A Research in London was done on Titanium Acetabular Cups made through 3D Printing comparing the designs of different 3D printed cups from multiple manufacturers which included: Delta TT (Lima Corporate, Italy) – 3D printed with electron beam melting (EBM), starting from Ti6Al4V powder; Trident II Tritanium (Stryker, USA) – 3D printed with laser rapid manufacturing (LRM), using titanium-aluminium-vanadium alloy (Ti6Al4V) powder and Mpact 3D Metal (Medacta, Switzerland) – 3D printed with electron beam melting (EBM), starting from Ti6Al4V powder. They were found to have beads, a known by-product of the manufacturing process, which may potentially be released in the human body.
