I hope his project will be successful and well documented!

Many people are building machines they designed from scratch. Here is combination of CNC machine and 3d printer which is well documented with complete build guide. It has some interesting features like printing with many materials.

Here is 2BEIGH3 as CNC cutter slicing trough acrylic plate:



Here is 2BEIGH3 3d printing with Nylon (btw: printing Nylon emits toxic fumes, it should be done in controlled environment):

2BEIGH3 technical specifications:

This is not your Prusa Mendel. This is the Godzilla of advanced industrial 3d printers, a hybrid metal laser sintering and high precision milling machine.
It can produce highly precise medical and dental implants and high end custom aerospace industry parts. The structures can have intricate internal structure that can decrease weight, improve cooling or add advanced structural properties.
Lumex Avance can also print complex molds and casts with integrated cooling for high cycle injection molding.
Typically, milling produces debris, or chips, of removed material that vary in size. However, the LUMEX machine utilizes dry cutting, meaning no coolant is used. For this reason, the cutters are very small and the machining metal removal is a fine powder. Thus, the porosity is theoretically equal to the particle size of the powder and gets incorporated into the powder mix. Usually, no removal of milling chips is needed.

MTM Multifab is truly multifunctional desktop manufacturing machine that was very innovative and ground breaking in the field of  DIY 3d printing when it was developed. Ultimaker, very well known and powerful 3d printer,  is based on this machine.
Multifab has several replaceable tool head options:

• MACHINING SPINDLE, A high-speed (20K RPM) spindle supports light subtractive machining. The spindle can be constructed entirely from off-the-shelf compoents.
• VINYL CUTTER, A razor blade tool which allows 2D cutting of sheet material. Some applications are flexible circuit boards, stickers, silkscreen masks, and more.
• REPEATING PIPETTER, This fluid dispensing toolhead was created in collaboration with MIT's Innovations in International Health program, and has uses in automated biology research and disease diagnostics fabrication.
• PLOTTER HEAD, A pen attached to the multifab can allow easy labeling of objects, caligraphy, etc...
• 5 AXIS TRUNNION, This attachment permits 5-axis machining of components on the Multifab. Potential applications include variabl-helix screws, impellers, and 5-sided machining operations.
• PLASTIC EXTRUDER, Based on the Rep-Rap project, this extrusion head will enable additive manufacturing in plastics such as ABS.

MTM Multifab 3d printing

Here are some videos of Multifab in action writing and pipettering:





Demonstration of the MTM Multifab fitted with an auto-pipetting toolhead. The toolhead was designed with Amber Houghstow and Jose Gomez-Marquez of the MIT Innovations in International Health program, with the goal of automating production of XoutTB diagnostic assays. Perhaps it can also find a use in the DIY Bio community.
The MTM Multifab is part of the MIT Center for Bits and Atoms Machines That Make project.

Here is overview of Multifabs components, tools and development status:


http://mtm.cba.mit.edu/fabinabox/devmultifab.html

The instructions, plans and BOMs should be available for anyone who wants to build it, but all the files and documents links I tried on the site were broken. I hope it will be repaired soon, the public could benefit greatly with this machine.

Fab-in-a-Box

The Multifab is core machine of FAB in a Box framework system that should provide full digital fabrication environment that user could make at their home from simple parts. It contains:

Infrastructure. All of the key services which allow Fab-in-a-Box to be a cohesive toolset. These include the network, the box itself, power distribution, etc. It consist of the:

1. VIRTUAL MACHINE ENVIRONMENT, The flexible Fab-in-a-Box machine control and interface environment.  
2. THE NETWORK: FABNET, An RS485-based network is the nervous system of the toolset, which connects the "brain" - a laptop running control software - to the tools and sensors comprising Fab-in-a-Box. 
3. THE SUITCASE, The suitcase is the heart of the matter. It is what contains the entire fab in a box project.

Multifab. A computer-controlled multipurpose fabrication tool. Work includes integration into the box, the xyz motion stage, and multiple toolheads to perform various fabrication tasks. Multifab has many subsystems, components and parts:

Other Fab. All other tools needed to make something. Examples are the soldering iron, hand tools, and programming interfaces.

Measurement. Networked instrumentation such as a multimeter and oscilloscope. This is one area which will hopefully expand greatly on the road.

1. MULTIMETER, A multimeter which displays and records its readings on the Fab-in-a-Box laptop.
2. OSCILLOSCOPE, An oscilloscope which displays and records its readings on the Fab-in-a-Box laptop.

Autodoc. Everything related to making it possible to document a project "without thought".

