Today we’re on the verge of a factory in every home thanks to the RepRap, an open hardware 3D printer that is designed to replicate itself. You can make a RepRap for yourself, then use it to make one for your neighbor. The design files and software needed to build and operate the RepRap are free. You can make one for about $500 in parts. And with each new version of the machine, an increasing percentage of the parts can be produced by the RepRap itself.

This is the next step in my attempt to make a Sarrus linkage based 3D printer. The idea is to have a cartesian mechanism without those long rods and bearings.
I built three of the Mark III and mounted them in a x-y arrangement as shown. They can move over a square about 105 mm wide, and someday may carry an extruder. They are driven by DC motors taken from inkjet printers. These motors are driven in a servo arrangement using quadrature optical encoders and optical strips removed from the same printers.

Today Stratasys, the company that is manufacturing the device for HP, announced that it has shipped the first units of the HP-branded Designjet 3D fabrication machines, which will be available in May — but only in Europe.
The Designjet 3D is based on Stratasys’s Fused Deposition Modeling (FDM) technology, which turns three-dimensional CAD drawings into tangible prototypes by extruding partially molten ABS plastic in extremely fine layers one atop the other, forming the entire 3-D model in a single piece from the ground up.
Designjet 3D will print in ivory-colored plastic only while Designjet Color 3D will print single-color parts in up to eight different colors.
Future astronauts might end up living in a moon base created largely from lunar dust and regolith, if a giant 3-D printing device can work on the lunar surface.
The print-on-demand technology, known as D-Shape, could save on launch and transportation costs for manned missions to the moon. But the concept must first prove itself in exploratory tests funded by the European Space Agency (ESA)

It is early days yet but the first iteration of Kris Reed’s actuated robot arm looks very promising.
You can check out Kris’ blog post on how he came to make his arm here or see the 3D printed robot arm that will one day subjugate humanity in action below.

[...] The printer, developed by Invetech, fits inside a standard biosafety cabinet for sterile use. It includes two print heads, one for placing human cells, and the other for placing a hydrogel, scaffold, or support matrix.
Invetech plan to ship a number of 3D bio-printers to Organovo during 2010 and 2011 as a part of the instrument development program. Organovo will be placing the printers globally with researchers in centers of excellence for medical research.
from R&D Magazine:
“Scientists and engineers can use the 3-D bio printers to enable placing cells of almost any type into a desired pattern in 3-D,” said Murphy.
[...] Ultimately the idea would be for surgeons to have tissue on demand for various uses, and the best way to do that is get a number of bio-printers into the hands of researchers and give them the ability to make three dimensional tissues on demand.”
