This is important step forward for the entire field: open source sub 1500 USD metal printer. It can be mad by anyone with some experience. It is based on static MIG welder and moving invert delta 3d printer platform as build bed.

Project was developed by Michigan Tech's Open Sustainability Technology Lab: Gerald C. Anzalone, Chenlong Zhang, Bas Wijnen, Paul G. Sanders and Joshua M. Pearce. Kudos to you gentlemen!


From project abstract:

Technical progress in the open-source self replicating rapid prototyper (RepRap) community has enabled a distributed form of additive manufacturing to expand rapidly using polymer-based materials. However, the lack of an open-source metal alternative and the high capital costs and slow throughput of proprietary commercialized metal 3-D printers has severely restricted their deployment. The applications of commercialized metal 3-D printers are limited to only rapid prototyping and expensive finished products. This severely restricts the access of the technology for small and medium enterprises, the developing world and for use in laboratories. This paper reports on the development of a <$2000 open-source metal 3-D printer. The metal 3-D printer is controlled with an open-source micro-controller and is a combination of a low-cost commercial gas-metal arc welder and a derivative of the Rostock, a deltabot RepRap. The bill of materials, electrical and mechanical design schematics, and basic construction and operating procedures are provided. A preliminary technical analysis of the properties of the 3-D printer and the resultant steel products are performed. The results of printing customized functional metal parts are discussed and conclusions are drawn about the potential for the technology and the future work necessary for the mass distribution of this technology.

There is another welder based DIY metal 3d printer project with almost no documentation - The Chipfuzer:

http://diy3dprinting.blogspot.com/2013/11/chipfuzer-diy-3d-metal-printer-by-mark.html

Mini Metal Maker is small DIY 3d printer that prints objects suitable for jewelry production, watchmaking and small gears modeling,  small pistons and generally small metal parts. It uses precious metal clay that needs to be put in a high temperature kiln in order to get into metallic form. it will not make "regular" sized hard metal parts. It is more oriented towards craftsman and artisans.

From the Mini Metal Maker page:

The impact



The Mini Metal Maker is a game-changer in the world of do-it-yourself 3-D printing. It gives engineers and designers a new tool for fabricating precision parts without expensive machinery or difficult manual processes. It puts a powerful new tool in the hands of artists and craftsmen for creating customized repeatable items in metal. It is also a valuable and accessible educational tool because it is low cost and small enough to be portable.

I've always dreamed of being able to print miniature parts and detailed sculptures directly in metal. To me, the Mini Metal Maker moves 3D printing from the land of plastic toys into the real world of arts, science, and engineering. I have had so much fun creating and using the Mini Metal Maker, and believe that you will too. 

Other Ways You Can Help

Your words are precious to us. If you can not contribute, or if you simply wish to help another way, please like us on Facebook, share our website with your friends, and spread the word about the Mini Metal Maker to anyone who might be interested.

FAQ
What is the Mini Metal Maker for?
The Mini Metal Maker is for printing custom jewelry such as rings and gem settings, sculptures, specialized machine parts, ornamental hardware, metal chains, or even special hardware such as miniature turbines or pistons.

Who will use the Mini Metal Maker?
The Mini Metal Maker is for anyone interested in creating small detailed metal objects. This includes the 3D Maker community and as jewelry artisans. The Mini Metal Maker is also a valuable tool for design engineers and machinists, who require small runs of specialized hardware for creating prototypes. The Mini Metal Maker adds new capability for the DIY inventor or artist by making fabrication in metal easy and direct.

What's the print bed size?
The print bed currently allows for prints up to 2.3 inches x 2.3 inches x 2.3 inches (6 cm x 6 cm x 6 cm) in size. The movement resolution is up to 1600 steps/mm.

How does the clay become metal?
The device prints with a commercially available jewelry product known as "metal clay." This material is a pre-mixed emulsion of metal particles in a water soluble organic binder. When heated in a kiln (600˚C-900˚C) the binder burns away as the metal particles fuse together.

Where can I buy materials for the printer?

I have been purchasing various metal clay materials online from Amazon and also through e-bay. The Mini Metal Maker requires the clay to be precisely mixed to a special consistency. I will provide pre-mixed syringes of clay along with the parts and software for the MiniMetalMaker.

