3D printing – UofL News Thu, 16 Apr 2026 19:59:09 +0000 en-US hourly 1 Engineering student creates lighter weight replica of UofL presidential medallion /post/uofltoday/regalia-reproduction/ Mon, 13 May 2024 15:27:52 +0000 /?p=60748 UofL President Kim Schatzel had one problem with her role in UofL’s commencement ceremonies: the medallion necklace traditionally worn by the president is quite heavy.

To find a solution, the president’s staff approached the about 3D printing a less weighty reproduction of the necklace.

Luis Gustavo Rodriguez, a student ambassador for admissions and outreach with the , took on the challenge, creating a visually nearly indistinguishable reproduction of the iconic piece. The 80-hour project involved multiple steps, from modeling to 3D printing, sanding, painting and assembling the necklace.

“I had to use different techniques and approaches to ensure that the project was successful,” Rodriguez said. “All of it had its different challenges. Every part had different skills added into it.”

First, Rodriguez created 3D models of each piece of the necklace: the Minerva medallion, the plates for each of the 12 schools and colleges and the chain links. Using the 3D printers in the STEM+Hub, he printed each piece of the necklace in resin, layer by layer. He then sanded, painted and coated them in polyurethane for durability.

“The real trick was getting the artistic skills down in painting the pieces to recreate the medallion coloring,” Rodriguez said. “I applied primer, leaf gold, shading and airbrush shadowing. It’s been quite a while since I’ve used an airbrush.”

The fleur-de-lis pieces posed particular modeling challenges due to their dimensional detail, so for these, Sophie Wegenast, an intern in the added her expertise.

The assembled reproduction medallion necklace weighs 12 ounces, less than 40% of the two-pound original.

“I found the project to be a great learning experience that heightened my engineering skills. It was a fascinating experience that required a lot of patience and attention to detail,” Rodriguez said.

The highlight for Rodriguez was seeing President Schatzel’s smile when he presented the necklace to her.

“This is an amazing reproduction! I am truly grateful to Luis and the creative, innovative student engineers for their incredible work on this project,” Schatzel said. “It will be worn for years to come.”

Rodriguez received his bachelor’s degree on May 11, with a major in bioengineering. Next, he plans to earn an MBA. After that, he hopes to attend medical school to become a pediatric cardiothoracic surgeon.

UofL students help Ronald McDonald House patient with 3D-printed leg braces /section/science-and-tech/uofl-students-help-ronald-mcdonald-house-patient-with-3d-printed-leg-braces/ Thu, 28 Apr 2022 22:19:21 +0000 /?p=56267 When University of Louisvillestudent Caleb He met patient Harleigh Bond and her family at his job at the reception desk at Ronald McDonald House Charities of Kentuckiana (RMHCK), he recognized where he could be of service – and he found just the right resource to help make it happen.

Six-year old Harleigh was 1.4 pounds when born with cerebral palsy and epilepsy and has faced multiple obstacles, including numerous brain surgeries. Her family, from Carter County, Kentucky, stays at RMHCK when Harleigh has doctor and physical therapist appointments or surgeries.

Harleigh’s grandmother, Jatonda Ousley, mentioned to He that she had outgrown the leg braces she needed to continue making development progress in movement and motor skills. With current supply chain issues, the braces were on a waitlist status and not expected until September, as well as being prohibitively expensive for the family. He said that after meeting the family, he realized “little Harleigh deserved everything in the world.”

He researched if he could custom-fit and use 3D printing to manufacture the braces Harleigh needed, but soon realized it might be beyond his expertise. He turned to engineering friends at Speed School of Engineering, who recommended emailing Ed Tackett, director of Advanced Manufacturing Institute of Science and Technology () for assistance. “He’s been very enthusiastic about this project,” said He. “It could not have been done without his support and guidance.”

Monday, April 25, 2022, was the special “fitting day” for Harleigh and her family who drove three hours to RMHCK for the occasion. The boot-style brace is appropriately adorned with cartoon characters from the movie “Trolls,” Harleigh’s favorite. Ousley, Harleigh’s primary caretaker, was grateful for the thoughtfulness exhibited by the students. “I greatly appreciate UofL and Caleb for doing it, and Peyton for making the braces,” she said. “We love it and can’t thank you enough.”

