Week 9 - Fady Riad

 This week consisted of testing pressure sensors connected to our lab setup to make sure they work. I worked on 3D printing parts for our team since the 3D printing lab does not want to print the parts in the size we want. The first few prints failed completely since they were too small. After some research and watching how to design and 3D print parts and after some testing I was able to print the parts we needed with the adjusted design and the adjusted settings. The parts were dropped off in the lab on Tuesday for Kierstin to drill and test. Unfortunately, the parts were missing after a few hours and I ended up working on printing new parts and removing supports again. The parts are really small and fragile and were not able to get the supports off easily but with a little bit of sanding and working around it hopefully, these parts work in our lab.

This layout was not successful since the supports were too small to take off without breaking the stem.

After switching the orientation and changing the support percentage to 5% instead of 15% the supports were easy to take off and the part still functions as intended.

Parts that are reprinted after the first tries went missing. I printed multiple since the holes are not accurate when 3D printed and need to be drilled to make sure we have the right size.

I researched how to show two DMMs on the Elvis II application but I do not think it is possible since there is only one voltage output. We have two pressure sensors in our lab test which need to be measured simultaneously so I do not think Elvis II would work for us and will be using multimeters.

What worked:

Pressure Sensors

3D printed parts

What did not work:

Elvis II

This is the list of what worked and what did not work for me. I took a look over my team's lists as well to make sure we are all on the same page.
