Weekly Assignments Final Project About me

3D Scanning and Printing

This week, as a Fab Lab, we first started with our group assignment. We tested our four printers' design rules by printing the same design and comparing the outputs. In particular, I arranged the printers and fixed their problems when occured. I also shared my thoughts on the outputs to indicate the differences between them. Then, I documented the whole process.

In addition to contributing to the weekly assignment, I designed and printed my 3D object that could not be made subtractively. I also scanned my face.

3D Printing

My final 3D object consists of a pyramid with a ball inside. I printed it using a Bambu Lab A1 3D printer and the Creality Hyper PLA filament. It looks like the following image.

Final Pyramid

I will first explain the Fusion 360 design process of my pyramid.

  1. I sketched a square with a side of 40 mm.
  2. I then extruded the square to add a height of 40 mm.
  3. Afterward, I tapered the angle by -28 degrees to make it a pyramid from a cube.

  1. Then, I created another pyramid inside of my original pyramid to remove its inside.
Pyramid Second Sketch Pyramid Third Sketch
  1. Afterward, I put a ball inside and alligned its position.
Pyramid Fourth Sketch
  1. I used the offset tool to have a tiny hole at the bottom of the pyramid and to fill out all the remaining area.
Pyramid Fifth Sketch
  1. Using the fillet tool, I rounded off all the edges.

My design was now ready, and I printed it.

First Printed Pyramid

However, I was not satisfied with my pyramid as it was not possible to see inside, and the ball got damaged during the print process. Therefore, I went back to my design.

  1. I first opened a single hole by extruding a circle.
  2. Then, I created a pattern of holes all around one side of the pyramid.

In addition to the new design, I now decided to print the ball next to the pyramid and then stop the printing process. Afterward, I added the ball inside again and let the machine print the whole product.

Second Printed Pyramid

It was almost good enough, but I accidentally moved the plate after pausing the printing process, so the upper side of the pyramid shifted a little. Therefore, I printed for the third time.

Third Printed Pyramid

Scanning

This week, I also scanned my face using an EinStar 3D scanner.

Scan 1

Second, I adjusted some parameters like removing small floating parts.

Scan 2

Then, I drew a plane to remove the part of the image that I didn't want to include.

Scan 3

And it's now ready.

Scan 4

Conclusions

As someone not having much experience in 3D Design, I learned so much this week. For example, I learned about the differences between the subtractive and addittive designs, how to pause the 3D printer and then continue the printing process, and how to make a pattern in Fusion 360. I also learned how to scan an object by scanning my own face.

Note: I didn't include the scan file because it was too large.
