Someone note in the comments that this is a CNC router. So, what is a different between CNC mill and CNC router?

"A CNC router will usually have a large X and Y range and short Z... A router will typically be able to do soft materials like wood, plastic, and maybe aluminum... But overall, it won't have the most rigid structure (like this one which is 3d printed)

A CNC Mill will have a relatively smaller X and Y with a larger Z than a router... A mill will be able to cut hard materials like steel... And thus will have a very rigid structure so that it can accurately cut those materials."

Laser Engraver from Discarded DVD Drives with 3D printed Frame

If you have few old DVD drives and an Arduino Uno you can make a simple laser engraver for some 15 USD. The supporting frame can be 3d printed or made from any material you can hack.

Here is the video of the same design with standard frame:

Iteration and Repair of Existing 3d Printed Objects Without Re-printing

I have seen the future! Changing already 3d printed objects without the need to 3d print them again! Group of researchers developed this method that uses multifinctional 3d printer with laser 3d scanner and CNC milling head to make changes to the already 3d printed object to add or subtract from the previous design.

You can also repair failed prints and make changes on the fly. The developers call this system "Patching". It saves a lot of time and material. Imagine spending few minutes repairing object that would take hours to reprint!

Seeing it in action is very impressive:

Hopefully this technique will find wider application and adoption on mainstream machines and design/control software.

Project description:

Personal fabrication is currently a one-way process: Once an object has been fabricated with a 3D printer, it cannot be changed anymore; any change requires printing a new version from scratch. In this paper, we propose a different approach: instead of re-printing the entire object from scratch, we suggest patching the existing object and replacing only the unsatisfactory parts. This saves material and reduces waste, making a first step towards more sustainable 3D printing.

This project is a collaboration between Hasso Plattner Institute and Cornell University.

How to Make a Concrete 3D Printer

Muhleman developed a concrete powder bed 3d printer that uses hacked Shapeoko CNC router mechanism.

It uses sand and cement mixture and a liquid soil hardener called polypavement as binding agent. Powder bed is loaded manually :-) but a mechanism could be developed in the futre.
Printed objects are rough but the concept is interesting for artistic purposes and concrete furniture where you can get more complex organic forms.

From DIY 3d printing history 5 - Early days of house printers

As far as I remember first time I saw house 3d printer was with Enrico Dinis D-shape.

PDF presentation:

http://www.d-shape.com/d_shape_presentation.pdf

... some CNC sites named it the house CNC router: http://www.bg-cnc.com/wordpress/?p=592

But even in earlier times, 1940ies, machines existed to make houses by direct deposit of cement mixture. Sure, they used big cement mold but it was probably the birth of an idea.

Hacking and Upgrading Cheap Chinese 3020 and 3040 CNCs

I plan to buy a cheap or even second-hand Chinese 3020 or 3040 CNC mill so I looked around to find a way to improve it with parts I already have like Arduino or some simple electronic upgrades. I found two interesting guides:

Upgrading 3020 (and other models) with Arduino, GRBL and CNC Shield V3

Detailed guide by EricAusome can be found at:

FlatFab software lets you design in 2d surfaces to make 3d objects for CNC cutting

FlatFab is a new CAD software that lets you intuitively design with two dimensional surfaces which you can then combine in 3d objects. It looks ideal for designing furniture or objects for CNC cutting.

I'm really getting interested in CNC cutting and milling since you can make larger functional objects like furniture from cheap materials like plywood.

Here is a simple FlatFab tutorial:

FlatFab homepage where you can download the software: http://flatfab.com/

There is no information on price or open source availability. It looks like it is in early stages of development so new features and improvements can be expected. It is available for Windows, Mac and Linux.

Update:

Here is a response from FlatFab team member:

"hi, flatfab is not open source at the moment, but it is FREE, and we intend to keep it that way. we also plan to grow with our user community so try it out and keep your feature requests coming."

Nice job FlatFab!

