Week 1 - 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)

The assignment of this week is fabricate two models of my choice using 3D Printing and Laser Cutting.

Air plane Keychain

For laser cutting I choose to make a single piece keychain with air plan shape and and my name which it is the reason I choose it for.

Keychain / Mobile phone stand

And For 3D printing idea I choose to make a single piece keychain with Tortoise and I choose it because it is simple and has a function which it is a mobile phone stand

Tool Chain

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

Laser cutting

3D printing

Software:

Laser Work V6

I use it because it very simple and i can edit the design and also because it suitable with the machine in lap

Ultimaker Cura

I use it to adjust the parameters before print and to get the g-code file and also because it suitable with the machine in lap

Machine:

Laser Cutting machine

Morn MT3050D CO2 Laser Cutter

Because it is the available

3D Printer

PRUSA i3 MK2

Because it is the available

Materials:

3MM Baltic Birch Plywood

PLA filament

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?

For laser cutting idea I searched in 3axis.com by using keyword (Keychain DXF) then I download the design

For 3D printing idea I searched in Thingiverse.com by using keyword (Keychain) then I download the design

Then import the DXF file into LaserWork software and add a text

Then open SLR file into Ultimake Cura software

Delete the overlap lines

Moving the model left or right away from the center due to the screws in the bed

detect which piece cut or scan with the deferent power and speed

Red: Scan (30 power) (300 speed)
Red: Scan (75 power) (15 speed)

Then save the file with RLD extension

Adjust the parameter which the:

Profile 0.2
Infill 20 %
With support

And select on Slice

Finally the program tell me how many minutes and gram that the design needs

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?

After the software files were finished, I went to the Fab Lab to implement the ideas

For the laser cutting keychain I used the computer of the machine to open my RLD file and download it into the laser cutting machine, then I adjust the focus and test the coordinates and then Run

For the 3D printing keychain or mobile stand I used the SD card of the printer and copy my gcode file in it then adjust the filament color and the temperature and then Run

Then there are the final models

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?

Title of Media

I was Asking about the value of the Cut power and the different values of scan

And the cut power (70 with 15 speed)

Also the scan power (from 25 to 40 in this case)

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?

If you are going to make a medal, make the hole bigger

Final Project

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

I have gained some knowledge that will help me in making the body of the laptop cooler by the laser cutter and the power values, velocities and coordinates

WOW!

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

The coolest thing that I have learned this week is make a useful and simple things by 3D printer

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.
