156B Week 1

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Reviewed several design ideas with sponsor for nozzle and manifold designs

  • Will 3D print prototypes ASAP to test on the scope

  • Gas distribution test is currently planned for next Tuesday, maybe earlier if we can get time on the scope.

Accomplishments from Previous Week

• • 4 prototype designs were created in Solidworks

    • 2 Prong Manifold Design

    • Detachable Manifold

    • Half-moon Manifold

    • Swappable Clamp Design

  • Test nozzles for gas distribution test are cut and ready.

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • 3D print all nozzle and manifold prototypes - Edwin

  • Refining CAD models - Kuanren(William)

  • Conduct gas distribution experiment and analyze results    - Dylan and Layton

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Sponsor: Goal is to quickly prototype as many different nozzles as possible

  • Reaction: focus will be to 3D print all possible designs (small pieces so cost is not an issue)

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Instructor: use all available space to minimize strain on components

  • Reaction: designs will reflect this consideration

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

• • 3D printed pieces for nozzle and anker might be too fragile

  • 3D printer uses proprietary materials

    • May not be vacuum compatible

    • Not conductive

  • Sealant or glue might need to be used to assist with nozzle attachment

  • Carbon coating for non-conductive material can be easily scraped off

Resources or Information Required but not Available

• • Still waiting on scope availability in order to test gas flow with prototypes

  • Some proprietary plastics from high end 3D printers have limited material information online (e.g. outgassing data), so we have to test through trial and error.

Schedule

• • Gas Distribution Experiment done by 4/11

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • 5500 remaining

  • 0% spent

Progress on Report and Webpage

• • Individual component analyses are being written this week
