7-year-old amputee gets a 3D-printed prosthetic hand


California girl receives a high-tech, 3D-printed prosthetic hand — for $50.


When Faith Lennox was nine months old, she lost her left forearm. Now at age seven, she has received a custom ‘robohand’ through the powers of 3D printing.

The easy-to-use prosthetic weighs only one-pound and cost the Lennox family $50 — merely a fraction of the price of traditional, sensor-laden pieces. What’s more, when Faith outgrows the prosthetic, whether it’s six months or two years from now, a replacement can be made just as inexpensively and easily as the first.

After trying numerous prosthetics throughout the years, Faith found them to be too bulky, heavy, and worst of all, difficult to use. And while on the search for a better alternative, her parents came across volunteer group e-NABLE, who has helped kids and adults seeking artificial limbs to build them through 3D printing. Currently, the non-profit organizations says that they’ve assisted nearly 1,000 hands for 700 families so far using their free, open-source design files. From there, the combination of experts from Cal State-Dominguez Hills, design studio Build It Workspace, and an Airwolf 3D printer brought the project to life.

The seven-year-old even had the opportunity to choose the colors and watch the printing process firsthand inside the Makerspace. Naturally, she would go on to pick a scheme of pink, blue and purple. What’s even more impressive is that the entire process took just about 24 hours. After slipping on the end product — comprised of 20 individually printed plastic pieces along with some metal screws and nuts — she was able to control it by simply moving her upper arm up and down.

And just like any kid her age would do, Faith took to her bike to test out her newly-crafted arm. It was a success! This example, among many others we’ve seen in recent weeks, demonstrates the limitless potential of 3D printers.

3DFormer is a 3D printing pen for Makers


This easy-to-use, even easier-to-hold pen draws 3D models right in thin air.


While 3D printers may have stolen the buzz as of late, 3D pen makers aren’t too far behind in meeting the successes and mainstream appeal of their much larger siblings. In fact, handheld gadgets like the 3Doodler and Lix have already experienced multi-million dollar backings on Kickstarter over the last couple of years.

Hoping to be added to the list is new 3D printing pen 3DFormer, the brainchild of Austin-based Dim3printing LLC. Designed with students in mind, the device allows users to trace and draw 3D models right in thin air using FDM printing technology.

“3DFormer was developed for arts and STEM education projects. Kids may design and build artworks, and develop geometrical, engineering, and astronomical models for learning. 3DFormer may help kids to be more creative than ever,” the team writes. “Using 3DFormer together with other electronic or mechanical components, the inventions are instantly happening out of your imagination with a new look!”

Based on an ATmega8A, 3DFormer features a hexagon cylindrical shape with a 27mm grip width, and impressively, nonstop use of over two hours. Compatible with 1.75mm ABS and PLA 3D printers, users may feed the filament from either a standard 2.2lb spool or a stick. 3DFormer is looking to set itself apart from others on the market today through three key differentiators. These include continuous variable speed control, an ergonomic design for easy holding and precision in movement, and advanced cooling mechanisms to prevent clogging and ensure quick heat dissipation.

“The challenge in the 3D printing nozzle design is to maintain a high temperature to melt the ABS/PLA filament for extrusion while keeping temperature in filament feeding chamber low enough to avoid swelling in filaments. For a hand-operated 3D printing device, the form factor of the nozzle makes the challenge even bigger than that for the desktop 3D printers. On the other hand, to prevent injury from overheated nozzle we must keep outer shell temperature at 50 degree Celsius or lower.”

Beyond that, the pen is equipped with separate buttons to control the speed of the filament output and a minimum flow rate of 0.5mm per second, while a maximum filament flow rate is said to be upwards of 20mm per second. At this rate, its creators note that the extruded filament volume lets users deposit multi-layer plastics on a two-dimensional surface for layered structures and enhanced strength. What’s also nice is that the fan-free 3DFormer is super quiet, making it a welcomed addition in any classroom.

“We believe this is the right product for both 3D drawing fun and classroom practice,” explains Mr. Bin Hu, Dim3printing CEO. “Launching the 3DFormer on Kickstarter will help us to smooth mass production and get the product to our long waiting customers sooner.”

