There has been a lot of excitement about the use of 3D printers in education, but educators can have trouble both getting started with the technology and figuring out what to do with it. This two-class certificate covers both aspects, starting with how the technology works and then moving on to how to use it effectively. If participants already have 3D printers, the instructors will customize the class as much as possible so participants can follow along on the hardware they have. If a participant does not yet have access to a 3D printer, the instructors can help with helping participants define criteria to make decisions about appropriate hardware to buy.
   The intro class (recommended to be taken first) covers the entire 3D printing workflow with a focus on open source and free software. The market is somewhat fractured and different 3D printers vary somewhat in their operations there are not a lot of standards in the industry yet, but the instructors will guide participants through what the options are and where to learn the details of operation of their particular existing or planned hardware.
   The second class then builds on this knowledge to think about how to help students create their own exploratory models, or how to create models that a teacher can create to help students visualize an abstract concept. Participants will use some of the software covered in the Intro to 3D Printing class to create several different types of 3D printable models, and will discuss the details of how to print their design on the 3D printer they already have or plan to acquire in the future.

Individual Courses

Introduction to 3D Printing

3D printing has been hailed as a solution to all manufacturing problems. Obviously that is exaggerated, but what is it good for (and when is traditional manufacturing still the better choice?) In this course you will learn how to separate the real promise of the technology from the hype, and understand the workflow for a consumer-level 3D printer. You will become familiar with some typical online databases of objects available to print, and get a bit of experience with free or open-source software for all stages of the process. This class will be primarily focused to introduce you to the tools of the open 3D printer ecosystem, but the principles will apply to consumer  3D printers in general.

3D Printed Science and Math: Visualizations and Experiments

A 3D printer can be used to teach science and math in two ways: when a teacher creates an accurate 3D model of a concept for students to handle, or to design a “starter set” model that students can then alter and use as the basis for explorations. The instructors will impart ideas for developing appropriate content of concepts ranging from kindergarten to grad school and will teach participants to use the free and open source 3D modeling program OpenSCAD. The class assumes participants already know the basics of using a 3D printer, from the UgotClass “Intro to 3D Printing” or equivalent experience.

Question MarkAbout online learning

Online learning is a fun, enjoyable and very productive way to learn. Millions of people are learning online each year. You will engage with the instructor and other participants. You will get to know your instructor and other participants. You may make friends.  It’s easy. It’s fun. 

GearsHow the Course Works

It is easy to participate in your online course. After you register, you will be given a web address to go to get into your online classroom.  You will have a password and use your email address and password to gain access.

Once inside the online classroom, here’s what you can expect.

CalendarParticipate when you want

You can participate any time of day or evening. The online classroom is open 24 hours a day, 7 days a week.
There are no live real-time requirements or meetings. You decide when you participate.
For the best learning, participants should log into the course on 2-3 different days of the week.

ChecklistWhat you will do

For each Unit, you will:

  • Access the online readings
  • Listen to the audio presentation for the Unit and view the slides
  • Take a self-quiz to see how much you have learned
  • Engage in written online discussion with your instructor and other participants

For best learning, you should make one or more comments at 2-3 different times each day.

The content (readings, audio lectures, slides) and self quizzes are accessible for the entire course, so you can work ahead, or go back and review again, at your convenience.


The Discussion for each Unit lasts one week. All comments are made in writing and can be made at any time of the day or night.

Your instructor will log into the Discussion area at least once a day and answer questions, make comments, and respond to comments by you and the other participants.

We encourage you to make 2-3 comments each day to maximize your learning and enjoyment of the course.

It’s easy. It’s fun.

About Your Instructors

Joan Horvath and Rich “Whosawhatsis” Cameron are the co-founders of maker technology consultancy Nonscriptum LLC ( and previously were respectively VP of Business Development and VP of R&D at a small Kickstarter-funded 3D printer company. They collaborate on books for Apress, most recently “The New Shop Class.” Joan’s experience includes a 16 year stint in the aerospace industry, adjunct positions at several universities, and consulting in a wide variety of circumstances. She has degrees in Aeronautics and Astronautics from MIT and an Engineering MS from UCLA. Rich is an open-source 3D printer guru who designed one of the early open source 3D printers, the Wallace, and later the commercially-available Bukito.
