...and while a new 3D Printer is not news, I couldn't help but think back to the days when the only direct 'physical' output from a CAD system was a Drawing.
A standard part of virtually all CAD systems has been a 'plotter' so that Drawings could be 'printed'. Back in the early days of the CAD industry (I've been part of that history since 1977) plotters were large and often rather expensive pieces of equipment. When the company I worked for (back in Saginaw, MI) installed our first CAD/CAM system in 1977, included was what was then the cutting-edge in plotting, a Calcomp 960. Now this was an E-size, two-pen, belt-plotter which cost over $50K (and this was in 1977 dollars). Now that was a deal. Across town a the GM Steering Gear plant, they were using a Xynetics flatbed-plotter that cost them well over $100K and our Calcomp was much faster. However, they both suffered from the same inconvenience of having to clean pens, keep them filled with ink and if you needed more than two line widths, you had to change pens and re-plot, which was a real pain-in-the-###, but that was state-of-the-art at the time and still an amazing thing to watch your perfectly lettered Drawings being produced at the push of a button.
Well a few years later, after I had changed careers and went to work for McDonnell Douglas selling CAD systems, we were still limited pretty much that same pen-plotter technology. By then the large-format (D- and E-size) plotting was dominated by brands like Calcomp (Flatbed and Belt-plotters), Benson (Drum plotters), Xynetics (Flatbed), Gerber (Flatbed and Photo plotters), etc., all of them large and expensive.
Then in 1981 HP introduced the HP 7580. This was a D-size, eight-pen, so-called 'grit-wheel' plotter (that simply pinched the drawing sheet between a set of grit-wheels to move it thus eliminating the need to tape down your drawing sheet) which was very fast and cost less than $16K. Now it's true that HP had been in the plotter business for years, making smaller lab-sized X-Y plotters (I used them in college back in the late 60's early 70's), but when they moved into the full-size engineering drawing business, nothing was ever the same. And it wasn't just the price point, but also the shape factor and with the support for true multi-pen plotting it opened up things more use of colors and such. But one thing else it did was to make the technology more practical for everyone.
Case-in-point: When we sold our first CAD system with one of those new HP 7580 plotters I can remember when our installation group (remember in those days CAD systems were generally sold turn-key with CAD Terminals, CPU's, Disk Drives, Printers, Tape Decks, Paper-tape punches/readers, often digitizers and of course a plotter) calling up HP and asking when they could schedule a service tech to 'install' the plotter at the customers site (since this was the first HP plotter we had sold, our people had no experience with them). Anyway, the HP people thought it was a joke or something since all you had to do was plug it in, connect it to the CPU, turn it on and go. This was one of the first high-tech devices where the 'installation instructions' were what you'd call a sort of 'comic-book' like format with mostly pictures showing what plugged into what and almost no text whatsoever.
For anyone out there who doesn't gp back as far as I do in this industry, here's a few images of those original plotters we had to contend with:

Calcomp 960 belt-plotter

Xynetics flatbed-plotter

HP 7580B plotter
Anyway, the point I was trying to make is that perhaps HP will have the same effect on where 3D Printing is going as it did on Plotting. After all, anyone who can remember the early 3D Systems and Stratasys Stereolithography machines can see how these newer generation devices have already come a long ways and when someone as large and significant as HP, with their lonmg history of '2D printing' moves into the next 'dimension', well it will be fun to watch.

Seriously though I'm trying to work out what their technology is, from a few minutes looking on their site are they basically bonding the powdered material elements together?

"So parts are fused together at a very small level -- almost at the molecular level, and that helps give them a spectacular strength," said Alex Monino, HP 3D printing marketing director.
http://www.computerworld.com/article/3071035/emerg...
So 'almost' on the molecular level, except, you know, not nearly so.
Finally some technical notes, though:
So instead of the single nozzle printing back-and-forth line-by-line like most inkjet printers adapted to laying down the binder... it's using a lot of nozzles to 'carpet bomb' the powder with the binder in one pass. That's cool.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

I have not touched a large format plotter in probably 12 years.
Everything is saved as PDF and viewed on large monitors, then printed on 11x17 printers if needed.