Tackett then assigned the project to Chemical Engineering Junior Peyton Deaton, who is currently doing his first co-op rotation at AMIST, and asked if he would figure out how to make it work. Deaton relished the challenge, and used a 3D scan of Harleigh’s leg that He sent to work on a prototype, and after trying three different prototypes, Deaton fashioned the shape that worked.

Ousley explained what the braces will allow for Harleigh, who suffered some setbacks after her latest brain surgery.

“These help her get stronger in the legs, and with the right equipment it will help her to start standing up again, and get back to where she was,” said Ousley. “When Harleigh was being fitted for braces before, she had to be sedated. This is going to help tremendously. You’ve really made a difference.”

Having the shareable and inexpensive technology to make these braces could potentially help thousands of kids with similar issues.

Six-year old Harleigh is shown wearing with her 3D printed leg brace.

“For families with really good medical insurance, this might not be an issue, but what do we do to help disadvantaged families?” said AMIST Director Ed Tackett. “We can use this technology to provide positive patient outcomes and train students to do this,” he said.

“This was an opportunity where I saw something, connected with people with great expertise and talent and we got something done, and I’m so proud of that,” added He.

As for Harleigh, she’s just happy to have new “Troll shoes.”

UofL engineering students collaborate on project with Kentucky School for the Blind /section/science-and-tech/uofl-engineering-students-collaborate-on-project-with-kentucky-school-for-the-blind/ Thu, 24 Mar 2022 19:03:32 +0000 /?p=55979 University of Louisville Speed School of Engineering is offering an elective course this semester focused on the design and prototype of educational models to enhance STEM education for blind or visually impaired (VI) students. Currently, 13 Speed School students, including undergraduate, graduate and doctoral students, have participated. Most of the students are majoring in chemical engineering, but some are mechanical or electrical.

Vance Jaeger, assistant professor, chemical engineering, instructs the class, teachingstudents about the development of models using CAD software to iteratively design and produce tactile educational prototypes with 3D printers. Since scientific and mathematical concepts are often taught through visual means like graphs, figures, equations, models and videos, these methods are insufficient for VI or blind students. Jaeger and his students are working toward the goal of creating tools for teaching VI students.

The project was granted $25,000 from NASA Kentucky EPSCOR (Established Program to Stimulate Competitive Research) funding in September 2021, with $25,000 cost share from UofL.

“The pool of money is meant to fund research that gets people kick-started in a new area,” said Jaeger.

The inspiration for the idea came from Jaeger seeing stories online about aids for blind people, while at the same time being interested in getting into 3D printing.

“The two things sort of clicked in my head, and so I contacted the Kentucky School for the Blind,” he said.

There, he met science instructor Adam Stockhausen, who is now advising the UofL students on which concepts are most needed by visually impaired K-12 students and providing feedback on design iterations. Stockhausen is also developing a curriculum guide and tutorial for other VI instructors to ensure that the models see use within classrooms across Kentucky and the United States. UofL students’ digital designs will be shared freely and openly with the maker community and educators through popular digital file sharing platforms as well.

When Jaeger was doing his research for the project, he found a great resource and ally in Mona Minkara, an assistant professor in bioengineering at Northeastern University, who is blind.

“I met her at one of the chemical engineering conferences, and told her I had some ideas about making chemical models for blind students,” Jaeger said. “She’s somebody who’s been very helpful and has resources on her website on how to reach blind students and how to make things more accessible, so she has helped me learn.”

The course crosses multiple disciplines in engineering concepts.

“Mechanical engineering is very big in computer-aided design and we don’t have much of that around here, so I think that’s a need we have in the department,” said Jaeger. “The 3D printing technology is a mixture – you have the computer side, the mechanical, electrical and chemical side, such as materials. What is the right material and material properties to convey these ideas? What plastic? What polymer? What strength of material?”

For KSB instructor Stockhausen, partnering with Jaeger and Speed School students was a great collaboration to find ways to get ideas across to his current student population.

“There were some things that I just had no idea how to approach,” he said. “Describing things with words and then having a picture up on the screen that only half of my class can access is not effective to make sure everyone has a good understanding of what we’re talking about.”

