A self-replicating, open-source home factory

from sharable.net:

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.

HP Designjet 3D printer now on sale in Europe

from PopSci:

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.

3-D printing device could build Moon base from lunar dust and regolith

from Space.com:

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.

More details on Invetech & printing 3D body parts

from Next Big Future: <- [Much more at link]

[...] 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.

First commercial 3-D bio-printer makes human tissue and organs

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.”

Could 3D printing be the next revolution in cooking?

from Gizmag:

Wouldn’t it be great to have a digital food machine sitting in your kitchen that could create any dish, real or imagined, from scratch at the touch of a button?

Cornucopia: Digital Gastronomy is a concept design that uses the well-established principles of 3D printing – plus precisely timed and temperature-controlled mixing and cooking – to open the door to a virtually limitless realm of replicable, creative cuisine in shapes and combinations that are simply impossible using our current, centuries-old cooking techniques. It’s a wonderful look into the future of cooking, from the creative food lover’s perspective.

HP plans a line of (relatively) affordable 3-D printers

from GadgetLab:

Printers equipped for 3-D are poised to go mainstream, now that Hewlett-Packard plans to start selling them. The company’s inkjet and laser printers are staples in offices and homes.

The devices, which can crank out three-dimensional plastic models through a process similar to printing text on sheets of paper, have until recently been available only to high-end industrial designers. HP’s devices will be targeted at a broader market of mechanical-design professionals, and will probably cost less than $15,000.

“This is the boldest step we have seen so far in 3-D printing,” says Scott Summit, chief technology officer for Bespoke Innovations, a company that creates 3-D artifacts for medical use. “A lot of people want to do 3-D printing but it is a mysterious world. With HP embracing it, it is likely to demystify the idea to many consumers.”

3-D printers can take blobs of plastic and shape them into almost any object you desire. Now, thanks to open source hardware designs and enthusiastic do-it-yourselfers, these printers are increasingly popular and accessible. People are using them to fabricate iPod docks, plastic bracelets, hair clips and miniature teapots at home.
