This week we are presenting you a new tutorial on 3d printing of Lego-compatible pieces with Materia 101. Kristoffer designed a brick with the parametric 3d modeler FreeCAD that can hold a small servo. Following the 10-step instructions you can easily add wheels to robots built in LEGO and use specific servos with different sizes.
Using a 3d printer means playing with some hardware but especially some softwares. In the tutorial of this week, the fourth tutorial of our series , Kris is going to introduce you how to work with Slic3r, a G-Code generator for 3d printers and basically a tool you need to convert a digital 3D model into printing instructions for your 3D printer. Slic3r is an open source software able to cut the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded so that you can reach good results.
The object you’ll be able to print with your Materia 101 is a pirate hook !
When you become a happy owner of a Materia 101 3d printer, the first days are really important to start experimenting with the right attitude. Understanding quickly how to get what you want from it means becoming aware of the potential applications of the 3d printing technology in your environment.
Take a look at the second tutorial focused on fixing things at home: “Making something useful” tutorial shows you how to start from a need, to design and print a solution. It feels great to be able to fix what’s broken!
Interested in getting in touch and showing your experiments? Join Kristoffer on the Arduino forum and give us your feedback.
Next week we are going to post a tutorial on how to create 3d-printed cases for Arduino boards. Stay tuned.
I’ve always fantasised about having a kiln in the garage (Eben wants a pick and place machine; we need another garage). Kilns, though, are expensive. And where do you start if you want to refurbish a broken or old one safely?
James Gao has an answer, and it’s got a Raspberry Pi in it. (Well, not in it, but attached very firmly to it.
James’s girlfriend is an enthusiastic potter, and James is an equally enthusiastic hacker. They came together and made beautiful music a kiln. The project is based around an old electric kiln, which James built holes into to convert it into a propane-fired updraft kiln. A Raspberry Pi is hooked up to a thermocouple and a stepper motor that controls the propane regulator. James 3d-printed gears and a clamp to operate the regulator/motor setup.
Stepper motor and propane regulator
The kiln operates via a PID, which controls the temperature taking closed-loop feedback from the thermocouple to the regulator. Adjustments can be made remotely; the kiln controller system has WiFi. James has a really interesting series of photographs, with explanatory text and some examples of test firings, over at imgur; he also answers questions about the project at Reddit.
Results of two test firings – the variously floppy things are pyrometric cones, used to measure temperature in different parts of the kiln.
There are so many reasons I love this project. It’s a wonderful demonstration of what can be done with no specialised experience (James had never worked with kilns before starting this project, and neither he nor his girlfriend had any knowledge about firing pottery). The ingenuity on show is just brilliant (3d-printed gears!), the pottery that comes out of the end is immensely satisfying – and face it; there’s something very thrilling about flames. On top of all this, the whole project came in at less than $200.
If you’re unlucky enough to have required precise, timed doses of drugs through an IV in hospital; or if you’ve worked in a lab where controlled amounts of chemicals have needed to be added to an experiment on schedule, you’ll be intimately familiar with syringe pumps. They look like this.
And they’re expensive. The one in the picture above, which was the cheapest I could find (in an admittedly very quick and dirty Googling session) costs $750. As with a lot of specialised scientific equipment, that means that it’s difficult for hospitals with restricted incomes, or for labs with a lot of overheads, to get their hands on as many as they need for their work. This applies to cash-strapped university departments and hospitals in your town every bit as much as it applies to organisations in the developing world: equipment like this can be prohibitively costly wherever you are.
Joshua Pearce led a team of graduates and undergraduates from Michigan Tech‘s Open Sustainability Technology Lab in a project that intended to do something about that. They have created an open-source, 3D-printed syringe pump that can be made for a fraction of the cost of existing pumps, using an off-the-shelf motor and bearings, which is driven by a Raspberry Pi. The whole system comes in at about $50: that’s a fifteenth the price of the pump in the picture above, and it performs exactly the same task, in exactly the same way.
The plastic parts are made with a 3D printer; a Raspberry Pi acts as a control and calibration unit.
Megan Frost is a biological researcher at Michigan Tech, who has been using the open-source syringe pump in her work with cell cultures. She says:
“What’s beautiful about what Joshua is doing is that it lets us run three or four experiments in parallel, because we can get the equipment for so much less,” she said. “We’d always wanted to run experiments concurrently, but we couldn’t because the syringe pumps cost so much. This has really opened doors for us.”
