# 3D Printing of Open Source Hardware for Science (3DPOSHS)
## Part 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 open source 3-D printers to fabricate the device.
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. Forbes explains why 3D printing is such a big deal.
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.
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.

### Impact Factor

The impact factor (IF) of an academic journal is a measure reflecting the yearly average number of citations to recent articles published in that journal. It is frequently used as a proxy for the relative importance of a journal within its field. In any given year, the impact factor of a journal is the number of citations, received in that year, of articles published in that journal during the two preceding years, divided by the total number of articles published in that journal during the two preceding years. So are articles in that journal getting cited fast after publication. * Because citation counts have highly skewed distributions, the mean number of citations is potentially misleading if used to gauge the typical impact of articles in the journal rather than the overall impact of the journal itself. For example, about 90% of Nature's 2004 impact factor was based on only a quarter of its publications, and thus the actual number of citations for a single article in the journal is in most cases much lower than the mean number of citations across articles.
* The strength of the relationship between impact factors of journals and the citation rates of the papers therein has been steadily decreasing since articles began to be available digitally.
* Open access improves citation rates. , Princeton

There is a big change with time based on popularity of the subject.

### h-index

The definition of the index is that a scholar with an index of h has published h papers each of which has been cited in other papers at least h times. Thus, the h-index reflects both the number of publications and the number of citations per publication. The index is designed to improve upon simpler measures such as the total number of citations or publications. The index works properly only for comparing scientists working in the same field; citation conventions differ widely among different fields.
Input data comes from subscription-based databases such as Scopus and the Web of Knowledge provide automated calculators. Harzing's Publish or Perish program calculates the h-index based on Google Scholar entries.
You can also somewhat predict your future hindex. The variables you have control over are variables are number of articles, number of distinct journals and number of articles in top journals.
To compare to older colleagues: The m-index is defined as h/n, where n is the number of years since the first published paper of the scientist; also called m-quotient. You can also subtract the difference in your starting years from their Google Scholar profile.
