Materialise is the world’s first additive manufacturing company to receive FDA clearance for diagnostic 3D printed anatomical models. FDA clearance supports the continued growth of point-of-care 3D printing facilities.

Belgian company Materialise is the first in the world to receive FDA clearance for software intended for 3D printing anatomical models for diagnostic use.

Leading hospitals are adopting integrated 3D printing services as part of their medical practices as they recognize the added value it brings to personalized patient care.

Materialise brings nearly three decades of experience in developing medical solutions that help researchers, engineers and clinicians achieve the desired patient outcomes.

In August 2017, the FDA announced that software intended to create output files used for printing 3D patient-specific anatomical models which are used for diagnostic purposes — is a class II medical device and requires regulatory clearance.

Materialise is the first company to provide software which conforms to these regulations and which can be used in U.S. hospitals in combination with a compatible 3D printer. Materialise Mimics inPrint software is used for pre-operative planning and the fabrication of physical models for diagnostic purposes, including patient management, treatment and surgeon-to-surgeon communication.

Important Milestone for 3D Printed Anatomical Models

Frank J. Rybicki, MD, PhD and Chief of Medical Imaging at Ottawa Hospital says:

“510k clearance is an essential component to ensure quality and safety in the practice of anatomical modeling in hospitals. This milestone for Materialise serves as a benchmark for the clinical implementation of 3D printing for physicians creating 3D models at the point-of-care.”

The FDA clearance supports the creation of point-of-care 3D printing facilities in hospitals. Anatomical models help surgeons to make better-informed decisions and to accurately plan their surgeries. They are also used to enhance education and communication between multidisciplinary teams and with the patient.

Hospitals recognize the added value 3D Printing brings to personalized patient care and to define treatment options. As a result, an increasing number of hospitals across the U.S. have integrated the practice of 3D Printing in their medical care and are creating point-of-care 3D printing facilities. Out of the top 20 US hospitals (as ranked by the US News and World Report), 16 have implemented a medical 3D printing strategy using Materialise Mimics technology.

“Materialise has nearly three decades of experience in developing certified medical solutions that create a better and healthier world,” says Wilfried Vancraen, Materialise CEO.

“The FDA clearance for our Mimics inPrint software will support the adoption of 3D planning and printing in U.S. hospitals and the creation of point-of-care 3D printing facilities.”

4D Printed Structures Could Improve Space Missions and Biomedical Devices

4D Printed Structures Could Improve Space Missions and Biomedical Devices
By Hanna Watkin

Tensegrity Objects

Researchers from the Georgia Institute of Technology developed tensegrity structures using 3D printers. The 3D printed objects dramatically expand when exposed to heat. 

It’s been somewhat quiet on 4D printing in 2017, but recently, things are unfolding again. Researchers from Georgia Institute of Technology have developed a method using 4D printing which could greatly improve space missions.

Essentially, 4D printing means a 3D printed structure which then changes in some way after the print is complete. More on 4D printing here: 4D Printing – All You Need to Know

In this case, the researchers used 3D printers to create objects which expand when exposed to heat. With heat, the 3D printed objects turn into tensegrity structures. This system relies on struts, or floating polymer rods, which are held together by cables. Glaucio Paulino, a professor in Georgia Tech’s School of Civil and Environmental Engineering explains:

“Tensegrity structures are extremely lightweight while also being very strong… That’s the reason there’s a heavy amount of interest right now in researching the use of tensegrity structures for outer space exploration. The goal is to find a way to deploy a large object that initially takes up little space.”

From Flat to Fully Unfurled at 149 Degrees Fahrenheit

In order to take up very little space, the struts are temporarily folded flat. This is possible as they are 3D printed as hollow shapes with a narrow opening which runs through the tube. At the end of each strut is an attachment point which connects the cables, also made using 3D printing.

After printing, the flat structures are put into 149 degrees Fahrenheit (or 65 degrees Celsius) water and begin to unfurl. This happens as the struts are 3D printed using shape memory polymers. It’s then the “memory” of the struts which makes this happen and researchers can control the speed.

“We believe that you could build something like an antenna that initially is compressed and takes up little space, but once it’s heated, say just from the heat of the sun, would fully expand,” said Jerry Qi, a professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech. Another idea is using the structures for shape-change soft robots.

The researcher’s work was sponsored by the National Science Foundation and the Air Force Office of Scientific Research. Find out more by reading the research published in the journal Scientific Reports.

Weekend Project: Make Life Easier with the Pocket-Sized Keytool

Weekend Project: Make Life Easier with the Pocket-Sized Keytool
By Tyler Koslow

Looking for an easy way to organize your life? This 3D printable keytool will hold your keys, USB, a small ruler, a docking device for your phone, and even a bottle opener all in one place.  

It’s the little things in life that can make or break your day. What better way to ensure that life goes smoothly than a bit of organization. Today’s Weekend Project is a 3D printable keytool that will give you easy access to a number of gadgets that always seem to disappear when you need them most.

