Layered Fabric Printing

A Layered Fabric 3D Printer for Soft Interactive ObjectsHuaishu Peng, Jennifer Mankoff, Scott E. Hudson, James McCann. CHI ’15 Proceedings of the 33rd Annual ACM Conference on Human Factors in Computing Systems, 2015.


In work done collaboratively with Disney Research and led by Disney Intern Huaishu Peng (of Cornell), we have begun to explore alternative material options for fabrication. Unlike traditional 3D printing, which uses hard plastic, this project made use of cloth (in the video shown above, felt). In addition to its aesthetic properties, fabric is deformable, and the degree of deformability can be controlled. Our printer, which works by gluing layers of laser-cut fabric to each other also allows for dual material printing, meaning that layers of conductive fabric can be inserted. This allows fabric objects to also easily support embedded electronics. This work has been in the news recently, and was featured at AdafruitFuturityGizmodo; Geek.com and TechCrunch, among others.

Videos to flip through

Much of the work here is by Stefanie Mueller, Patrick Baudisch and others. I didn’t want to assign too many papers by the same group, but these videos are worth browsing! There are some other authors represented here too.

3D Printing for Social Good Final Project

The goal of the final project assignment is to give you an opportunity both to become comfortable using a 3D printer and to think about novel research that can be done with the printer and begin defining and executing on such a problem. It is very open ended, and there is no single ‘right’ answer to what makes a successful projects.

This project is divided into three pieces.

1) The first is a proposal. This is an individual proposal. We will spend 3 minutes per proposal in class hearing your ideas, and you will turn in a brief description of them on Canvas.

  • Your proposal should involve some sort of fabrication, and be in one of the areas we have explored during class (including both application domains and advances such as printing with new materials). The rest is up to you, though I am happy to provide guidance.
  • It should be no more than one page long, including references (which are optional)
  • It should be organized as follows: Promise (what opportunity it creates); Obstacle (why is it currently not possible); Solution (what you will do).

2) The second is team formation. Each of you will be asked to assign a points to every proposal indicating your interest in it.  You have 20 votes, and may apply up to four for any one project. You may not vote for your own project. Approximately 5 of the projects will be selected as starting points, allowing teams of 3-4 students to be assigned based on approximate best match. Swaps will be allowed with permission of the instructor, once both teams agree.

3) The final project should include a two page report and a final presentation. The presentation should include a prototype (fabricated), discuss the promise, obstacle, and explain your solution process.

Build a 3D Printer

Learning Objectives:
– Practice assembling a moderately complex electromechanical device
– Learn the details of how your printer operates

Build a 3D printer from a kit. For this assignment you are being asked to demonstrate the basic operation of your machine by doing the following:

  • Moving each axis (x, y and z) independently
  • Homing (all axis)
  • Printing a test object — specifically, the “0.5mm-thin-wall.stl” file from the “Essential Calibration Set” (posted to Thingiverse by coasterman as: http://www.thingiverse.com/thing:5573).

Turning Your Project In

This assignment will be peer graded on a pass/fail basis. To turn in your completed assignment find another student in class to certify that you have fulfilled the requirements above and have them send me an email by the end of the day the assignment is due.
