MECE 4606 Digital Manufacturing – Spring 2018
Mondays 1:10-3:40, Classroom: 750 Schapiro Cepser
This course examines a variety of digitally-controlled manufacturing processes that convert computer models directly into physical objects. Topics include: Additive manufacturing processes, CNC, Sheet cutting processes, Numerical control, Generative and algorithmic design. Topology Optimization, Broader social, economic, legal and business implications will also be reviewed. Course involves both theoretical exercises and a hands-on project.
On completion of the course, you should
- Be familiar with the product realization process and its documentation (ABET c).
- Be familiar with basic tools of design and manufacturing such as CAD and machine tools. (ABET k).
- Function effectively in a team. (ABET d).

- Topology Optimization assignment: 10%
- Food printing assignment: 40%
- Final Exam 30%
Every student receives four days (96 hours) "grace allowance" for late submissions. These hours can be used for any reason whatsoever, including but not limited to religious observation, job interviews, conference trips, sport competitions, or medical issues. There is no need to justify the use of grace hours.
With every assignment submission, each student should list total number of grace hours used so far and total number of hours remaining. These numbers should add up to 96.
A team submission late by X hours depletes X hours from each team member.
Once grace hours are depleted, a penalty of 5% for every day or part of a day late will be incurred, unless the student provides a written note from their advising dean supporting an excused delay.
Improper, irresponsible or unsafe behavior will result in loss of laboratory privileges in MechE Lab, Makerspace, and the MechTech Lab [Mudd 273]. Due to the high fabrication content of this course, this policy will be strictly enforced. Grades may also be used to penalize safety.
Students may copy any part of someone else's design work (including from other students, external sources, previous years, the Internet, etc.) but they must explicitly cite the source and provide a complete and full citation. In this case they will be graded on their added value compared to the source. If copying text verbatim, put copied text in quotes and cite source. If paraphrasing someone else's idea, cite original source.
Copying without attribution is considered plagiarism and a violation of academic integrity.
Use of third party software libraries
Assignments are designed so that third part libraries are not needed. If a student wishes to use an external library, permission should be requested publically on Piazza. Any library used must be cited in the report.
Students with Disabilities
If you are a student with a documented disability on record at Columbia University and wish to have a reasonable accommodation made for you in this class, please contact the instructor immediately.
