Well the reasoning I heard was K2M was set to outpace stryker in spinal sales and stryker wasnt having that. Looks better to report a huge acquisition than you just got outpaced. However, this looks really similar to the spinal implant that ghosted and whent AWOL featured in that Amedica presentation as far as tech. from what I can tell.

The idea of a porous covered in a solid and machined to expose the porous. SiNi is extremely hard and difficult to machine, obviously. Especially with K2M previously in place here at AMDA.

what's causing the blackness in titanium K2M?

"uses an advanced 3D printing method" robocasting anyone?

"K2M’s Lamellar 3D Titanium Technology™" trademarked and proprietary.

Let's investigate the word Lamellar

"Lamellar structures or microstructures are composed of fine, alternating layers of different materials"

So how does one turn titanium black?

My guess is that it would be Black Titanium Nitride. After blowing the dust off a few memory cells, I thought it was in JCK that I some years back read about it so I found this link for you…

You can do this to some degree in house by heating and cooling the
Titanium… I used to know the entire method but the cobwebs are justtoo danged thick!!! I remember it took 2000 deg. F. or so to make ithappen… it was a tough process but I do remember getting some nice blacks and the surface was really really durable.

really really durable you say? Sounds like a possibility for the color we're seeing. let's push that through medical testing and see what can be found to back this up.

And boom. sounds about right. Perhaps K2M was a bunch of busters the entire time. constantly copping. Silicon Nitride is the only material that displays all of the characteristics in the same place so easily. It's not going to change no matter how hard they try to imitate and extract.
