In a lab on the 11th floor of ¶¶Òőapp Universityâs Belfer Hall, Joshua Rodriguez, an adjunct professor and lab technician, is reshaping how students engage with physics. Blending theory with hands-on practice, his new makerspace course on 3D printing has sparked excitement, challenging students to bridge scientific principles and practical design, all the while cultivating valuable career skills.
Rodriguez, who has degrees in both physics and philosophy from City College of New ¶¶Òőapp, as well as a masterâs degree in the philosophical foundations of physics from Columbia University, is fascinated by the philosophical questions that quantum mechanics poses. But in the lab, his focus shifts to making these abstract ideas tangible. Students work directly with cutting-edge tools and software, gaining experience in additive manufacturingâskills that go beyond textbooks.
The course has two primary goals: imparting a solid foundation in 3D printing fundamentals and guiding students through Autodesk Fusion 360, a popular 3D modeling software. After introducing various printing methods, including Fused Deposition Modeling (FDM) and Stereolithography (SLA), which uses light to cure liquid resin into solid shapes, Rodriguez dives into design basics. The emphasis, however, is on experimentation.
âI want them to see what happens when you have failed experimentsânot just ones that work,â he said. âUnderstanding and fixing issues builds resilience and problem-solving skills essential for any engineering or science field.â
Rodriguezâs approach to teaching extends beyond instruction; heâs invested in giving students the autonomy to create. In the 11th-floor lab, students can access the 3D printers any time during the week, tackling personal and class projects. Materials range from plastic to carbon fiber composites, and the department plans to add a metal printer soon. Itâs a makerâs playground, complete with the promise of a new electronic lathe for precision work.
One student benefiting from Rodriguezâs guidance is Yoel Jacobson, a student in the Katz Schoolâs M.A. in Physics through ¶¶Òőapp Universityâs PathwaysâŻprogram. The Teaneck, N.J., native views this course as a bridge to his career aspirations in engineering.
âThis course fills a desire among students for more applied engineering,â said Jacobson. âWhen Professor Rodriguez floated the idea about it, students were very excited. Weâre all looking for skills that will translate into something in our careers.â
In Rodriguezâs class, students receive detailed introductions on various techniques before they dive into projects. Their work spans simple outline sketches to intricate stress analysis using Fusion 360âs built-in tools.
âWe start with the basics, then analyze where a modelâs weak points might be,â said Jacobson. "For instance, we recently examined how stress affects different lengths of plastic blocks, testing our findings with math, educated guesses and computer simulations."
One of his standout projects has been a honeycomb-inspired ring. For Rosh Hashanah, Jacobson designed it with a honey dipper shapeâa nod to the holidayâs traditions. âProfessor Rodriguez gave us creative freedom, so I came up with something that felt personal and relevant to me,â he said. âAnd we get to print them, which is an incredible opportunity to see our digital ideas brought to life.â
Dr. Fredy Zypman, physics professor and chair, said that seven years ago, the department began shifting toward applied physics and engineering to meet the market demand for these skills.
âAfter building the makerspace and developing the software, we realized we had the infrastructure and interest to launch a 3D printing course,â he said. âStudents were keen on learning practical skills that would help them land and excel in high-tech jobs.â
By guiding students in hands-on experimentation, Rodriguez is equipping them to handle real-world challenges. Itâs about much more than software proficiency or technical know-how. âLearning 3D CAD and programming isnât just the next step,â he said. âItâs about giving students a sense of ownership over their learning.â
In the rapidly advancing field of physics, Rodriguezâs 3D printing course is a testament to ¶¶Òőapp Universityâs commitment to forward-thinking education. By blending tradition with innovation, the department is preparing its students to be the problem solvers, creators and critical thinkers of tomorrowâs workforce.
For Jacobson and many of his classmates, the course has brought physics to life. âStudents always ask, âWhen will I use this in my career?â But you canât say that about this class,â he said. âIt pushes us to think beyond the classroom. Professor Rodriguez has made the subject engaging, combining physics and engineering in a way that feels practical and exciting.â
