MakerBot Stories | A New Frontier in Tracheal Repair

trachea-feinstein-institute-scaffolding-cartilage

Your trachea, or windpipe, connects the throat and lungs. Air comes in through the windpipe; carbon dioxide goes out.

If it is torn or diseased, surgeons have two ways to fix it. They can remove the damaged part and attach the healthy ends, but there’s only so much slack. Or they can extract some rib cartilage and graft it into the windpipe, which is also made of cartilage. Additional surgery has risks, however. So some patients can’t be helped.

But what if doctors could grow you a new piece of windpipe, just the size and shape you need, from your own cartilage cells?

For the past year, the Feinstein Institute for Medical Research, in Manhasset, NY, has been exploring this question in collaboration with MakerBot.

The team of surgeons and scientists at the Feinstein Institute, the research branch of the North Shore-LIJ Health System, has grown cartilage on a scaffolding made from ordinary MakerBot PLA Filament. Their remarkable results, early investigations that might lead to a clinical breakthrough, are being presented today at the annual meeting of the Society of Thoracic Surgeons, in San Diego, CA.

Tissue Engineering + 3D Printing = New Possibilities

The Feinstein Institute’s findings build on innovations in two emerging fields: 3D printing and tissue engineering. Tissue engineering is like other kinds of engineering, except, instead of using steel or computer code to make things, living cells — skin, muscle, cartilage — are the raw material.

Researchers already know how to make cartilage from a mixture of cells called chondrocytes, nutrients to feed them, and collagen, which holds it all together. Shaping that cartilage into a nose or a windpipe is more challenging.

That’s where 3D printing comes in. The hope is to use a 3D printer to construct a scaffolding and cover it in a mixture of chondrocytes and collagen, which grows into cartilage. There are 3D printers that can extrude living cells, but options are few and expensive; one bioprinter cost $180,000 —beyond the Feinstein Institute’s budget.

So, at the end of 2013, Todd Goldstein, an investigator at the Feinstein Institute, called MakerBot. After several conversations, MakerBot agreed to provide the Feinstein Institute with two MakerBot Replicator 3D Printers, MakerBot PLA Filament, and expert advice in 3D modeling, 3D printing, and materials.

Real-Time Prototyping with Surgeons

Creating a replacement windpipe is uncharted medical territory. It has to be rigid enough to withstand coughs and sneezes, yet flexible enough to allow the neck to move freely.

To develop the scaffolding, Goldstein teamed up with two North Shore-LIJ surgeons who specialize in repairing windpipes. Goldstein would make prototypes of the scaffolding, then bring the prototypes to the surgeons to examine them. Goldstein would adjust his designs based on their feedback, and return in a day or two with an improved design.

Working this way, the Feinstein Institute team was able to develop a strong, flexible scaffolding design in less than a month. Goldstein, who had never used a 3D printer before his call to MakerBot, tested about 100 versions of the scaffolding. When he hit a design snag, he consulted with a designer at MakerBot, who analyzed the 3D files and suggested ways to optimize them for 3D printing.

“The ability to prototype, examine, touch, feel, and then redesign within minutes, within hours, allows for the creation of this type of technology,” says Dr. Lee Smith, a pediatric otolaryngologist at North Shore-LIJ who worked with Goldstein. “If we had to send out these designs to a commercial printer far away and get the designs back one and three and seven weeks later, we’d never be where we are today.”

“Without the 3D printers to do this, the amount of capital we would need would be exponential,” says Goldstein.

Experimenting with the MakerBot Replicator 2X

The next challenge the Feinstein Institute team faced was how to grow the cells on the scaffolding. To test the idea, Goldstein used a handheld syringe to apply the mixture of chondrocytes and collagen to the scaffolding. It was, he said, “like putting icing on a cake.”

After further consultation, MakerBot provided the Feinstein Institute with a MakerBot Replicator 2X Experimental 3D Printer, which has two extruders. Goldstein converted it into a low-cost bioprinter by replacing one extruder with a syringe that dispenses the chondrocyte-collagen “bio-ink.”

replicator-2x-modified-syringe-extruder-bioprinter

To mount the syringe on the MakerBot Replicator 2X, Goldstein modified a universal paste extruder that he found on Thingiverse. The paste extruder, which Thingiverse user nicksears remixed from other extruder parts, is in fact designed to put icing on a cake.

Goldstein modified the other extruder to print in PLA filament instead of ABS. “The advantage of PLA is that it’s used in all kinds of surgical implant devices,” says Dr. Smith, the pediatric surgeon. Goldstein found that the heat from the extruder head sterilizes the PLA as it prints, so he was able to use ordinary MakerBot PLA Filament.

The bio-ink, which stays at room temperature, fills the gaps in the PLA scaffolding, and then cures into a gel on the heated build plate of the MakerBot Replicator 2X. A two-inch-long section of windpipe (imagine a hollowed-out Tootsie Roll) takes less than two hours to print.

