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 was about preparing design files and fabricating models using 3D Printing and Laser Cutting.

For 3D printing:

I used https://www.thingiverse.com/ to pick a 3D model, i love the bulldogs so i searched about a design of one on thingiverse.

Here's a link of my inspiration:

For laser cutting:

I used https://3axis.co/dxf-files/ to search about some ideas.

I decided to make a key chain so, i searched about a DXF keychain file.

Here's a link of my inspiration:

Tool Chain

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

For 3D printing:

To create my design I used ultimaker_cura, to get the G_code so i can start printing the design,

then i used the 3D printing Prusa i3 MK2 machine to create the design, and the design was made of PLA .

For laser cutting:

Machine used in laser cutting was the laser cutter

the software i used was the laser works to make the file in the rld format to start cutting it on the machine .

Material: 3mm sheet of wood

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 3D printing:

I downloaded the design file from thingivers in STL form

then i opened the file in the ultimaker_cura application to convert it into a G-code so i can be able to slice it and prepare it for printing.

i changed the scales to save more time and material.

-editing the print sitting by choosing PLA with infill 10% and 0.2 of profile defaults

-i used support and adhesion for my design.

-slicing the design

- taking 48 mins, and 7g of PLA.

-At the end I saved the file as Gcode

For laser cutting :

-First thing i started to import the dxf file to the laser works software , then i started to select the parts that will be cut.

-I started to edit the settings of the file : output, speed 30 and power65 of the laser cutting .

-I dragged the file at the corner of the work area at the origin , to make use of the rest of the sheet and save more of the material.

-last thing is to save the file as .rld

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?

For 3D printing:

at first, from the menu, we should preheat the machine to change the filament and the material we used was PLA until the machine was ready ,then we should upload the G-code in the memory card of the machine, then we choose our design.

For laser cutting :

open the laser cutter

insert the file onto the machine computer(Download from laser works software ) and adjust it then press on start button

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 asked my instructor about what will happened if we rotate the design and if this will save more time and material and he suggest not to rotate it as we didn't have to rotate.

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 planned to print another 3D printing 'vase' but i had encountered flaws in the design ,the printer make unarranged additive layers so i figured out that there was flaws in the design.

then i decided to print another design.

Final Project

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

i can use it to make the parts of my final project as i learnt how to deal with the 3D printing Prusa i3 MK2 machine to slice the design parts.

I learnt also how can i use laser works to define the cutting and engraving parts

WOW!

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

learning how to use the 3D printer was the coolest thing.

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.

the party i had planned with my group was super cool especially our superpowers.
