Homunculus

For 3D printing, we were asked to create a teaching prop that was 3D printed using Fusion 360.

Design time: ~8 hrs | CAD Software: Fusion 360

Print Software: Cura |Printer: Ultimaker 2|Print time: ~4 hrs

Instructions:

  1. Find an image you wish to convert into 3D print and upload image into Fusion 360 as a canvas, scale to size and move to central axis of plane, then click ok. To see image as background while you are working with is change opacity of canvas to ~10%, this will make it easier to see lines you are tracing.
  2. In Model mode use sketch tool using spline lines to outline each lobe.
  3. In sculpt mode extrude from sketch change to appropriate # of faces needed.

 

4. In the sculpt mode modify and fill hole of each side of the lobe. I used the reduced star mode and had to fix some of the T lines before going back to the model environment.

 

 

 

 

 

 

5. In Model mode click create new sketch for each new body part on Homunculus. ( I used a combination of spline lines, concave lines and straight lines.

6. Extrude each body part separately changing the width of the body part on each side.

7. Continue to repeat steps 5 & 6 to create the body parts for the other side of the homunculus.
