3D ACT Acetabular Reconstruction System

Highly porous titanium alloy acetabular cup and augment system created using 3D EBM printing technology for both primary and more complex acetabular defects Paprosky I – IIIb.

3D ACT Acetabular Cup


Unlike the two-step coated surface of a traditional cup, the 3D ACT cup is naturally integrated reducing the detachment risk of the porous surface. 

3D EBM Technology

TiAl6V4 Trabecular One-Piece Construct

Structural Solidity

Continuity between solid substrate and porous surface

High Porosity

600-800μm pore diameter leading to improved local vascularization, oxygenation and secure fixation

High Friction Coefficient

0.93 Cortical Bone & 1.08 Cancellous Bone

100% Pore Connectivity
