During the application process, if we receive more interest than there are spots in the class, we will run a lottery to determine who will be accepted.
Notification of class status will be made at the start of the fall semester.

“​Design for 3D Printing​” (15.S20) provides an extensive overview of Computer-Aided Design (CAD) software including Onshape, Fusion360, SculptGL, and InVesalius and their importance in the additive manufacturing, aka 3D printing, and “maker” industries. Students will get experience using CAD software to design parts for different applications and 3D printers.

Participants will learn and practice the fundamentals of CAD software, then explore opportunistic techniques in designing parts to be manufactured via 3D printing. Each student will design and print over five parts using ProtoWorkshop (located in the Trust Center, E40-160) and other resources found on the MIT Mobius App.

The objectives of this class are to introduce students to useful computer-aided design software and “dig deep” into their applications in industry. After this class, students will be confident in designing, 3D printing, and redesigning models for different applications, technologies, and 3D printers. ​

Design constraints from different 3D printers and technologies include supporting walls, holes, connecting parts, horizontal bridges, pin diameter, overhangs, unsupported walls, embossed and engraved details, machine tolerance, minimum features, and aspect ratios.

Students will also learn how designs change when making molds, fixtures, guides, prototypes, and end-use parts. The skills learned will be directly and immediately applicable to a number of classes on campus including 15.351 “Intro to Making,” MAS.863/4.140/6.943 “How To Make (almost) Anything,” and 2.810 “Manufacturing Processes and Systems.”

Normally, the class uses lectures, homework, videos, and in-class work time.

Most classes will start with a quick introduction to the topic of the day, followed by activities such as inventing challenges, 3D printing challenges, and team project time with one-on-one coaching by the instructor.

Students will have access to a Makerbot Replicator+ and a Fortus 380mc in the MIT ProtoWorkshop during class and can attend guardian office hours to use printers outside of class. Guardian office hours can be found on the MIT Mobius App.

When an activity requires a team, 2-3 students will join up as a team that will be formed in class. Each team should then divide and conquer and each student will need to own a part of the project.


COMMUNICATING EFFECTIVELY: Students will learn to present and explain their ideas with 3D models. Students are expected to ask questions frequently to avoid falling behind.

RESEARCH: Students will be able to locate and critically evaluate information.

ACCOUNTABILITY: Students are expected to attend all classes, complete any required reading, and turn in assignments on time.

None. This class is open to any novice designer, engineer, or entrepreneur, undergraduate and/or graduate, from any course of study.

Class size is limited to a maximum of 15 students. The class is by application only. If there are more applicants than we can accommodate, we will select the cohort by lottery.

As this is a hands-on, project-based class, no listeners will be accepted.

Work done in the class is purely for academic purposes. There is no explicit, or implicit, agreement that teams in the class that reuse the material developed in the class are in any way entitled to a share of equity in a new venture that uses material developed in the class. All output from the class is deemed to be public domain unless explicitly specified and agreed to by the instructor.

1st year MBA students CANNOT take electives past the MBA core in their first Fall semester the year they arrive at MIT. You may apply to the Spring session in your first year – or the Fall or Spring session in your second year.
