Size guide

Our assignment for Week 2 involves designing pen holder and fabricating it using laser cutting and 3D printing techniques for brackets. I chose to design my own pen holder using my favorite touches.

My inspiration and size guide came from designs on google.

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

Here's a list of software, machines, and materials I used for the assignment:

Software:

1. Fusion 360: for designing the parts of glasses.

2. RDCAM: For calibrate parameters (speed-power) and prepare file for laser cutting.

Machines:

1. Laser Cutter: For cutting 2d design.

Materials:

1. 3mm plywood: For laser-cut.

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?

Laser cutting preparation Process:

In this step, I started blackening the parts I want to cut, blue is for parts I want to draw, and red for the parts I want to engrave. then I started calibrating parameters (speed-power) for this properties.

The parameters for process:

cut: speed 40 power 45

engrave: speed 300 power 25

speed cut: speed 300 power 10

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?

Laser Cutter Operation:

1. Adjusted speed and power parameters.

2. Activated the machine using the 'green switch'.

3. Transferred my file from the PC to machine via USB cable (by clicking "dawnload" in laserwork software).

4. Fixed the plywood sheet in machine.

5. Selected the file by pressing "file" in screen and adjusted nozzle positioning using arrow keys.

6. Set the origin point (where the nozzle would start cutting) by pressing 'origin'.

7. Verified alignment using 'Frame'.

8. Activated vacuum and initiated cutting by pressing 'start'.

9. Monitored progress until completion

10. Finally, turned off the machine and ejected parts.

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 made the compartment without tabs in sides, that made it not stable enough.

I advise that you always finalize your work early and bring all files and your laptop during the printing and cutting. If there's an issue with the design, you can go back and ask the instructors about it. ✌🏼

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 faced an issue during cutting because the files wouldn't open in either AI or PLT formats. I had to go back, retrieve the lab, and resend them in DXF format. This experience taught me to always have all the files and labs with me to avoid similar delays in the future.

Additionally, the Fab Specialist suggested that I review my measurements to avoid repeating the process again. I did so and found them to be accurate.

2. I also faced some issues during designing the comparator because of taps, I could not use project, so I design it manually.

3. I also had some challenges during assembly it in the full pen holder.

4. during the cutting, the power rate was high, that causes wood burning. when I repeated the process, I edited the power rating and made it lower.

Final Project

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

This week, I learned how to design and assembly parts in Fusion 360 using jointing techniques like T-slots / tabs /brackets or brackets with captive nut. I encountered some problems and learned from them, so I think I will use them effectively in my final project.

WOW!

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

Besides the hands-on learning experience, I thoroughly enjoyed the journey, absorbing valuable tricks and gaining insight into Fusion 360 software. The team spirit with fellow colleagues – sharing advice, capturing moments, laughter, and encouragement – created unforgettable memories.

Weekly Digest

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.

I felt proud and thoroughly enjoyed designing these innovative 3D models!! 😍