He said he’s used some models in the classroom over the last three years that have helped convey his ideas to his students.

“The ones we’re currently working on aren’t quite ready, but by the end of the UofL students’ projects, I’ll be able to bring them into the classroom and show them to my kids,” he said.

Stockhausen will continue working on the project throughout summer 2022 developing lesson plans based on the models created.

Jaeger said he believes the project will impact at least three communities of people. The main focus are the high school students at KSB and other high school students whose instructors decide to use these models. The second group are the Speed School students, who are learning computer-aided product design as well as incorporating accessibility for persons with disabilities into what they are creating. The third group is teachers.

“With 3D printing becoming more commonplace, we can make it simple enough for any instructor out there to use it,” he said.

Madelyn Peter, a junior in chemical engineering, said she was initially interested in the course when she learned they would be doing 3D modeling, something she enjoys but doesn’t often get the chance to do in chemical engineering. Another reason this course appealed to her was the combination of engineering disciplines.

“We’re mixing mechanical, electrical, all kind of things,” she said. “It’s beneficial because just like on co-op, you’re never just a chemical engineer, you’re all kinds. Having a class here that introduces you to other disciplines and having that experience has been really nice.”

She also believes the class has taught her to broaden her perspective.

“As an engineer, that’s something we should always be considering, making things as accessible as possible,” she said.

“I just think it’s great that we’re moving forward with projects in the undergraduate/graduate program with these kids working on stuff that will broaden their horizons and make them actually realize that not everything is built in the world to allow for everyone to have equal or equitable access to it,” Jaeger added. “We can try and bridge those gaps by actively incorporating that into design as we’re making it, rather than thinking of it as an afterthought.”

Speed School’s 3-D printers put to unexpected uses during coronavirus outbreak /section/science-and-tech/speed-schools-3-d-printers-put-to-unexpected-uses-during-coronavirus-outbreak/ Mon, 06 Apr 2020 17:39:06 +0000 http://www.uoflnews.com/?p=49996 When Lowe Elementary School Technology Coordinator Lyn Travis attended a two-day workshop about 3-D printing earlier this month through the University of Louisville’s Speed School of Engineering, she had no idea she would be employing her new skills so soon – and in such an impactful way.

One week before the JCPS schools shut down due to coronavirus concerns, the teacher had been at AM Watch, a National Science Foundation–supported workshop at UofL’s Additive Manufacturing Institute of Science and Technology (AMIST). There, Travis was learning the latest trends in using 3-D printing for classroom use. As part of the program, 25 teachers were given a 3-D printer for their classrooms.

Now, Travis is filling a small but vital role, along with other teachers, by putting her printer to work, making components for face shields, part of PPE (personal protective equipment) for front line nurses and health professionals.

The coronavirus pandemic has caused the demand for PPE for healthcare workers to skyrocket – a demand supply chains cannot keep up with. UofL engineer and Navy vet Ed Tackett coordinated a response at the AMIST facility at UofL Speed School of Engineering to fill this gap. Speed School student volunteers trained on 3-D printing equipment are volunteering their time, with the AMIST facility production team printing face shields as quickly as possible.

By April 3, Tackett had orders for 27,000 face shields.

Emily Villescas, who has been spearheading the community engagement effort at AMIST, said when they contacted the teachers who attended the recent workshop to help with printing the PPE for local hospitals, the response was immediate.

“Within hours, I was getting emails from teachers all over wanting to help,” said Villescas. “It was pretty amazing. We sent them files on how to print the face shield frames approved by the state and the CDC, and are coordinating with them to deliver the parts to local drop-off sites. It really shows you their dedication to helping people, both in and out of the classroom. We would not have this kind of movement with this project without the teachers, so we are all so grateful for their support.”

With 25-to-30 teachers already on board, and the word spreading every day, Tackett said the efforts are making a significant impact.

“Every shield they make, that means another healthcare worker is protected in state of Kentucky,” said Tackett. “If you do the math, each printer can print two shields every two hours, and with 25 printers, if they run for six hours, that is 300 face shields a day just from JCPS.”

