Software Used:

• I used Fusion 360 to design both the front frame and the side arms of the glasses. It allowed me to create precise, customized 3D models.
  
  

Machines Used:

• Laser Cutter – for fabricating the front frame. I chose this machine because it offers clean, accurate cuts, which are perfect for flat parts with sharp edges like the zigzag design.
  
  

• 3D Printer – for fabricating the side arms. This allowed for more dimensional and ergonomic shaping, which is ideal for fitting comfortably around the ears.
  
  

Why These Tools:

•  Fusion 360 allowed me to create precise and creative 3D models.
  
  

• RDWorks was necessary to convert my front frame design for laser cutting.
  
  

• The Laser Cutter was perfect for creating sharp edges and clean cuts for the front frame.
  
  

• The 3D Printer was ideal for building the side arms with more volume and detail.

For this assignment, 

• I used Thingiverse to browse and download a 3D model in .STL format, 

• Prepared for printing using Ultimaker Cura.
  For the laser cutting part.

• I used 3axis.co to find a 2D model in .DXF format and prepared it using RDWorksV8.

• The machines I used were a 3D printer for the white kitten medal and a laser cutter for the space-themed wooden wall art.

For my assignment,

•  I used PLA filament to 3D print the white kitten medal and MDF wood for the space themed wall art using laser cutting. 

After preparing the files,

• I moved on to the manufacturing stage.

 For the 3D printed kitten medal,

• I transferred the G-code from Ultimaker Cura to the 3D printer, loaded PLA filament, clean the bed and started the print.

•  The printer followed the layer-by-layer instructions to build the model.

• it took 30 min and 

For the laser-cut space wall art,

• I used the RDWorksV8 file and sent it to the laser cutter.

• I placed the MDF wood sheet on the machine bed.

•  I fixed the wood sheet first ,focused the laser.

• Checked on all the process and started the cutting process.

• The laser precisely followed the design to cut out the shapes.

• Both machines were essential in turning my digital designs into physical objects with accuracy and detail.

For preparation for laser cutting :

• I adjusted the design settings before cutting. 

• Scale:
  X=100mm, Y=100mm

• cut(black):
  - Speed : 40   -Power:45

• Speed Cut (blue):
  -Speed : 40     -Power:25

• scanning (red):
  - Speed : 300     - Power:20

• the process took 4 min .
  
  

For preparation for 3D :

• After uploading the .STL file into Cura,

• I adjusted the design settings before printing

The final parameters :

• Scale: 120% up-scale

• Infill: 20%

• Support: i Used Touching built plate for Face 

• Adhesion: to prevent warping.

• Layer Height: 0.2

• the process took 25 minutes and 5g for the printing.

• Yes, I asked for feedback from the physical lab assistant, Mariem, to make sure all my steps were correct and didn’t need any editing or reprocessing. 

• She reviewed my work and confirmed that everything was good, and I really appreciated her support and guidance.

• My peers saw my designs and gave me compliments on both the 3D printed kitten medal and the laser-cut space wall art.

•  Although they didn’t suggest changes, their positive feedback was encouraging and motivating. 

• I also shared my process with them, which helped some of them better understand how to use the tools and prepare their own files.

• I got stuck during the 3D printing of the cat model about 15 minutes into the print, it failed and got messed up. 

• I paused and, with help, started researching the possible reasons.

•  After checking,
  - we found out that I had accidentally disabled the adhesion bottom layer after Ive made  in Ultimaker Cura, which caused the model to lose grip and fall during printing.

• Once I reactivated the adhesion setting and double-checked all the print settings, the model printed successfully.

•  This experience taught me how important it is to review every setting carefully before starting the print.

• A tip for others: 

-Always make sure and check for all your steps carefully before you're starting the the printing .

• This week’s experience taught me how to properly prepare files, use 3D printing and laser cutting tools, adjust settings for better results  and fix issues.

• I’ll apply these skills to make my final project more accurate, creative, and successful.

Aside from the main assignment,

•  I tried to create an extra wall art design just for myself bigger and with more details, to hang in my room. 

• I prepared everything, saved the file to a flash drive, selected the right wooden sheet, and set all the machine settings.

•  But when I asked the technical lab about cutting it, they told me it would cost 300 EGP or more , which I found too expensive, so I decided not to cut it. Still, I enjoyed the process of preparing a personal project.
