MIM Ti-6Al-4V Device Master File
In 2016, Praxis submitted a Device Master File to the FDA for their Ti-6Al-4V material to streamline customer product submissions. Guidance from ISO 10993 was utilized to conduct tests; please contact Praxis for more details.
Praxis’ OrthoMIM technology offers design flexibility and cost savings specifically for orthopaedic devices. OrthoMIM combines two of Praxis’ proprietary Titanium Injection Molding technologies to provide innovative, cost-saving solutions for orthopaedic applications. Our high fatigue performance material (TiRx™) is combined with our innovative netshape surfacing technology (3DT™) to provide complex, netshape surfaces on economical implant bodies. These technologies are described below:
TiRx™ – For Load Bearing Applications
• Outstanding Fatigue Performance (RFB >90ksi @ 10M cycles)
• Meets chemical and mechanical requirements of Ti-6Al-4V
• Integrates seamlessly with 3DT™ to Co-Form high performance implant bodies.
3DT™ provides tailorable surfaces for uncemented devices, cemented devices and monoblock devices. It allows you to economically apply netshape textures to challenging surfaces. Surfaces are co-formed with a grade 5 titanium substrate that is designed to eliminate delamination concerns.
3DT™ is easily customizable, highly repeatable and versatile for implants.
• 3D Ongrowth
• 2D Ingrowth
• Polymer Anchoring Surfaces
3DT™ can be used on:
• Inside surfaces such as femoral knees and monoblock cups
• Compound sections like tibial tray posts that are solid titanium with a porous surface
• Contoured/wrap around surfaces products like femoral stems and acetabular cups
