ผงไทเทเนียม AM สำหรับการผลิตสารเติมแต่ง


With exceptional strength-to-weight ratios, corrosion resistance, and biocompatibility, titanium is a highly valued material for additive manufacturing across aerospace, medical, automotive and industrial applications. This overview explores the different titanium am powders, their corresponding properties, post-processing treatments, leading global suppliers, and example use cases by industry.

ภาพรวมของ titanium am powders

Key properties make titanium such an ideal material for powder bed fusion and directed energy deposition AM processes:

  • High strength – often exceeding annealed titanium while rivaling Ti-6Al-4V
  • Low density – high strength-to-weight ratio, reduced printed part weight
  • Corrosion resistance – protective surface oxide shield
  • Biocompatibility – suited for medical devices and implants
  • Ability to alloy – tailor properties like strength and hardness
  • Cost-effectiveness – lower material waste versus machining from blocks
  • Buy-to-fly ratios exceeding 90%+ – optimized designs save weight and material

Paired with the design freedom AM facilitates, titanium unlocks new potential applications.

Titanium Alloy Powder Options for AM

Popular titanium alloys leveraged today include commercially pure grades, alpha and alpha-beta alloys and novel proprietary grades like Titanium 6242.

Common Titanium Alloy Compositions

CP Ti Grade 1≤ 0.20≤ 0.18
CP Ti Grade 2≤ 0.30≤ 0.25
คุณ-ชัล-เฮวี5.5-6.53.5-4.5≤ 0.25≤ 0.13
Ti 62425.8-6.8≤ 0.30≤ 0.20Mo, Zr

Trace oxygen, nitrogen and carbon are strictly limited to ensure optimal AM processing and mechanical properties.

Specifications for titanium am powders

High purity, spherical titanium powder with controlled particle size distribution is required for defect-free, dense AM components.

Titanium Powder Particle Size Distribution

ช่วงขนาด15 – 45 μm
Mean Particle Size25-35 μm

Sphericity promotes powder spreadability. Controlled distribution prevents segregation issues during application and recyclability.

Post-Processing Procedures for AM Titanium Parts

Common post-treatment options for additively manufactured titanium components include:

Post-Processing Methods

Stress Relieving

Low temperature aging eliminates residual stresses from the build process, preventing potential warpage and cracking.

Surface Finishing

Enhances surface finish for precision dimensions, break sharp edges or improve aesthetic appearance.

กด isostatic ร้อน

Densifies any internal porosity by simultaneous elevated temperature and isostatic pressure application. Required for dynamic end-use applications.


Alters microstructure of Ti-6Al-4V and other titanium alloys to enhance mechanical properties like ductility and fatigue life.


Brings high precision dimensions and surface finishes for bearing and sealing surfaces on AM near-net shape parts.

Additive Manufacturing Techniques for Titanium Powder

Modern metal 3D printing uses micro welding of fine titanium to construct complex components. Two common approaches include:

Comparison of Titanium AM Process Options

วิธีคำอธิบายประโยชน์ข้อ จำกัด
Powder Bed FusionLaser or e-beam fuses regions of powder bed selectively according to digital modelExceptional geometric capabilities and material versatility suitable for end-use functional titanium componentsSlower build speeds than DED; size limitations from machine bed
Directed Energy DepositionFocused heat source melts metal powder spray nozzleLarger components possible; Cumulative build area. Ideal for repairs and coatings.Poorer surface finish; Higher porosity – requires extensive post-processing

Laser based approaches currently see the widest adoption for printing high purity titanium alloys thanks to precision and material performance.

แอปพลิเคชันของ titanium am powders

Thanks to titanium material advantages like high mechanical performance per unit weight combined with AM design freedoms, applications include:

Industries Adopting Titanium AM Parts

The Linde GroupTi-6Al-4V, Grade 2, 23, 5$200 – $600
Wolfram Metal PowderTi-6Al-4V, Grade 5$100 – $500
Sandvikคุณ-ชัล-เฮวี$120 – $310

Prices depend significantly on purity standards, powder size parameters, certified chemistry, and purchase volumes.


What titanium alloy grade is best for medical or dental AM parts?

Medical grade 5 titanium with strict chemistry controls is recommended for bio-inert implant applications requiring optimal biocompatibility and high fatigue performance.

Why is low oxygen content critical for titanium print powders?

High oxygen leads to excess titanium oxides reducing fusion capabilities, ductility, fatigue life and mechanical performance. Oxygen is limited to remain under 0.18-0.2% levels.

What titanium alloys benefit the most from post-processing treatments?

Prominent dual heat treatments for Ti-6Al-4V enhance tensile strength while improving ductility. Grade 2 titanium achieves the highest tensile gains from annealing relieving followed by aging response.

Is surface finishing required for Titanium AM parts?

Certain applications require dimensional accuracy, tribological, aesthetic or inactivation needs best addressed by surface enhancement – including precision CNC machining, grinding/polishing, EDM, shot peening, anodization, plasma electrolytic oxidation etc.

How should suppliers be evaluated for printing titanium powder orders?

Leading critical characteristics used by additive manufacturers and designers for qualifying titanium powder suppliers beyond reasonable pricing include: spherical morphology, tight control of particle size distribution, extremely low gaseous impurity contents (especially oxygen and nitrogen), lot traceability through stringent quality management system, responsive technical expertise, sampling availability and certifications proving standardized in-house testing protocols.
