3D Printing in STEM Education: How it is Applied
In STEM classes, it can be challenging to keep students fully engaged. Physics, engineering, and math are all complex subjects that can be challenging to understand and apply. Many students lose interest because they cannot see how the lessons apply to their lives.
3D printing makes it fun, easy, and clear to learn. It helps them plan, build, test, and refine their plans. They can learn how to apply STEM principles in their daily lives and turn ideas into practical models. We'll discuss how 3D printing is transforming STEM education and why it's more crucial than ever in this article.
What Role Does 3D Printing Play in STEM?
By adding layers of materials based on digital models, 3D printing, also known as additive manufacturing, makes three-dimensional things. That is a great way to bring hard ideas to life in STEM teaching. Students can plan, build, and test their own inventions, which helps them better understand science and mathematical concepts. Exploration and creativity are essential components of STEM learning, and this hands-on approach encourages them.
1. Visualization Can Help You Learn More
One big benefit of using 3D printing in the classroom is that it can help students see things more clearly. Students can create models of molecules, geometric shapes, or historical items that they can then touch, examine, and interact with in real life. This tactile experience helps you understand complex ideas and structures, making learning easier and more memorable.
2. Fostering Creativity and Problem-Solving
Including 3D printing in STEM classes helps students be more creative and learn how to solve problems. Students need to think critically as they plan and work on their projects. They learn how to identify and fix problems, make adjustments to their ideas, and understand that engineering and design processes are iterative. This kind of hands-on learning builds grit and adaptability, preparing students for the problems they will face in the real world.
3. Building Custom Lab Equipment
Many schools lack the funds to invest in sophisticated laboratory equipment. Students and teachers can make their own tools with 3D printing. This can be test tube stands, beakers, clamps, or even microscope parts. Teachers can print what they need in the classroom instead of having to wait for money or an order from catalogs. It teaches kids how to think outside the box and find creative solutions to problems.
For example, the Custom Lab Institute utilizes stereolithography (SLA) 3D printing to create various laboratory tools, including magnetic racks, powder dispensers, and bead dispensers.
4. Making Prototypes for Engineering
Many engineering schools utilize 3D printing. CAD software allows students to design parts or machines and then print them out for testing. They can check out their plans in the real world. This helps significantly with projects related to robotics, mechanical engineering, and product development. It helps them learn about tolerances, fit, power, and function —all important concepts in engineering.
5. Putting Physics and Math Ideas Into Practice
It can be challenging to grasp abstract concepts in science and mathematics. With 3D printing, these concepts become real things. For instance, kids can print gears to learn about motion and force. To learn about math, they can print out graphs, parabolas, and 3D functions. This helps make tough subjects easier to discuss and less intimidating. You can also talk to other people in the lessons.
The Weber School utilizes 3D printing in various areas, including science and mathematics. The school has helped more than 200 students create over 2,400 3D prints each year by utilizing 3DPrinterOS to manage their printer fleet. This hands-on method enables students to apply scientific theories and mathematical calculations to create and build physical models, thereby enhancing their understanding and interest.
6. Making Devices That Help People
As a way to do service-learning projects, some schools use 3D printers. Students can make gadgets that help people in need and print them out. Custom limbs, grip aids, and tools for children with disabilities are examples. This teaches students how to collaborate with others, think like designers, and consider the impact of STEM on the world. It also ties together tech and helping people.
e-NABLE is a global, open-source group of volunteers whose goal is to create 3D-printed prosthetic hands and arms for people in need that are either free or very affordable. Since its inception in 2013, e-NABLE has attracted thousands of volunteers worldwide to develop, print, assemble, and distribute prosthetic devices. This has significantly reduced the cost of these devices and made them more accessible to people.
7. Making Replicas of Historical Artifacts
3D printing enables students to create replicas of historical tools or artifacts in lessons that combine STEM and history. They can examine copies of fossils, bones, or artifacts that people used to make. In this, history, culture, and science come together. STEM is linked to other areas and shows how technologies change over time.
8. Making Molecular Models Printable
Students can print DNA strands, protein structures, or atomic models in chemistry and biology class. This is especially helpful for observing molecular patterns that are invisible to the naked eye. Students don't look at pictures of molecules in textbooks; instead, they touch them in their hands. It helps them understand more about complicated science topics.
9. Representing Manufacturing in the Real World
Students learn about how current manufacturing works through 3D printing. They learn about testing products, making changes, and fast prototyping. They also see how drawings made on a computer are made into real things. This provides them with a better understanding of the entire process, from planning to production. It's ideal for individuals seeking a career in manufacturing or industrial design.
10. Helping With Science Fair Projects
Students can create more effective science fair projects with 3D printers. Students don't have to use cardboard displays and hand-drawn diagrams when they can print models, tools, or even whole projects. This makes them feel better about themselves and enhances their work performance. It also makes people more interested in working on their projects.
Frequently Asked Questions
How is 3D printing being integrated into STEM education?
It works well to include 3D printing in K–12 schools and university makerspaces. A lot depends on the school's culture and how open the teachers are to trying new things.
3D printing can help students better understand concepts, whether they are learning about anatomical models in health class or landform formations in geology class. They might use it to make pulleys, levers, or binoculars. Often, we hear that robotics classes utilize 3D printing.
