Machines

1) I imported the the 2D model .DXF file using RDWorks software.

The file was imported into the laser cutting software, and I assigned cut lines as  :

• Laser Mode: Cut

• Speed: 40 mm/s

• Power: 45%
  
  

2) I placed the chosen material (plywood) on the machine bed and adjusted the focus height.

3) I set the laser power and speed according to the material thickness and ran a small test cut to verify settings.

4) I sent the file to the machine using the download command.

5) The laser cutter was started, and I monitored the process to ensure accuracy and safety.

6) After cutting, I removed the parts, cleaned off any residue, and assembled them if necessary.

1) I downloaded my 3D model as an STL file.

2) The file was imported into PrusaSlicer, where I set the printing parameters: 

• Resolution 0.2 mm

• Infill Density: 20%

• Adhesion (Yes)

• Support (No)

3) I selected PLA filament, loaded it into the Prusa printer, and leveled the bed to ensure proper first-layer adhesion.

4) The sliced file was saved as G-code and transferred to the printer.

5) The printing process was monitored, especially during the first few layers, to ensure there were no adhesion or extrusion issues.

6) Once printing was complete, I carefully removed the model from the bed, removed supports, and performed light finishing.

Since this was my first time operating both the CO₂ laser cutting machine and the 3D printer on my own, I was excited to complete the process independently. I relied mainly on the operation manuals for both machines, which provided clear, step-by-step guidance. While I did not actively seek design feedback from others, I did discuss my progress with peers, sharing my approach and exchanging general tips on machine settings. Their encouragement helped boost my confidence, and in turn, I shared small operational details I learned while working through the process.

The skills I learned this week—operating a Prusa 3D printer and an Almalky CO₂ laser cutting machine—will be directly useful in my final project. I now know how to prepare design files for both 2D and 3D fabrication, set the correct machine parameters, and troubleshoot basic issues. This means I can confidently create custom components, prototypes, or decorative elements for my final project without relying entirely on external help.

By combining both tools, I can produce parts that require precision flat cuts with the laser cutter and complex 3D shapes with the printer, giving me more flexibility and creativity in my final design.
