What we print in
Materials
We print in two metals, and only two. Grade 23 titanium (Ti-6Al-4V) and 17-4 PH stainless steel. Here's what each one is good at and how to pick between them.
Grade 23 titanium
Grade 23 titanium (Ti-6Al-4V)
Grade 23 titanium gives you an excellent strength-to-weight ratio, high corrosion resistance, and biocompatibility. That makes it the go-to metal for implants and for parts that need to be light and strong at once. It's behind most of our medical work.
For fatigue critical parts, hot isostatic pressing (HIP) closes internal porosity and improves fatigue life. We coordinate HIP through trusted partners as part of the build.
17-4 PH stainless
17-4 PH stainless steel
17-4 PH is hard, strong, and holds up to heat. It stands up to rough use, which makes it a good fit for suppressors, tooling, and rugged hardware. When weight isn't the priority, 17-4 is often the smarter choice.
To reach full strength, 17-4 is age hardened with an H900 heat treat. We coordinate H900 aging through trusted partners after printing.

Compare at a glance
Same process, two very different metals. Here's how Grade 23 titanium and 17-4 PH stainless stack up against each other.
| Property | Grade 23 titanium | 17-4 PH stainless |
|---|---|---|
| Best known for | Strength-to-weight and biocompatibility | Hardness and heat tolerance |
| Strength-to-weight | Excellent | Good |
| Corrosion resistance | Very high | High |
| Heat tolerance | Good | Very good |
| Biocompatible | Yes | Not for implants |
| Common uses | Implants, suppressors, light strong parts | Suppressors, medical instruments, tooling |
| Post-processing partners | HIP for fatigue-critical parts | H900 age hardening |
