#Titan Robotics announces new high-quality large-scale 3d printer called The Atlas May 21, 2015 By Simonalthough wee been seeing dozens of new 3d printers and material options in recent memory,
Founded by mechanical engineer Clay Guillory who calls himself mechanical engineer by day, and a mechanical engineer by night, Titan Robotics focuses on doing one thing and one thing very well:
Among other applications that Clay has used his 3d printing know-how towards include prosthetic hands -which started as a request from a mother
whose 8-year old boy was need in of a low-cost solution Titan Roboticsatlas 3d printer was named after the famous Greek god who was known for fighting alongside the Titans
According to Clay, he strength of this Greek god is an accurate depiction of the strength
the Atlas has proven to be a highly-accurate 3d printer that is capable of printing large prototypes reliably over time.
According to the company, one beta user documented printing an extremely large accurate and functioning prototype with a total recorded print time of just over 200 hours.
and machined steel that are literally capable of lasting a lifetime. The printer can be designed to any desired build space of up to 6x 6x 4 For those looking for more customized options
Titan Robotics is capable of scaling the machine, too. As for materials, the Atlas is capable of running nearly any 3mm plastic filament with extreme precision
said Founder and CEO Clay Guillory. e fully expect this printer to be a game changer in the 3d printing industry. hile the Atlas may share many of the same attributes of a well-built desktop 3d printer,
The Atlas starts at a base price of $15, 000, however for most small or medium sized businesses who regularly find themselves needing to 3d print large prototypes,

#Help the nonverbal speak: Dustins Words communication tool brought to life via 3d printing May 21, 2015 By Simonalthough wee no doubt seen how additive manufacturing has been a breakthrough for creating low cost and customizable prosthetic devices for both humans and their four-legged friend alike,
when the technology is combined with various electronics and built with an open source mentality, the possibilities are seemingly endless.
Recently, additive manufacturing played a significant role in the development of a revolutionary new medical device that,
Dustin, Experience Designer Matt Reamer ustin Wordsis an open source invention that helps people who can speak
whether he had a headache, was hungry or he simply wanted to say love you
caregivers and teachers who help them every day,"stated Reamer, cofounder of Solve For one.""We're also going to open source everything we dorom our code, to the 3-D models, to the platform itself,
so that in addition to being able to purchase a preassembled device, anyone can print and assemble a device of their own."
After trialing multiple technologies, the team has decided to build off of Particle. io cloud-based platform that enables users of Dustin Words to be able to update the functions of the buttons using a variety of online services including IFTTT, Twilio
, Node. js, PHP, Python, or Spark. js. According to Matt, Spark. js has been particularly useful, because it gives us the ability to customize messages, delivery methods (SMS,
and technologies that can handle a range of people with different disabilities that make communication difficult.
Among others, these include people with nonverbal autism, people with nonverbal learning disorders, people with ALS, people with Rett Syndrome,
people who have suffered traumatic brain injury, stroke victims and anyone else with limited mobility. ur goal is to create an affordable, customizable,
open source device and platform that families can use to meet their unique communication needs, says Matt. any families who already struggle with financial burdens due to health-related issues end up spending thousands of dollars on assistive communication tools.
We want to offer an alternative communication tool that augments a family daily routine by providing an easy way to say the things that matter most
and can costs upwards of tens of thousands of dollars. Just like many of the 3d printed prosthetic devices wee seen,
Matt wants to make his entire project open source for everybody to be able to have access to.
This includes everything from the 3d model files that can be used to build the housing to the code and the platform itself.
but they will also serve as inspiration as Matt continues to further iterate on Dustin Words to make it the the penultimate affordable, open source,
From user testing, to device sketching and iteration to application development everything we do will be shared on open source platforms
so that we can engage an impassioned global community. As we document our process, we invite you, our viewers, backers,

#Chinese doctor removes kidney tumor with the aid of a 3d printed replica May 23, 2015 By Simonwhile wee seen how developments to additive manufacturing technologies have helped both bring down the cost of getting something 3d printing as well as delivering results faster,
one of the more significant contributions wee seen the technology make hase been in the health and medical sector.
