Where Sparks Fly: Michigan Tech Builds Metalcasting Momentum with METAL

Dr. Paul Sanders fell in love with metalcasting in the foundry at Michigan Technological University more than 30 years ago. Today, as a materials science and engineering professor at his alma mater, Sanders teaches more metalcasting students at the university than ever before.

Located just miles from Lake Superior in Michigan’s Upper Peninsula, Michigan Tech has built a legacy of preparing the next generations in American manufacturing. What began as a training school for copper mining engineers in the late 19th century has grown into one of the nation’s top institutions for STEM academics and research. With support from METAL, the university is fueling its metallurgical education — sparking curiosity in metalcasting for aspiring engineers and high school students. In only a few years, Michigan Tech’s metalcasting course has grown from 40 to 60 students, but Sanders plans to welcome more.

“We have untapped demand,” Sanders explained. “We’ve tried to figure out how to grow enrollment. How do we offer more students the opportunity to take metalcasting while maintaining the quality of the experience and meeting student needs?”

Through new equipment and staff funding, METAL is helping Michigan Tech meet its hot metalcasting demand.

Stoked for Casting 

Led by IACMI – The Composites Institute®, with funding from the Department of War’s IBAS Program, METAL is accelerating the development of a highly-skilled, adaptive workforce in the U.S. casting and forging industry. By 2033, nearly 4 million manufacturing jobs could be available in the U.S. without sufficient talent to fill them. METAL is working to change that.

Through hands-on K-12 workshops, metallurgical bootcamps and apprenticeships, METAL powers the curiosity, innovation and training that will revitalize American manufacturing.

“We’ve lost a lot of manufacturing to the rest of the world, in part because we didn’t value it and because we didn’t educate people on how to do it,” Sanders said. “By teaching our students to understand manufacturing again, we’ll be able to bring it back to our communities.”

Mahana Gallmeyer, a materials science and engineering major, enrolled in Michigan Tech’s metalcasting course for the chance to make her own cast-iron pan. But, gaining more than a skillet, Gallmeyer left with the knowledge and skills to propel her engineering career forward.

In one semester, Gallmeyer studied scientific theories and terminology while learning every step of the casting process in the foundry. She used CAD software to create and 3D-print molds, compared sand types, melted ingots, and ladled liquid metal in preparation for fiery pours. Along the way, Gallmeyer cast aluminum tokens and custom gray iron bookends etched with the College of Engineering and Science’s flame of knowledge.

“Maybe I didn’t have the best intentions first coming in,” Gallmeyer joked about the pan. “But I’m really glad I took the course. You get ownership of an entire project from start to finish, and no matter where you go in industry, there will be cast materials.”

Plus, she added, the class is just fun. 

At the end of the semester, Sanders invites industry professionals to speak to students about foundry career opportunities. He’s especially eager for younger students to see the breadth of engineering roles across the metal industry, from molding materials to die casting aluminum, as well as investment and continuous iron casting.

“We’ve come to the realization that this is a valuable class to take before you’re a senior,” Sanders said. “We think metalcasting is important to the development of manufacturing engineers, and we want students to learn about it earlier in their careers.”

But safely teaching hands-on casting and forging requires a foundry filled with equipment and a team of trained faculty and staff. Only 20 colleges in the U.S. are certified by the Foundry Educational Foundation to prepare students for a future in metal manufacturing, and Michigan Tech is one of them.  

“Most professors are severely short in technical staff, and they don’t have anyone to take care of the equipment or do industry projects,” Sanders explained. “METAL is not only setting up an infrastructure that helps us teach courses better, but also helps us support American manufacturing better.”

With METAL’s support, Michigan Tech has upgraded its foundry with new equipment, including a tumble blaster to clean and smooth finished castings, a jolt squeezer for compacting green sand, and resin 3D printers. Plus, with added staff resources, Sanders and his colleagues have been able to open the course to more underclassmen and add curriculum to the existing semester-long course.

“We’re hopefully going to see a transition to more U.S. manufacturing,” Sanders said. “METAL is helping us deliver more engineers with the experience we’ll need going forward.”

METAL’s support extends beyond the classroom, providing more staff and supplies for Michigan Tech’s K-12 Summer Youth Programs — where Gallmeyer first saw metalcasting in action.

Soaking Up Foundry Fun

Raised in a family of engineers, Gallmeyer always knew she’d follow the same path. But she wasn’t sure which industry it would lead to. Before graduating from high school, Gallmeyer attended Michigan Tech’s Summer Youth Program and discovered a field she never considered: metallurgy and forging. 

