From the site:
This project describes a design study for a core module on a NASA Lunar South Pole outpost, constructed by 3D printing technology with the use of in-situ resources and equipped with a bio-regenerative life support system. The module would be a hybrid of deployable (CLASS II) and in-situ built (CLASS III) structures. It would combine deployable membrane structures and pre-integrated rigid elements with a sintered regolith shell for enhanced radiation and micrometeorite shielding. The closed loop ecological system would support a sustainable presence on the Moon with particular focus on research activities.
The construction method for SinterHab is based on 3D printing by sintering of the lunar regolith. Sinterator robotics 3D printing technology proposed by NASA JPL enables construction of future generations of large lunar settlements with little imported material and the use of solar energy. The regolith is processed, placed and sintered by a the Sinterator robotics system which combines the NASA ATHLETE and the Chariot remotely controlled rovers. Microwave sintering creates a rigid structure in the form of walls, vaults and other architectural elements. The interior is coated with a layer of inflatable membranes inspired by the TransHab project.
Abstract from the project site:
3D printing technology is rapidly maturing and becoming ubiquitous. One of the remaining obstacles to wide-scale adoption is that the object to be printed must fit into the working volume of the 3D printer. We propose a framework, called Chopper, to decompose a large 3D object into smaller parts so that each part fits into the printing volume. These parts can then be assembled to form the original object. We formulate a number of desirable criteria for the partition, including assemblability, having few components, unobtrusiveness of the seams, and structural soundness. Chopper optimizes these criteria and generates a partition either automatically or with user guidance. Our prototype outputs the final decomposed parts with customized connectors on the interfaces. We demonstrate the effectiveness of Chopper on a variety of non-trivial real-world objects.You can find the paper, video and more details on:

The Printrbot jr. - TWO Printrbot jr. kits for $700. Keep one for yourself. GIVE one to a local school.
- Small. Folds up and fits in a backpack.
- Tiny Footprint. Sits easily on a desk.
- Light. 6 lbs. PLA. Uses biodegradable, non-toxic plastic.
- Batteries optional. Ships with off the shelf 12V power supply.
- Simple to build and operate.
So what can Willit 3D Print do?:
- Test if your part has features that can be 3D printed or not
- Visualise the surface roughness of the printed part
- See where support is needed
- Estimate the build time and the cost of your part
- Calculate the carbon footprint of your part
- Reorientate, rescale, and reposition your part
- Export your changes (in STL or AMF)
Update: I gave it a short test. In my latest version of Firefox it failed to load file, probably a bug on my side. It works perfectly in Chrome. It still needs more simulated printers and print materials. Great tool!

The Portabee has been the first conveniently portable 3D printer in the world. It is easily collapsible in a matter of seconds and fits into a laptop bag, making it transportable 'on-the-go' - bring it along with you when taking a bus, a train... even on a bicycle in a haversack on your back! And since it's lightweight - weighing in at 2.8kg (6.2lbs) - you can bring it around anywhere with you!
And with a slightly larger 'laptop luggage' style bag, you can put the Portabee into the same bag as your laptop computer, along with some feedstock filament, power supplies for both devices (the Portabee uses a laptop-type power supply), some instant coffee sachets, cookies... you get the idea.
The Portabee opens up numerous possibilities which were previously impractical - designers and design engineers can now offer to print out a sample of their design solution at the client's premises, on the spot and with applied design changes, for quick evaluation. Educators can loan Portabees to students for a time period to complete a school assignment involving 3D printing, be it an arts, design, or engineering discipline. An artist can walk into her favourite cafe, suddenly get in a creative mood, whip out the Portabee and a laptop and start designing something and print it out, all while sipping her usual cuppa and enjoying some cheesecake.
The Portabee is available as an unassembled kit form with a colour illustrated step-by-step assembly guide. Assembled and tested Portabee 3D Printers are also available.

From the video description:
This is an automatic transmission model I designed and 3D printed (you can download the design here: http://www.thingiverse.com/thing:34778). This type of gearing arrangement is common in automatic transmissions in cars, though the clutches and brakes and hydraulics that control them are far more complex than modeled here. Also missing is the torque converter.
These gears are known as herringbone, which are not generally found in real transmissions because they are too difficult to machine. However, they are easy to print, and they have the advantage of being self-centering.

The DIWire Bender is a rapid prototype machine that bends metal wire to produce 2D or 3D shapes.
Wire unwinds from a spool, passes through a series of wheels that straighten it, and then feeds through the bending head, which moves around in 3 dimensions to create the desired bends and curves. Vector files (e.g., Adobe Illustrator files), text files of commands (e.g., feed 50 mm, bend 90° to right…) provide DIWire’s instructions.
It’s essentially a 3D printer that describes lines, instead of volumes, in space, and it could be used for anything from prototypes to customized products.
Here is interview with the creator and more details on field use:

Main features from their Kickstarter page:
Injection-Molded Plastic PartsMore on:
All of the molded parts have molded-in inserts that eliminate a lot of complication and extra hardware (no nuts to tighten!). This allows the printer to be assembled quickly and provide consistency in manufacturing, making your printer more accurate.
New Head Design
We have taken components that we have liked from other designs and combined them to create our complete head design. The cold end and the hot end combine to make a functioning and simple to put together head.
A gear on rack design controls the movement in the x-axis; this means there are no belts or pulleys, simplifying the assembly as well as eliminating calibration.
A uniquely designed motor mount allows both sides of the motor to control movement in the Y-Axis. This ensures that the build tray will move evenly back and forth.
We use ACME threaded rods and screws with two nema 17 motors wired in parallel. One of the challenges is getting the Z-Axis to home to the build tray at the right level. We have designed a special clip that snaps onto the Z-Axis rod, which fixes this problem making it simple to calibrate.
Heated Build Tray
With a heated build tray, you can build PLA or ABS plastic without warping. It is very easy to level with four screws, one on each corner. Together with easy leveling and the Z-Axis clip you can have your build tray homed and leveled without getting frustrated.
Snap-in Roller Bearings
The L5 printer uses 12 roller bearings to give it the smoothest movement in the X Y and Z-axis.
We wanted a printer that not only prints well, but also looks great. A printer that would be a conversation piece that looked good on an office desk, in your home or at school. We went through many design iterations until we found a design we felt was clean and simple. A design that was inspired by speedboats and sexy cars.
