These 3D printed mobiles are the result of a collaboration between Marco Mahler, a kinetic sculptor specializing in mobiles, and Henry Segerman, a research fellow in the Department of Mathematics and Statistics at the University of Melbourne.
These mobiles come out of the 3D-printer completely assembled as shown in the photos and video. They are made of separate loose pieces connected to each other. The balance points for these mobiles were calculated to 1/1000th of a millimeter (1/25360th of an inch). The models for some of these mobiles were drawn up “by hand”, others were created utilizing scripts that we wrote. Some of the mobiles, like Mobile 4.2, are designed with a very small increase or decrease in thickness from one part to the next, something that is not possible to do with conventional handmade mobiles. Utilizing scripts also allows for designs that would be very time consuming to make by hand, such as the Quaternary Tree (Level 6), which has 1365 pieces.
We met via Twitter (Marco lives in Portland, Oregon, Henry in Melbourne, Australia) in early February 2013 when Henry was looking for suggestions for a motor for one of his 3D printed kinetic sculptures. A conversation ensued about the possibilities for making 3D printed mobiles. After about 300 emails, several conversations over Skype, hundreds of lines of code, and a number of test prints and trial-and-error experiments, the result is the collection of mobiles that is now available through our shop at Shapeways (a 3D printing service company). After an extensive Google search, it appears that these are the first fully 3D printed mobiles in the world.
All models are available in “White Strong & Flexible”, a laser sintered nylon plastic, one of the most popular materials for 3D-printing. Some of the smaller models are also available in “Black Strong & Flexible” and a variety of polished colors. This material is heatproof to 80C/176F degrees. Higher temperatures may significantly change material properties. It is also dishwasher safe (“Yay, finally a mobile we can put in the dishwasher!”).

Reprap Morgan is a concentric dual arm SCARA FDM 3D printer, designed and built by Quentin Harley. The SCARA stands for Selective Compliant Assembly Robot Arm or Selective Compliant Articulated Robot Arm. Harley has been working on this project for a couple of years, and in February Harley released pictures showing off the build. The extruder of this Reprap Morgan 3D printer moves along the x and y axes and the bed itself moves along the Z axis. Its major parts, such as the arms, driving gears, pipe adapters are printed on a 3D printer.
Yesterday Harley has officially released the Morgan plans, this is a big step for the development of entry-level 3D printers. This printer is very simple and easy to assemble, and built with only affordable consumables.
“RepRAP Morgan is all about a dream. A dream to make it easy for anyone in South Africa, or anywhere else in the world to build a 3D printer without needing exceedingly expensive materials, hard to find components, stuff that has to be shipped at sometimes more than the cost of the components, requiring advanced tools.” Notes Harley. “Morgan is to be a tool for creation, not a toy or end product. It should be used in education, and must be affordable and safe enough for school kids to use.” adds Harley.
Terry Wohlers, an industry consultant, analyst, and speaker, president of independent consulting firm Wohlers Associates, provided some impressive insights into the market of Additive Manufacturing during their preparation for the publication of Wohlers Report 2013.
He revealed some interesting data: “16 companies in Europe, 7 in China, 5 in the U.S., and 2 in Japan now manufacture and sell professional-grade, industrial additive manufacturing (AM) and 3D printing systems. This is a dramatic change from a decade ago when the mix was 10 in the U.S., 7 in Europe, 7 in Japan, and 3 in China.”
Last year, the Obama Administration announced the launch of the new National Additive Manufacturing Innovation Institute (NAMII) to be housed in renovated industrial space in Youngstown, aiming to help lead a renaissance in U.S. manufacturing. “This institute will help make sure that the manufacturing jobs of tomorrow take root not in places like China or India, but right here in the United States,” Obama said.
Is the U.S. losing its edge in AM? This data on AM systems manufacturing and sales suggests that it is. Notes Wohlers:
What’s more, all of the metal powder bed fusion systems are manufactured outside the U.S. Seven manufacturers of these systems are in Europe and two are in China. Together, China, Singapore, many countries in Europe, and even South Africa, have committed hundreds of millions of dollars in AM development and commercialization over the next few years.
The U.S. continues to lead the world with the largest installed base of AM users. When Wohlers Report 2013 becomes available soon, it will report that 38% of all industrial AM installations are in the U.S. Japan is second with 9.7%, followed by Germany with 9.4% and China with 8.7%. With such a large number of systems, one could argue that the U.S. has the most experience, expertise, and know-how in AM.
The NAMII was launched by the White House with the support of several agencies, including the Department of Defense. This initiative seeks to accelerate the position of the U.S. in the development and use of AM technology. It will not be easy, given what organizations in China and other regions of the world have planned.
My recommendation to key leaders in the U.S. is to focus on the big picture with big goals, such as the development of metal-based powder bed fusion systems and other advanced AM system technology. Market forces and competitive pressures will take care of the smaller challenges and incremental technology improvements.