At the time, seeing sparks fly from a molten pour, Gallmeyer couldn’t believe her eyes.   

“It was really cool to watch and then throwing a piece of metal on the fire was wild,” she remembered. “I was like, ‘Are you sure we should be doing this?’ But it was fun to be so hands-on.”

Dr. Alexandra Glover, an assistant professor in materials science and engineering who helps lead the “Metal Casting: Forge Your Future” program, said the best part is igniting students’ enthusiasm and teamwork. Thanks to funding from METAL, this experience is available to more Michigan high school students than ever before.   

“It’s really fun to see the students come together and get excited about science,” Glover said. “I think that’s why a lot of people find these camps and metallurgy careers attractive — it’s hands-on, and making something you designed is pretty rewarding.”

For one week, campers learn how to create lost foam and sand castings, mix liquid nitrogen ice cream and practice casting techniques with chocolate. They also have a rare opportunity to explore Grede Foundry, a local manufacturer that specializes in safety-critical parts for automobiles, industrial machinery and commercial trucks.

“We take the students to see what a career in material science or metallurgy would look like,” Glover explained. Data shows that moments like this matter: About 60% of Gen Z survey respondents said they might have been interested in manufacturing if they’d had access to related programs in high school, yet more than half said they weren’t introduced to manufacturing opportunities before graduation. 

“When we look at how to get more students into the foundry, meeting students where they are and aligning with their interests is the key,” said Glover, who discovered her love for metallurgy in her high school’s jewelry art class. “A lot of casting and forging programs are focused on blacksmithing, and that works for some students, but we try to have avenues for someone who might be interested from a creative arts background, too.”

For Gallmeyer, stepping back into Michigan Tech’s foundry as a college student was a full-circle moment. Instead of watching faculty transform molten metal into new creations, she was the one donned with PPE, ready to cast science, creativity and her future.

“I got to watch casting from behind safety glass in high school,” Gallmeyer said. “It was exciting to actually pour and understand the science behind it this year.”

This spring, Michigan Tech plans to host hands-on bootcamps for career seekers, industry professionals and college students. Ready to ignite your future? Start METAL’s free online training and visit our events page to attend the next METAL bootcamp or workshop near you.

Aiming Higher: U.S. Air Force 2nd Lt. Savana Ohlenburger Finds Her Fit in Munitions Manufacturing

Wife, mother and Airman Savana Ohlenburger has always led a life of service. After years of exploring careers in healthcare, she decided it was time to pursue her lifelong dream — joining the United States Air Force. Today, 2nd Lt. Ohlenburger supports the nation’s defense and munitions manufacturing with training from METAL. 

Ohlenburger, 33, had no metalcasting experience when she applied to the Air Force’s Officer Training School. But growing up with two chiropractor parents sparked her love of science and helping people — interests that followed her like a tailwind throughout her career. After earning a bachelor’s degree in business administration and management, Ohlenburger pursued medical school and later became a massage therapist. However, neither path felt like the right fit.

She’d always dreamed of becoming an Air Force doctor. With encouragement from her husband, Zackary — an Army Reserve welder — she realized it wasn’t too late to aim high and forge a new future for her family, even if it wasn’t through medicine. 

“I was looking for a career,” Ohlenburger said. 

It turned out the Air Force was looking for Ohlenburger’s skills, too. 

“They mostly accept engineers,” she said. Ohlenburger applied to officer school twice before a supplemental board reevaluated her qualifications and accepted her. “A supplemental board was like, ‘Wait a minute, we need more than engineers this time around.’”

More than a year later, Ohlenburger is a project manager in the Air Force’s Attack Munitions Branch. Or, as she likes to joke, a professional “cat herder.” But instead of cats, she’s wrangling some of the nation’s top materials science engineers and metallurgists.

Cat Herding and Metalcasting

Led by IACMI – The Composites Institute®, with funding from the Department of War’s IBAS Program, METAL equips industry professionals, career seekers and students with the metalcasting and forging skills to strengthen American manufacturing. By 2033, nearly 4 million manufacturing jobs could be available in the U.S. without sufficient talent to fill them, directly affecting the nation’s ability to meet defense and supply chain needs.

President Donald Trump’s 2025 National Security Strategy underscores this urgency, emphasizing that America’s industrial base is essential to both peacetime and wartime readiness. “Cultivating American industrial strength must become the highest priority of national economic policy,” the president wrote in the report.

