Acetabular Cups

DMT 3D metal printing technology brings a number of benefits when applied to the manufacture of orthopedic implants. In a recent comparative study, measured against the titanium plasma spray (TPS) process, and carried out on ace-tabular cups, the 3D metal printing process delivered an 83% improvement in porosity, a key attribute for the promotion of bone tissue ingrowth. The results of tensile stress and shear stress tests also showed significant improvements of 17% and 7% respectively. The 3D laser coating process is not only superior in quality, the specially developed InssTek MPC machine is less expensive than most TPS machines. Cycle times for the 3D laser coating process on an ace-tabular cup range between 12 minutes and 18 minutes, significantly quicker than alternative technologies.
