TI  - Feedstock Development for Material Extrusion-Based Printing of Ti6Al4V Parts.
LID - 10.3390/ma15186442 [doi]

AB  - In this work, a holistic approach for the fabrication of dense Ti6Al4V parts via 
      material extrusion methods (MEX), such as fused filament fabrication (FFF) or 
      fused feedstock deposition (FFD), will be presented. With respect to the 
      requirements of the printing process, a comprehensive investigation of the 
      feedstock development will be described. This covers mainly the amount ratio 
      variation of the main binder components LDPE (low-density polyethylene), HDPE 
      (high-density polyethylene), and wax, characterized by shear and oscillation 
      rheology. Solid content of 60 vol% allowed the 3D printing of even more complex 
      small parts in a reproducible manner. In some cases, the pellet-based FFD seems 
      to be superior to the established FFF. After sintering, a density of 96.6% of 
      theory could be achieved, an additional hot isostatic pressing delivered density 
      values better than 99% of theory. The requirements (mechanical properties, 
      carbon, and oxygen content) for the usage of medical implants (following ASTM 
      F2885-17) were partially fulfilled or shortly missed.
