  • Category:L3999 Fall2017


These two coupled courses on will run over Period 1 and Period 2.

Period 1: Introduction to 3-D printing of open source hardware for science.

Course Description

This course provides an introduction to the use of distributed digital manufacturing of open source hardware for scientific and engineering applications. Recent progress in this area has radically reduced the costs of scientific equipment, while enabling high-quality state-of-the-art customized experiments.

First this course will provide an overview of open-source hardware and technological development in theory and practice. Licensing issues will be explained. Both the use of free and open source design and manufacturing software and their user communities will be highlighted and demonstrated. Next, the course will detail the design, use and maintenance of the tools themselves and open-source electronics. In particular, the self-replicating rapid prototypers (RepRap) will be discussed in detail including: hardware, firmware, slicing and printer controller software for operating and maintaining the device. Finally the material properties, applications and ramifications of RepRap technology will be discussed along with the development of and other open hardware fabrication tools. Then, the technological evolution of the open-source digital manufacturing technology will be covered with a focus on developing innovation for improved performance and customization.

This will be a project-based course where students learn how to develop open hardware for their own experiments and assignments will develop students' skills through progressively more sophisticated design challenges. The final and most complicated challenge will be student-selected to assist their own research group and will make use of the Aalto FabLab to fabricate the device.

Credits: 5.0

Prerequisites. The course is meant for graduate students in science or engineering. While students in other areas with a strong interest in this topic are also welcomed they are expected to have a fundamental scientific understanding and be technically proficient.

Why Take This Course?

Why 3-D Printing? A recent report from data company Wanted Analytics found that in one month 35 percent of engineering job listings from a variety of fields, including biomedical, software, and transportation industries, required applicants familiar with 3-D printing.[1] Forbes explains why 3D printing is such a big deal. “50% of manufactured goods will be printed in 2060” according to ING

Why open source? You will make more money, because OS is more valuable. Recent analysis shows that jobs with the keywords "Microsoft Windows" have an average salary of $64,000, while jobs with the keyword "Linux" have an average salary of $99,000. [2]

Why open source hardware in science? Numerous studies have now shown that custom scientific hardware creates enormous value, enables more rapid development of science, better equipment and provides jaw-dropping ROIs for science funders.[3]

Course Organization

This course will be run as an intense seminar meeting as a group. Students will be expected to read the course material before class and actively participate in discussions. The majority of class time will be spent on projects in a flipped class format. Each student will be responsible for designing and in the final project building open source scientific hardware. Students will be responsible for giving short presentations on their projects on each sub-topic in front of the class.

Learning Objectives

  • Learn the fundamentals of additive manufacturing (AM) and 3-D printing with polymers, along with those for emerging materials (e.g., metals, ceramics, flexible materials, nanocomposites, biomaterials) and complex architectures.
  • Learn the fundamentals of free and open source hardware (FOSH) design, licensing, and culture.
  • Understand the maintenance, trouble shooting and operation of self-replicating rapid prototype (RepRap) 3-D printers.
  • Understand operating principles, capabilities, and limitations of fused filament fabrication (FFF)-based 3-D printing.
  • Understand the principles of "Design for 3-D printing" and compare and contrast additive processes with conventional manufacturing in terms of rate, quality, cost, environmental impact, social control and flexibility.
  • Gain hands-on experience with RepRap 3-D printers; use these machines to fabricate example parts of increasing complexity, post-process the parts, and study the results.
  • Become familiar with the complete workflow of open source AM, including computational design tools, firmware, software, file formats, toolpath generation, and characterization.
  • Understand how to make a new part and alter an existing part for RepRap 3-D printing for custom applications.
  • Study applications of distributed manufacturing using 3-D printing specifically scientific equipment
  • Understand the requirements to design open source scientific hardware
  • Understand documentation necessary to publish in the field of open source scientific hardware
  • Place open source 3-D printing in the context of the evolving distributed manufacturing infrastructure.

Grading

Grading: Grades will be based on 5 projects of increasing complexity.