While wee still a few years away from seeing 3d bioprinting technologies that are capable of 3d printing entirely-new, 3d printed organs such as livers or kidneys,
we have been seeing significant contributions from technologies that exist today on desktops around the world.
wee seen how various medical imaging data including CT SCANS and MRIS, among others, have been used to create digital 3d models that are printed then out and used as a replica of a patient actual body part for the sake of practicing a surgical procedure in advance of an operation
More recently, doctors at the Xiangya Hospital of Urology at Central South University in China were able to leverage 3d printing technology in an effort to help successfully remove a tumor from a 60-year-old woman kidney.
Thanks to the use of a 3d printed model in advance of the surgical procedure, the doctors were not only able to remove the tumor-but also save the kidney itself;
Because the left renal tumor was located directly next to the renal hilum-an area of the kidney that features many vital arteries
and veins-the surgery would have called for a removal of the entire kidney in most cases to avoid the risk of causing further damage to a patient.
Dr. Qi Lin, chose to use 3d printing to assist in the process of planning the surgery. To create the accurate replica of the patient kidney
Dr. Qi Lin took a series of CT SCANS of the patient kidney, tumor and surrounding area
the doctors were able to pinpoint necessary locations for incisions and other details that would ultimately lead the surgery to success. On May 11th,
Dr. Qi Lin-along with his medical team-performed the 90-minute surgery and were successfully able to remove the tumor while keeping the kidney intact with patient.
In addition to helping reduce the amount of blood loss to just 50 ml during the procedure
the use of the 3d printed replica also dramatically reduced the length of the surgery; what used to take hours only took a mere hour and a half. ith this new 3d technology,
when aided by the surgeon, it creates a situation where eeing is believingadded Dr. Qi Lin. his is true from multiple dimensions,
and allowed us to pinpoint the tumor, the arteries and the surrounding kidney tissue before surgery,
practice the surgery and then decide on the correct path and operation to perform. Posted in 3d printer Applications (adsbygoogle=window. adsbygoogle.

#Procter & gamble jumps into 3d bio printing with grant program in Singapore May 26, 2015 By Simonit no secret that one of the most exciting developments in the additive manufacturing industry has been in the advancements in 3d bio printing-the printing
of living human tissue. While wee been hearing promises about the technology from a variety of companies over the past few years,
2015 has been a reakthroughyear that has shown significantly more promise for bio printing technologies-including the announcement of an upcoming surgery that will see a 3d printed thyroid gland be implanted for testing-a first of its kind.
The bio printing process which works by taking cultured human cells and forming a bio-ink for extruding into layers of scaffolding that living tissue is harvested then from,
has been performed largely in laboratories and schools with a focus on bioengineering applications that utilize living organs and other human tissues.
But in addition to being able to create living organs and human tissue that can be used as replacements for failing systems in humans and other animals,
the printing can also be used to replace what has largely been a controversial practice for years now:
the testing of products on animals. While tests for everything from shampoos and makeup to various household cleaners have been conducted on animals to test their safety,
bio printing technologies will allow for companies to use synthetic living tissue as needed. Among other companies that have been actively looking into how they can leverage bio printing to their advantage is none other than Procter & gamble-the largest consumer goods company in the world.
and Tide to Bounty and Crest-is launching a grant competition in Singapore that asks those in academia to submit research proposals on 3d bio printing applications that would be of relevance to the consumer goods brand. e want to look at the possibilities of bioprinting.
It definitely a very strong emerging area, said Professor Elena Lurie-Luke, head of Procter & gamble Global Life sciences Open Innovation.
-whose interest in the technology has gone so far as to partnering with bio printing startup Organovo to develop 3d printed skin.
and interested in new tools then bioprinting should very much be on their horizon, added Ms Lurie-Luke.

