4. Israeli Air Force Begins Using 3D Printing Technology
A number of militaries around the world have recently began researching the role 3D
printing could potentially have within everyday requirements such as replacement parts.
The Israeli Air Force (IAF) has recently announced joining the fray with the purchase of an
industrial-scale 3D printer from a US 3D printer manufacturer. The IAF is seeking to produce
a number of aircraft and unmanned aerial vehicles (UAV) components via 3D printing.
They will begin by printing plastic-based 3D prints up to a meter in length, but plan to
switch over to metal parts in coming stages of implementation.

Apple Files for Patent on Handheld 3D Scanning Stylist
Tech giant Apple was issued a patent last week, entitled Texture Capture Stylus and
Method, for a new type of stylus which can capture 3D data of objects for possible
creation of 3D printable models. In other words, the stylus acts as a sort of 3D
scanner, with the tip transmitting light onto a surface to act as a lens for a camera
or image capturing device. The patent was originally filed in early 2014, and signals
a potential entry point into the 3D printing word for the tech company.

5. Nike Develops 3D Printed Helmet to Keep Athletes Cool
A group of designers at Nike have unveiled a next-generation cooling system developed for U.S.
Olympic champion and decathlon world record holder Ashton Eaton. Any advantage that speed
up recovery times for decathlon competitors can have a significant impact on an athlete’s
performance. For Eaton overheating was a challenge, leading him to ask Nike why it felt great to
pour a bottle of water over his head after a long run. It turns out that the head and face, according
to Nike scientist, have two to five times more sensitivity than other body surfaces areas. The design
team went about creating a specialized mask that would perfectly fit Eaton using 3D scanning and
3D printing. The team created a hood that retained cool water, while securely stay in place.

3D Printing Changing the Lives of the Elderly
It is no surprise that as people age, they begin to experience difficulty accomplishing simple
everyday task. To address these problems, Japanese Designer Tatsuo Ishibashi has turned to 3D
printed to create a line of products focused on assisting the elderly and people who suffer from
diminished physical functions. In his shop, mizulabo, Ishibashi designs simple lightweight and low
cost solutions to a variety of challenges. One example is a 3D printed tool that assists people to
write with ballpoint pens, as well as a tool to help users remove caps and tabs from plastic bottles
and cans. Ishibashi’s creations are a perfect example of the potential use of 3D printing to better
lives.

6. Using 3D Printing to Create a Battery Tester
3D printing can be used to solve a myriad of daily problems, large and small. There are
countless examples of this on the internet. Most recently the Ruiz Brothers at Adafruit have
taken this axiom to heart, releasing a array of useful projects for users of any skill level. Their
most recent project was developing a simple 3D printed battery tester. The brothers sought
to create an easy and useful project for beginning designers to showcase the ease and
overall usefulness of 3D printing for everyday life.

Breakthrough In self-assembly 3D Printing
A research team led by Dr. Ido Bachelet at the Institute for Nanotechnology and Advanced
Materials at Bar-Ilan University in Israel have developed an algorithm that allowed 18 tetrahedral
bricks to self-assemble into a larger 3D cylinder. The team then found that high frequency
vibrations can be used to aide bricks in self-assembling into a large 3D object, potentially
changing the future of consumer product assemblies. The idea of self-assembly is that many small
and disordered 3D printed parts combine on their own to create something much larger, allowing
a variety of objects to be created from the same elementary building blocks. The next step of
research will be refining how the parts stay in place to be used to assemble reliable and
functional products.

7. Student Develops 3D Printed Drone to Monitor Crops
Farmers have been taking aerial readings of crops to monitor and improve crop yield since the
down of aviation. Recently drones have been deployed to take the aerial readings, taking photos
that display near-infrared readings of how plants are absorbing sunlight and their photosynthesis
levels, data that can be used to verify the current health of their crops. The only problem is that
these services are expensive, and therefore out of reach for most non-commercial farms. That is,
until Quesney Nevarez, a Mexican electronics engineering student, began investigating how 3D
printing and off-the=shelf parts can expand crop monitoring to lower income farmers. Nevarez
worked on the project in Ottawa at a program that finds new applications for drone technology.

Creating a Wind Powered USB charger with 3D Printer
Anthony Dorsa, a sophomore mechanical engineering student at Binghamton University, has
developed a 3D printed device that uses wind power to act as a USB charger. Dorsa was inspired
by Makerbot’s Catch The Wind challenge, a competition among 3D designers to create a 3D
printed model that harness the power of wind. After experimenting with a variety of wind turbine
designs, Dora realized that smaller sized turbines typically require very little wind to start spinning,
and that single directional turbines produced optimal power, while minimizing overall design
complexity. He has since released his plans to the public, showcasing the overall potential of 3D
Printers.

8. Apple Announces Update to Enable Basic 3D Printer Support
This past week Apple announced an update to their Common Unix Printing Systems
(CUPS). With the release of CUPS version 2.1, the Apple OS supports basic 3D printers. This is
something that simply was lacking in previous CUPS versions. While the OS will only support
basic 3D printers, with no built-in filters, it bodes well for mainstream adoption of 3D printers
and 3D printing related devices, as more and more technology companies join the 3D
Printing revolution.

Chinese Researchers Make Breakthrough in SLA 3D Printing
Scientist from the Guangzhou Nansha Additive Manufacturing Technology Research Institute
announced a new 3D printing technique that can be used to create detailed porcelain and
other ceramic objects in mere minutes. Xu Xiaoshu, the Institutes director, argues that this new
process represents a immense breakthrough in the field of traditional SLA 3D printing technology,
resolving the three main issues that plague the SLA 3D printing process: high liquidity requirement
of material, scraping pieces post print, and slow printing speed. The new technique will reduce
cost, almost double 3D printing speed, and capable of printing high precisions objects of up to
800 by 400 mm.

Showcasing some of the most interesting applications of 3D
Printing, from the amusing to the artistic to the innovative

12. 3D Printed Exoskeleton for Stroke Victims
! Daniel Levy, a design engineer, has
created a 3D printed open-source
exoskeleton that helps stroke victims
suffering from lack of finger movement
regain mobility in their hands.
! Levy and a research team of four
members created the device which
uses the motion of the wrist to open
and close the fingers.
! The team was inspired by a friend’s
brother who suffered a spinal injury and
was unable to regain hand function.

13. 3D Printing Design for Platform Jack
! The Seattle-based company intentional3D has
released Platform Jack, one of the most popular
and most downloaded designs online.
! The company released a design which is
printed in one single piece, that features several
movable parts, and requires no support
material, while at the same time acts as a fully
functional product right off the 3D printer print
bed.
! The Platform Jack essentially acts as a
traditional ‘jack’, lowering and lifting a base
with a set of arms by turning a threaded knob.