Travis, who teaches computer technology to all 600 K-5thgrade students at Lowe Elementary, said her principal, Mr. Allain, was immediately on board with Travis taking her printer home to help with the effort. So far, Travis has printed 17 headbands (or face shield frames) and delivered them to a community drop-off site.

The teacher said she feels an obligation to continue printing the shields until there is no more need, even if she has to buy supplies herself.

“It feels good knowing those pieces I dropped off last week went directly to help fill an order for UofL Hospital. I feel like I’m doing my part to be part of the solution not the problem,” she said.

For the students Travis teaches, she said there will be a real lesson when they return to the classroom, and beyond.

“It’s because of my school administrator letting me go to the AMIST workshop that we are helping with a local solution to this massive worldwide problem,” she said. “The kids might not realize the impact today, but when they’re old enough they’ll be like, ‘Wow we were a part of that.’”

Fourth–grade teacher Heather Kemp said that after she attended the workshop, she was printing 3-D crayfish with her students at Middletown Elementary. Kemp, who teaches all subjects but focuses on math and science, wanted to incorporate STEM learning. But that can wait, because now it is all about printing face shields.

Kemp said she is heartened to observe that “as the virus is growing exponentially, so is the growth of helping hands to combat it. If you look at two teachers, then 35 teachers into one small community, then the designs for the shields being shared and spread to other states, it’s growing every day.”

When the day comes that students return to the classroom, Kemp said there will many lessons to learn.

“When you think about Muhammad Ali’s maxims about giving back, or the Mayor’s Give Back Day, next year, my kiddos will have a great example of how the community gives back. This coronavirus is affecting some of them personally, who have moms and dads who are doctors and nurses. They will have lived through this and it will make that day even more meaningful,” she said.

Local drop-off sites include:

  • Norton Commons at 9418 Norton Commons Blvd. Prospect, KY 40059
  • CORE Combat Sports at 13124 Eastpoint Park Blvd, Louisville, KY 40223.

Both of these have labelled boxes in the front dedicated to drop offs, which will be picked up on Friday nights. No face-to-face contact.

  • The AMIST Facility on Belknap campus is taking local drop offs at one of the loading docks that will be labelled
  • ALL deliveries can be sent to this address as well: 1940 Arthur Street Louisville, KY 40208.

3-D Printing, tiny tech and Iron Man at UofL conference /section/science-and-tech/3-d-printing-tiny-tech-and-iron-man-at-uofl-conference/ /section/science-and-tech/3-d-printing-tiny-tech-and-iron-man-at-uofl-conference/#respond Mon, 06 Aug 2018 15:28:37 +0000 http://uoflnews.com/?p=43286 Nanotechnology and 3-D printing can be used for all kinds of things — to quickly and cheaply create prototypes, for example, or to make machines smarter.

And, if you’re Jason Lopes, you can use them to create a working “Iron Man”suit for actor, Robert Downey Jr., or a life-size replica of soccer superstar, Cristiano Ronaldo.

“It’s called pushing the boundaries,” said Lopes, who worked in film special effects before joining technology company, . “When people tell you no, use that as inspiration to show them how it can be done.”

And to push those boundaries, universities and industry can accomplish more by working together. That was the subject of the 2018, held Aug. 1-2 at the Speed Art Museum on UofL’s Belknap campus. Lopes was the first keynote speaker.

The inaugural conference, themed “Strengthening Industry Collaborations with Academia,” focused on collaboration in advanced manufacturing fields, including additive manufacturing and micro/nanotechnology.

“Universities play a critical role in the advancement and application of these technologies for industry,” said Dr. Kevin Walsh, associate dean of research at UofL’s J.B. Speed School of Engineering, who led the organizing committee. “Our goal was to bring both sides together, and showcase the innovation generated by that collaboration.”

The event was apartnership between UofL and the University of Kentucky. Together, they offer a collection of advanced manufacturing core facilities open to industry and academia, called the Kentucky Multi-Scale Network.

Kentucky Multi-Scale is part of the National Science Foundation’s National Nanotechnology Network, which consists of 16 academic sites across the U.S. with similar advanced core facilities.

At UofL, those facilities include the Micro-Nanotechnology Center (MNTC), the Rapid Prototyping Center (RPC), and the Conn Center for Renewable Research. Those facilities work with industry on a variety of projects, from tosaving energy when manufacturing cement.