Those interested in a 3D pen can head over to its official Kickstarter page, where the team is currently seeking $20,000. Shipment to early bird backers is expected to begin in May 2015, with full-out delivery slated for June 2015. In the meantime, you can see it in action below.

Maker 3D prints a fully-functioning, Planck-inspired mechanical keyboard


Why go to Staples for a keyboard when you can print your own?


The Planck is a compact (40%) Ortholinear keyboard designed with ergomnomic thumb placement. For those unfamiliar the kits, the plate layouts are relatively the same as a traditional keyboard with the exception that the keys are all the same size. Recently, Maker Adam Forland 3D-printed and assembled a fully-functioning Planck-inspired mechanical keyboard.

“I just got into mechanical KBs a month ago but I was immediately drawn to the idea of a [DIY] keyboard. The plate, feet and key caps are all 3D-printed on my desktop printer,” Forland writes.

key

As you will notice, upon first glance, the keyboard may appear to be just like the ones you use regularly. However, this gadget omits an elongated space bar, and instead, uses a series of five yellow keys along the bottom to serve as navigation arrows and a function button.

To bring this idea to life, Forland employed his Lulzbot Mini 3D printer. The Maker notes that he needed to divide the main case of the device into two sections in order to accommodate its size, which measures approximately 9cm x 25cm x 3cm. Using a 0.5mm nozzle, he printed the board at a 0.3mm layer height and the actual keys at a 0.18mm layer height using ABS thermoplastic.

key6

The keyboard itself is powered by a Teensy 2.0 USB dev board (ATmega32U4) and programmed with a few different custom layouts. Beyond that, the project is equipped with some 20-gauge copper wire, 1N4148 doides and 48 Cherry MX green switches.

Maker builds a DIY SLA 3D printer for less than $30


This SLA 3D printer can be created using materials found throughout your home — and an Arduino.


Although many 3D printers strive for simplicity and affordability, this one surely takes the cake. Whereas a device under $500 may catch your attention, one that costs less than a Saturday night dinner surely will hold it. Buildyourownsla.com user “Mystamo” recently created a DIY SLA 3D printer for less than $30 that prints from the top-down or bottom-up, all powered through an Arduino Uno (ATmega328).

Laser

SLA typically features a bottom-up style due to issues like the need for more resin and layer height control. A projector or laser diode sits underneath the resin tank with transparent bottom and a non-stick surface, pointing upwards to cure the resin.

For his build, Mystamo had taken his top-down device and wanted to test as to whether it would work with his ACER 5360 720P projector for a bottom-up design as well. After some investigation, the projector was indeed suitable for the job without requiring much further customization other than removing its focus screw for manipulating the focus wheel and a little fine-tuning of the focus.

Printer

The Maker reveals that since he didn’t have Z-axis limits, he set the build plate just slightly above the resin surface with some resin pointing out of the his perf board holes. Mystamo acquired an inexpensive stepper drive that was soldered directly to the pin, and added a few connectors for easy removal. It also runs at 1/16 micro stepping. Beyond that, he refined his 3D printer by employing the Arduino to run a very simple HTL code with only minor modifications.

From there, the 3D printing process was ready to begin with 8-second exposures on the first three layers, and 2.5 second exposures on all other layers, all at 0.05mm per layer. While this particular design doesn’t use any 3D-printed parts itself, it still embodies true DIY spirit as the entire thing was devised using items found around the house. And in case you’re wondering, yes it works, as seen with his latest print: a Terminator skull.

China’s first 3D-printed car hits the road


A Chinese company has just completed a 3D-printed car for $1,770.


Hot off the heels of Local Motors, Sanya Sihai has created China’s first 3D-printed car: a bright orange electric-powered sedan. If you recall, the Chinese company previously developed the world’s first fully-functional boat last August, a two-meter long vessel capable of accommodating two passengers.

car4

The road-ready vehicle took a month and a half to complete, with the printing portion of the process requiring just five days — which is more than twice as long as the Strati’s 44-hour fabrication time. In total, the team says it only cost $1,770 to manufacture.

car7

The frame of the rechargeable battery-powered two-seater was printed using a composite material, then combined with traditionally manufactured components. Its distinctive color is the result of the Tyrant Gold filament used to construct the car’s body. Weighing approximately 500kg when all was said and done, the electric Shuya is capable of reaching speeds up to 24mph.