#Bucktown Polymers water soluble Rinse Out 3d prinintg Resin (ROR) could replace lost wax casting Jun 1,
2015 By Simonwhile wee been seeing an ever-increasing range of 3d printers including both those that incorporate additional manufacturing processes as well as those that aim to be more minimal and low-cost,
More recently, researchers at Bucktown Polymers have developed a new type of 3d printing material that cures rapidly
Illinois and produces a range of products including adhesives, coatings, inks, resins, composites, photopolymers and other materials for manufacturing-found that the materials have unique uses in additive manufacturing
Among other benefits of the ROR (Rinse Out Resin) include its ability to drastically reduce the amount time required to produce as an investment casting material.
Existing polymer or wax-based offerings have up to a 12-hour long burnout process whereas the ROR is capable of being rinsed with water in a matter of minutes.
it is also eliminating the problem of unintended patterns that can be created from other materials due to polymer expansions or leftover ash and residue.
or a complicated user experience that could deter would-be users. With this in mind, the water soluble materials can be formulated for compatibility with many existing desktop 3d printers
and more complicated industrial additive manufacturing machines including SLA, DLP, Inkjet and powder-based processes. Perhaps its most significant use though will be lost in replacing wax processes
Those interested in finding out more about Rinse Out Resin can head over to Bucktown Polymers.

#Swedish start-up CELLINK develops the first universal 3d printable bioink for 3d bioprinters While lives are already being saved by high-level 3d printing in academic hospitals all over the world,
most of these cases involve 3d printed implants and replicas used to prepare for unusual surgeries. Doubtlessly, the real 3d printing revolution in the medical world is yet to come:
bio 3d printing. Involving special bio-inks made from biocompatible polymers and cells, these could be used for 3d printing just about everything in the human body, from cartilage, to bone structures and theoretically even entire new organs.
And now a Swedish start-up called CELLINK has developed a bioink that could make this medical revolution happen as soon as possible.
For the current problem is this: scientific progress with these bioprinted materials is agonizingly slow.
Various institutes and hospitals all over the world are experimenting with new materials and applications, but most won result in practical solutions for years.
And that a problem, as an estimated 21 people waiting for organ transplants are dying every single day.
And this is exactly where CELLINK comes In this Swedish company lead by Erik Gatenholm and Ivan Tournier have developed
what they are calling the world first universal bioink, with optimal biocompatibility and printing fidelity.
Suitable for a large variety of bioprinting applications, this innovation could vastly reduce the time companies
and research institutes are spending on developing suitable bioinks and human tissue structures themselves. In short
it brought the bioprinting revolution so much closer. As the two entrepreneurs explain to us, both have an extensive background in biotechnology.
At age 18, Erik Gatenholm started his first medical device company, manufacturing meniscus implants and other implants, such surgical meshes for ventral hernia repairs and wound dressings.
Gatenholm is currently finishing his Master degree in Innovation and Industrial Management at Gothenburg University in Sweden.
Ivan Tournier, meanwhile, has an extensive background in the 3d bioprinting field and cartilage tissue regeneration
and is currently finishing his MBA degree at Isam-Iae University in France. And with their bioprinting goals in mind
CELLINK is releasing the world's first 3d bioprinting'Start-inkkit, which can be used to quickly develop bioink.
The commonly used and much slower method involves 3d printing bioink and another polymer like material together slowly,
but this kit can simply be mixed and subsequently 3d printed. The effectiveness of this approach was explored in one of their papers in the journal Biomacromolecues.
Using their nanocellulose-based hydrogel, they reported proliferation and collagen type after just 21 days of culturing.
Once the printed structure is crosslinked, it also gains very useful properties such as being easy to handle,
resistant to shocks and so on, making it very useful for bioprinting applications The next step for this promising start-up is to apply 3d bioprinting to a wider range of human tissue models,
sizes and functions from models with mechanical grips to bionic sensor action none of them are advanced enough to be operated with your mind.
the young man from Colorado has developed a sensor-based prosthetic that doesn, like the Myoware, rely on muscle contractions,
so it kind of works kind of like a muscle sensor in that it picks up small electric discharges and turns that into something you can actually read within software,
These brainwave-based prosthetics are also remarkably easy to operate through a wireless headset. good example is had we actually an amputee use the wireless brainwave headset to control a hand,
so the learning curve is hardly a learning curve any more, Easton added. The algorithms operating the hand have incorporated even options for smaller and larger weights,
making use largely intuitive. An early prototype. Easton is currently on the fifth iteration of his robotic prosthetics, all of
accelerometers to track your wrist and elbow, and then an IMU sensor as well to track your bicep rotation as well as your shoulder movement,
and that gets all translated wirelessly to the robotic arm where it will copy what you do,
while all designs are open source with the express purpose of making it suitable for any type of situation, amputation or genetic defect.