Can I use it with other clays, or just metal clay?
The mini metal maker will work for most water soluble clay or ceramic type materials if the consistency of the material is properly mixed. Refining this mixing process for each of the available types of clay is an important part of the research and development we are currently completing. Since the device extrudes from commercially available syringes, it is entirely possible for users to develop their own clay blends. We will make pre-mixed clays of different varieties available for sale along with the Mini Metal Maker.

How big is the printer?

Our current printer measures 16 inches (41 cm) tall, 7 inches (18 cm) wide, and 12 inches (30 cm) deep. The new prototype will be slightly deeper in order to accommodate bed motion for two heads in place of just one.

Will it work with Windows 8? How about Macintosh?
Yes, and Yes. The core computer for the Mini Metal Maker is an Arduino Duo running modified Sprinter-based open source firmware. We are developing a cross-platform work environment for loading your objects into the printer.

Do you always need a computer to print?
No. It will be able to print directly from SD cards. Our current prototype requires a connection to a computer, but we are designing the production model to print directly from a compact flash chip that is inserted into the machine.

Does it work with a USB port?

Yes it does. It just has a standard printer-type USB cord that you could pull out of the back of your normal printer and connect to this printer.

Does it cause indoor air pollution or health problems for users?
No. The Mini Metal Maker does not cause any fumes or air pollution. The clay is water based and non-toxic, as its original purpose was for sculpting by hand. Also, the entire machine operates at room temperature because it does not have to melt plastic. You will need to purchase a small *kiln, however, in order to fire the objects.

*Kilns of any sort should be located in a well ventilated area away, often in a garage or a covered outdoor work area.

Another delta Kickstarter. BI v2.0 comes with some powerful features and affordable price.

From Kickstarter description:

The BI V2.0 capably produces very large 300 mm diameter X 300 mm height prints and features an amazing print quality (Be sure to read more about the definition of a true delta build volume below). Our design can support up to triple extrusion and can print virtually any 1.75 mm filament extruding at up to 240 degrees Celsius (PLA/ABS/Nylon etc.). The most unique aspect of the BI V2.0 is our innovative approach towards a self-replicating design which permits the simple creation of extremely precise movement. The end result: the highest standards of print quality. The self-replicating design of the BI V2.0 empowers you to create your own machine and share this technology with your family and friends. Once you receive the BI V2.0, you can print, improve upon and share components so that anyone can build their own printer at a very low cost.

Another Rostock derived Delta 3d printer with very detailed build guide.

From project page:

The MOST Delta printer is RepRap derived from the Rostock printer with the following design goals:

• Simple build process
• Safe to operate
• True to RepRap
• Maximize value
• Maximize rigidity
• Aesthetically pleasing (or at least neutral)
• All PLA printed parts
• Excellent print performance

The design utilizes plywood linking boards cut to a length that yields a desired printer radius when attached to the printed apexes. This simplifies assembly while helping to assure that printer dimensions are fixed, stable and reasonably well known. It also improves flexibility as the print area in the x-y plane can be changed simply by replacing the boards with boards of a different length. The delta design is inherently simpler to assemble as compared to virtually all it's Cartesian counterparts; this design can easily be built within a day by one person having properly prepared parts.
The design uses a 12v 5A power brick instead of the popular 12v power supplies having mains connections relatively exposed, a relative safety issue, particularly when children are present. The power supply is roughly equivalent to those found with many inkjet printers.
As many printed parts are used in the design as are practical, including printed pulleys. This in large part drove the decision to use open T5 timing belts for the drive, which also makes the design more flexible as the length of the guide rods doesn't need to be based upon the length of an off-the-shelf continuous belt.
Cost considerations drove decisions regarding everything from printer capabilities (as shown, prints PLA only) to guide rod material and length (two six foot lengths of 8mm drill steel are required, producing no waste). A Melzi controller is used as it provides all the necessary features as well as SD card support and reasonable expansion options. The power supply is a fraction of the cost of that required for powering a heated bed.
Printed apexes are very robust, probably overkill, and along with the plywood components and ample fasteners produce a very rigid structure. The printer has proven to transport very well (and can even be seat belted) with no adjustment needed prior to printing at its destination.
The end effector is actively cooled allowing for a unitized effector/hot end mount printed in PLA. The hot end is recessed within the end effector, maximizing z-axis travel and also providing for some print cooling.
Printing performance has been very good as has been the experience of printing with this design. Much less user intervention has been required as compared to experience with Cartesian RepRaps.

