending on part geometry.