1. EYE-FI CAMERA, A camera which wirelessly tranfers its time-stamped images to the Fab-in-a-Box auto-documentation software.
2. RFID READER, Keeping track of which hand tools were used, and when, is made easy with an RFID reader.

Some of the components were never developed, and most of the building related file links can not be opened. Probably all the files are somewhere on the internet, it would be terrible if they get lost forever. I REALLY hope someone publishes them as open source soon.

PDF presentation:

http://mtm.cba.mit.edu/fabinabox/fabinabox.pdf

Must-watch video if you are interested into DIY, desktop manufacturing machines, hacking, making and generally awesome stuff!

Nadya Peek speaks about the process and basics of making machines that make, technology, digital fabrication economics, MIT modern high-end CNC machines and their limitations, how g-code is very stupid  and how biologists buy expensive machines that are easy and cheap to DIY ...
She also talks and shows many interesting machines that you can make yourself like liquid transfer and auto pipetting machines...



From video description:

Making a new control system for a machine is often a slow and tedious task. Maybe you already have a 3 axis stage, and you already know how to move it around. But what if you want to add a camera and use it for position feedback? You'd have to redesign the whole hardware layer.

I'll talk about some ways I've built modularity into control systems for machines so that you can quickly iterate on different kinds of machine systems without getting stuck in hardware land forever. This includes connecting synchronized nodes across a network and importing legacy nodes for things like, say, an old pressure box you found in the trash and has rs232 in.

Down with gcode! Long live machine control.

I found one of her presentations which loosely follows the theme of the talk in PDF format:

http://cba.mit.edu/events/13.03.scifab/Peek.pdf

She also spoke about some high end CNC machines being monitored by gyroscope, sensors and GPS so they can not be moved without authorization to prevent them begin exported to blacklisted countries. Here you can see the perfect example of that crazy security policy: http://boingboing.net/2014/01/06/high-end-cnc-machines-cant-b.html


The talk was part of 30th Chaos Communication Congress (30c3) by the Chaos Computer Club (CCC) at Congress Centrum Hamburg (CCH)

Another way to use high-end CNC machine as (low end) simple 3d printer. This project is done by Chin-Kai Chang, Rand Voorhies and Lior Elazary at University of Southern California(USC) iLab. ilab.usc.edu.
Personally, I don't think it makes much sense to do it in their setup with this big expensive CNC, but maybe someone will find a use for their hack.

From project description:

This is a in progress project that we try to use convention CNC mill/router as a 3D printer. Here, we use Mach3 control software which reads g-code and control the CNC movement. In this setup, we don't need to change the original setup and be able to switch CNC/printing jobs easily.

Here is a post about Mach3 software addon that enables it to to all the 3d printing required processing and slicing inside the program:

http://diy3dprinting.blogspot.com/2014/01/turn-your-cnc-into-3d-printer-with-add.html

Details and downloads:

http://www.thingiverse.com/thing:5233

Instructions from the Thingiverse:

1. Printer Head mount:
We choose Makerbot Plastruder MK5(http://www.thingiverse.com/thing:3290) as our print head. The mount plate and MK5 model can be found at thingiverse.com/thing:5221
2. Reprogram extruder controller board:
In our version of firmware, we implemented a simple serial protocol that takes a serial command to set/read temperature and control DC motor speed.
For example, send "T220" to set temperature to 220C and send "M255" to set motor pwm to 255. Send "R" to read current temperature and so on.
In addition, we also use one digital I/O pin(D9) as motor start/stop input which will connect to the computer parallel port used by Mach3. You can find the firmware in download section(iLabProto.pde)
3.Create the Mach3 setting file. We create a new Mach3 setting file named "PCNC770M3_Metric_3DP.xml" which is a copy from original CNC setup. Also, we add a new macros folder "PCNC770M3_Metric_3DP" under "C:_Mach3_macros" with all the extruder related M-code(M101,M103,M104,M108,M113,M200,M201,M5) that will generate from skeinforge.
In each M-code .m1s file , it looks like:
==================================
'M104 Macro Setting the temperature
Dim P
Dim Q
Dim R
Dim Temp as integer
P=Param1()
Q=Param2()
R=Param3()
Temp = R
Message("Setting Temp to " & Temp)
Call SendSerial ("T" & Temp & chr(13))
==================================
This allows Mach3 send serial command and talk to Extruder

4.Setup Mach3 serial and parallel connection to extruder controller board.

