3D Printed Plaster Cast to Replace Older, Itchier Casts

Posted in 3D Printing

Though plaster casts have long been an important tool for orthopaedic healing for centuries, they are not free of foibles. Sweat, dirt and restricted ventilation are known to cause not just discomfort but also infections. A 21st century 3D printed alternative is set to change all of that. MediPrint, a Mexican startup by UNAM University students has recently been involved in some impressive work on NovaCast, a 3D printed alternative for plaster casts. Weighing as much as ten times less than a plaster, NovaCast can also be washed, thus solving the long-standing problem of hygiene.

The material used for plasters is hygroscopic, absorbing sweat and providing bacteria a fertile ground owing to its lack of ventilation. In case of extreme scenarios, infections can result in loss of limb; sometimes bones are not able to heal properly due to badly placed plaster casts. Naturally, NovaCast offers a great alternative.

Not only is NovaCast customizable, unlike plaster casts it doesn’t need to be removed while bathing. It leaves no room for bacteria to thrive. Interestingly, the cast is printed by generating by an algorithm as opposed to CT scan data usually used for 3D printing medical accessories. While this certainly saves on hardware costs for doctors, it also means medical professionals can focus solely on their patients and do not have to get their hands dirty with CAD and other software required for printing otherwise.

The NovaCast is a thin cast and can be printed in under four hours, depending on the size of the limb. While it is still in the developmental stage, the startup recently landed a major boost on fondeadora.mx, a crowdfunding platform, where it raised over $8,000 to expand its 3D printing capacity using a high volume 3D printer.

3D Printed Robots Walk Their Way to Success

Posted in 3D Printing

Pushing the envelope a little further, a group of researchers at MIT’s Computer Science and Artificial Intelligence Lab has developed an ingenious method to 3D fully functional robots. The robots, which are made from both solids and liquids, require just a single battery and motor; they can then practically walk right off the printing table.

The team utilized a process they call “printable hydraulics” for the printing process, and hope to make a breakthrough in rapidly fabricating machines. For the process, researchers used a 3D Inkjet printer for dispersing materials measuring half the human hair. When printing the structure, the printer puts photopolymer material on the surface of the print, hardening it with a UV light while leaving the liquid portions untouched.

While building robots is largely a labour-intensive and time-consuming process otherwise, 3D printing offers a break from it. But, during the process, the researchers were not able to find a way of incorporating robust force-transmission elements into a 3D-printed object. After a lot of trial and error, they were able to place a useful liquid/solid combination for creating a functional robot in one go. The process produced a six-legged robot that can walk using the power of 12 hydraulic pumps printed inside it.

The 3D printing process lasted for about 22 hours. The team subsequently installed a battery and motor inside the robot which then allowed it to move on its own. MIT now plans to expand the scope of its innovative hydraulic printing technology and improve on the method to cut down the time required for the process.

Previously, 3D printing was only done with solid materials but the introduction of liquids into the process makes complex designs possible while cutting down on the time required.

3D Printed Electronic Egg to Spy on Vulture Nests

Posted in 3D Printing

The International Centre for Birds of Prey (ICBP) recently expanded the scope of 3D printing technology to include the animal kingdom in the list of the beneficiaries. Using micro-controllers along with 3D printing, ICBP is trying to learn about an endangered species of vulture and what it needs to survive.

In a bid to prevent the extinction of the bird species, researchers have created 3D printed vulture eggs with hidden micro-controllers to pass off as real in a nest. ICBP partnered with Microduino for the venture, which specializes in Arduino compatible modules and micro-controllers.

After a lot of research and development, the Microduino team was able to produce a 3D printed vulture egg called EggDuino. The shell was made using SLS 3D printing with a PA2200 nylon material and contains a wood enclosure that holds the electrical components. The egg was then equipped with a Microduino core, a Bluetooth Low Energy module, a multisensor 10DOF module that included a gyroscope, accelerometer, a magnetic field strength sensor, and a barometer, fourteen DS18B20 temperature sensors, and a SHT21 humidity sensor. The egg module is powered by a 1800-miliampere/hour battery and is enabled with transmission of its data to a WiFi enabled Raspberry Pi.

When the 3D printed eggs are created and assembled, they are placed inside the vultures’ nests with the terminals placed away from the animals to receive data transmissions through Bluetooth. The terminal can also monitor weather conditions outside the nest and save its data. Using this innovative technology, researchers are able to use the printed eggs’ data to ascertain their temperature gradient.

Once the project is finalized, the ICBP will officially deploy its 3D printed eggs in India and Africa within the next month.

3D Printed Device Detects Anaemia in Seconds

Posted in 3D Printing, CAD

Adding to 3D printing’s growing list of impressive feats, researchers at Kansas State University recently developed a 3D printed device that can detect anaemia within seconds. The low-cost diagnostic device works when paired with a smartphone app and is beneficial to people with only limited access to healthcare. It can also be a revolutionary point-of-care solution for the developing countries, where more than half the pregnant women and preschool children are reportedly anaemic.

The diagnostic device is made of 3D printed plastic slides that contain microfluidics. Users only have to add a drop of their blood on the slide and attach it to the smartphone. Within 60 seconds, the app can produce an accurate result using a color scale based test. Just as is the case with pregnancy and glucose tests, the process does not require a physician to make the diagnosis.

The device was developed by Kim Plevniak, a Master’s student in biological and agricultural engineering at the University and Mei He, assistant professor for the same course.

The 3D printing technology has enabled the researchers to keep production costs low. The team spent over a year designing a relatively inexpensive 3D printed prototype for the device. Recently, they also won the approval to conduct clinical tests on patients from the University of Kansas Medical Center, allowing them to further improve on the device and optimize it for real-world diagnostic performance. They have also applied for an invention disclosure with the Kansas State University Research Foundation for the proof-of-concept device.

Once fully developed, the 3D printed device will help diagnose the disease and save millions of lives worldwide, proving the real-world applications of 3D printing yet again.

3D Printed Vertebrae A First in Surgery

Posted in 3D Printing, CAD

A surgery involving a 3D printed organ recently created history, once again reminding us of how 3D printing technology is already affecting our lives in significant ways. An Australian neurosurgeon performed the first surgery of its kind by replacing a cancerous vertebrae in a patient with a 3D printed one.

Ralph Mobbs performed the surgery late last year on a 60-year old patient suffering from a rare type of cancer affecting the bones in the spine and skull, called chorodoma. The patient could potentially have been left paralysed had the 15 hour surgery failed. Replacing the patient’s vertebrae was a tricky feat because of their position – any implants had to be a perfect fit. To tackle this issue, Mobbs went for an unusual approach; he decided to 3D print the replacements. He closely worked with Anatomics, which manufactures medical support surfaces and positioning devices, to design the titanium implants.

The patient’s tumor is removed but he will require rehabilitative treatment before he is able to eat and speak on his own. Other doctors and scientists are also increasingly experimenting with 3D printed body parts. Recently, scientists proved the feasibility of the technology by growing a 3D printed ear on a rat’s back, a procedure they claim can be extended to human transplanting. Anatomy students at the Australian Monash University have also started training for implanting 3D printed organs.

Before the surgery took place, the company also printed anatomical models identical to the patient’s head for Mobbs to practice on. In Mobbs’ words, 3D printing is “the next phase of individualised health care”. He believes medical science is pushing boundaries by incorporating 3D printing technology at this scale.