This goes to show that the potential applications for nanotechnology and 3-D printing are broad, and can impact diverse industries — from space travel, to manufacturing, to medicine, to movies.

Lopes, for example, has also used 3-D printing to create a giant sneezing monster for Comic-Con and light-up mohawks for Katy Perry. Now, he’s working with the dental division at Carbon to make better dentures and embedding tracing technology into .

“This is what excites me,” Lopes said. “Embedding the technology inside all of this.”

And Walsh said combining these technologies, as in Lopes sneakers, could lead to more innovation. For example, he said, future human prosthetics and implants could be both 3-D printed, and contain sensors so they’re smarter, safer and function more effectively.

“But for that to happen, we need the micro/nano community to be fully engaged with the additive manufacturing community,” he said. “This symposium provides that opportunity and we plan to offer it every year.”

Promise Zone: UofL camp inspires students from high-poverty areas /section/science-and-tech/promise-zone-uofl-camp-inspires-students-from-high-poverty-areas/ /section/science-and-tech/promise-zone-uofl-camp-inspires-students-from-high-poverty-areas/#respond Mon, 16 Jul 2018 19:12:50 +0000 http://uoflnews.com/?p=42830 Their journey from southeastern Kentucky to UofL started with a promise — a promise that they would get the chance to do and see things they had never before experienced. It came true in a big way.

Eighteen-year-old incoming freshmen Ryan Shackleford and Katherine Grace Whitaker live close to the Daniel Boone National Forest, some 150 miles away from the University of Louisville’s Belknap Campus. Both will begin studies at UofL this fall, academic journeys inspired by a new type of high school summer camp at the .

Ryan, a graduate of Corbin High School, and Katherine, who graduated from Whitley County High School, live in a high poverty area the federal government has declared a “Promise Zone.” The program is aimed at improving the overall quality of life and, in Kentucky, the targeted area covers 3,071 square miles in Bell, Harlan, Letcher, Perry, Leslie, Clay and Knox counties and part of Whitley County. There are a total of 22 Promise Zone communities nationwide in a mix that includes urban, rural and tribal areas.

This summer marked the third year of the camp, which is designed to broaden interest in science, technology, engineering and math (STEM) careers.

focused on renewable energy with lessons and labs from researchers at the Conn Center for Renewable Energy Research at Speed. This year, from July 9-13, a group of 23 Promise Zone students learned about 3D printing by designing and manufacturing small products at Speed’s Rapid Prototyping Center. They presented their products in a “Shark Tank”-like competition held on the final day of camp.

“It blew my mind what a 3D printer can do,” said Taylor Hall, 16, a Letcher County Central High School junior, whose team worked on a laser surgical cutting device that would replace the scalpel. “We had the best time ever. … I would love to come here.”

Taylor and his teammate, 15-year-old Logan Thornton of Somerset High School, said they also enjoyed the extracurricular visits to Shakespeare in the Park and Louisville Mega Cavern, along with living in a college dormitory for a week.

Ryan and Katherine were among the first group of Kentucky Promise Zone students who attended, also making visits to Louisville attractions while learning what UofL could offer them.

“Before attending the camp, I had not really put too much thought into where I would attend college, but the University of Louisville certainly wasn’t at the top of my list,” said Katherine, who was awarded a Grawemeyer Scholarship and a Vogt Scholarship and is considering majoring in psychology, biology or neuroscience. “I didn’t realize all the resources that were available at UofL, as there are very few people from my hometown who choose to attend there. After the camp, I became aware how much really was happening in Louisville, both at the university and in the surrounding city.”

Ryan, who secured a spot in the Guaranteed Entrance to Medical School (GEMS) program, plans to major in chemical engineering. He is also in the Honors Program and won a Grawemeyer Scholarship. He said the camp gave him his first real experience “working with physics,” and his favorite subjects were solar power and ion lithium batteries, as well as learning how an electron microscope works.

“For the most part, the camp gave me a more in-depth look and hands-on experience with subjects I only knew a little about,” Ryan said. “I had never been on the campus before until this camp. This camp opened up UofL as an option for me. I was surprised by how much I liked both the campus and the city of Louisville. UofL was not intimidating, but friendly and welcoming.”