Ghost Gunner is a desktop weapon making CNC that will raise a lot of controversy and fear mongering

Defense Distributed know for their work on 3d printed guns released the Ghost Gunner. It is a small simplified desktop CNC machine that can finish a specific type of metal gun receiver. The controversy is that the receiver is the only gun part that is tracked in USA. Other parts to finish the complete gun one can purchase freely in the USA. Media is already hyping this news as "machine that is producing METAL guns untraceable by law enforcement". So few things to consider before panicking:

Everything this machine does can be made by hand easily with simple power tools
The machine development is closely linked to USA law and gun part market, since other countries have different definitions of what a traceable gun part is.
A change in the law, for example: making gun barrels traceable also can make it completely obsolete. Granted, someone can then develop open source gun barrel maker (which is much more complex then this CNC) ... even so, most of countries have much stricter gun laws then USA
CNC machines that can perform all this functions are available on the market for decades with slightly higher prices (which will drop in the future anyway)

It will be interesting to watch how this technology develops in the future and how will the lawmakers and media react to it. It will be also interesting to see how will the usage scenarios develop.
This machine makes only one thing now from semi-finished aluminum object, but it looks like it could be programmed to make other designs so DIY gunsmithing ecosystem could emerge.

Ghost Gunner technical specifications:

Machinable dimensions: 175 x 75 x 60mm (~6.75 x 2.95 x 2.35")
Maximum part dimensions: 230 x 90 x 100mm (~9.05 x 3.50 x 3.90")
Overall footprint: 330 x 280mm (~13 x 11")
Weight: 20kg (~45 pounds)
Spindle Speed: 10,000+ RPM (Final Value TBD)
Requirements: Windows 7 or higher. Mac version TBD.
Price: in 1199 USD range

About Ghost Gunner from their page:

Ghost Gunner is a non-profit open source hardware effort by Defense Distributed. Ghost Gunner builds on the open source community's existing hard work, including the gshield 3 axis motion hardware, the grbl g-code parser and motion controller, and the legendary Arduino microcontroller. All GhostGunner schematics and design files will be published into the public domain. Defense Distributed decided to build our own machine from the ground up. We found existing CNC machines too expensive, too DIY, or too inaccurate to manufacture firearms for the casual user. By miniaturizing the build envelope to just large enough to mill common firearm receivers, we were able to improve rigidity, reduce material cost and simultaneously relax some design limits, allowing us to sell an inexpensive machine with more than enough accuracy to manufacture firearms.

Ghost Gunner has undergone several design revisions to reduce machine chatter, backlash, and jitter, all with the goal of keeping total design cost low. Rather than using plastic, wood, or even an aluminum frame, Ghost Gunner is constructed with maximally rigid plasma-cut A36 steel and 304 stainless steel. In addition, the machine part count is greatly reduced compared to a traditional CNC, which both increases rigidity and further decreases cost. The end result is a small, cheap, and simple machine that exceeds most consumer-priced CNC machine specifications.

Ghost Gunner is a miniature CNC machine designed to automatically manufacture publicy created designs with nearly zero user interaction. No prior CNC knowledge or experience is required to manufacture from design files. Defense Distributed's first design is the venerable AR-15 lower receiver. Ghost Gunner automatically finds and aligns your 80% lower receiver to the machine, with simple installation instructions, point and click software and all required tools. Just follow a few simple instructions to mount your 80% lower receiver, tighten a couple screws (with simple tools we provide), and on day one, Ghost Gunner can help you legally manufacture unserialized firearms in the comfort of your own home.

As shipped, Ghost Gunner can manufacture any mil-spec 80% AR-15 lower receiver that already has the rear take down well milled out. Lowers with non-mil-spec trigger guards that are otherwise mil-spec are also compatible.

Ghost Gunner is capable of manufacturing more than just firearm receivers. With Defense Distributed's open source Physibles Development SDK (pDev), designers can distribute files via our '.dd' file format, which contains all installation and assembly instructions, any required jig files to hold the part in place (that users can print with a 3D printer), and all machine definitions and code to physically manufacture a particular design.
To a casual user, the .dd file is a one-stop solution to manufacturing any aluminum physible that the public can design to fit into the build envelope. Defense Distributed will be developing in and supporting this format, and we are happy to publish your own innovations and contributions.

Jon's homemade CNC router converted into DIY 3d printer

If you want to see another homemade CNC machine converted to 3d printer go and see Jon's project

http://www.jonshobbies.com/convert-a-cnc-router-to-a-3d-printer.html

He still controls this cnc 3d printer with Mach3 software. Since it has heavy aluminum gantry and was designed for routing, it is lot slower when 3d printing.

Here is his machine in action printing a whistle:
