Spineart developed a specific algorithm to enhance the classic additive manufacturing process resulting in a unique bone-like matrix: Ti-LifeTECHNOLOGY.

Ti-LifeTECHNOLOGY achieves a geometry that would not be possible through classic manufacturing processes. The result is a Titanium porous structure similar to natural trabecular bone.



Over the last decade, Titanium biocompatibility has been demonstrated and accepted by the scientific community. Unlike polymer materials (PEEK), the Titanium porous structure and roughness facilitate bone tissue ingrowth1-2-3.



Additive manufacturing produces highly cohesive device which differentiates the Ti-LifeTECHNOLOGY from non-porous surface treatments and coating techniques (4). The micro-porous scaffold mimics the cancellous bone structure and features interconnected pores (diameter between 0.6 and 0.7mm), with an average of 70-75% overall porosity, that enables cell colonization6. As a comparison, natural bone features around 60% porosity with pore diameter ranging from 0.3 and 1.5mm5-6-7.



Ti-LifeTECHNOLOGY contributes to a unique osteoconductive environment designed to promote bone in-growth.

Ti-LifeTECHNOLOGY allows to design devices featuring an overall reduced density to optimize the medical imaging performances and post-operative evaluations.

Ti-LifeTECHNOLOGY features a rough surface for primary stability within the endplates.