Now, you can keep five essential tools in your pocket with this 3D printed Keytool designed by Lucas de Groot. The project, which was recently shared on Instructables, is an easy and fun way to make something functional with your 3D printer.

In under one hour, you’ll have yourself a one-stop shop for your house keys, a USB drive, a ruler, a mobile docking device, and a bottle opener. This 3D printed Keytool is great for beginners or makers who want a practical example of what desktop 3D printing is capable of.

Interested in undertaking this useful project? Let’s take a quick look at what you need to make your very own Keytool.

3D Printed Keytool: What Do You Need?

The frame of the Keytool is 3D printed, but you’ll also need a few components to put this useful little kit together. Aside your 3D printer, filament, and of course, keys, here’s what else you need:

USB Flash Drive
2x M6 Countersunk Bolts

4x M6 Hex Nuts

3D Printed Keytool: Putting it All Together

The first step to making this Keytool is 3D printing the three separate STL files, which de Groot has made freely available on Instructables. The maker shares that he 3D printed his own with PLA, using a low layer height ranging between 0.2 to 0.1 mm.

Once the 3D printed parts are ready, you’ll insert the M6 Hex Nuts into one side of the Keytool. The model is designed so that they should fit snugly and not fall out.

Then, taking the other part of the Keytool, you’ll plug in the two bolts. Choose one bolt to mount your keys and the USB ring before tightening everything together. On the other bolt, you’ll place two nuts to make sure the parts don’t move around.

Finally, you’ll attach the sides together and screw the 3D printed parts together. de Groot mentions that the bolts should not be screwed too tightly because “the keys have to move smooth but the sub needs to stay in any position you put it”.

And that’s it! Now you have your very own 3D printed Keytool. The designer recently entered this project into Instructables’ Pocket-Sized Challenge. So, if you love this neat little t0ol, feel free to vote for it and check out the other small (yet significantly useful) 3D printing projects!

La Bandita: Hackrod and Siemens Partner to Develop Self-Designing Car

La Bandita: Hackrod and Siemens Partner to Develop Self-Designing Car
By Anne Freier

Hackrod is partnering with Siemens PLM Software to help accelerate the development of La Bandita, a self-designing speedster that will be produced with virtual reality, artificial intelligence, and 3D printing technology.

Self-driving cars are currently being explored and tested, and while recent news has shown a deadly side to the concept, we seem to be nearing a future where artificial intelligence will soon play the role of our chauffeur or taxi driver. However, innovative technologies are not only being used to automate how vehicles navigate the road, but also how they’re designed.

One company is already looking to the future where an automobile will be able to design itself. Hackrod, the start-up behind the idea, aims to create custom-made vehicles by combining 3D printing with virtual reality (VR) and AI. The company plans to build cars that are ‘self-designed’ using generative design-based algorithms.

To make this effort possible, Hackrod has partnered with the German automation giant Siemens to help drive the acceleration of this concept. The Siemens Digital Innovation Platform is teaming up with the startup to develop its first car: La Bandita.

Siemens will provide a range of PLM Software tools, including the NX software and the cloud-based software Solid Edge Portal. This will enable Hackrod to produce a test version of La Bandita more rapidly.

“Hackrod’s vision for automotive design is an exciting and unique use of our design and engineering software. [It] is completely in line with Siemens’ vision for the future of manufacturing. We look forward to seeing the ‘La Bandita’ speedster. it as proof of concept for this revolutionary design to production methodology,” said Bob Haubrock, the Senior Vice President, Product Engineering Software, at Siemens PLM Software.

Furthermore, the partnership will provide huge cost savings for Hackrod, while also expanding Siemens’ growing portfolio of niche project support.

La Bandita – AI, VR, and 3D Printing Take the Wheel

Through the partnership, Hackrod is developing a platform that will enable bespoke design. The automotive production technique will utilize VR as a design tool, IoT and machine learning to constantly improve engineering systems, and industrial 3D printing to produce optimized hardware from structural alloy.

Slade Gardner, CTO at Hackrod, said the partnership with Siemens builds on a shared vision for automobile design and engineering.

“Because the Hackrod vision includes rapid data collection for product design and iteration; and customized manufacturing of sophisticated mechatronic systems, Siemens’ hardware connectivity for Industrial IoT and multi-axis additive manufacturing are critical to success. The products of our partnership will illustrate the impact that an efficient and motivated team can have with access to world class digital design, engineering, visualization, manufacturing and inspection power.”

Hackrod claims that it would be easy for anyone to design their dream car with this technique.

For automotive enthusiasts intrigued by La Bandita, Hackrod is already offering a pre-order option for the car on its website. The company originally ran a crowdfunding campaign for the project with great success – tripling its original funding goals.

