Design for laser cutting click here
Design for 3d printing click here
Our assignment for Week 1 involves fabricating a project using laser cutting and 3D printing techniques. I chose to create a wall portrait with an intricate design, cut using a laser cutter, and an earrings, printed using a 3D printer.
My inspiration came from various online sources, like: Thingiverse, Pinterest, 3axis and free dxf.

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. RDCAM: For calibrate parameters (speed-power) and prepare file for laser cutting.
2. Cura: For preparing STL file and configuring 3d printing settings like scale, infill and quality, ensuring the printing time remained under 90 minutes.
Machines:
1. Laser Cutter: For cutting wall portrait design.
2. 3D Printer: For printing the earrings.
Materials:
1. 3mm plywood: For laser-cut.
2. PLA filament: For 3D-printer.

Laser cutting design Process:
1. Selected DXF file for laser cutting from online repositories.
2. Edited the design using laserwork software (RDCAM).
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 250 power 30
speed cut: speed 300 power 10
3. Laser-cut the wall portrait design.
3D printing design Process:
1. Selected STL file for 3D printing.
2. Edited the parameters of design using Cura software.
In this step, I started preparing the file by configuring 3d printing settings like scale, infill and quality, ensuring the printing time remained under 90 minutes.
The parameters for process:
Infill: 10%
Quality: 0.15 mm - fine
Scale: 200%
with adhesion
weight: 5gm
3. 3D-printed the earrings.

Laser cutting fabrication
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.
3d printing fabrication
3D Printer Operation:
1. Prepared and sliced the design file using Cura software.
2. Collaborated with the lab specialist to adjust the machine's temperature settings to 215°C.
3. Transferred the file to the memory card and inserted it into the 3D printer.
4. Selected the file using the navigation knob and confirmed with "Select."
5. Initiated printing and monitored the first layer for accurate deposition.

I recommend selecting a file with fewer grams, as I initially chose a 22g file. However, the machines specialist advised opting for a smaller file to save grams for upcoming tasks, prompting a last-minute change. Last-minute changes were chaotic! 😂🙆🏻♀️

During the laser cutting process, I encountered the following challenges:
1. Interference between the wooden parts “which fixed the sheet” and the nozzle prevented it from cutting the corner correctly (see attached photo). I asked the machines specialized in this part, and she suggested that I cut it with a caliper instead of redoing it because it is a small part.
2. Increasing laser power to 30 overheated the scanned part, I didn't love its dark color. The machines specialist made me understand that reduce power for better results.
During 3d printing process:
1. I had the temperature set at 200, so the machines specialist told me to set it to 215.

This week, I learned how to use machines and their tricks, prepare files and set parameters for cutting and printing.
I encountered some problems and learned from them, so I think I will use them effectively in my final project.
WOW!
