The course will explore the initial design and further development of open-source instrumentation as it relates to the build of a RepRap form of 3D printer. Each student will build a customized 3D printer and will learn all hardware, firmware and software for operating it. The printer will then be used in the completion of a series of projects in the students' field of interest.\n\n== 3D Printing Technology ==\n\n(Spring 2023)\n\n* ''10:00 am - 10:50 am, ''\n* Science Center 109\n* January 23, 2021 - May 10, 2021\n\nInstructor: [[User:MarieFarson]]\n\n'''Why 3-D Printing?''' A recent report from data company Wanted Analytics found that in one month [https://web.archive.org/web/20160403131121/https://wantedanalytics.com/analysis/posts/demand-for-3d-printing-skills-soars?utm_campaign=9_4_2014_3dprinting&utm_medium=google+&utm_source=google+ 35 percent of engineering job listings] from a variety of fields, including biomedical, software, and transportation industries, required applicants familiar with 3-D printing.[http://theinstitute.ieee.org/career-and-education/career-guidance/thirtyfive-percent-of-engineering-jobs-now-require-3d-printing-skills] Forbes explains why [https://www.forbes.com/sites/louiscolumbus/2015/03/31/2015-roundup-of-3d-printing-market-forecasts-and-estimates 3D printing is such a big deal].\n\n'''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. [http://www.indeed.com/salary?q1=linux&q2=microsoft+windows]\n\n== Learning Outcomes ==\n\n# To demonstrate a depth and breadth of knowledge about open source hardware and software, especially as it relates to 3D printing technologies ([[ENGR242|CWLO]] 1 and Engineering DLO 7)\n# To develop critical thinking skills through the trouble shooting process involved in hardware and software development ([[ENGR242|CWLO 2]], Engineering DLO 1 and MNS GESL criteria 2.1)\n# To demonstrate effective communication skills working on collaborative design projects and appropriate posting of open source projects ([[ENGR242|CWLO 3]] and Engineering DLO 4&6)\n# To broaden students’ awareness of the needs and challenges in east Africa in developing capabilities at the local level for locally produced social impact([[ENGR242|CWLO]] 5 and MNS GESL criteria 1.4)\n\n'''Credits''': 4.0 SH\n'''GESL'''\n\n== Required Course Material ==\n\n[[Image:OSL.jpg|thumb|left]]\n\n '''There is a $100 lab fee for this course.''' This fee will be used to purchase expendable materials for you to build your printer during the course. You must '''provide your own SD Card''' for storing your print files. You should plan on $25 or more additionally to '''purchase your choice of filament''' to use with your printer. You also have the option of buying a set of hardware components totaling about $795 at the bookstore to use for your build. If you use your own components, then at the end of the course you keep the printer you built in the course. The printer will be similar to the image above, but the design is constantly evolving.\n\nTextbook: J.M. Pearce, ''The Open-Source Lab'' (Elsevier,2014). Other reading will be handouts in class, on-line reading, and emailed pdfs. See hyperlinks in schedule.\n\nLink to online portion of textbook:\n[http://store.elsevier.com/coArticle.jsp?pageid=18200010&utm_source=Joshua+Pearce&utm_medium=marketing&utm_campaign=Open-Source+Lab+Free+Access Online portion of textbook]\n\n== Course Organization ==\n\nThis course will be run as a lab course with lectures. 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 labs and projects. Each student will be responsible for building a RepRap Jellybox 3-D printer to use to complete the projects. Students will be responsible for giving short presentations on their projects on each sub-topic in front of the class at the end of the semester.\n\n== Grading Policy ==\n\n<font>Grades will be based on the following:</font>\n\n{| class=\"wikitable\" border=\"1\"\n| <font></font>Jellybox build\n| <font>10</font>\n|-\n| <font>Appropedia Page/mini projects</font>\n| <font>10</font>\n|-\n| <font>Quizzes</font>\n| <font>5</font>\n|-\n| <font>Educational Aide Project</font>\n| <font>10</font>\n|-\n| <font>Scientific Instrument Project</font>\n| <font>20</font>\n|-\n| <font>OSAT Collaborative Project</font>\n| <font>20</font>\n|-\n| <font>Big Money Project</font>\n| <font>25</font>\n|-\n| <font>'''Total Percentage'''</font>\n| <font>'''100'''</font>\n|}\n\n=== Late Assignments ===\n\nDeduct 10% per day, up to 5 working days, then 0 grade. Only exception is for '''excused''' absences. Missed projects will result in a zero for the assigned work. Quizzes on the readings cannot be made up, ever.