Peacock Gets 3D Printed Prosthetic Leg from Random Reddit User

Peacock Gets 3D Printed Prosthetic Leg from Random Reddit User
By Tyler Koslow

A Wyoming family’s pet peacock lost its foot from frostbite, the owners went searching for help on Reddit. One random user decided to design and 3D print a prosthetic device for the majestic bird, giving it a better chance at leading a quality life.  

After braving this year’s chilly Wyoming winter, one family’s pet peacock lost its leg due to harsh frostbite. Although its stump healed quickly, it was unclear whether or not the winged beauty would be able to lead a quality life.

Fearing that the vibrant bird would struggle after losing the limb, the owners went searching for a helping hand on Reddit.

Thanks to the kindness of one random user, the male peafowl was given a new lease on life. Using a prosthetic model previously used to aid a stork, the man had redesigned and 3D printed a leg for the pet peacock. The Wyoming family and Redditor exchanged dimensions through email, and soon after, the 3D printed prosthetic arrived in the mail.

“It’s amazing that people took their time and money  to help us and a peacock that they will more than likely never meet,” the peacock’s owner said to The Daily Mail.

Wyoming Peacock Adjusts to Life with 3D Printed Prosthetic Leg

At first, the peacock struggled to adjust to the 3D printed limb replacement. And so, the family set up an enclosure for the bird to grow accustomed to the prosthetic. They also added felt padding and support brackets for increased comfort.

The 3D printed prosthetic is currently attached to the limb with zip ties, but Velcro straps could be added to make it easier to remove and adjust the device.

The bird was monitored for a few days after the assistive device was fastened, and the owners soon realized that they had to make adjustments. The owners also had to stop the peacock’s wing from dragging on the floor, which it was doing to help balance.

While the pet peacock is still getting used to the 3D printed prosthetic leg, he can be seen happily hopping around on his new foot.

The midwestern couple that owns the bird has a popular YouTube channel called Our Wyoming Life, where they showcase the daily occurrences of ranch life. They recently shared the story of how their peacock received and adjusted to its new prosthetic device.

Weekend Project: 3D Print Your Own Magnetic Stirrer

Weekend Project: 3D Print Your Own Magnetic Stirrer
By Tyler Koslow

Need some on-the-run laboratory equipment or just a neat way to mix liquids? One hobbyist named John Coggeshall shows us how to build a 3D printed magnetic stirrer. Let’s get scientific!

Do you remember your first mind-blowing experience in science class? Was it a chemical reaction oozing out of your beaker? Staring slack-jawed as you learned about the magic behind magnetic fields?

Whether or not scientific experimentation currently plays a integral role in your career, science has most likely shaped your life in one way or another. And, using your 3D printer, you can bring those fond memories of exploration back into your life.

A hobbyist named John Coggeshall has recently created a 3D printed Magnetic Stirrer. He decided to build one after learning that his fiancee wanted a better way to mix her paints.

This scientific instrument works by using a motor to spin two powerful magnets with opposite polarity. These components are mounted under a platform that will hold the beaker. By placing a pill-like contraption containing two additional magnets into the liquid that will be mixed.

The magnetic attraction between the pill and motor-mounted magnets will align. Finally, once the motor is turned on, the magnets start to stir the liquid.

Sounds a bit complicated, doesn’t it? Well, believe it or not, building your own 3D printed Magnetic Stirrer is easier than it looks.

3D Printed Magnetic Stirrer: What Do You Need?

According to Coggeshall, there’s almost no soldering required, and you’ll only need a few electronic components. Aside from a 3D printer and PLA filament, here’s what else you need to start putting a little spin on your weekend:

STL Files (via Thingiverse)
1 x Female 5.5 x 2.1mm M80 power jack

1 x 80mm 12V PC Fan

1 x 12V Motor speed controller with LCD

2 x 10mm neodymium rare earth magnets

2 x 3mm neodymium magnets

3D Printed Magnetic Stirrer: Putting it All Together

Coggeshall explains the assembly process on This Smart House, a DIY website that contains a handful of interesting projects. After sharing the reasoning behind why he developed the Magnetic Stirrer, he broke down why he settled on each part.

The hobbyist realized that using a 80mm 12V DC computer fan would be much more convenient than designing something to spin the magnets on his own. With the fan as the base, he decided to 3D print an enclosure for the magnets and glue it to the fan.

His model is set up with four magnet slots, even though his project only uses two magnets in this particular section. This was done to allow others to use the outer slots for a bigger stir rod, or even use four magnets if you so desire. The creator of the project shares a bit of insight before moving into the step-by-step assembly instructions.

“When building this device it is really important that the distance between the magnetics within the case, and the magnetic pill itself within the container be as close as possible. They are powerful magnets for sure, but for our purposes even a millimeter or two can drastically change how effective the device is at mixing,” Coggeshall says.

Once everything is 3D printed, there are just a few simple steps to putting it all together with glue and light soldering. In a matter of minutes, you will be mixing and mashing liquids using the power of magnets.

If you want to build you own 3D printed Magnetic Stirrer, be sure to check out the full step-by-step instructions on the This Smart House website.
