Direct ink writing to fabricate porous acetabular cups from titanium alloy
Bio-Design and Manufacturing

Volume 6, Pages 121–135
Acetabular cups, which are among the most important implants in total hip arthroplasty, are usually made from titanium alloys with high porosity and adequate mechanical properties. The current three-dimensional (3D) printing approaches to fabricate customized acetabular cups have some inherent disadvantages such as high cost and energy consumption, residual thermal stress, and relatively low efficiency. Thus, in this work, a direct ink writing method was developed to print a cup structure at room temperature, followed by multi-step heat treatment to form microscale porous structure within the acetabular cup. Our method is facilitated by the development of a self-supporting titanium-6 aluminum-4…