Where I work now, a Stratasys has made its appearance, too. I've even had the opportunity to design & print a number of parts with it. I'm with you John; this will be fun to watch.

I'm sure HP is coming at this with the same disgusting "printer 'ink' selling company" mentality that they've created with inkjet printers. I know of no one that still buys HP printers because of HP's ink cost greed. I wonder how this general hatred for HP and it's printing supplies will carry over to their foray into 3D.

"You wouldn't want to void your warranty by contaminating your printer with non-brand feedstocks..."
"I see what your problem is sir; your account with HP is overdue this month, but once we resolve the issue I'm sure we can command the printer to start printing for you within one business day..."
...and so it goes.
Just being cynical.

Certainly if you were a professional whose performance depended upon keeping your machine running and -not- having to scrap a 30 hour job after 25 hours of run time, you'd not risk your reputation in efforts to pinch the pennies using recycled filament. The filament is not really that huge of an expense. Thus the recyclers, as mentioned, are hobby toys, for people who just like 'tinkering' and don't care about delays or down time.
Once you get to a certain scale of quality of filament production, then it's less 'recycling' and just "how you make plastic products" really.
There are some places we won't buy tool steel from, or at least, places we STRONGLY prefer to source tool steels from. This is because their product is a known quantity every time, and is dependable. No different.
RE: Will HP do for 3D Printing what they did for Pen Plotting back in the early 80's...
They claimed it had 21 micron resolution although I don't know if that was X-Y and/or Z. The parts they had on display looked pretty decent but they had some discontinuities at times that is common with some of the additive manufacturing methods. The claim they could print strain gages into the parts (in the future) was pretty sweet but still limited usefulness for me other than possibly augmenting our existing test equipment (e.g. building a product specific fixture that could measure loads alongside the load cell, or in a different orientation). HP claimed it was a collaborative project and so I got the impression there was some "open source" aspects that may or may not have included the build material, I can't recall. I'm not in the weeds on AM other than a bit on more medical oriented processes so take what you will with a grain of salt.
My company already has an older (but capable) Objet machine so I'm not sure how useful their new machines would be to us.

However, there are already a few niches where it comes into its own, as material properties, cost of ownership, speed of manufacture... improves and factors like 'use of resources' come into play that could change.

So, maybe in a decade or 2 it will be viable production method for a lot of consumer items etc. not just niches.
Especially if the facility to customize each build can be taken advantage of.

Continuing down that path will yield the result KENAT expects, I believe. That seems to be the way technology goes. First you start doing something brand new, but it's slow and expensive and it doesn't fit many situations at all. Then someone makes it either less slow or less expensive (one at a time) and it gains market share. Then someone fixes the neglected constraint and it becomes a new norm.

For aerospace etc. the ability to have parts that are almost hollow except for an internal latticework has major potential for instance.
In fact, it has major potential for my field, I just haven't been able to persuade anyone yet - and the available DMLS materials have some issues for us in other material property aspects.

I've read about some significant design changes that DMLS or SLS type processes have allowed. Speaking of KENAT's note toward hollow structures with intricate interior structures, this article from NASA comes to mind: http://www.nasa.gov/marshall/news/nasa-3-D-prints-...
With hints toward both cost reduction and performance improvement for a production mindset rather than one-offs or prototypes:
Obviously a niche outlier, but it is a proof of success/potential, certainly.
RE: Will HP do for 3D Printing what they did for Pen Plotting back in the early 80's...
Not everyone is trying to make 10,000 parts; I have more examples of <10 part runs than >10 part runs (okay, that's hyperbole, but it feels true). But up until recently even if I prototyped in DMLS I had to traditionally manufacture the parts released to the field (at horrendous cost)... but that's a regulatory story and I wont cry you a river. :)
