3D Printing In The Classroom

3D printing can add a new dimension to the classroom (pun intended).

While the technology is not yet "mature", you are now seeing 3D printers in office supply stores & Fry's Electronics. It's time to start looking at how this new medium can enhance your students engagement and understanding.

How 3D Printing Works

Dr. Martin Leary hosts this short, non-technical explanation of how 3D printing works and what you can do with it. While the printers come in many shapes, sizes, and prices(!), the basic concepts are the same.

Managing a classroom 3D printer

This blog post talks about how one teacher manages one 3D printer and "lots" of things to print - 15 new items out of one class. Other posts on this blog talk about the benefits of bringing a 3D printer into your classroom and showcases student projects.

3D Printing in the Classroom

Kathy Schrock has put together a comprehensive list of resources, lesson plans and additional videos related to 3D printing in the classroom.

7 benefits of using 3D printing technology in Education

This blog post from Makers Empire goes into detail on 7 good reasons for bringing 3D printing into the classroom:

  • Creating inventors
  • Bringing art back
  • Engaging reluctant learners
  • Creating responsible digital citizens
  • Making everything hands-on
  • Building school camaraderie
  • Solving real-world problems

Teacher Tip: Print everything in white

At a conference, a teacher mentions that she printed everything using white filament. When I asked why, she replied that it was faster than constantly switch out filament colors and made it easy to print out multiple items at once.

She found that permanent markers work great on white PLA. The students could "finish" their prints in whatever color or colors(!) they wanted. And all she had to stock was white PLA.

The three basic 3D-printing processes

Bart Van der Scheuren, of the Belgian 3D printing company Materialise, does a good job of explaining how the three main 3D printing technologies work.

Fused-deposition modeling
uses an nozzle to lay down the part one-layer-at-a-time using plastic or other media
Laser sintering
uses a laser (or in some printers a fine spray of glue) to fuse powder into solid shapes
Stereolithography
uses a laser is used to fuse a very special liquid into plastic.

So You're a Teacher with a 3D Printer... Now What?

You now have a 3D printer for your school and you've finally figured out how to get it to work. Once you've successfully supplied your school with all the key chains, name tags, and Yoda heads they will ever need, there's a lot more you can do...

One option is creating a 3D Design Problem Bank, where adults (faculty, maintenance workers, parents, etc.) submit problems in need of a 3D designed solution and students from different grades and settings are given the chance to choose problems they want to solve. Working together, student and adult both play a role in defining the problem, brainstorming first steps, and generating gradually improved iterations of the 3D printed solution.

Brookwood's 3D Design Problem Bank

Here's the actual site referred to in the "Now What?" article. Built using Weebly.com, a web site hosting service specializing in online shopping, this site allows adults (faculty, maintenance workers, parents, etc.) to submit real world problems and students to solve those problems using 3D design and printing.

Check out the "Create A Problem Bank" link where you can get some background on this site and how it benefits students; and where to find help to build your own Problem Bank site.

Open Book on "Low-cost 3D Printing for Science, Education and Sustainable Development"

This book gives a reasonable, first overview of current research (as of 2013) on 3D printing. It aims to inspire curiosity and understanding in young scholars and new generations of scientists to motivate them to start building up their own 3D printing experiences and to explore the huge potential this technology provides. Topics include...

  • A Practical Guide to Your First 3D Print
  • Plug-n-Play, Do-It-Yourself Kits and Pre-assembled 3D Printers
  • 3D Modeling with OpenSCAD
  • Low-cost 3D Printing for Science

Printing A Bridge

What happens when you combine a 3D printer with an industrial robot? You get something that can print things like a pedestrian bridge. MX3D is working on a project that will do just that in Amsterdam.

Materials that Can Be 3D Printed at Home

When it comes to 3D printing and the materials that can currently be printed in a home or classroom environment, the range available might surprise you. Everything from plastic to nylon to ceramics to "wood".

PLA plastic filament is a "best" choice for a classroom environment.

11 Food 3D Printers to Feed the Future

While most 3D printers today "print" with plastic, there is a lot of experimentation and new products that can print on other media. If you can push it out of a nozzle - think frosting, chocolate, cookie dough, & jelly - you can print with it. Check out these incredible and editable results.

Sources For Help

Not sure where to start? Check with your local Maker Space or university.

There are people in your area with 3D printers who would be glad to demonstrate them, assist you in choosing the right one for your needs, and help with things just aren't working.