Intrigued? Watch the car as it hits the streets of the Hainan province in southern China.

Nellie is a 3D-printed weed-picking robot


This Arduino-powered bot may one day help farmers stay weed-free. 


Other than shoveling several inches of snow, there’s one outdoor chore that anyone would surely welcome robotic assistance: weeding. While there are already a number of plowing bots out in existence today, thanks to one Maker, the daunting lawn care task may soon be taken care of as well.

nellie4

A recent entry in MAKE: Magazine and Cornell University’s Pitch Your Prototype competition, Maker Mike Rigsby has developed a 3D-printed robot capable of, you guessed it, pulling out weeds! While at first this may sound like yet another mechanism to increase laziness, weeds are actually a serious problem for farmers all around the world — and it’s only getting worse. Take for instance Pigweed, which grows up to three inches per day and has become resistant to the dominant weed killers, threatening the nation’s soybean and corn crops.

“This is a serious attempt to address an agricultural problem,” Rigsby told the magazine. “I suspected that robots could handle the weeds and that the time to start working on such a solution is now, before the weeds develop further resistance to chemicals.”

And so Nellie was born. The robot spots and plucks them the old-fashioned way, one at a time. The current proof-of-concept is powered by a trio of Arduino Unos (ATmega328), a pair of Arduino motor shields, a Pixy camera, a Ping ultrasonic sensor, eleven AA NiMh batteries, a servo motor, a four-wheel drive base, along with some custom 3D-printed parts that were constructed using two AVR powered MakerBot Replicator 2.

nellie1

How it works is relatively simple. The Pixy camera spots a weed, then feeds the data over to the Arduino processors which relay the commands to the motor controller module to activate the grabber and close the pincer. Meanwhile, the Arduino-controlled motor shield enables the robot to move about the land in the right direction. At the moment, the device is only designed to roll over carpet.

Should the Maker win the contest’s grand prize, however, Rigsby hopes to use the winnings to devise another working prototype with a little more oomph, which can navigate a farm’s terrain. And who knows, perhaps in the coming months, everyday gardeners will be able to take advantage of Nellie, too.

“To advance the project requires money for parts. Nellie’s daughters and sons will need a heavy duty chassis that will run between rows of plants, reaching to the side to eliminate offensive weeds. They need multiple cameras and better vision to pinpoint the target. Weeds will be eliminated by pulling, burning, cutting, digging, electrocuting or some combination of methods,” Rigsby adds.

Until then, you can watch it in action below. Now this would make for a great Hackay Prize entry as well. Just sayin’.

BoXZY is a triple-threat tool that brings an entire Makerspace to your desk


BoXZY is an all-in-one CNC mill, laser engraver and 3D printer. 


We’ve seen plenty of 3D printers. We’ve seen a number of CNC mills. We’ve seen countless laser engravers. Yet, a combination of all three is a much rarer sight. Developed by two brothers from Pittsburgh, Joel and Justin Johnson, their recently-revealed machine is shaping up to be a multi-purpose masterpiece that will appeal to both beginners and experienced Makers alike. The BoXZY has been developed to serve as a complete desktop manufacturing space, rather than just a 3D printer with some additional options.

94b83c4e733d15a486042ad36741ee0a_original

“We refer to it as a desktop manufacturing space. While the system is user friendly, its capabilities are much more precise than consumer models currently on the market. But the key differentiator for BoXZY is its interchangeability,” the duo explains.

In essence, BoXZY is a dual-extruder FDM 3D printer that can be quickly interchanged with a solid 1¼ horsepower Makita router, transforming the machine into a powerful CNC mill or a laser etcher in a moments notice. Using these heads, any Maker can craft a block of aluminum, hardwood or plastic into more complex designs. The whole operation is housed inside a solid aluminum body, and assembled with stainless steel hardware to ensure its stability and durability throughout all applications.

adef6e63aa84d7266a4b2bc6ec7f7df7_original

Moreover, the triple-threat tool is designed to be completely modular and hackable — something Makers of any level will appreciate. To power up and create its four micron resolution, BoXZY drives all three axes with industrial ballscrews, which are firmly situated in its sleek, black anodized aluminum body.

