Week 01#: Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? Please include images or links to sources of inspiration.

This week, my assignment idea focuses on designing 3D-printed and laser-cut files. Harry Potter has always been one of my favorite series. Ever since I first watched it as a child, I felt like I grew up alongside Harry, experiencing each part of the story year after year. It created a special bond, almost as if Harry became part of my own family in a magical world. This project feels like an exciting way to bring a piece of that magic into reality.

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

2D laser cut

First, prepare the file and import it into the workspace
Delete unwanted construction lines.
move it towards the origin.
Adjust the parameter settings so that the black lines indicate the cut.
speed:40 power:45
Adjust green lines to no output so the laser doesn't affect it because there is no need to do it.

3D printed file

First, prepare the file and import it into the workspace
reduce the size to 3 cm so it takes less time to print
Adjust the parameters to suit the print so we don't need adhesion; it has a strong, flat surface enough.
profile: 0.2 mm, infill: 10%
and adjust the support to:
type: normal
placement: Everywhere
support pattern: lines
time: 56 min
size: 8 grams

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

WLCOME BESTIES 🥳

TOOLS AND MACHINES

As soon as I got to the lab, I prepared the STL file on my laptop and transferred it to an SD card for the 3D printer. I powered up the Prusa i3 MK2 and set it to start heating the bed. After that, I switched the PLA filament to red. The entire printing process took about 1 hour and 10 minutes. Removing the tree support was a bit tricky, and I accidentally lost the wand and broke the toy's glasses in the process. I think next time I’ll set the layer height to 0.15mm to avoid this issue.

While waiting for the 3D printer to finish, I worked on preparing the DXF file of the cat. I turned on the laser machine, activated the vacuum cleaner, secured the wood in place, and checked the height between the wood and the laser nozzle. Assembling the cat was a bit tricky since it was small, and the wood's thickness didn’t quite match that size. I ended up sanding it down to make it fit, and voilà! It came together perfectly.

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

I was concerned about the 3D print potentially failing, so I asked Farida for her opinion. She suggested switching the support type from lines to trees, explaining that it would be the ideal choice. Tree supports are easier to remove and less likely to damage the print, making them perfect for this project.

Later, while at the lab struggling to assemble the cat parts, the specialist suggested using sandpaper to smooth the edges and make the pieces fit together more easily.

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

I always rely on the instructors for guidance, and in my case, it's usually Farida. She's incredibly friendly, patient, and genuinely helpful.

I also did some research to learn more about Cura since it offers many advanced settings, and I wanted to understand them better to ensure smoother printing.

Also, I focused on the shell thickness, as it wasn’t clearly explained in the tutorial videos.

If someone were to print my design, I think they should increase the layer height to 0.15mm or more. The design includes a lot of small parts that aren’t well supported, so making it stronger would help. This way, the support structure wouldn’t cause issues when being removed.

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

Learning to operate the machines freely and successfully will surely help me with my final project. as well as familiarity with the software, will help to streamline and improve the process. and avoid issues in the future projects.

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

our second green session was amazing, as i learned alot about sustainability and solar cells making

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.

They divided us into small groups for a group activity, where I took on the role of advisor. I guided Aya in creating the laser file and directed Mark in working on the 3D file. It was a really encouraging experience because we got to operate the machines independently. It felt like a hands-on training session, and we successfully completed this week’s assignment perfectly.

best team ever 🤟
