titanium additive manufacturing Process Methods

Popular titanium AM techniques:

YöntemAçıklama
Toz Yatağı FüzyonuLaser or electron beam melts powder layers
Yönlendirilmiş Enerji BiriktirmeOdaklanmış ısı kaynağı metal tozu veya teli eritir
Binder JettingSıvı bağlayıcı madde toz partiküllerini seçici olarak birleştirir

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:

TipDetaylar
Lazer Toz Yatağı Füzyonu (L-PBF)Uses laser for melting. Higher resolution.
Elektron Işınıyla Eritme (EBM)Electron beam heat source. Faster build rates.

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

Yönlendirilmiş Enerji Biriktirme

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

YöntemIsı Kaynağı
Laser Metal DepositionLazer ışını
Elektron Işını Katmanlı ÜretimElektron ışını
Laser Engineered Net ShapingLazer ışını

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:

ParametreTipik Aralık
Katman kalınlığı20-100 μm
Laser power (L-PBF)150-500 W
Tarama hızı600-1200 mm/s
Kiriş boyutu50-100 μm
Kapak aralığı60-200 μm

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

Post-Processing of titanyum katkılı üretim Parçalar

Common post-processing steps:

YöntemAmaç
Destek kaldırmaDestek yapılarını kaldırın
Yüzey işlemeImprove surface finish
Drilling and tappingAdd screw holes and threads
Sıcak izostatik preslemeEliminate 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:

EndüstriKullanım Alanları
Havacılık ve UzayStructural brackets, engine parts, UAV components
TıbbiOrtopedik implantlar, cerrahi aletler
OtomotivLightweight auto parts, custom prototypes
KimyasalKorozyona dayanıklı sıvı taşıma parçaları
Petrol ve gazValves, 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:

  • Boyutsal doğruluk – Measure against design using CMMs and 3D scanners.
  • Yüzey pürüzlülüğü – Quantify surface texture using profilometers.
  • Gözeneklilik – X-ray tomography to check for internal voids.
  • Kimyasal bileşim – Confirm alloy grade using spectrometry techniques.
  • Mekanik özellikler – Conduct tensile, fatigue, fracture toughness testing.
  • Tahribatsız muayene – X-ray, ultrasound, penetrant testing.
  • Mikroyapı – Metallography and microscopy to check for defects.

Comprehensive testing validates part quality for functional performance.
