| Abstract Scope |
CoCrMo alloys have a long successful clinical history both in the orthopaedic and dental industry for implantable devices. There is interest in the orthopaedic industry to investigate alternative alloys for patients who may be allergic to elements found in CoCrMo alloys, such as Cobalt, Chromium and although only found as a trace element, Nickel. Johnson & Johnson 3D Printing Center of Excellence has partnered with Carpenter Technology Corporation to develop two nickel-free stainless-steel alloys for Additive Manufacturing. One alloy is known as CarTech® BioDur 108 and the second alloy is new, simply referred to Ni-Free AA (Alternative Alloy). Both materials are atomized to produce powder for experimentation using the additive manufacturing technology, laser-based powder bed fusion (LPBF). LPBF parameter will be optimized. Static mechanical properties, chemistry, density and microstructure will be presented. |
