29. Bill of Materials
Jack

30. Updated Bill of Materials (1 of 3)
Jack explain why it’s blank for now and NOT INCLUDED in budget

31. Updated Bill of Materials (2 of 3)
Jack
sheet
fittings
tubing

32. Updated Bill of Materials (3 of 3)
Jack Explain why it’s blank and that there is also the possibility of us making our own out of scrap material and a few bolts/screws, which would be inexpensive

33. Potential Material Sources
Electrical components from other RIT labs
Past MSD teams leftover supplies
Luer Locks
Luer Lock Adapters
Zip Tie clips
Custom 3D printing fixtures
Avoids buying in bulk
Control over dimensions
Jack

34. Procurement and Fabrication
Jack

35. Procurement Current Items Purchased: Honeywell Pressure Sensors (2)
Protoboard
Current Items Owned:
40 feet of 2mm tubing
Honeywell Pressure Sensor (2)
Jack

36. Fabrication Machines and Tooling:
MACH C Water Jet (flowwaterjet.com)
2m x 2m [6.5’ x 6.5’] Overall Dimensions
2D DXF file exported from solidworks
Bonding Material (clear, water-thin solvent cement)
1 min. working time, 2 min. fixture time, 24 hr 80% strength set time
3D Printer
Cost - first 50 grams free, $0.03/gram after
Lead - self-operated machines
Material - PLA or ABS
Difficult Assembly/Fabrication steps:
Sealing the top
Drilling holes without spider webbing the material
Jake

37. Priority Fabrication Need to make the Pressure Sensors operable
3D Printed T-Tube Connector
1 in to 1 in to ¼ in
Connect the tubing, luer lock stopcock, and the electronics
Assemble the compliance tanks
Attach all tube fittings, air valve, and pressure bulb
Create the external resistor/clamp
Jack

38. Benchmark set-up
Jack - talk about DI water and problems with air; we can either invert or we have to include a valve

39. Preliminary Test Plan Ideas
Jack

40. Test Plans (based on Engineering Requirements)
Jack

41. Pressure Sensor Test Plan
Obtain a piece of tubing 12 inches in length
Fill with DI water and cap each side
Pressure in the tube is 12 inH20
Measure the pressure with the pressure sensor
Compare the recorded value vs. the theoretical value
Jack

42. Resistor Test Plan
Resistance: TBD pending access to a pump and working pressure sensor.
Resistance: Calculating the resistance based on draining a known quantity of water (Calibration curve).
A hose clamp can be modeled as a Clamp Valve.
