Week 04: 3D Printing and Scanning¶

This week I worked on defining my final project idea and started to getting used to the documentation process.

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) Group Website

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)

↪ 3D Scanning¶

↝ Scanning objects¶

I had an issue with my phone, so I teamed up with Zubaida Aldoseri to get the work done.

How did we scan?¶

Using Scaniverse we captured the objects above, using the steps below.

Open the application and tap the plus icon. Select the Mesh option and choose the appropriate size for the object.
Record a video of the object from all angles. Afterward, crop the image as needed and export it as an .stl file.

↝ Scanning a Human Body¶

I scanned myself using Skanect. Skanect analyzes the mesh and removes any parts that are smaller than a percentage of the biggest model part. The smaller the percentage, the smaller this filter becomes, removing smaller parts. This is useful when removing random or floating artifacts.

How did I scan myself?¶

I opened the software and selected the path where the file would be saved.
Using the software, I recorded a scan of myself independently.
After recording, I waited 8-10 seconds for the upload to complete.
I adjusted the settings, reducing the face count to 3000.
Next, I filled any holes in the model.

While it’s possible to colorize the character, I wasn’t too fond of the result, so I skipped it.

↪ 3D Printing¶

We used two printers Creality 3D and Ultimaker BV.

Target Audience	Professionals, industrial use	Hobbyists, makers, and small projects

Survey Corps Logo¶

For my first 3D printing test, I printed the Survey Corps logo, which I downloaded from Thingiverse.

The Real Logo
This logo represents the Survey Corps from Attack on Titan, an organization dedicated to protecting humanity from titans beyond the walls (no spoilers).