Cost can be a devastating barrier to entry to the sciences, and for basic health needs like pharmaceuticals delivery. One of the things we were trying to address when we created the Pi was the high cost of computing. We’re strong believers in democratising access to technology, and this project’s a perfect example of how to do that.
After the sneak peak of some days ago, we are happy to officially announce the Arduino 3d printer . Completely open source and affordable, Arduino Materia 101 is a device aiming at simplifying access to the world of 3D printing and rapid prototyping.
Materia 101 is a precision 3D printer running on Arduino Mega, designed and developed in Italy, thanks to the collaboration of Arduino and Sharebot, two companies working with a similar approach to technology. It is ideal for beginners, makers and education.
Materia 101’s visual identity is curated by studio ToDo: the choice of essentiality of design and the white color of the machine suggests its ease of use.
The printer will be available only on the Arduino Store both as a kit and pre-assembled. Official pricing of the device will be disclosed at a later date but the kit will sell for less than 600 EUR/800 USD, while the pre-assembled version will be available for less than 700 EUR/1000 USD. The official presentation will be held during Maker Faire Rome, 3-5 October 2014.

‘Draw It Yourself’ is a MIDI controller created by Dani Sanz which uses conductive ink as push-buttons. It is based on Arduino Uno and uses a capacitive sensor to determine whether the drawn buttons are being touched or not:
This was my second semester project for the Interactive Music Systems Design Course (CDSIM) at the Music Technology Group (MTG) at University Pompeu Fabra of Barcelona. I presented this project at Sonar+D, part of the Sonar festival of Barcelona, held between June 12th and 14th 2014.
It can be used for multiple applications, not only for music! You can download the Fritzing and make it yourself on the Instructable and see it in action with this video:
Adafruit’s 3D Thursday series is getting us terribly excited every time they roll out a new project with a Pi in it. Yesterday’s was a doozy: so much so that the engineering team stood around my desk and made puppy-dog eyes and sighing sounds at me until I agreed to email LadyAda and beg a demo sample of the project from them. (She says she’s sending the pink one, Gordon, just to punish you for being so demanding.)
Meet the extraordinary PiGrrl, a home-baked Raspberry Pi clone of the Game Boy.
If you don’t think that’s the best thing ever, you’re dead inside.
As always with Adafruit projects, the PiGrrl is documented minutely; you can find a complete tutorial on their website, along with files for the 3d printer at Thingiverse. This is one of the more complicated builds we’ve featured, but we think the results speak for themselves
LadyAda says: “Woohoo!” After careful consideration, so do we.
The State University of New York at New Paltz is home to the world’s first MakerBot Innovation Center: a ground-floor room with 30 MakerBot Replicator 3D Printers. “3D printing is training students to think in a different way,” says Dan Freedman, dean of science and engineering at New Paltz. “If students come out of here knowing about 3D printing and different applications of it, it will give them a better chance of starting a career.”
It’s not only college students at the center. Faculty from many disciplines and other New Paltz staff have attended sessions with MakerBot trainers. Local artists and manufacturers, as well as others who want to learn about 3D printing without pursuing a degree, can enroll in a two-semester program in digital design and fabrication. And New Paltz has plans to bring in students from local public schools. For bringing the community together, says Freedman, “the only thing similar is the gym.”
Interested in a MakerBot Innovation Center? Let us know.
The MakerBot Innovation Center at New Paltz is part of The Hudson Valley Advanced Manufacturing Center, a $1.5 million initiative to spur regional economic development. The advanced manufacturing center received $250,000 donations from a local venture-capital fund and a matching grant from the regional utility company. “It was the easiest donation this college has ever gotten,” says Freedman, “We were in the right place at the right time.”
“This is a technology that is just starting, and it’s going to become increasingly important,” says Freedman, who thinks that the university’s investment in 3D printing will make New Paltz the right place for budding artists and the engineers of tomorrow.
Katherine Wilson, a student in New Paltz’s renowned Metal program, says, “When I was looking for graduate schools, I was interested in what kind of technology was available.” Before opening the Innovation Center, New Paltz had a few MakerBot Replicator 3D Printers, and she was careful not to monopolize them. Access to an array of 30 3D printers has freed up Wilson to follow her imagination wherever it takes her.
Freedman adds, “I think we can attract some really outstanding students who are undecided between science-engineering and art and say to them, ‘You can pursue your interests in both areas, and we’re going to make it easier for you to do that.’”