\n\n=== Course Policies ===\n\nAppropriate behavior, attendance, participation and collaboration with your peers on group assignments is expected. All assignments are to be completed by the beginning of class on the due date, unless you make other arrangements with me at least '''24 hours''' in advance.\nCollaboration/Plagiarism Rules\nStudents are strongly encouraged to learn while helping fellow students learn. Collaboration is encouraged on the group project but individual projects and exams must be completed alone.\n\n== Academic Integrity ==\n\nA Principian is expected to pursue a life of integrity (see the Principia Pledge and the Principia Community Commitment.) Therefore academic honesty is essential to a Principia College education. Academic regulations and procedures are governed by University policy (see Principia College Catalog 2020-2021). Any act of academic dishonesty will result in a failing grade for the class.\n\n* [http://catalog.principiacollege.edu/principia-standards/academic-integrity-performance/ Academic Integrity]\n* [http://catalog.principiacollege.edu/principia-standards/principia-community-commitment/ Community Committment]\n* [http://catalog.principiacollege.edu/principia-standards/matthew-code/ Matthew Code]\n\n== Course Schedule ==\n\n''' Please Note: Readings will be updated periodically before we get to the module.'''\n\n{| class=\"wikitable\" border=\"1\"\n! align=\"CENTER\" | '''Date'''\n! align=\"CENTER\" | '''Class'''\n! align=\"LEFT\" | '''Class description'''\n! align=\"LEFT\" | '''Assignment - due next class'''\n|-\n| align=\"CENTER\" | 1/23\n| align=\"CENTER\" | 1\n| align=\"LEFT\" | Intro to class, projects and build assigned\n| align=\"LEFT\" | Syllabus, Schedule, [[ENGR242#Module 0: RepRap Build|M0.1]]\n|-\n| align=\"CENTER\" | 1/25\n| align=\"CENTER\" | 2\n| align=\"LEFT\" | Intro to 3D Printing Technologies, Intro to Safety, Crimping and Soldering\n| align=\"LEFT\" | '''Buy kit on [https://epayment.principia.edu/C23895_ustores/web/classic/store_main.jsp?STOREID=25&SINGLESTORE=true Marketplace]''', [[ENGR242#Module 0: RepRap Build|M0.2]], Online Quizzes in Canvas\n|-\n| align=\"CENTER\" | 1/26&27\n| align=\"CENTER\" | 3\n| align=\"LEFT\" | Get parts -Start Building Your 3D Printer!\n| align=\"LEFT\" | Watch videos\n|-\n| 1/28\n|\n| Blitz Build\n|\n|-\n| align=\"CENTER\" | 1/30\n| align=\"CENTER\" | 4\n| align=\"LEFT\" | Intro to RepRap software chain, printer build\n| align=\"LEFT\" |[[ENGR242#Module 0: RepRap Build|M0.3,M0.4]], Online Quiz\n|-\n| align=\"CENTER\" | 2/1\n| align=\"CENTER\" | 5\n| align=\"LEFT\" | Complete RepRap software chain, printer build\n| align=\"LEFT\" | [[ENGR242#Module 1: Introduction to OSH|M1.1]], Online Quizzes\n|-\n| align=\"CENTER\" | 2/3\n| align=\"CENTER\" | 6\n| align=\"LEFT\" | OSH definitions, development, business, printer build\n| align=\"LEFT\" |[[ENGR242#Module 1: Introduction to OSH|M1.2]]\n|-\n| align=\"CENTER\" | 2/6\n| align=\"CENTER\" | 7\n| align=\"LEFT\" | OS licenses, printer build\n| align=\"LEFT\" |[[ENGR242#Module 1: Introduction to OSH|M1.3]], Online Quizzes\n|-\n| align=\"CENTER\" | 2/8\n| align=\"CENTER\" | 8\n| align=\"LEFT\" | OS legal discussion, printer build, order filament\n| align=\"LEFT\" | Problem Solver\n|-\n| align=\"CENTER\" | 2/10\n| align=\"CENTER\" | 9\n| align=\"LEFT\" | Intro to Arduino\n| align=\"LEFT\" |'''Jellybox built''', '''PLAY WITH IT IN CLASS, Problem Solver'''\n|-\n| align=\"CENTER\" | 2/13\n| align=\"CENTER\" | 10\n| align=\"LEFT\" | In class build quiz, Intro to wiki- Appropedia, printer adjustments from calibration houses\n| align=\"LEFT\" |[[ENGR242#Module 2: Community|M2.1-3,5]], Create and populate Appropedia user page, [[Appropedia]], [[Example 242 User page]]\n|-\n| align=\"CENTER\" | 2/15\n| align=\"CENTER\" | 11\n| align=\"LEFT\" | Everyone's Done!
