How durable are things like this? I know virtually nothing about 3D printing. How tough can items be made?

3D-printing ranges from fragile resin pieces to metal durable enough to use as rocket nozzles. This article was about 3D printed titanium, so the resulting piece is likely stronger than bone but weaker than machined titanium would be.

The article says it’s titanium This is just “manufacturing” which has little resemblance to the consumer makerbot products

Hmm sure but it’s still 3D printing? It’s hard to imagine a conventional CNC machine doing this.

But then again I know nothing about CNC machines.

This is pretty awesome. And sure, right now it's limited to high end tech at the bleeding edge of medicine, but I fully hope this will inspire the current gen owners of glowforges, makerbots, xcarves, and all of their off-brand alternatives to begin making over-engineered, novel, and interesting finger splints or Band-Aids or other diy-friendly med tech.

I have a friend whose son was born with a partial hand. They were able to use 3D printing to make a prosthetic that was cheap enough they could make new ones as he grew. IIRC, they could do themes such as iron man for the prosthetic.

That’s super cool

There's a common issue with slipped discs and terrible long term pain. If the day comes when we can print and install new vertebrae easily, I'm signing up. I imagine in this world of phone and PC usage, there'll be many customers in the years to come.

3D printing metal is usually done by sintering a metal powder. The technology is good enough for turbine blades in aircraft engines.

Turbine blades in modern aircraft are gamma-TiAl, which is a single crystal. These are not 3d printed and the process for making them is similar but more advanced than making silicon wafers.

This is a decent documentary on Rolls Royce that discusses the single crystal blade. I think each one has 18 tons of centrifugal force, and uses a few micron layer of air to cool it, so running an engine too slow will melt them. Fascinating stuff.

Worth noting then that many already have been inspired :) http://www.openhandproject.org https://3dprint.nih.gov/collections/prosthetics

Me too. I suffer from degenerative discs, bone spurs and arthritis in all of my cervical and thoracic vertebrae. I'm in constant pain and if there was a realistic spinal replacement procedure, I would seriously consider it.

I don't know what caused my problems, but arthritis and bonr spurs definitely run in my family and 3 decades of poor posture haven't helped and ive had too numerous bicycle falls and car crashes over the years to even count (I was in a car accident just last week! Not my fault).

Some components with complex overhangs and voids can be impossible to mill with a CNC. A sintering 3D printer isn't constrained in that regard, and can make arbitrarily complex geometry without sacrificing precision.