As a CNC mill, BoXZY can handle intricate shapes in all kinds of materials. To get started, users simply pull off the magnetically coupled 3D print platform to expose the pre-drilled fixture plate and attach their spoil board, fixture plate or clamps. Additionally, BoXZY boasts a 2000mW laser engraver that slices through balsa and other thin woods eagerly, and will put finishing touches on hardwood, leather and plastic with incredible precision.

570ab9fd71ba530d73674899863e56b9_original

And when it comes to 3D printing, BoXZY is billed as a top-tier device as it complements its mill and laser perfectly. Indeed, Makers can easily and accurately print complex shapes with fine detail using a wide-range of filaments like PLA, ABS, PVA, Ninja-flex, ABS, and even nylon. All together, anyone can now devise shapes that would have otherwise been impossible from other forms of manufacturing.

What’s more, Makers can CNC mill, laser engrave and 3D print without ever leaving the control software. That’s because BoXZY utilizes a simple, intuitive interface that caters to everyone from novices to pros. For milling, BoXZY uses AutoDesk’s 123D toolpath generation, and can execute G-code created by most commercial CAM programs.

Interested? Head over to its Kickstarter campaign, where the duo is currently seeking $50,000. If all goes well, units will begin shipping in November 2015.

RenderBot is a DIY 3D printer with a focus on quality


RenderBot is a high-quality, inexpensive and easy-to-build 3D printer for Makers of any level.


It’s no secret that new, do-it-yourself 3D printers are a dime a dozen these days. Yet, it seems like a majority of these kits are designed with the goal of packing as many components into the machine as humanly possible, while still maintaining a low-cost and compact form factor. In reality, this leads to a device with limited capabilities and a number of malfunctioning parts, which ends up costing you a lot of more money in the long run. After experiencing the aforementioned problems first-hand with a variety of crowdfunding printers, one Springfield, Illinois startup has set out to change that trend with their RenderBot. This DIY 3D printer kit is not only inexpensive and easy-to-assemble, but more importantly, was created with superior quality in mind.

7dfc33c1da3b350cb6d9eac92cf0e6e1_original

Tailored to both novice and advanced Makers alike, the RenderBot comes with a completely genuine, all-metal E3D hotend right from the start. This provides users with the durability and flexibility necessary to print with any plastic filament currently available. In addition, the printer is based on an RAMBo controller board (ATmega2560/ATmega32U2), which enables users to upgrade their printer at a later date should they want to add on non-essential components such as a heated bed, an LCD, a dual-extruder or an external temperature sensor.

“This printer is easy to assemble as well. With most printers, wires are difficult to work with. Once they are attached, you have to disassemble the entire machine to rework them. The motors on the RenderBot are all detachable from their wiring, which makes it incredibly easy to install them without having to worry where their wires go ahead of time. Once you are ready, you just plug one end into the motors and the other end into the controller board,” the team writes.

b30487b8fbc07cf3df5ccca638962130_original

RenderBot is comprised of a sturdy steel frame in the form of two connected right triangles. This allows for the front of the printer to be relatively transparent and easily accessible for part retrieval and inspection. What’s more, users will never have to reach into the device or bend over to see the progress of a print.

  • Printer size: 14.5″ x 16.5” x 17.5″ (422mm x 367mm x 448mm)
  • Build volume: 10” x 10″ x 10″ (254mm x 254mm x 254mm)
  • Layer resolution: 0.32mm – 0.2mm
  • Print speed: Stable at 60mm/seconds (can go higher)
  • Filament type: ABS, PLA, nylon, flexible, wood, ceramic, bronze, polycarbonate, HDPE, PVA (1.75mm)

Interested in a RenderBot for yourself? The printer currently comes in one of three different ways, either as a standard kit, an easy kit upgrade or fully-assembled. Head over to its official Kickstarter page here, where the team is currently seeking $65,000. Pending all goes to plan, shipment is slated to begin in June 2015. (And we’ll have to admit, between smashing objects and lighting things on fire, we couldn’t help but watch the entire crowdfunding video!)

This 3D-printed, Arduino-powered device can treat hypothermia


A team of students has created a portable heated IV device for extreme climate situations and high-altitude climbers.


Hypothermia is a serious danger to high-altitude climbers. When a patient suffering from hypothermia is brought to a hospital for medical assistance, a doctor typically begins treating the patient through the use of a heated IV. Injecting warm saline solution into the body raises the patient’s core temperature along with properly hydrating them. However, often times those suffering from hypothermia don’t have immediate access to medical assistance.