because we this open source, we want someone that has a 3d printer, or very little printing experience, to be able to replicate this,
to be able to use this for new applications, to be able to adapt it into new situations,
but even in bone disease, changing toe forms and other complications over time, chief advisor of Jiaodukeji, Xu Chaoyi, explained. his is
Within just three seconds, the scanner gathers all the necessary data for a digital rendering. Selecting one of the available shoe shapes (there are ten available designs at the moment),
#The 3d printed Peek smartphone adapter helps diagnose eye disease in developing countries While we come across so many interesting 3d printed applications,
the ones with the greatest impact are surely those that help doctors, save lives and improve the quality of life of the poor and underprivileged.
And in that respect, the 3d printed Peek short for the Portable Eye Examination Kit developed by a team of British ophthalmologists,
Perfect for use in third world countries and remote locations far from medical help, this kit essentially consists of a 3d printed add-on for smart phones that can be used to treat preventable blindness.
Thanks to this successful backing, the Peek can now also be ordered pre by doctors. This project has been devised by Andrew Bastawrous, Stewart Jordan, Kate Tarling and Mario Giardini,
it has the potential to help more than 39 million people around the world who lack access to basic optical healthcare. 0%of this blindness is avoidable,
Think about eye diseases like cataracts, glaucoma and others. While equipment for diagnosing such diseases already exist
they are heavy, expensive, fragile and require extensive training not at all suitable for use in remote regions without proper electricity.
And that exactly where the 3d printed Peek Retina comes in. t a clip-on camera adapter that gives high quality images of the back of the eye and the retina.
This helps us to diagnose eye diseases, ready for treatment. Peek Retina combines both a traditional ophthalmoscope and a retinal camera in a mobile phone, providing a portable,
affordable and easy way to carry out comprehensive examinations, they wrote. Suitable for just about every smartphone
it an excellent 3d printed solution. Due to extensive testing and prototyping, this 3d printed smartphone adaptor should be ready for use in October of this year,
though more field studies are planned in countries as Tanzania, Malawi and Kenya. However, earlier tests have produced already excellent results. hese trials
not only scientifically validate the quality of images Peek provides in comparison studies, but make sure it works effectively in the context of specific locations, the local healthcare system and for both novice and expert users.
It just another example that proves that 3d printing isn just about toys and fun but also about lives and the quality of life everywhere i
#MIT professor develops highly stretchable & tough hydrogels for 3d printing ears, noses & joints Jun 3,
While the ability to 3d bioprint an entire functional organ-such as a liver or even skin implants-is still a few years off,
Xuanhe Zhao, an MIT associate professor of mechanical engineering, along with colleagues at MIT, Duke university, and Columbia University published a paper in the industry journal Advanced Materials describing the process of 3d printing highly-stretchable and tough hydrogels into complex cellularized structures.
The tough biocompatible hydrogels are capable of being printed into complex and intricately patterned shapes that could ultimately lead to injectable materials for delivering drugs or cells into the human body.
Additionally, the unique process could lead to the creation of scaffolds for regenerating load-bearing tissues;
Previously, wee seen how medical researchers have been experimenting with something similar to create 3d bioprinted scaffolding for slowly introducing cells for a diabetic treatment process.
