Examples: Stainless steel offers good strength and corrosion resistance, but heavier than titanium; Aluminum offers lightweight properties but with lower strength; Nickel alloys boast high-temperature performance but can be expensive. |
| Biokompatibilita | Non-toxic and biocompatible, ideal for medical implants | Biocompatibility varies. Stainless steel is generally biocompatible for some implants, but some grades may require additional surface treatments. Aluminum is not biocompatible and can corrode in the body. Nickel alloys can be biocompatible but some grades may cause allergic reactions. |
| Vlastnosti prášku | High melting point requires specialized printing techniques, flowability can be an issue for some powder types | Melting points vary. Steel and nickel alloys often have lower melting points than titanium, making them easier to print. However, these powders can be more susceptible to oxidation during printing. Aluminum powders are highly reactive and require inert printing environments. |
| Náklady | Relatively expensive due to complex production processes | Costs vary depending on the material. Steel powders are generally cheaper than titanium, while aluminum powders are even more affordable. Nickel alloys can be quite expensive, depending on the specific composition. |

FAQ
Q: What is the difference between commercially pure titanium vs titanium alloy powder?
A: Commercially pure titanium powder has 99.5-99.9% titanium content with low oxygen, nitrogen and carbon. Titanium alloy powders like Ti-6Al-4V contain aluminum, vanadium, or other elements to enhance properties like strength.
Q: What particle size titanium powder is optimal?
A: For pressing and sintering 75-150 microns is common. For additive manufacturing processes, finer 15-45 micron powder is preferred to achieve good resolution.
Q: Does titanium powder require special handling precautions?
A: Yes, titanium fines are flammable and create explosion hazard. Inert gas blanketing and proper grounding is used. Water contact causes hydrogen absorption issues.
Q: How to determine which titanium grade is best for my application?
A: Consult closely with potential suppliers on technical requirements. Ti-6Al-4V is the most common grade but others like Ti-6Al-7Nb suit specific needs. Get test samples to evaluate performance.
Q: What methods can produce titanium powder suitable for 3D printing?
A: Gas atomization and plasma spheroidization create fine spherical titanium powders optimal for additive manufacturing. Hydride-dehydride and mechanical milling methods also produce printable powder.
Q: What post-processing is required on additively manufactured titanium parts?
A: Hot isostatic pressing (HIP) helps eliminate porosity in printed parts. Additional heat treatments, surface finishing, and machining may be needed depending on final properties and tolerances required.
