3D Scanning and Printing¶
Goals¶
Group assignment: - Test the design rules for your 3D printer(s) - Document your work on the group work page and reflect on your individual page what you learned about characteristics of your printer(s)
Individual assignment: - Design and 3D print an object (small, few cm3, limited by printer time) that could not be easily made subtractively - 3D scan an object (and optionally print it)
Prior Knowledge¶
I 3D printed several objects in my first engineering class, and CAD is second nature at this point. This should not be especially difficult, although I am somewhat unfamiliar with testing the 3D printer.

Individual Work¶
Plan¶
I would print the golf cart, however, I don’t have all the dimensions scaled. I also find it a bit premature considering I would need to account for microcontroller storage, axle fit, wheel fit, and likely more variables that will emerge in the coming weeks.
I decided that, since I could not create a house with small windows and stairs inside through subtractive manafacturing, I would 3D print one. This house would be for the mini golf course and be extruded the bottom to allow a press fit.
Model¶
Modeling the house was not terribly difficult.
3D Print¶
It occured to me that, frankly, 3D printing this would not be ideal for my golf course. I would rather cut a house without stairs on the inside and paint it as opposed to a random filament color. I cut the press fit extrusion I originally made to attach to the course. Still, I decided that this is a helpful design to understand the layout of the houses I will place.
- Shape
- Sketch 2.5*10 rectangle
- Extrude .1 inches
- Sketch on top
- Offset -.5 inches
- Extrude outline 10 inches
- Sketch on top of outline
- Create rectangle with same dimensions as shape
- Extrude .1 inches
-
Windows
- Sketch on front of shape
- Create vertical construction line at midpoint
- Create symmetrical 2.4*1.2 rectangles towards top
- Create 2*1 rectangles in center of each
- Create symmetrical cross with each rectangle .1 inches wide in center
- Extrude outlines -.3 inches
- Extrude cross -1.4 inches
-
Roof
- Sketch on side of house
- Create line along top
- Extend line by 2 inches on either side
- Create 5 inch vertical line going up from midpoint
- Connect either side with top of line
- Extrude 10 inches across top of house
