Scout Regiment emblem
A dart
For this week’s assignment, I decided to print a badge inspired by the "Attack on Titan" anime, specifically the Scout Regiment emblem. I used 3D printer for scout regiment emblem and laser cutting for the dart. I care about this idea because I’m a big fan of the anime and wanted to create something personal and meaningful for memories. It’s also a good way to combine design, fandom, and fabrication. I was inspired by fan-made merch and images from the anime like this one and it pushed me to make a one for me while i can do everything impossible arround the maker diploma.

Laser Cutting Design/preparation process
For this project, I used the website 3axis.com to find a nice design (A dart). I downloaded it in DXF format, and also tried other formats to see which one worked best for laser cutting.
Then, I opened the file in RDWorks. I resized the design and made a few changes in the middle part to fit what I needed. I moved the design closer to the top-left corner to match the machine's starting point.
I used different colors to tell the machine what to do:
Blue for cutting
I used 40 for speed in order to cut precisely with a good power 45 and it passed well because it was recommended to use for 3mm plywood sheet in the fab lab
Red for speedcut
for 3mm ply sheet it is recommended to use 300 for speed for engraving fastly witn stylish the lines arround the circles and 12 for power.
I made sure the cutting happens at the end to keep the shape clean. After that, I saved the file in rld format, which the laser machine can read.
3D printing Design/preparation process
First, I used Thingiverse to find an open-source design of the Scout Regiment emblem from Attack on Titan. After downloading the design in STL format, I opened it in Cura, selected the machine, and adjusted the size and print settings to fit my target.
I referred to the recommended settings provided by the design owner, but made a few adjustments. I also set the layer height to 2 mm to reduce printing time while keeping a decent finish.
Infill 20%, Resolution 0.2mm, with no support and no placement touching buildplate
After slicing, I checked the estimated print time and filament usage in grams. I saved the final file in G-code format, using a naming convention that includes the design name, print time, and filament weight.
One small challenge I faced was accidentally changing the scale while zooming in. In the end, I'm satisfied with the final size—though it fits exactly, I would have preferred a small margin from the max size for a more comfortable print

I recommended one of my colleagues to reduce the infil so her 3D print would come out better especially the parts that hold the paper in her project and it came out as it previewed. the papers are maintened well .

During the laser cutting process, I faced two issues. First, the scale of the dart design (DXF file) was too small, and I had to adjust the scale four times until it looked correct on the machine. Then, when I tried to start cutting, the machine showed the output as “No” instead of “Yes”, which was confusing. But even with that, the machine started cutting successfully.
Print failed
As for the 3D printer, it didn’t print on the first attempt, which really shocked me. I immediately called the Fab Lab specialist, and they simply advised me to restart the print. I tried again, and the second attempt worked perfectly.
From these experiences, I learned that small issues like wrong scale or misleading messages can cause confusion, but they’re often easy to fix. It's important to stay calm, ask for help when needed, and double-check your design settings before starting. Others can avoid these mistakes by testing scale early and not ignoring unusual machine responses.

Smart robot delivery
In short my final project consist an assistant robot that helps or assists a person in his current situaton what he needs to have (tools, water, charger etc...) so I intend to use 3D print to built the frame of my robot, laser cut machine for the body parts and electronics components to make it work.
WOW!

What truly schoked me this week and don't let me forget is how we use simple cardboard for building prototypes in no time, no needed machines, Creating from almost nothing to something real meaninful was the coolest experience that i will never let this principe pass away from me.
