It's also easy to see why the power tool industry resists the technology, William K. The idea of implementing this technology raises the possibility of having to invest gigantic amounts of capital to re-tool their existing production lines.

Even more than changing the production lines, that sawstop works at the expense of saw functionality. Consider that it stops the blade with a ridgid stop lever jammed into the swas teeth. So it does stop fast enough to prevent an injury , which is within one tooths distance on the blade. So the blade attachment may be damaged, and for sure the blade is sort of reshaped a bit, and that expensive stop actuator must be replaced, since the high presure charge has been used. So your saw is out of business until the expensive part is replaced. That may be OK for a home experimenor but it will be a big problem for folks using the saw for making a living. Then there is the question about what if you don't replace the driver, but instead just remove it. That means that you have defeated a safety device, and can be attacked by the OSHA man.

So while the sawstop is an interesting device, it is a big burden as well. Next question is how many folks do cut off fingers every year? Not that many, I don't think.

Re: Bone rasp or industrial tool?

78RPM, I agree about 3D printing making stuff that's too complex to do any other way. That's definitely one of its big draws. BTW, the photo in this story doesn't show the $70 titanium part that bone grows around; that's an acetabular cup. The photo shows a titanium bone rasp for hollowing out femurs, as the caption states.

Folks, the discussion here about SawStop potentially being applied to robots working with humans gave me an idea. Please check out this post about possibly starting a Design Ideas forum and tell us what you think: http://www.designnews.com/author.asp?section_id=1392&doc_id=259964

SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
A new thermoplastic composite for high-speed, high-volume injection molding has tensile strength that's close to, and sometimes better than, either lay-up composites or metals.
Lawrence Livermore National Laboratory and MIT have 3D-printed a new class of metamaterials that are both exceptionally light and have exceptional strength and stiffness. The new metamaterials maintain a nearly constant stiffness per unit of mass density, over three orders of magnitude.
Smart composites that let the material's structural health be monitored automatically and continuously are getting closer to reality. R&D partners in an EU-sponsored project have demonstrated what they say is the first complete, miniaturized, fiber-optic sensor system entirely embedded inside a fiber-reinforced composite.
The amount of plastic clogging the ocean continues to grow. Some startling, not-so-good news has come out recently about the roles plastic is playing in the ocean, as well as more heartening news about efforts to collect and reuse it.