Both Ryan and Katherine expressed their gratitude to the camp organizers.

“There are many students in this part of the state that are very intelligent and have a lot of potential, but do not get the opportunities that students from larger areas may receive,” Ryan said. “This camp gave students the opportunity to visit a large university outside of our local area.”

Katherine agreed.

“I think this camp is helping to provide unique and meaningful experiences for students in southeastern Kentucky that they otherwise may not be able to have,” she said.

The team came up with the “Spinny Cup,” a device designed to keep coffee and soft-drink cups from spilling in automobiles. The other teams developed a laser surgical cutting device, augmented reality glasses and a hands-free toilet flusher. “I bought all the domain names for all these products,” joked Tackett, director of Additive Manufacturing at the Speed School’s Rapid Prototyping Center, who led the camp.

UofL students tackle bust of Lee Corso for ESPN GameDay /section/science-and-tech/uofl-students-tackle-bust-of-lee-corso-for-espn-gameday/ /section/science-and-tech/uofl-students-tackle-bust-of-lee-corso-for-espn-gameday/#respond Wed, 20 Sep 2017 23:15:27 +0000 http://uoflnews.com/?p=38402 The Cardinal Football team wasn’t the only point of interest during last weekend’s ESPN GameDay appearance on campus.UofL’s Rapid Prototyping Center was contacted by the director of ESPN GameDay the day before the football game against Clemson andwas tasked with printing a 3D bust of GameDay host Lee Corso for a segment highlighting UofL’stechnology and student talent.
RPC manager Tim Gornet assigned students Kate Schneidau and Samuel Williams the opportunity to work with Corso, an experience they were eager to tackle.
A GameDay tradition, Corso wears the mascot head of his pick the central motivation of the challenge. Schneidau and Williams set out to construct a bust of Corso himself that could in turn wear a smaller version of the mascot head. They were initially prompted to work with metal as an additive.
Unfortunately they didn’t realize that metal prints, which can quickly (compared to traditional manufacturing) make extremely complex objects, actually take a long time to make and design and post process. So we quickly had to come up with something to print, and we had to switch to plastics because that was the only method that could be done in under 24 hours from start to finish,” Williams said.
Initially the plan was to superimpose a cardinal crest on his head, but that addition was scrapped because it looked too much like a shark fin, he said.
Schneidau and Williams were at a disadvantage with time, but excited for the challenge.
“This was the first time, for me, to use the scanning and modeling software. Before the bust could be built in out 3D printers we had to scan Mr. Corso’s head. After scanning Mr. Corso, we imported the scan into our modeling software and cleaned up any problems that occurred during scanning. This is where Samuel took over, as I mostly worked on the scanning,” Schneidau said.
Using a sculpting program called MeshMixer, Williams believes the scan was met with complication.
“Living things are much more difficult to capture because even small movements degrade the scan,” he said. “We only had time for one scan, so we didn’t notice until we had already left that most of Corso’s lips and eyes and nose were missing, so we had to add those later by hand with photos for reference. There is never really a perfect scan, so it requires a bit of time to smooth over rough edges and fill in holes.”
After that, he adds, it was as simple as figuring out what size they could print with the time left ontheir plastics machines.They ended up with about six different busts that finished on time.
Corso or Bust
Coordinating with Corso and ESPN GameDay allowed the students to meet Corso for about 10 minutes during the scan.
Both my parents are alumni, so I knew who Lee Corso was. As I was the one scanning I was trying to contain my excitement so that I did not mess up the scanner’s work, afterwards my supervisor told me jokingly that he was watching to see if my hands started shaking. The process was very straightforward; we had Mr. Corso sit in a chair in the middle of the room and I, holding the scanner, walked around him” Schneidau said.
Though theportion of the process that involved Corso was brief, the print itself took a little more time, which meant that neither Scheidau or Williams were available to deliver the final product.
“We weren’t able to give the busts personally, but we dropped them off Saturday morning so that(Corso) could pick out his favorite color,” Williams said. “We didn’t get any of the duplicates back, so I can only assume he liked all of them.”
