Module 4

Step 1: Evaluation

Cube and Sphere: This design was successful as we were able to print both a cube and sphere in the same design where the end result was two disconnected objects. The base that the 3D printed was easy to disconnect and did not effect either of the objects. By printing two objects in a single design, it saves time despite the fact that you have to disconnect the objects at the end of the printing process.

Alphabet: This test was unsuccessful as we were trying to get the letters to touch each other. The 3D printer was able to print in a higher resolution than TinkerCAD allows you to go in. We placed the letters .1mm apart which is the smallest increment that TinkerCAD allows and the 3D printer was still able to print the letters with a space in between. From this design we have discovered that the 3D printer is very exact and will print objects .1mm apart successfully.

Freestanding rectangles on base: This test was also unsuccessful. We wanted to create a freestanding rectangle that under its own weight would be weak and structurally unstable. The material and format in which the 3D printer used created a structure that even the thinest rectangle not only was able to stand under its own weight but also could support human interference in the shape of trying to bend it.

(As our group's freestanding rectangles were not printed, this is a photo of another group's printed freestanding rectangles.)

Step 2: Evaluation Rubric

Criteria	Does not meet (0 points)	Meets (1 point)	Exceeds (2 points)
Ease of print	Design is not streamlined causing a lot of extra material to be used or extra time to print.	Design uses some excess material that could be done without.	Design is streamline and prints perfectly to the point that no excess is material is used
Stability	Can't withstand its own weight.	While it can withstand its own weight, any force causes structure to become unstable.	Withstand its own weight, even when force is applied on the object.
Dimension	Too large/small for proper function	Dimension is not perfect but gadget can work somewhat	Perfect dimensions allowing gadget to work efficiently
Functionality	End result does not perform intended function	End result does not perform function perfectly or is able to perform function with the help of outside factors.	End result does perform intended function perfectly.
