Rapid Manufacturing of Co-Cr-Mo Implants by Three-Dimentional Printing Process for Orthopedic Applications
Authors
Abstract:
The fabrication of complex-shaped parts out of (wt %) Co-28Cr-6Mo alloy by three-dimensional printing (3DP) was studied using two grades of the alloy with average particle sizes of 20 and 75 μm. To produce sound specimens, 3DP processing parameters were tuned. The sintering behavior of the powders was characterized by the dilatometric analysis. Batch sintering in argon atmosphere at 1280 °C for 2h was also performed. It was shown that complex-shaped biomedical parts with total porosity of 12-25% and homogenous pore structure can be fabricated by the 3DP process.

A major advantage of additive manufacturing (AM) technologies is the ability to print customized products, which makes these technologies well suited for the orthopedic implants industry. Another advantage is the design freedom provided by AM technologies to enhance the performance of orthopedic implants. This paper presents a state-of-the-art overview of the use of AM technologies to produce o...
full textFabrication of Drug Eluting Ti Implants for Dental/orthopedic Applications
Titanium and its alloys are typically used for fabrication of dental and orthopedic implants as they posses various desirable properties including biocompatibility and corrosion resistance. In spite of such benefits, titanium implants show lack of osseointegration after surgery in minor cases. The objective of this research has been to modify the surface of titanium alloy for medical applicatio...
