The progress of technology, particularly of Additive Manufacturing, has made possible the creation and the subsequent use of custom made 3D devices in hip surgery.

In selected complex cases, the use of custom made stems or cups may also lengthen system's life and improve the clinical outcome. High costs and long time required for the production of customized products are the major limit of this technique in primary arthroplasty, although in selected complex cases, their use is advocated by the surgeons.

Abstract
The progress of technology, particularly of Additive Manufacturing, has made possible the creation and the subsequent use of custom made 3D devices in hip surgery. These customized devices may be implantable (cup or stem) or non-implantable (diagnostic models, simulation models, cutting templates). The commonly used additive manufacturing technologies are: FDM (Fusion Deposition Modeling), SLS (Selective Laser Sintering), EBM (Electron Beam Melting). Each of these is used for specific purposes and has advantages and disadvantages. Several surgical techniques have been described to face most of the hip arthroplasties without the need for custom made devices. However, in complex cases, their use may be useful. 3D models allow surgeons to reach a more accurate diagnosis or to simulate surgery. Thanks to the cutting guides tailored on individual anatomy, surgery may be assisted and simplified, reducing operating times, simplifying the critical steps, decreasing the intra and perioperative risks. In selected complex cases, the use of custom made stems or cups may also lengthen system's life and improve the clinical outcome. High costs and long time required for the production of customized products are the major limit of this technique in primary arthroplasty, although in selected complex cases, their use is advocated by the surgeons.
