3D Printing in the Classroom
Engaging learning environments often provide students multiple opportunities for the perception and comprehension of academic content. One such method is to pair models or manipulatives with text, audio, or video. For example, tactile representations from a literature selection, math manipulatives, hands-on science labs, or even historical artifacts from a social studies class. This is not always possible as at some point physical representations of objects may be too big, too small, too fragile, or even too dangerous. 3D printing provides a pathway to make physical representations of almost any conceivable object, concept, or idea.

What is 3D Printing?

3D printing is the process of converting a multi-dimensional digital file into a three-dimensional physical object. Projects can be imported from online community libraries or by replicating an item with a specialized scanner that creates a digital file of a real object. Users can also create custom models by using drag and drop programs such as TinkerCad or 3DTin. 3D printers use a process of depositing multiple layers of filament to create objects made of plastic, rubber, metal, wood, wax, Cacao powder, or just about any media or substance depending on the type of 3D printer.

UDL in 3D

When designing flexible learning environments that meet the needs of all students, 3D printing is a natural fit. Through a Universal Design for Learning lens 3D printing:

Promotes student engagement.
  • Collaborative activities help students connect with and work with others.
  • Provides a method of creating resources and supports for task completion.
  • Recruits students' interest.
Provides an alternate means of representation that can increase perception, comprehension, and reduce language barriers.
  • Presents a medium to anchor instruction or teach prerequisite skills.
  • Provides a mechanism to compare and contrast objects.
  • Promotes understanding across languages.
Provides options for expressive skills.
  • Compatible with most computer-based design programs and assistive technologies.
  • Flexible to allow students an alternative method for expressing thoughts that cannot be articulated through print, speech, or other multimedia.
  • Motivational for students to build skills and become architects, engineers, and inventors, limited only by their imagination.

3D Printing for Students with Disabilities

Science, technology, engineering, and math (STEM) curricula often rely on the use of imagery for conveying information. Images from telescopes, microscopes, topographical maps, and satellites help students grasp the relationships between concepts and objects and are effective companions for printed text. Not having access to the same images is a barrier for students with vision impairments. Students with learning disabilities, autism, intellectual disabilities, and traumatic brain injuries may also benefit from the additional tactile and spatial information provided by a 3D object. To eliminate barriers, consider:
  • Converting 2D images to 3D printed objects.
  • Adding Braille to manipulatives.
  • 3D printing objects that are viewed through a microscope.
