Week 2 - 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.

the main challenge was in the 3D design to commit to the required limit of fabrication time and save more of the polymer weight for upcoming tasks, which was at the same time a challenge that was about to hinder what  I needed which is full real scale for both arms also I wished for better quality with the proper inner filling design density and design, eventually I managed to accomplish all of the above with a net weight of 8 grams and fabrication time of 43 minutes for both arms !

Update: I faced a huge failure in the fabrication process as the base plane was the one that had my initials with thin extrudes on and also with fillet on the edges which created an error with the 3D printer.

Solution: remove initials and cancel the fillet in the base.

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!