Hydrogels, which are defined by water molecules that are encased in rubbery polymer networks that provide shape
and are compared often to the biological structure of cartilage. While the development of the 3d printable hydrogels is certainly a breakthrough for Zhao and the rest of the team,
and be placed within the body using the hydrogel as a vehicle and support structure. Among other shapes that Zhao and the team were able to print with the new hydrogel include a hollow cube, a hemisphere, a pyramid, a twisted bundle,
a new ink for 3d printing of biocompatible-tough hydrogel, explains Zhao. ach material individually is very weak and brittle,
It like steel-reinforced concrete. n addition to being able to be synthesized with living cells, the hydrogels have also proven to have incredible elastic properties;
Zhao is so confident about the material that he believes it could even be used for soft robotic applications. his is really beautiful work that demonstrates major advances in the utilization of tough hydrogels
added David Mooney, a professor of bioengineering at Harvard university. his builds off earlier work using other polymer systems,
with some of this earlier work done by Dr. Zhao, but the demonstration that one can achieve similar mechanical performance with a common biomedical polymer is a substantial advance iit is also quite exciting that these new tough gels can be used for 3d printing,
as this is new for these gels, to my knowledge. osted in 3d printing Applications (adsbygoogle=window. adsbygoogle).

#Formfutura unveils Easywood Olive and Ebony, two new wood-like 3d printer filaments Jun 9, 2015 By Alecwith an internet full of 3d printable designs,
it obvious that you can create just about anything with a 3d printer. But in reality, most of us continue to limit ourselves to regular plastic designs made in either PLA or ABS filaments.
But did you know that you don have to spend thousands on a SLS or SLA 3d printer to add some variety to your prints?
It a unique mixture of 40%grinded wood particles in combination with the modified and proven easy-to-print binding polymers used for our Easyfil#filaments.
And while most nusualfilaments can be a bit tricky to work with, we are told that these Easywood filaments are just as easy if not easier to use as PLA,
which makes this filament a perfect match with all common desktop FDM 3d printers, the Dutch team says.
But of course you should play around with your own nozzle diameter, printing speed settings, and layer height to get the best response from your machine,
This works best on the roughest surfaces, so in this case layers might actually be your friend.
And with results looking that good and with prices (almost) in the same price range as regular PLA,

#Israel-based Utilight develops revolutionary new technique for 3d printing solar cells With the rise of various products that are aimed at creating
and harvesting sustainable energy, it comes with little surprise that many of the world top thinkers have been looking to additive manufacturing to develop unique solutions that could one day hold the answer for the future of clean energy.
Among others who have been actively using additive manufacturing technology to create more sustainable energy gathering systems include the Israel-based startup Utilight.
Since completing successful rounds of funding in 2012 made possible thanks to a series of government grants
and angel investors including the Israeli Office of the Chief Scientist, the engineers at Utilight have been actively developing a new type of additive manufacturing technology called Pattern Transfer Printing (PTP) that allows for the immediate implementation in the photovoltaic metallization process of c-Si solar cells.
According to the company, this implementation s designed for a quick and smooth assimilation within existing High Volume Manufacturing (HVM) production lines-using the same metal pastes
and production sequences and maintaining cell durability and bankability. Ultimately, the new technique is capable of increasing the efficiency of solar cells
while simultaneously reducing the photovoltaic manufacturing costs. The company is claiming that the the new PTP process is capable of saving traditional manufacturers up to $500
000 in silver paste and an additional $500, 000 in annual efficiency for a standard 40mw PV manufacturing line.
Based on these calculations, the company promises that those who are brave enough to use the process in their line will see a full return on cost in less than half a year-a very short span of time
with only an addition of one module with a minimal investment, providing savings of up to 70%in silver paste and an increased efficiency of up to. 4%.With a PTP printer,
the structure of a silicone wafer changed by dramatically increasing the amount of silver printed lines
Although the company itself is relatively young in the scope of solar cell technologies, its executive members bring a wealth of experience from material science, physics and engineering backgrounds;
Giora Dishon, the CEO & Chairman, alone holds over 30 years of experience in semiconductor and packaging processing
Although the solar cell industry may not be familiar to many, it is expected to grow exponentially as we continue to seek out alternative
and sustainable energy sources including the sun. triving towards a brighter future, (our) innovative technology aims to increase solar cell efficiency
and reduce material use, reducing the cost per watt of solar electricity, adds the company. s today leading photovoltaic cell manufacturers have reached the limits of conventional screen printing metallization processes for solar cells;
PV manufacturers must adopt new ways to promise substantial efficiency gains in order to be competitive within this thriving market. h