I ordered the Experimentation Kit for Arduino and I am addicted! Thank you! I have heard a lot of people talking about Arduino, but I think most people are still intimidated because they don’t know electronics or they are afraid of programming. I have been a systems engineer since 1992 and have written several web apps and iPhone apps.
In late April, the 16-year-old central Florida honor student was accused of igniting a chemical explosion on school grounds, leading to her arrest and suspension from school, but authorities dropped criminal chargeslast week.
The nightmarish ordeal was shocking for her single mother, Marie Wilmot, who always encouraged Kiera and her twin sister, Kayla, to follow their passions.
“The initial phone call was terrifying,” Marie told ABC News. “Time will help I hope, it was devastating for me as a mother.”
While school officials debate whether Kiera will return to Bartow High School, the Wilmot family received an unexpected surprise.
The explosion struck a chord with 18-year NASA veteran Homer Hickam, a former lead astronaut training manager for Spacelab, and later for the International Space Station.
Writing a basic I2C or SPI driver for your sensor is only 1/2 the work (often less!). All of the real magic is doing something with that sensor data, and that often means getting your hands dirty with some basic DSP (digital signal processing). I stumbled across this paper on filtering sensor data to balance a device, but it shows a lot of the tradeoffs and decisions that go into making real-world use of raw sensor data. (See The Balance Filter: A Simple Solution for Integrating Accelerometer and Gyroscope Measurements for a Balancing Platform by Scott Colton.) DSP is an extremely interesting field, and there a lot of fun challenges to be had, but picking the right filters (with the right performance characteristics) can take some thought. Have any fun stories yourself where a favorite filter saved the day? Post the up in the comments below!
Will blinking blue lights of servers soon fill the aisles that previously offered the Blue Light Special? Sears Holdings has formed a new unit to market space from former Sears and Kmart retail stores as a home for data centers, disaster recovery space and wireless towers.
With the creation of Ubiquity Critical Environments, Sears hopes to convert the retail icons of the 20th century into the Internet infrastructure to power the 21st century digital economy. Sears Holdings has one of the largest real estate portfolios in the country, with 3,200 properties spanning 25 million square feet of space. That includes dozens of Sears and Kmart stores that have been closed over the years.
Don’t get us wrong, Fabrican is amazing. But it is not new, and serves as a reminder of just how long it can take to bring a good idea to market, and how dogged inventors need to be. Manel Torres first conceived of Fabrican way back in 1995, when he was an RCA student studying fashion design, after watching a friend get sprayed with Silly String. Torres began to collaborate with chemical engineers, and by 2000 he’d filed a patent and set up R&D facilities at Imperial College London.
Three years later Torres formed Fabrican Ltd., and another three years went by before the blogosphere picked up on the stuff. Here in 2013, seven years later, there are still no announcements for commercialization; the “News” section of Fabrican’s website saw its last update in 2010.
Has Torres given up? Doesn’t look like it, as he’s delivered several Fabrican-based TED Talks as recently as last year. We can only speculate as to what’s preventing the appearance of Fabrican on store shelves, which is what we’d really like to see; while Torres is proposing industrial solutions targeted at the medical, automotive and fashion design industries, we think selling the stuff in cans and letting you guys figure out what to do with it would be a good way to go.
You can design, print and etch your own PCBs from a flexible sheet of Kapton coated with a thin layer of copper. To do this yourself you need some special materials and equipment, and if you are not planning on etching circuits more regularly then it can be nice to start by looking for a local space that has an etching setup you can use.

NEW PRODUCT – Right Angle USB cable – A/MicroB – This here is your standard A to micro-B USB cable, for USB 1.1 or 2.0, but with a twist! Literally! Instead of the cable coming straight out from the connector, there’s a right angle bend. We thought this might make a good pair for a Raspberry Pi as the cable doesn’t stick out as far. We got cables with extra-beefy 24 AWG power wires, and 28 AWG data lines, so it’s particularly good for power-hungry devices like micro-computers and phones.
Next we cut out a little circle of conductive fabric and split it in two and sewed them onto the left shoulder blade. We took conductive thread, sewed it into the VBATT hole, and connected it to one of the conductive fabric circle halves. We then sewed a new piece of conductive thread from the unused half circle, and connected it through all of the positive ends of the LED lights.
By interrupting the circuit using the conductive fabric half circles, when someone wearing conductive thread on their right wrist, the circuit will complete when they put their arm around the person wearing the sweater.

Ever wish your clothes could change color to match each other? Make a chameleon scarf to match every outfit using the Flora color sensor and 12 color-changing LED pixels diffused by a ruffly knit scarf. Check out the video on YouTube (please subscribe!) and Vimeo, and make your own with the full tutorial on the Adafruit Learning System.
Flora Color Sensor – TCS34725 – Your electronics can now see in dazzling color with this lovely color light sensor. We found the best color sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The filter means you’ll get much truer color than most sensors, since humans don’t see IR. The sensor also has an incredible 3,800,000:1 dynamic range with adjustable integration time and gain so it is suited for use behind darkened glass or fabric.
