Of interest to all those working with "hot stuff".

Pax already has a good chunk of the source up in his github repositories: https://github.com/PaxInstruments

Gotta love open source hardware!
The Pax Instruments T400 is a simple, accurate, inexpensive, open source, four-channel temperature datalogger.

MakerBot's finally pulled the plug on the old Google Group.

gasp I'm shocked!  (said no one ;-)
Google Groups allows you to create and participate in online forums and email-based groups with a rich experience for community conversations.

Dunno what the positional accuracy is like, but if this is truly 0.1um resolution...  Back in '98 TSMC was just releasing their 0.18um CMOS process and MEMS was just starting to appear.

This is potentially MEMS-scale 3D printing! For $5K!

I saw it (not running). I can believe that they have .1um theoretical positioning accuracy (probably counting microstepping, which is not reliably precise). The Z screw had a pretty fine pitch, though looked like it might have been a 2-start. Believe that it had a full-step travel distance of (approximately) 3.2um, which would make each microstep nominally .1um. I only saw the Z screw, but the X and Y are probably running on the same thing. I don't believe that the laser is focused to selectively cure a point that small (if it was, the cured point wouldn't be fused together). It's probably curing an area significantly larger than that, with a theoretical (assuming microstepping is reliably precise, which it isn't) positioning accuracy of.1um, which is much less impressive than it sounds.

This could get interesting in the embedded computing space.
ARM has just purchased a gaming graphics technology outfit called Geomerics -- a name which may not ring a bell unless you're a particularly inquisitive

General discussion  - 
 
Some food for thought.

If we can find something similarly ancient to this Patent US3016451 in the patent system with a "quick release" mechanism, or manuals for 20+ year old products (or existing devices in museums) that have mechanisms to quickly disengage a filament from the drive system...

Since 20140120196 (http://www.freepatentsonline.com/y2014/0120196.html) specifies an "extruder assembly", something pre-existing for semi-automated, industrial hot-glue or thermoplastic dispensing should do the trick.  Kill the overly-broad independent claims 1 and 14 and the patent's effectively dead.

I don't read anything uniquely "three-dee-printing"  specific to it.  Any industry that uses tools that take a "filament" feedstock as input and passes it thru an "extruder" is likely to already have benefited from a quick-release mechanism to ease reloading.  The tricky bit is finding those examples and mapping each element in the patent's claims directly to (sub)system elements.

Disclaimer: I Am Not A Lawyer. ;-)

My hot melt glue guns are all extruders with screw off nozzles. Might be a patient on those.

Video for this "Wearable Futures" conference should be appearing on their YouTube channel over the next couple of days.  I only caught a few snippets of the live-streamed presentations, but they look to be very interesting.

Lots of 3DP content!
