Week 01
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 was to get and prepare open-source design files for digital fabrication using 3D printer and a Laser Cutter.
oreo cookies
At the beginning I wanted to 3d print an oreo cookie for my fiance Abdulrahman as he's the oreo cookies' line leader, but the model was a bit complicated, so I decided to give him an oreo coaster indeed.
climbing Thin
A cool friend for my laptop screen, i had once before called Semsem but it had broken, so i decided to make another friend to talk with.
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
Softwares
Machines
Materials
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?
1- 2D Laser Cutting:
1.searching for the open -source file
Firstly, I searched for a dxf file for Oreo cookie, i couldn't find a free one. Then I found DWG verion, I transformed it into DXF using AutoCAD software.
2. file preperation
After exporting the DXF from AutoCAD, I imported the file to RDWorks. After that i adjusted the layers' speed, colors, and power based on the machine guideline.
3.file exporting
Finally, I checked the preview and time for fabrication and then, I exported a .rd file compatible with the Malky ML1930 laser Cutter. Now the file is ready for fabrication.
2- 3d printing:
1.searching for the open -source file
Firstly, I searched for a .stl file and choosed something then i downloaded it
2. file preperation
After that, i opened the file on Ultimaker Cura, adjusted the scale, infill% and the printing profile. I tested the slice mode. The file didn't need support and i checked the adhesion box for a brim.
3.file exporting
At the End, I exported a .gcode file compatible with the 3D Printer: PRUSA i3 MK2 after choosing the filament color at the lab. Now the file is ready for fabrication.
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?
1- 2D Laser Cutting fabrication process:
Start the machine.
Makes ure the chiller is open.
Copied .rd file from computer to the laser cutter using a flash memory.
Insert plywood sheet in the machine.
Close the door
Adjust the origin and then try the framing to make sure the design fits the plywood.
Start cutting.
2- 3d printing fabrication process:
Make sure the printing settings are adjusted with eng. Passant, the lab specialist
Printing temperature: 215c.
Build plate temperature 60c.
Speed 60 mm/s
Export and copy.gcode file from computer to the laser cutter using a memory card.
Insert the PLA filament with desired color.
Start the machine.
Start printing.
Overcoming Challenges
What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)
The oreo coaster was finished without the R letter, so we keep the plywood at its location and regenerate the machine to engrave the R.
Firstly, we oriented the R on the same location and deleted the rest of printed items, but the program oriented the origin above the R not in the same place it started with the first time, therefore it wouldn't be printed on its same place. So we tried another way, we kept the rest of items at the file but with output value (No) and only the R with (Yes) and this idea had worked.
After the laser cutter finished the R letter its line weight was a bit darker even we used the same settings (speed, power,layer color,.. ) as the first trial.
The reason for this issue most probably was that we used (delete overlap) command, so the R polyline became not closed even though it was seen on the file before printing.

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
Using the machines (3d printer and laser cutter) on my own for the first time, changing the 3d printer filament and making memories on this day with Esraa my lovely instructor, Passant the lab specialist and Alaa, my team-mate

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.
Hands-on activity was SuperMakers Plan a Party! We as a G3-G4 team, decided to take furniture to Farnasha planet and pamper them.
