Most of our projects start with a natural inspiration, but Kinematics emerged from a very different perspective. This project started with a technical problem: how can we create large objects quickly on a desktop 3D printer?
…From the beginning, this project was focused making the most of the limitations of low-cost 3D printers. Unlike most of our work, which occurs almost entirely digitally before we see a real object, this required extensive physical prototyping. We used our MakerBot Replicator (v1, dual extruder) throughout the prototyping period to develop and refine our concept.
Initially, we weren’t sure it was possible to design interlocking components that a desktop 3D printer could accurately reproduce while being small enough to comfortably wearable. But looking around the 3D printing community site Thingiverse, we found a diverse array of flexible structures all designed to be 3d-printed on low cost machines. Starting from there, we knew that it could be done.
We began by modeling a hinged joint mechanism based on a double-ended cone pin and socket. Cone-based geometry works well because, with the correct angle, it is self supporting, an essential quality for low-cost home printing. We spent a lot of time tweaking tolerances to get the hinge just right: tight enough to not fall apart but loose enough to not fuse together during printing. We kept refining the joint until it was as small as it could be and still print reliably.
With the joint designed, we started out printing simple chains of components. These basic configurations were already fun to play with, but we suspected they could be much more compelling. Taking origami tessellations as inspiration, we started making triangulated, foldable surfaces. Beginning with a regular tiling of equilateral triangles, we modeled the first assemblages entirely by hand. By using hinges to connect together small triangular panels, we were able to create a faceted, fabric-like material.
However, even modeling a simple, repetitive pattern is time consuming and difficult. Before we could continue, we needed to automate the generation of the hinge mechanisms on arbitrarily complex patterns. With that done, we could start to design tools that would let anyone morph and shape a pattern to create their own fabric-like creation. Early experiments also tried different ways we could style the modules or incorporate the multi-material extrusion available on newer desktop printers.
The results were compelling. Not only were were the pieces themselves addictive to play with, but it served as a case study in customization. Using the most inexpensive home printers, we could make complex, fully customized products in under an hour. However, as we worked on the project we realized the Kinematics system opened up a lot more possibilities….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
Hod Lipson, a Cornell engineering professor and one of the nation’s top 3-D printing experts helped A. J. Jacobs plan and execute a 3D printed-only dinner date, for a project for the NYTimes.com:
THE hype over 3-D printing intensifies by the day. Will it save the world? Will it bring on the apocalypse, with millions manufacturing their own AK-47s? Or is it all an absurd hubbub about a machine that spits out chintzy plastic trinkets? I decided to investigate.
…I settled on the idea of creating a 3-D-printed meal. I’d make 3-D-printed plates, forks, place mats, napkin rings, candlesticks — and, of course, 3-D-printed food. Yes, cuisine can be 3-D printed, too. And, in fact, Mr. Lipson thinks food might be this technology’s killer app. (More on that later.)
I wanted to serve the meal to my wife as the ultimate high-tech romantic dinner date. A friend suggested that, to finish the evening off, we hire a Manhattan-based company that scans and makes 3-D replicas of your private parts. That’s where I drew the line.
As it turned out, the dinner was perhaps the most labor-intensive meal in history. But it did give me a taste of the future, in both its utopian and dystopian aspects….
Introducing the Baricuda Extruder for 3D Printing Sugar and Chocolate
Derived from the venerable MakerBot MK2 Frostruder, this air-pressure driven extruder (“baric”) is a *U*niversal extruder because it adds a *D*egree *A*mplifier (yep… temperature) to let you extrude anything.
This time we’re going to be doing an autopsy on a Heathkit Grid Dip Meter. Lets begin!
The Heathkit Grid Dip Meter was initially released in 1953 for $20. The designed use of the grid dip meter is to measure high-frequency radio and television equipment. As you’ll see from the schematic on the last page, it is basically just a high-frequency oscillator. There were several listed uses for this device, including detecting resonant frequencies and acting as a tone generator.
Kinematics is a branch of mechanics that describes the motion of objects, often described as the “geometry of motion.” We use the term Kinematics to allude to the core of the project, the use of simulation to model the movement of complex assemblages of jointed parts.
Kinematics produces designs composed of 10’s to 1000’s of unique components that interlock to construct dynamic, mechanical structures. Each component is rigid, but in aggregate they behave as a continuous fabric. Though made of many distinct pieces, these designs require no assembly. Instead the hinge mechanisms are 3D printed in-place and work straight out of the machine.
Kinematics is a system for 4D printing that creates complex, foldable forms composed of articulated modules. The system provides a way to turn any three-dimensional shape into a flexible structure using 3D printing. Kinematics combines computational geometry techniques with rigid body physics and customization. Practically, Kinematics allows us to take large objects and compress them down for 3D printing through simulation. It also enables the production of intricately patterned wearables that conform flexibly to the body.
An application to extract a 5 second looping video from a non-looping input video. Also a viewer application to enable both interactive control over the level of dynamism of the output video, as well as manual editing of which regions animate or are static.
