156B Week 6

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

• • Electronic components functioned simultaneously

  • Able to extrude PLA

  • Motor Driver needs to be replaced with one that can handle more current

  • Spool mounts are nearing completion

Accomplishments from Previous Week

• • Base Plate

    • Spool mounts machined, mounting holes created and tapped (Nicholas)

    • Electronic mount created in autocad and will be laser cut (Anny)

  • Extruder Tip

    • Machined half of extruder mount from aluminum (Kevin)

  • Electronics 

    • Finished Arduino protoboard (Armando)

    • Heater and motor work simultaneously (Armando)

  • First successful test of pushing PLA through extruder tip using heating element (Armando)

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

• • Finalize and assemble all components together for working prototype (all members)

  • Start testing with the KUKA

    • Get familiar with milling software (Armando)

    • Ensure baseplate fits onto the mount and all components are secure (Nicholas, Anny)

    • Ensure extruder tip is stable on milling head, integrate tool into quick change rack (Kevin)