The idea to have both serial and parallel connection is because we assume there will be some latency of serial command in Mach3. So, we use the serial to set target temperature(M104) and motor speed(M108 because this command does not require very precise timing. Then, we use the parallel port to control the feeder to start/stop(M101/M103) as this command needs to run very fast.
In the serial connection, we need to remove the green pin(RTS#) because when Mach3 try to send a serial command, it will also sent a reset signal which cause extruder MCU to reset and lost all current temp/motor setting. In this way, we can even use a serial terminal to check/set other status when Mach3 is running but not sending any serial command.
Here, we hack the coolant pump signal(M8/M9) to replace our Motor start/stop command(M101/M103). We will replace all M101/M103 words to M8/M9 in the g-code later.
5.Generate the g-code from ReplicatorG, as a normal 3D printing procedure. We choose "Cupcake Basic" as our machine driver.
6.Run gcode-clean.pl perl script to create Mach3 usable code.
Even we had implemented all the M-code in Mach3, the g-code still not able to run under Mach3 and requires some adjustment.

First, Mach3 doesn't use "S" word in M code because it conflicts with spindle speed code. So, we need to replace all "S" word to "R" word. For example "M108 S220" becomes "M108 R220".
Second, skeinforge will generate G1 code with "X Y Z F" in each single line. This will totally mess-up Mach3's movement because CNC mill requires some acceleration and deceleration. The solution is remove all redundant feed rate commands and let Mach3 has enough time to accelerate/decelerate. For example:
Original skeinforge g-code:
==================================
G1 X-24.09 Y-12.52 Z0.52 F780.0
G1 X24.1 Y-12.52 Z0.52 F780.0
G1 X24.1 Y12.52 Z0.52 F780.0
G1 X-24.19 Y-5.27 Z1.16 F173.333
G1 X-17.28 Y-12.18 Z1.16 F173.333
G1 X-20.78 Y-10.37 Z2.02 F693.333
G1 X-20.78 Y-8.64 Z2.02 F693.333
G1 X10.41 Y-8.64 Z2.02 F693.333
==================================
After clean up
==================================
G1 X-24.09 Y-12.52 Z0.52 F780.0
G1 X24.1 Y-12.52 Z0.52
G1 X24.1 Y12.52 Z0.52
G1 X-24.19 Y-5.27 Z1.16 F173.333
G1 X-17.28 Y-12.18 Z1.16
G1 X-20.78 Y-10.37 Z2.02 F693.333
G1 X-20.78 Y-8.64 Z2.02
G1 X10.41 Y-8.64 Z2.02
==================================
Third, replace all M101/M103 motor start/stop commands to M8/M9 as we use coolant pump signal to control the feeder. Notice that before you turn on the motor, you must use "M108 Rxxx" to set motor speed. If you do not set speed first, M8/M9 will not work because motor speed still zero.
7. Now everything is ready to run , all you need to do is hit start button in Mach3 and watch your CNC transform itself to a 3D printer.

Nuri Erginer developed an addon for Mach3 CNC software that upgrades it to run modified Skeinforge   inside Mach3 program itself. You will then need to use only Mach3 software both for slicing the .STL file and 3d printing directly.
The CNC machine will, of course, need some hardware upgrades such as printhead as well to fully turn your CNC into 3d printer, but this software upgrade will make your CNC hacking much easier.

Here is another way to use Mach3 on CNC machine as 3d printer, and description of hardware needed. One could combine those two methods.

Digital manufacturing solutions are getting cheaper and more closer to DIYers. This sub 5000 USD waterjet cutter slices metal and this technology could be in your workshop soon.



From video description:

Hydro: The First Low Cost Waterjet
Senior Design Project -- University of Pennsylvania (2012)
Adam Libert - www.AdamLibert.com
Objective:
My team of five decided to create the first ever, small-scale, low-cost, and easy-to-use waterjet cutter, finally making this great technology available to hobbyists and small businesses on a budget.

Project Details:
I was the lead mechanical designer on this project and custom designed a fully waterproof and environmentally sealed XY gantry that would be able to withstand the water and abrasive from the waterjet. The waterjet has a cutting work space of 12"x14" and yet the machine is entirely self-contained to a footprint of only 2 feet by 2 feet, meaning that it can be easily rolled through a doorway and fit in the corner of any room. As well, it requires only a typical electrical outlet and shop air supply to run, making it a feasible option for universities, hobbyists, and small businesses with a budget of $5000 or less. The waterjet is low maintenance, requires only minimal training to run, and is able to cut through 1/4" aluminum and 1/8" steel to a tolerance of 0.005".

Results:
This project won the Mechanical Engineering Senior Design competition, and each of us on the team was presented with the Gemmill Award for Outstanding Creativity.