Although they were painted more than thirty years ago, years before the rise of the personal computer and the Internet, they look like they were done yesterday. They evoke the underside of carpets, circuit boards, intricate mazes with no possibility of escape, an alien language, a secret computer code or a highly evolved video game for math whizzes. They are hypnotic and subversive, enthralling and repellant. It is as if Young wanted to see how much visual information a painting could hold and yet still be porous, as if the wind could blow through it. Young’s paintings have always been about seeing rather than about being seen, not unlike their maker.
Russian photographer Alexey Kijatov‘s DIY camera may not appear to be very sophisticated, but it takes beautiful photographs of crystal clear snowflakes, capturing their icy and delicate uniqueness. To create this camera, Kljatov attached an old and inexpensive 44M-5 Helios lens to his Canon Powershot A650 using a board, tape, a screw, and a piece of glass. (You can read a more in-depth description of the process on this blog post.)
These featured photographs were all shot on dark woollen fabric in natural light (typically a grey cloudy sky), but Kljatov also shoots the flakes against a piece of glass. Whichever background he uses, Kljatov captures the elegant geometry of each flake without the use of fancy equipment.
Chris Labrooy is United Kingdom based artist and graphic designer who thrives in small projects which take a small idea and run with it. His most recent project, Auto Aerobics began as an exercise in place and context. Inspired by a winter trip to Brooklyn, La Brooy began to manipulate a Pontiac car which originally only served as a background object, but became the focus of the entire series.
By taking the familiar shapes and forms of the American Auto’s chassis, La Brooy digitally manipulates them by bending, stretching and combining, and seemlessly building them into the landscapes which they were inspired by. The bizarre, impossible, and totally impracticle images result in strikingly memorable floating sculptures that feel both alien and familiar.
Oracle is an amalgam of concepts tied together by the common thread of the user interface. To that end, it is a reflection of AI and UI as they exist in society’s consciousness: On first glance masculine, cold and austere; yet muted in its austerity and restrained by a warmth that is undeniably feminine.
Oracle was crafted by utilising a hacked Kinect depth sensor as a 3D scanner, modeled in 3D space and 3D laser printed using a durable Nylon Polymer.
This animation consists of 12,597 handmade aquarelle paintings, each painting is approximately 1,5*3cm in size. Together they form my 35 minute long paraphrase on the motion picture Blade Runner (1982) by Ridley Scott.
“Blade Runner – The Aquarelle Edition” follows the original movie´s storyline but I have taken the liberty to change a lot of things. It was never my intent to make an exact version of the movie, that would fill no purpose. Instead I wanted to create a something different and never before seen — “The Aquarelle Edition”.
…So this one is dedicated to everybody with any kind of heart. Enjoy!
From an interview with Silvia Scaravaggi for digicult.it:
There are 14 slide projectors that are standing next to each other. Each one has a slide with a piece of ordinary tin foil in it, in which I made holes with a small needle. The light goes through the holes and hits the wall. What appears is a kind of cityscape, like standing on a hill in Rome and looking over the city – or flying onto Los Angeles. Even though all the projectors use the same type of lamp – the light colour that hits the wall differs from machine to machine – from very white to quite yellow. Very similar to the different kind of lights in a city.
The ventilation of all the projectors together produce a permanent but somehow distanced sound. It is almost a romantic scenery – but there is the line of projectors between the image and the viewer. The ventilation sound that could be quite annoying turns into something soothing. The piece draws you in like a film – but unlike a film it always keeps you very aware of what it is, since the “making of” is always part of the piece. In an exhibition this sort of equilibrium between film and a sculpture is what I am looking for.
The Adjustable Clampersand is a rare and precious thing: a true Core77-born commodity. Its first inkling was an original Coretoon by Tony Ruth, showing the typographical tool in sketchy form. And now, with much hard work and horn-tooting, you can find the fully-fledged and functional Clampersand. The glittering conjunction is made from aluminum, cast at the Batavia Foundry outside of Chicago.
Writes the designer: “I always envisioned the Clampersand as an ideal bookend for an open ended shelf. I use them to clamp several books upright into a freestanding centerpiece. Or I simply stand it up by itself on a table. I’d recommend using it to clamp verbally associated objects together into some sort of visual pun: bacon and eggs, salt and pepper, turner and hooch. That sort of thing.”
The clamps receive a rough polish and a secondary base grinding, ensuring that they sit flat while clamped. While the Clampersand is fully functional, it is not recommended as an actual shop clamp, because the cast aluminum is a lower strength material than a traditional steel clamp.
You heard it (and saw it) here first: git your fresh Clampersands, clamp them around the house, shop and garden for all your bookending puns and visual run-on sentences. Punctuate your projects, support American
Puzzle Facade brings the experience of solving a Rubik’s cube to the urban space. It transforms the Ars Electronica’s media facade (Linz, Austria), into a giant Rubik’s cube.
In Puzzle Facade the player interacts with the specially designed interface-cube. The interface-cube doesn’t have color stickers and it holds several electronic components (an Arduino Pro Mini, an IMU, a LIPO battery, rotary encoders..) on its inside that allow to keep track of its orientation and rotations. This data is sent over Bluetooth to a computer that runs the Puzzle Facade designed software. This software visualizes the cube on the large-scale Ars Electronica’s media facade according with the interaction of the player with the interface-cube.
