2. Once you have this controller, you can basically use it for any kinds of stepper motors based 3D printers that you can find in the reprap.org. Which also includes the most popular models like Prusa and Original Mendel.

3. It's an easy to use and easy to install Electronic kit that never before, Everything is pre-labelled, properly set up and well organized. All you need to do is finding the right pins and make simple connections.

Features:

Atmel ATmega 2560 with ATmega16U2

Flash Memory: 248KB
SRAM: 8KB
EEPROM: 4KB
Input Voltage: 12V
clockSpeed: 16MHz
MircoSD slot: Yes
LCD pins: Yes
Joystick: Yes
Motor Driver: 4 x Integrated Allegro A4982
PWN Fan: Yes
Heatbed: Yes
Endstops: 4
External Serial ports: Yes
External I2C ports: Yes
External Reset Pins: Yes

Four integrated Allegro A4982 Stepper Driver

Buildin Push-Push microSD card socket

2 N-MOSFETs for Extruder and Heatbed control
1 N-MOSFET for low power PWM Mosfet driven outputs

External Reset button for emergency stop
External 5V supply and GND for any other modules
External Joystick connection pins for manual control
External LCD connection pins for standard 20x4 LCD

Extra pins available for Raspberry Pi expansion and development;
RX,Tx and GND
SDA, SCL and GND

Physical Characteristics
4-Layer PCB with proper ground plane and power distribution networks
The maximum length and width of the Baboi are 115 and 60 mm respectively, with the USB connector and power
terminals extendng beyond the former dimension. Three screw holes allow the board to be attacted to a surface or case. Baboi is deigned to be compatible with most of 3D printers in the current market.
Further from that, UART(serial port) is also connected as external pins for Raspberry Pi for further development uses.

USB overcurrent Protection
Babo has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed.

3 Modes for Baboi Box:

1. SD Card Printing mode

You can store all your gcode into MicroSD card and inserted into Baboi box, It would automatic read your gcode and start printing after it reach its printing temperature.

2. Manual Control Mode

This mode is perfect for open source 3D printers, as we all known open hardware 3D printer is not as stable as other finished products. So that you will find this mode very useful when you first time set up your printers or when you fix hardware problems. It's an easy-to-use hardware testing function.

3. PC Mode

For people who still like to connect your 3D printer to Computer, here's the mode that you probably would use.

Mendel90 with lasercut MDF frame and acrylic enclosure

This looks cool. Maybe I'll find a laser cutter (which is not the easiest task in rural Croatia) in the future and try to build it. I wonder what are the heat retention impacts on print quality ...











From project description:
A modified version of the Mendel90 which uses a lasercut melamine coated MDF frame (same fixing idea as the graber i3 frame). It allows an acrylic enclosure to be fitted. 
Main changes:
Frame re-designed, Z axis changed to laser cut parts.
Some plastic parts modified (not many)
Acrylic enclosure added
Wiring simplified - all motors have detachable plugs, endstops are push fit. this allows for a wiring loom to be used.
RAMPS electronics as standard with the Panelolu2 controller.
All the detail is available on our blog:
http://blog.think3dprint3d.com/2013/09/mendel90-laser-cut-ready-to-print.html
The assembly process in more detail in in this post:http://blog.think3dprint3d.com/2013/10/mendel90-lasercut-overview.html
The commissioning and calibration in outline is here:
http://blog.think3dprint3d.com/2013/10/mendel90-lasercut-calibration.html
The printer is designed from the start to take multiple bowden extruders as an alternative to a single direct drive extruder. Updates will follow!

3D printed titanium horseshoes


































From the source:

Scientists have channeled their inner shoe designer for this latest project – and just in time for Spring Racing Carnival.
In a horse-ome titanium 3D printing first, our scientists have scanned a race horse’s hooves using a handheld scanner and then, with sophisticated modelling software they designed the perfect fitting, lightweight racing shoe.
Four of the customized kicks were printed within only a few hours!
“3D printing a race horse shoe from titanium is a first for scientists and demonstrates the range of applications the technology can be used for, although it’s certainly very different from our everyday work,” said our titanium expert, John Barnes.

Break the Mould documentary from 3dify on Vimeo.

Documentary following the project Break the Mould - an interactive 3D scanning and printing art installation that took place during the Brighton Digital Festival 2013. The scanner was housed inside a giant willow sculpture to give participants the experience of stepping inside a giant womb where they were 3D scanned and then printed out as 8cm high figures on Ultimaker 3D printers.

3Dify built the 3D scanner using a rig of their own design, an Xbox360 and Skanect. The rig rotated around the person at various heights and was controlled using an arduino and piloted using a retro 80's joystick.

3Dsimo - multimaterial 3d drawing pen
































From the 3Dsimo project Indiegogo page:

3Dsimo as a first on the world provides to user the possibility to choose print options on a digital display. The adjustability of temperature and speed of materials throughput now offer amazing opportunities for your creativity. We can handle various materials as ABS, PLA, PVA (water-soluble material), nylon at different temperatures in order to achieve fast filling or even print in the air.
Other options include backlight, turn on preheating or memory for storing settings. These parameters are used to determine the appropriate method of drawing.
Do not be limited by the choice of materials, for example choose between golden, silver, wooden or flexible PLA. Over time, new materials will be increasing due to the growing trend of 3D printing. Our 3Dsimo is fully prepared for this due to configurability of all parameters and thermal feedback for determining the exact temperature.
How it works?
3Dsimo is so simple to use as a pencil. Everyone who have ever draw with pencil will not have a problem to use 3Dsimo. After plugging it in you set the desired speed and temperature according to the material (these data will be appended together with 3Dsimo and new materials will be updated). 3Dsimo is based on the principle of FDM technology thus extruding plastic material through the hot end. If you want to print into the air or create infill of any object you can do it easily and quickly. There is no problem just make your choice. After a while of use you will find that with 3Dsimo you can create fantastic objects.
3Dsimo has many utilization:
Repairing of plastic devices
Bonding and assembling models of 3D printers
Repair abortive print (due to repair you don’t need to enter new several hours lasting print)
Creating jewelry
To implement your ideas
Simply for the joy of modeling

Skull shaped microscopic 3d printed bacterial cages

From the source:
By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections.
In a recent experiment they demonstrated that a community of Staphylococcus aureus, which can cause some skin infections, became more resistant to antibiotics when it was contained within a larger community of Pseudomonas aeruginosa, a bacteria involved in various diseases, including cystic fibrosis.
The work was published this week in the Proceedings of the National Academy of Sciences.
The researchers use a novel 3-D printing technology to build homes for bacteria at a microscopic level. Their method uses a laser to construct protein "cages" around bacteria in gelatin. The resulting structures can be of almost any shape or size, and can be moved around in relationship to other structures containing bacterial microcommunities.
The method should enable an entirely new class of experiments that better approximate the conditions that bacteria encounter in actual biological environments, such as those in the human body.
