Problem Statement
''In one or two sentences, describe the project that your group will be working on. Identify what CDIO phase (Conceive, Design, Implement, or Operate) your group will complete in this project cycle.''

For this project cycle I will be working on the MakerBot project (Implement).

Project Plan
Briefly describe your group's plan for the next 4 weeks, including major tasks that will be completed each week.

Week 1 Narrative
''Describe in detail what you did for your team during the week (and weekend). Compare your task (from CDIO discuss page) with what you actually did.''

This week I learned more about the MakerBot and looked at team pages for this project from the previous group and previous semesters. I have seen the MakerBot being used before during engineering club but I have not been certified yet because of it is in constant use. But I found some information online about polylactic acid and its different uses. I also looked at a video of a man showing how it works.

Week 2 Narrative
''Describe in detail what you did for your team during the week (and weekend). Compare your task (from CDIO discuss page) with what you actually did.''

This week was spent thinking of a design for our test with the different colored PLA material. We agreed on thinking of different ideas and seeing which would be best for testing the strength of the material. This week I thought of a design using a C-Clamp, some type of strong adhesive adhesive and a ring stand that I found in the class. The ring stand has a horizontal rod component that sticks out and is adjustable to different lengths. My idea is using the C clamp to secure the base of the ring stand to the table, we glue two ends of the PLA to the rod at the same point of the rod and place a hook on the bottom of the PLA. We then attach weights to the hook. and test the strength that way.

Week 3 Narrative
''Describe in detail what you did for your team during the week (and weekend). Compare your task (from CDIO discuss page) with what you actually did.''

This week I continued looking for a feasible way to test the PLA filament by vertically hanging it. The ideas we exchanged this week seem to all have faults that rule them out. We will have to decide on a final design soon despite any minor faults it may have so we can perform the actual tests on the filament.

Week 4 Narrative
''Describe in detail what you did for your team during the week (and weekend). Compare your task (from CDIO discuss page) with what you actually did.''

My task for this week was to build another prototype similar to the one that we agreed on using to test the filament and conduct my own tests on the red, black, green, and gray filaments. I used 10lb weights to test the strength of each filament starting with one 10lb weight for each filament and if the filament did not break, adding 10lb weights one by one until the filament did break. I did ten trials for each filament color and averaged my results in the table below.
