156B Week 3

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

• • Parts ordered for first prototype (Nicholas)

  • Refined design for first prototype (Team)

Accomplishments from Previous Week

• • Ordered parts (Nicholas)

  • Sponsor Approval (Armando)

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

• • Construct prototype (All members)

    • Design custom extruder tip for 3D printing (Kevin)

    • Talk to Chris Cassidy about 3D printer access for custom extruder tip and spools (Anny)

    • Design Spool Mount (Armando)

  • Inquire sponsor and possibly acquire filament and carbon fiber (Nicholas)

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

• • Talked about potential applications and possible ventures into business

  • Still interested in fiber reinforcement

  • Understood timeline of testing phases

  • Allotting full access to KUKA starting early February until the end of the quarter (Door Code)

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

• • 1/14/2016 (in person, after Design Proposal Presentation)

    • Have not met with professor since previous week's progress report

    • Hardened steel should be able to handle abrasive material

    • Cite sources

    • Might not need as much memory in microcontroller

    • Keep robot head moving at a constant speed to uniform filament extrusion

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • 1/14/2016 (feedback sheets, during Design Proposal Presentation)

    • Keep presentations concise, with less words, more diagrams/figures

    • Good CAD

    • Consider using Raspberry Pi, due comparable costs and increased functionality

    • Consider abrasion tests for extruders

Risks and Areas of Concern

• • Distance between filament feeder and the hot end of the extruder

  • Possible use to two extruders (coaxial)

  • Modifying custom nozzle to allow full embedding of fiber into the plastic

Resources or Information Required but not Available

• • Currently being addressed by sponsor

    • Door Code for Robotics Lab

    • Index Number

Schedule

• • Waiting for ordered parts to arrive, estimated 1/22/2016 (Nicholas)

  • Take measurements of ordered parts to begin manufacturing prototype (Anny)

  • Meet with sponsor for weekly meeting 1/22/2016

Budget (list amount spent and amount remaining)

• • Spent: $160.87

  • Remaining: $1339.13

  • See budget report for itemized list

Progress on Report and Webpage

• • Completed week 2 requirements