Once the bio-ink adheres to the scaffolding, it goes into a bioreactor, which will keep the cells warm and growing evenly. A new bioreactor costs between $50,000 and $150,000, so Goldstein found a broken incubator. With the help of an undergraduate intern, he is converting it into a bioreactor, with gears fabricated on a MakerBot Replicator 2 Desktop 3D Printer.

Proof of Concept

At the conference, Goldstein and Dr. David Zeltsman, the chief of thoracic surgery at Long Island Jewish Medical Center, are presenting the Feinstein Institute’s results from its investigations into how 3D printed windpipe segments held up for four weeks in an incubator. According to their abstract, “The cells survived the printing process, were able to continue dividing, and produce the extracellular matrix expected of tracheal chondrocytes.” In other words, they were growing like windpipe cartilage.

The Feinstein Institute is describing this work as a “proof of concept,” and the team still has plenty of work to do before establishing a new protocol for repairing or replacing damaged windpipes. Medical research can take years to move from bench to bedside, as can Food and Drug Administration approval.

Dr. Smith, the pediatric surgeon, says that he expects in the next five years to harvest a patient’s cells, grow them on a scaffolding, and repair a windpipe. At least one tracheal patient comes through the North Shore-LIJ Health System each year who can’t be helped by the two established methods. In such cases, the FDA has a compassionate therapy exception that allows you to try a promising experimental method like a 3D printed windpipe.

New Careers and The Future of Medicine

The windpipe experiment has already made a profound impact on the research team.

“It’s completely changed the trajectory of my academic career,” says Goldstein, who came to the Feinstein Institute as a molecular biologist, working with cells, chemicals, and drugs. Combining this knowledge with 3D printing and getting into tissue engineering — “I didn’t expect that at all when I got here.”

Now he is the Feinstein Institute’s lead researcher for 3D bioprinting, making models for pre-operative planning and tools to improve the lab. He is also the presenting author of a paper being delivered to thousands of surgeons, and is applying for major grants to continue his research. “Knowing that I could potentially have designed something that will end up saving someone’s child is the most exciting thing I could ever ask for,” Goldstein says.

“This project will probably define my scientific career,” says Dr. Smith. “As we produce something that can replace a segment of trachea, we’ll constantly be modifying and optimizing, the correct bio materials, the correct way to bond the cells to the scaffold.”

“3D printing and tissue engineering have the potential to replace lots of different parts of the human body,” he says. “The potential for creating replacement parts is almost limitless.”

So what’s next? MakerBot has supplied the Feinstein Institute with early samples of forthcoming MakerBot PLA Composite Filaments in Limestone and Iron, so the team can start investigating other applications of 3D printing and tissue engineering.

“Do you remember The Six Million Dollar Man?,” asks Daniel Grande, director of orthopedic research at the Feinstein Institute and Goldstein’s mentor. “The Bionic Man is not the future, it’s the present. We have that ability to do that now. It’s really exciting.”

MakerBot Stories | Mastering the Mini

IMPORTANT UPDATE: We’ve seen significant improvements to print quality and reliability with MakerBot Desktop 3.4 and MakerBot Firmware 1.5. If you haven’t already, please download the latest version of MakerBot Desktop and then use it to update your MakerBot Firmware. NOTE: When printing files via the USB port, your printer’s internal storage, or your Library, reprepare (reslice) them through MakerBot Desktop to achieve the best results. Files that are not reprepared (resliced) will not achieve best results.

Felix Olivieri has worked in a few different art-supply stores over the years. So when he and his wife, Sarah, decided to open Olivieri’s Arts, Crafts, & Coffee in Kingston, a Hudson River town a couple of hours north of New York City, he knew what he wanted: hard-to-find specialty paints and pencils, a coffee bar with a kids’ art table nearby, display cases made from repurposed furniture, and a MakerBot Replicator Mini Compact 3D Printer, which belongs to “the world of art of the future.”

Olivieri had used 3D modeling software, but he’d never made anything on a 3D printer before ordering one for the new store. “Once I got it in, first thing I did was set it up, sit there with a cup of coffee, and watch it print,” he says. “And every day since, people do the exact same thing: They walk in, say, ‘I’ve never seen one of these up close,’ and spend the next 20 minutes sipping coffee, watching it print — and then buy another cup of coffee.”

The Olivieris found some fixtures for the store — hooks, clips, small shelves — on Thingiverse, and made them on the MakerBot Replicator Mini. Felix made nametags for Sarah and other employees using MakerBot PrintShop. The app, which makes custom signs and objects, has been an effective way of explaining 3D printing to his customers.

The Learning Curve

Olivieri has gone through a learning curve with the MakerBot Replicator Mini, learning design tricks and discovering new features, and he has hit some frustrations along the way. “If you unload the filament too soon, that’s when you’re most likely have a misprint,” he says. He has learned to be patient, and wait for the MakerBot Replicator Smart Extruder to cool down first. “Five or ten minutes is not going to slow down your day,” he says.

