Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Tested cleaning methods on print trays using various power tools from the machine shop & Harbor Freight
Mostly involved rotary wire wheel tools, rotary abrasive wheels, heating (using a heat gun), scraping tools
Accomplishments from Previous Week
Determined that rotary tools caused the print resin to heat up and adhere more strongly to the perforated holes on the print bed
Heat was the best mechanism to remove resin easily and caused resin to be removed from perforated holes with one use of a punching tool
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Purchase the correct medium (10/20) to use with the tumbling apparatus for cleaning resin off print trays
must machine/cut a print tray to smaller sections to fit into the tumbling chamber
Research a variety of rubber materials to test with with an arbor press for removing resin from the perforated holes
Use a chisel tool to test different motions linear oscillatory motion for scraping off resin
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
03/11
Look into paint chiseling methods/tools for removing resin
Use jewelry tool suppliers for mediums to test in the tumbling method
Rectangular brush under oscillating motion
Mentioned they would ask about lending the team a Flir Tool for measuring temperature
More dangerous methods for potential exploration:
dry steam
Will provide trays to solidify concrete definition of: clean, satisfactory clean, unacceptable clean, damaged & unusable print tray

03/05
Ask Chris Cassidy for USB microscope (Chris advised it wasn't worth finding the drivers for it because the technology is quite outdated)
Solidify definition on clean and unclean (3D Systems will provide us the defined plates as soon as their printer is available)
Test freezing method to see effects on the resin (froze the printing trays in the fridge)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
N/A
Risks and Areas of Concern
Safety issues when heating the resin (need for proper way to handle fumes)
Amount of force needed to remove print resin from perforated holes when using a conforming/rubber material
Finding a way to test sandblasting on the print beds

Schedule
Describe upcoming milestone
Update Gantt chart.
Budget (list amount spent and amount remaining)
Spent: $100.45
Remaining: 11699.55
Progress on Report and Webpage
Will update after receiving definition of clean vs unclean plate, damaged vs undamaged plate, and finishing the remaining risk reduction tests