Printer capabilities/statistics

• Print media: PLA only (heated bed can be added, expanding media options)
• Filament diameter: 1.75mm
• Nozzle diameter: 0.5mm (can be changed)
• Print volume: ~250mm radius (with 240mm long linking boards) 270mm high
• Melzi print controller w/ integrated SD card reader
• Airtripper's Bowden Extruder

Update:

It is on Kickstarter now:

http://www.kickstarter.com/projects/1142241325/deltatrix-3d-printer-open-source-and-fully-hackabl


Technical specifications described in Kickstarter campaign:

The theoretical printing area is 280mm (11 inch) in diameter. As a square this works out as (almost) 200x200mm (8"x8"), which suits the used 'MK2A' heated bed. As it is also useful to be able to remove items, the gap between the uprights is just over 295mm. The maximum build height is around 280mm (11").
Main features:

• Linear delta robot layout provides a mechanically simple motion platform for moving the print head only, not the workpiece.

• Off the shelf RAMPS electronics allow for easy replacement in case things go wrong.

• Using a LCD display and SD memory card (supplied in our kits), the DeltaTrix 3D Printer can operate on it's own. It does not need to be attached to a computer.

• There are several (Open Source) options in terms of software. At the moment we are using Repetier on the PC, a modified version of Marlin as the firmware on the RAMPS electronics, and the standard Arduino IDE for tweaking the firmware.

• A heated bed with glass print surface, allows for PLA and ABS to be used as filament.

• In terms of filament, the DeltaTrix 3D Printer is designed to accept 1.75mm PLA and ABS on a variety of 1kg reels, as long as it is of good quality.

• Igus linear slides with pretension are used, providing a robust and durable bearing solution from a highly reputable manufacturer. The strengthening ribs on the uprights keep the rails straight and sturdy.

• The current design print head assembly uses a single Reprappro Hot End, with a nozzle size of 0.3 or 0.5mm. The assembly also has a fan and integrated duct for cooling the top of a print.

• Quick changeover print head assembly. Useful for swapping between two print head assemblies, eg. one for ABS and one for PLA. The prototypes use connection blocks, but the kit will have proper connectors. Please, note: the standard kit only contains parts for one off print head assembly.

Theta printer has unique design, you can check the first post about it here:

From video description:

Testing the new firmware by printing an octopus. This print took about 1.5 hours with a feedrate of 20 °/s. In this case, thats roughly 55 mm/s. This printer should be capable of at least 40 °/s.

Very detailed information with full build instructions and all the files:

http://www.instructables.com/id/Geoweaver-Walking-3D-Printing-Hexapod/?ALLSTEPS

From Instructables description:

Geoweaver is a student designed robot created in the Creative Architecture Machines advanced options studio at the California College of the Arts (CCA) in San Francisco, California, taught by Jason Kelly Johnson of Future Cities Lab and Michael Shiloh. The design is based on a 12-servo hexapod with a glue gun extruder attached, and is the culmination of about 60 days of research and prototyping. Although the robot's official name is Geoweaver, it also goes by many aliases: Servo Killer, Eater of Shields, Melter of Wires, and Destroyer of Regulators, among many others. It is a very difficult and delicate machine, and is not a project to be tackled for the faint of heart.
But if you do take it upon yourself to accept it's challenges, it's rewards are great: it is a six-legged, walking 3D printer. The center mechanism uses two servos to control the pendulum-like extruder head, allowing it to cover a basic XY plane (though curved to the surface of a sphere, see video above), and one servo for the extrusion gear that forces the glue-sticks through the "print head." All of this can be controlled through the software Rhino 5, with the plug-ins Grasshopper and Firefly

it was designed and made by Student Team: Jia Wu, Jeffrey M. Maeshiro, Mary H. Sek at CCA - California College of the Arts Architecture Advanced Options Studio, Prof. Jason Kelly Johnson with Michael Shiloh

