Week 3 - Journal

Using the 3D Printer

1. I begin by creating or importing my 3D model into slicing software.

2. I adjust the print settings, like layer height, infill density, and support structures if needed.

3. I export the sliced file (G-code) to the printer’s SD card or send it directly if it’s connected.

4. I prepare the printer by loading the correct filament and ensuring the bed is clean and leveled.

5. I start the print and watch the first few layers to confirm proper adhesion and alignment.

6. Once the print is complete, I remove it carefully and clean up the print bed.

7. If needed, I perform any post-processing like sanding, painting, or assembling parts.

Using the Laser Cutter

1. I start by preparing my design in a vector-based software, making sure the file is in the correct format for the laser cutter.

2. I set the correct cutting or engraving parameters based on the material I’m using (like power, speed, and frequency).

3. I place the material securely on the laser cutter bed and focus the laser head to the correct height.

I send the file to the laser cutter and run a quick test cut to ensure everything is aligned properly.

4. Once everything is set, I start the full job and monitor the process for safety.

5. After the machine finishes, I remove the cut pieces, clean any residue, and check for quality.

To bring light into the darkness they say? 

exactly! that's what we did by designing this lantern to insert the flashlight in, can't deny here that our main star was the rectangular pattern which is obviously the reason behind the easiness and beauty of geometrics.

Surprisingly despite completing full joined components 3D design using Fusion 360, I faced a chaotic situation in the process of the laser cut fabrication, which is the extra lines drawn in the next figure and I couldn't determine the reason behind those lines as in the original sketch the design was fine...

But thanks to my instructor eng. Hazem He helped me to investigate the cause of this failure which was a false intersection between the curves on the top and the rectangular itself.

After editing the sketch to make the curves tangent, problem was solved! :)

Now I know more about real sizes for machines and how to create a virtual estimation for them on software tools such as Laser cut and Cura, not to mention to take in consideration the limitations of producution in terms of how much materials are consumed and production time.

Checking out the precise work of the printing machines was mind blowing as it was my first practical experience which made me start to consider myself as areal maker!
