Fig. 2From: A new 3D printing porous trabecular titanium metal acetabular cup for primary total hip arthroplasty: a minimum 2-year follow-up of 92 consecutive patientsThe picture shows the interface between the two layers of traditional cup (left) and the integration EBM porous structure (right). The EBM technique achieved the melting of thin layers of metal powder, modeling a bulk construct which respects the original metal alloy properties and integrates as a whole trabecular surfaceBack to article page