Caring for The Extruder

“Anything like that is going to get clogged up if you don’t take care of it,” Olivieri says of the extruder. When the Olivieris bought a 3D printer, they also got the MakerBot MakerCare Protection Plan, and he has worked with MakerBot’s support team to troubleshoot and, when it was necessary, to replace his Smart Extruder. Olivieri suggests having a spare Smart Extruder on hand in case you run into issues, so you can keep on printing. Expect challenges, Olivieri says, “but don’t let it get you down when it happens. The worst thing you can do is give up.”

Olivieri’s excitement about 3D printing is contagious. “I want to inspire people. I want to educate people,” he says. “It takes people a little bit to grasp what they want to print themselves.” As he demonstrates the MakerBot Replicator Mini for a curious group of schoolchildren, you can see their eyes being opened to a not-too-distant future when “everything is convenient, everything is at your fingertips. Hit print, there you go.”

MakerBot Stories | Wheels for a Middle School Drag Race

A long hallway at A. MacArthur Barr Middle School, in Nanuet, NY, doubles as a dragstrip for carbon-dioxide-powered model cars. Like the Cub Scouts’ Pinewood Derby, CO2 racing is a fun way for young people to discover design and engineering principles. At Barr Middle School, the dragster race has become a rite of passage.

“They look forward to eighth grade,” said technology teacher and racing commissioner Vinny Garrison. “It’s a project that kids remember.” A showcase outside the old woodshop has a selection of wooden cars and 3D printed wheels, as well as a leaderboard showing the fastest 65-foot runs of the school year — and of all time.

Over the course of seven weeks, each eighth grader will shape a footlong wood block into a car. Each car has a compartment in the back big enough to hold a CO2 cartridge usually used for whipping cream or carbonating water, and beyond that anything goes. The competitive students go for long and lean, while others will shape theirs like a flower or their favorite animated character.

The wheels also take many different forms. Other schools with the CO2 dragster in the curriculum order stock wheels in bulk, but each Barr Middle School racer designs a set of wheels in 3D design software and prints them on a MakerBot Replicator Desktop 3D Printer. Whether form or function is a priority, the 3D printer helps. Those eager to challenge the all-time record — which has dropped from 0.701 to 0.643 seconds in the MakerBot era — craft wheels weighing as little as eight-tenths of a gram. (Stock wheels can weigh as much as five grams each.) Other students create elaborate patterns worthy of a custom-rim shop.

Barr Middle School’s approach to the CO2 dragster project appeals to a wide range of students, whether their interests are engineering or design, competition or craft. It is also a deft integration of older and newer technologies: Students use laptops on shop tables with vises, and the MakerBot Replicator takes its place among the band saw, the rasp, and sandpaper. In the fall, Garrison’s class will be working with a MakerBot Replicator Mini as well.

“I have kids engineering parts—parts that don’t exist,” Garrison says. “They are going to get to college and the teacher is going to be, ‘Oh, you’re good. You know how to do this.’”

MakerBot Stories | University Gets First Innovation Center

Posted by on Wednesday, June 25, 2014 in Uncategorized

The State University of New York at New Paltz is home to the world’s first MakerBot Innovation Center: a ground-floor room with 30 MakerBot Replicator 3D Printers. “3D printing is training students to think in a different way,” says Dan Freedman, dean of science and engineering at New Paltz. “If students come out of here knowing about 3D printing and different applications of it, it will give them a better chance of starting a career.”

The Innovation Center, which has a combination of MakerBot Replicator 2 Desktop 3D Printers and MakerBot Replicator 2X Experimental 3D Printers, is located in the Smiley Arts Building, and sculptors and jewelry designers have been flocking there since it opened in February. Engineers and scientists, whose sit across the quad, are also heavy users of the facility.

It’s not only college students at the center. Faculty from many disciplines and other New Paltz staff have attended sessions with MakerBot trainers. Local artists and manufacturers, as well as others who want to learn about 3D printing without pursuing a degree, can enroll in a two-semester program in digital design and fabrication. And New Paltz has plans to bring in students from local public schools. For bringing the community together, says Freedman, “the only thing similar is the gym.”

Interested in a MakerBot Innovation Center? Let us know.

The MakerBot Innovation Center at New Paltz is part of The Hudson Valley Advanced Manufacturing Center, a $1.5 million initiative to spur regional economic development. The advanced manufacturing center received $250,000 donations from a local venture-capital fund and a matching grant from the regional utility company. “It was the easiest donation this college has ever gotten,” says Freedman, “We were in the right place at the right time.”

“This is a technology that is just starting, and it’s going to become increasingly important,” says Freedman, who thinks that the university’s investment in 3D printing will make New Paltz the right place for budding artists and the engineers of tomorrow.

Katherine Wilson, a student in New Paltz’s renowned Metal program, says, “When I was looking for graduate schools, I was interested in what kind of technology was available.” Before opening the Innovation Center, New Paltz had a few MakerBot Replicator 3D Printers, and she was careful not to monopolize them. Access to an array of 30 3D printers has freed up Wilson to follow her imagination wherever it takes her.

Freedman adds, “I think we can attract some really outstanding students who are undecided between science-engineering and art and say to them, ‘You can pursue your interests in both areas, and we’re going to make it easier for you to do that.’”
