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.

Unit 1: What is a 3D Printer?
-Understanding additive manufacturing and how it is different from traditional subtractive manufacturing
-How 3D printers work – different types
-The 3D printing workflow: modeling, slicing, printing
-The state of the art in consumer printers
Unit 2: Getting a 3D Model
-Free and/or open source modeling software (Tinkercad, OpenSCAD)
-Scanning in a model
-The model databases (Thingiverse, YouMagine)
Unit 3: Slicing Your Model
-Design rules for consumer 3D printers
-What is slicing?
-Infill, overhangs, rafts, skirts
-Finding and using free and open source slicing software (MatterControl, Cura)
-Materials choices for consumer 3D printing
Unit 4: Using Your Printer
-Classroom application examples: learning by making
-Applications for teaching the visually impaired
-Using a 3D printer for home tinkering
-Bigger picture and the future: medicine, construction, more.
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.
How 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.
Participate 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.
What you will do
For each Unit, you will:
For best learning, you should make one or more comments at 2-3 different times each week.
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.

About Your Instructors
Joan Horvath and Rich “Whosawhatsis” Cameron are the co-founders of maker technology consultancy Nonscriptum LLC (www.nonscriptum.com) 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.
