titanium additive manufacturing Process Methods

Popular titanium AM techniques:

Powder Bed FusionLaser or electron beam melts powder layers
Directed Energy DepositionFocused heat source melts metal powder or wire
เครื่องผูก jettingLiquid bonding agent selectively joins powder particles

Each process has specific advantages depending on the part application and requirements.

Metal Powder Bed Fusion

A powder bed is selectively melted by a heat source layer-by-layer:

ฟิวชั่นเตียงผงเลเซอร์ (L-PBF)Uses laser for melting. Higher resolution.
การละลายของลำแสงอิเล็กตรอน (EBM)Electron beam heat source. Faster build rates.

L-PBF allows finer features while EBM enables higher productivity. Both produce near-full density parts.

Directed Energy Deposition

Focused thermal energy is used to melt metal powder/wire to deposit material layer-by-layer:

Laser Metal DepositionLaser beam
Laser Engineered Net ShapingLaser beam

DED is often used to repair or add features to existing components.

Binder Jetting Process

Liquid bonding agent selectively joins layers of metal powder:

  • Powder spreading – New layer of powder spread over build platform
  • Binder jetting – Printhead deposits binder in desired pattern
  • Bonding – Binders bonds powder particles together
  • Additional drying, curing and infiltration steps are used to achieve full density

Binder jetting produces porous “green” parts that require sintering and infiltration to densify. It offers high-speed printing.

AM Parameters for Titanium

Key AM process parameters for titanium:

ความหนาของชั้น20-100 μm
Laser power (L-PBF)150-500 W
ความเร็วในการสแกน600-1200 mm/s
Beam size50-100 μm
ระยะห่างฟัก60-200 μm

Optimizing these parameters balances build speed, part quality, and material properties.

Post-Processing of การผลิตสารเติมแต่งไทเทเนียม Parts

Common post-processing steps:

สนับสนุนการกำจัดRemove support structures
Surface machiningImprove surface finish
Drilling and tappingAdd screw holes and threads
กด isostatic ร้อนEliminate internal voids and porosity
Surface treatmentsImprove wear/corrosion resistance

Post-processing tailors the parts to meet final application requirements.

Applications of titanium additive manufacturing

Key application areas for titanium AM parts:

การบินและอวกาศStructural brackets, engine parts, UAV components
ทางการแพทย์Orthopedic implants, surgical instruments
เกี่ยวกับยานยนต์Lightweight auto parts, custom prototypes
เคมีCorrosion resistant fluid handling parts
น้ำมันและก๊าซValves, pumps for corrosive environments

AM enables innovative titanium component designs across demanding industries.

Quality Control for titanium additive manufacturing Parts

Critical quality checks for titanium AM parts:

  • Dimensional accuracy – Measure against design using CMMs and 3D scanners.
  • ความขรุขระ – Quantify surface texture using profilometers.
  • ความพรุน – X-ray tomography to check for internal voids.
  • องค์ประกอบทางเคมี – Confirm alloy grade using spectrometry techniques.
  • คุณสมบัติเชิงกล – Conduct tensile, fatigue, fracture toughness testing.
  • การทดสอบแบบไม่ทำลาย – X-ray, ultrasound, penetrant testing.
  • โครงสร้างจุลภาค – Metallography and microscopy to check for defects.

Comprehensive testing validates part quality for functional performance.