• New 32-bit Arduino-compatible Duet electronics enable control via a web-browser
• Wiring loom for simple plug-in connection – no soldering
• IR probing for self-aligned printing – no bed adjustment required
• Build volume: 210x190x140mm 
• Overall size: 500x460x410mm
• Printing materials: ABS, PLA, 1.75mm diameter thermoplastic.
• Build surface: PCB-heated bed to reduce complexity of assembly and to ensure parts do not warp.
• Computer interface: USB
• X-carriage: Three Z-adjustable deposition head mounts; one head supplied.
• Standard nozzle size: 0.5mm
• Accuracy: 0.1mm*
• Resolution: 0.0125mm*
• Building speed: 1,800 mm/min
• Moving speed: 12,000 mm/min
• Deposition rate: 33 cm3 / hr

*The resolution is how fine a step the motors can make. The accuracy is how accurately the machine can position things. So the resolution is finer than the accuracy because the accuracy is influenced by other factors, for example how well the timing belt is manufactured.

There is unclarity on build size since there are two sizes mentioned: 210x190x140mm (on RS page) and 200X200X200 (on RepRapPro description).

MadMaxx made this great video describing his experiences with Prusa Mendel. Because he described several problems and raised some questions he received a lot of negative comments on this video.
He did told me on twitter that he was intentionally controversial to start the debate which is important for open source community. Without discussion there is no progress and that is the point that some of his commentators do not understand. They just went into attack mode "HOW DARE YOU TALK ABOUT PROBLEMS!!!!!.




Problems he describes:

1. Hanging Z-axis
2. Two Z-axis motors
3. Lots of wire strain
4. Hard to maintain - easy to mess up 
5. X axis wobble

I don't't have lot of experience with Prusa Mendel, but I read or heard about most of those problems, but never tough of them as design issues. I just never connected the dots.
Many of those problems can be solved with upgrades and later Prusa Mendel designs made improvements to address those issues. And there is the Prusa I3 :-)

Update (11.1.2014.):

Josef Prusa responded to this video:

Hi man,
first, my name is pronounced "proosha".
As you said, its old model, no reason to bitch about it in 2013 you are three years too late ;-)
It is still built as there are thousands of ppl who can help you with it.

Hanging Z axis was made because it transfers less wobble to the print, now with tube couplings, its not needed. Your coupling slid out of the shafts either because they were oversized or you didnt tighten them. Sanding the motor shafts helps a lot too. Your cables broke as you didn't bolt them to the Y carriage or used poor cables. Two motor Z axis is much easier to maintain then the original mendel one, if you would built original mendel, you would know. That thing sucked to calibrate. The x axis wobble is true, but during prints it wasn't affecting the quality too much. ...
Anyway, keep up the good work.

Let's talk abut problems. Criticism is free consulting.

Here are videos by Allen Jetter that describe how he improved his Prusa Mendel and changes / upgrades he made. He invested lot of work and time. It doesn't solve all problems mentioned above and raises some new issues, but it is good illustration on hove to move ahead.

Wood is very cheap. Wood is easy to obtain. Wood is easy to work with and many shaping technologies are available. It comes in many forms with different properties from flexibility to strength. It is renewable resource. It can be easily recycled.
There were entire generations of printers like Ultimaker based on laser cut plywood, but full wood was never in fashion. probably because it is not high-tech and not self-replicating.
I would like to see more projects with wooden parts. I like the texture and natural aesthetics of wood contrasted to technology.

Here are some designs that use wooden parts, some are fully functional, some are under development:

Wood frame Mendel90

Mendel90 is great design and it is often built with wooden frame. One of the great success stories with wooden parts. Design is custimizable based on your input and generates paper printable cutting and drilling guides for the frame.

Adapto 3d printer

It can have aluminum beams and low cost wood frame.

Ikea RepRap

While surfing around I found this reprap with wooden / particleboard frame (maybe made from Ikea furniture). Further information is unavailable. Let me know if you have any additional information about this printer.

Gunstrap

The Gunstrap is a plywood repstrap that is based on the Mantis CNC design. It has a build area of 200x200x100mm (comparable to the Mendel) and is employs a heated build platform and a heated build chamber. Unlike other wood based repstrap's, no ball bearings are required for its construction, excluding the extruder and all parts can be obtained from scrapped printers and scanners. In addition, its build chamber can be heated up to 100 degrees Celsius as most stepper motors are contained out side of the build chamber and no thermoplastic is used in its construction. The only stepper motor within the build chamber is the extruder stepper motor which is actively cooled using a peltier.
