The Value of 3D Printing in STEM Education

It's important to understand exactly what 3D printing is and how it fits into STEM education. It's a method of additive printing that creates a 3D item generated from a computer-created design. It works by adding layers of material one at a time until the object is complete. In contrast, many manufacturing processes are subtractive, meaning that the final object is cut from a larger piece of material. Like other additive manufacturing methods, 3D printing results in less waste. This process is reshaping almost every industry. Right now, 3D modeling is used mostly for making prototypes. However, it promises to make manufacturing by demand and to various specifications a reality for businesses and consumers. This technology can also be very useful in the classroom.


Create a Hands-On Learning Environment

Experiential or hands-on learning results in students who are more engaged with the material and have better learning outcomes. STEM teachers can use 3D printing to foster an active learning environment that encourages students to use their critical thinking skills while learning practical skills. Some secondary schools now use 3D printing in almost all engineering classes. However, teachers across disciplines and age levels can incorporate 3D printing into their lesson plans.


Empower Creativity and Innovation

Creativity skills are often overlooked in discussions about crafting STEM programs to help students achieve long-term success. Intellectual growth occurs when students are forced to use creativity to confront problems. Using 3D printing naturally combines creativity with critical thinking and hard STEM skills as students create a design and successfully execute it. Some schools offer art-based 3D printing classes to students as early as middle school to help them develop their ability to create and innovate.


Facilitate Real-World Understanding

Schools can use 3D printing to facilitate real-life learning experiences in the classroom. For example, students studying anatomy can create their own skeletons. Some dental students have used 3D printers to model teeth and practice procedures. Students aren't the only ones who benefit from this ability: Professional surgeons use 3D models today to practice procedures.


Prepare for Post-Graduate Plans

One of the responsibilities of educators is preparing students to find meaningful work in adulthood. Being able to complete 3D printing projects can be a valuable skill in the workplace. Engineering, manufacturing, health care, design, and entertainment are just some fields where 3D design skills are highly valued. The process of 3D printing involves a variety of valuable skills, including critical thinking, analytical skills, and the ability to create virtual models.


Bolster Digital Engagement

Today's students live in a digital world, and there is every indication that this will be increasingly true over time. Some educators and parents push back on teaching digital skills in the classroom, but it's important to be aware that digital literacy is just as valuable of skill as other types of literacy. Education should help prepare students for the world they live in, not the one that used to exist. Students who learn about 3D modeling can better understand how workflows behind the scenes influence their digital experiences. Also, many students will end up in careers with digital workflows, and learning how to manage them now is setting them up for future success.


Improve Problem-Solving Skills

Learning about 3D printing can help students devise methods for how to solve problems in the real world. When starting a project, students should be able to determine what the finished item will be used for, decide what design features and raw materials will work best, and think about how to make the 3D printing process efficient. Working through the prototype stage of a project teaches kids how to identify and solve potential problems.


Leverage Design Thinking

Design thinking and design skills are important. One important part of design thinking is identifying alternative approaches to problems and finding new solutions. It also requires collaboration with a variety of stakeholders. Additionally, it teaches students the importance of working through a process. For example, a prototype presented to a group might be met with criticism and suggestions the student needs to incorporate into the final project.
