3D scanning and printing (Feb 24)

Assignments

* test the design rules for your printer(s) (group project)
* design and 3D print an object (small, few cm) that could not be made subtractively
* 3D scan an object (and optionally print it) (extra credit: make your own scanner)

Applications

  • Fusion360

    Step1

    Print out

    Machine
    Machine is AFINIA. I used first time.
    Data was send from PC to AFINIA.

    Design rule

    This printer can be made 15x15x15cm (XxYxZ)

    Fist printing

    I used existing data from thingiverse.
    3D Printer Tolerance Test
    AFINI could not make small holes in left side.
    Some characters were not created on wall.
    When it was make bottom base. One corner was ditorted.

    Second step

    Made small cube form 7rings

    Data:test_ball.stl

    The diameter of cube is 40mm. Shape of ring diameter is 4mm. When it was printed, Unnecessary thread has been generated. It is need to consider when you create a very small thing

    Third step

    Print of diagonal shape

    Data:test_object.stl

    I tried to print that diagonal shape without supports. The part of acute angle in upper side was collapsed. The part of acute angle in lower side was created the support in automation.

    Step2

    3D scan

    Machine
    Machine is SENSE.
    I isntalled original software for SENSE to my pc.
    I scaned my mouse. But mouse is too small for SENSE.
    SENSE could not scan it.
    I selected chair. see below pictures.
    SENSE can scaned it.

    Data:Scaned_chair.stl


    This scaning machine can not scan small size.
    Belows are tested items.
  • Mouse
  • Arduino
  • Cup(Yunomi) : It is difficult recognize, because omnidirectional 360° same shape.