Ohlenburger and her team are key to this mission. In her role, she manages production development across engineers, milling operators and foundries — helping build aircraft and weapons that protect the U.S. in hostile airspace. But without an engineering background, Ohlenburger faced a steep learning curve. Suddenly, she had to decipher metallurgical acronyms, understand materials inside a fighter jet, and track the science behind quality testing.

“I had no clue what the names of different tests meant, so I didn’t know when they failed,” Ohlenburger explained. 

She quickly realized she needed to understand how metal behaves to answer questions like: How is it reacting? Does it meet the right material properties? Will this batch of parts perform in a specific weapons system? Are the components built to spec and meeting safety standards?

“It all comes down to understanding what the subject matter experts are talking about,” she said. “They’re very technical, and I’m supposed to be the big picture person.” 

Only months into her role as project manager, Ohlenburger knew she’d need a stronger foundation in metal manufacturing to pilot her team smoothly. When she learned about METAL’s metallurgy bootcamp, she jumped at the chance. Ohlenburger completed the free, self-paced online training and traveled to Penn State University for a hands-on foundry experience. 

Fueling Excellence in U.S. Defense

For four days, Ohlenburger learned the fundamentals of designing, melting and pouring a metal cast. She transformed solid bronze into a medallion and cast aluminum into her own stein — all while absorbing the terminology her colleagues use every day. Holding ladles filled with molten metal brought manufacturing to life far beyond spreadsheets and reports.

“My favorite activity was when we melted and poured bronze,” she said. “It was really entertaining, partially because liquid metal is so cool, but they let us actually pour it, and feeling the weight difference between aluminum and brass was shocking.”

Penn State Associate Professor Dr. Paul Lynch said his ultimate goal is to spark interest in the metal industry. During the four-day bootcamp, Lynch and his colleagues guide participants through the entire manufacturing process — from designing a 3D mold to sanding a finished casting they can take home.

“When we teach design and modeling, they’re designing exactly what they’ll make in the laboratory,” Lynch explained. “It’s an action packed four days and incredibly hands-on.” METAL also offers advanced bootcamp like Sand Science and Digital Technologies and can host private sessions for government organizations. 

The most valuable part of the experience for Ohlenburger was being mentored by metallurgists and connecting with engineers. She asked questions directly related to her team’s challenges and returned to the office with the knowledge to inspire innovative solutions.    

“I didn’t realize how useful the information was until I got back,” Ohlenburger admitted. “Now when I’m in meetings, I can say, ‘Yes, I remember that.’ I know what things are now.”

Testing Toughness, Building Confidence

After pouring red-hot metal into new creations, Ohlenburger explored quality testing — a core part of her team’s work on world-class weaponry and advanced aircraft. She used hardness machines to press dents into cast metal, pulled steel apart in a tensile test to find its breaking point, and ran a Charpy test to measure how much energy a sample absorbs when struck by a swinging hammer.

“It’s like baking a batch of cookies,” Ohlenburger said about metal production. “You can use the exact same recipe, and it still comes out a little different.” Thorough materials testing before, during and after casting helps maintain the Air Force’s high standard of performance, she added.    

Thanks to METAL, Ohlenburger not only understands which tests every aircraft component undergoes — from the wings to missiles to landing gear — but what those results mean. She can see the full picture, connecting every step of munitions production to ensure each part is ready for mission success.

Winning With Metallurgy 

Ohlenburger says the best part of her job is teaming up with the metallurgists and engineers building the world’s greatest Air Force. But that doesn’t mean every day is smooth flying.

“When you get into super technical fields, the subject matter experts are great, but it’s like asking a calculus teacher to explain addition,” she joked. “Sometimes you get someone who understands the question, and other times you get someone who’s been high level for so long they can’t remember how to explain it.”

 

Now, whether she’s brainstorming the next defense innovation or juggling project timelines and budgets, METAL has given Ohlenburger the confidence to help lead the conversation — not just follow it. That kind of training, Lynch said, is exactly what the nation needs. Empowering defense professionals like Ohlenburger while reigniting American metal manufacturing isn’t just smart — it’s essential to the country’s security and future.

“At the heart of our defense are casting, forging and metal rolling industries. We gave our knowhow and facilities away, and we need to train people and get the knowhow back,” Lynch said. “If we do not bring back manufacturing to this country, we are in serious trouble.”

For Ohlenburger, she’s finally found a career where science, leadership and service go hand-in-hand. As her mentors encourage her to aim even higher — in her metal expertise and in her service to the nation — she’s more than ready for the climb.