IMG_1439-X3

Cognizant of this, a team of students at NuVu Studio have created a portable heated IV for extreme climate situations and high-altitude climbers suffering from hypothermia, or dehydration for that matter. This product, which they call Backcountry IV, is not supposed to heal a person completely; instead, it is intended to serve as a temporary aid to prolong the user’s life until they can receive actual medical help.

The students were able to bring the idea to fruition, which resembles that of a mini flashlight and lantern, through the use of 3D printing. The device works by purifying water using a 3D-printed cap with built-in UV lights, which connects to another compartment containing ceramic resistors that heat the liquid between 104-106°F.  Once this is done, the water flows through the IV tubing until it reaches the needle that is clipped onto the specialized, 3D-printed cuff resting on a hiker’s forearm. The canister also holds several other necessary parts like a salt tablet and an infrared light vein finder.

cuff-GIF-final

“The importance of the product is clear — it could be the defying factor of a high altitude climber’s survival. Without the Portable Warm IV, a person could possibly die of hypothermia on the mountain but with the IV, the chance of his or her core body temperature warming enough to prolong the survival long enough to receive medical assistance is likely. There are no existing products that are capable of helping high altitude mountaineers let alone in extreme conditions return their body to a normal temperature. Since hypothermia is such a serious threat to the lives of mountaineers, it is crucial to have a device that would keep them alive at high altitudes and dangerously cold temperatures. The portable warm IV would bring the user fundamental and pragmatic medical attention immediately, making it a life-changing product… Literally,” the team writes.

The students constructed each part of this device using an ATmega2560 powered MakerGear 3D printer, with the exception of the actual IV and electronic panel, where the Arduino Micro (ATmega32U4) sits.

IMG_1191-X3

“This process began by simply hooking a 3.9 ohm resistor up to the Arduino and attaching the resistor up to the temperature sensor in order to read the heat that the resistor was giving off. Initially there was not enough power to make the resistor heat up to the optimal heat. Many alterations were then made over a span of three days. The result was four resistors soldered in series hooked up to an 11 volt lithium polymer battery. This battery provided the correct amount of power in order to heat the resistors up to the correct temperature.”

3D printing allows the blind to ‘see’ famous paintings


The Museo del Prado has launched its first initiative focused on visually impaired visitors and based on innovation and 3D printing.


Go to any museum throughout the world and you will surely find signs advising you “not to touch” any painting. However, a new installation inside Madrid’s Museo del Prado wants visitors to do anything but. In fact, visitors are encouraged to touch and experience a number of famous pieces. That’s because the museum has launched a first-of-its-kind project that is designed to give the blind (or those with limited visibility) an opportunity to create a mental image of artwork by merely feeling it.

paintings-for-the-blind-1

The unusual exhibition, which is aptly dubbed “Touching the Prado,” is comprised of six replicated pieces from the museum’s famous collection, all of which were brought to life using 3D printing technology. These include Goya’s “The Parasol,” “A Still Life” by van der Hamen,“Apollo in the Forge of Vulcan” by Velázquez, “Noli Me Tangere,” and Correggio’s painting of Jesus meeting Mary Magdalene.

Now through June 28th, visually-impaired visitors will have the opportunity to obtain a heightened degree of artistic-aesthetic-creative enjoyment in order to explain, discuss and analyze displays in the Prado. Beyond the 3D images, the exhibit will include didactic material such as text in the form of braille, audio guides and opaque glasses aimed at facilitating the complete experience.

07prado-3-articleLarge-v2

The idea that blind people should have the ability to experience 3D-printed copies of paintings, however, goes significantly beyond just these efforts to make art accessible. According to The New York Times, this latest installation is one of the most sophisticated yet with aspirations of unlocking the beauty of the visual arts for those unable to see them. Among other museums who’ve also sought to enable a tactile exhibits include The Metropolitan Museum of Art in New York, the National Gallery in London, The Louvre in Paris, Museo Nacional de San Carlos in Mexico City, and the Denver Art Museum.

Similarly, Spanish creative agency Lola and Pirate 3D launched a social experiment last year, which gave the blind the chance to literally touch their most candid memories and photographs through the use of 3D-printed, tactile printouts.
