3D Brain Storming Idea

3D Printed Hollow Form Object

This weeks assignment is to create 10 ideas of objects that could be printed on a 3D printer.  A few of the limiting parameters include:

• must be closed polyform
• must be self supporting when printed.  Considerations include:
• no horizontal surfaces other than the top
• attempting to maintain >~35 degree angle of surfaces relative to the horizontal

I chose to render the objects with the "artistic" view setting in Rhino.  In some cases, I also used a different method of display to highlight a specific feature of the object.  I experimented with many of the example techniques demonstrated in class including:

• loft
• rotate
• taper
• twist
• shell
• stretch
• planarsrf
• copy
• revolve
• bend

Object 2

Object 3

For this object, there is some question whether the bottom rung of nodes are self supporting due to the angle at the bottom of the node.  The angle might be less than 35 degrees.

Object 4

Object 5

Some concerns I have with this object are the many points along the surface and the struggle the 3D printer has with sharp points.

Object 10

In rereading the assignment, I think Object 10 might not meet the criteria listed.  I included the object because I think it looks pretty cool and I feel it is a little different from many of the other ideas as it is quite organic.

Overall, I liked the assignment.  I find I start running out of ideas after about 5, and then I really struggle with the last 3.  I was pleasantly surprised by how attractive the top view of the objects often are, especially if the object is twisted.  The symmetry of the image really stands out.
