The assignment idea this week is to get familiar with the whole process of digital fabrication with 3d printer and laser cutter machine. first, models are downloaded, then prepared to machining, and lastly fabricated using machines. it was a great excitement for the first hands-on experience using digital fabrication machines, I looked for online models for inspiration, but I decided to start with simple models to focus on the procedure.

Which software/machines/materials did you use in the assignment? Why?
Which software/machines/materials did you use in the assignment? Why?
For Laser cutter machine (Morn MT3050D CO2 Laser Cutter): material is PLY wood sheets (3mm thickness) and the software is LaserWork, to prepare the model for machining.
For 3d printing (Prusa i3 mk2): Material is PLA, and software is Ultimaker Cura.

After downloading the 3D file from thingiverse, I used Cura to slice it and resize it to the proper size. Also profile is set at 0.2 to produce a relatively smooth surface finish. Infill is set to 20% to produce light model with some supporting structure.

LaserWork is used for the 2D file from Dxfdownloads that was downloaded from thingiverse to identify which parts to be cut and which to be sliced and the power and speed for each.

For cutting (black color) speed is set to 25.0 mm/s and power to 65% of the maximum power. For slicing (red color) speed is set to 300.0 mm/s and power to 25% of the maximum power.

For Laser cutting: after the file is prepared and revised, PLY wood sheet is placed and the clearance between the nozzle and the sheet is checked, also I checked that the range of motion for the file is within the sheet placement, then fabrication started.

For 3d Printing: after preparing the file and slicing it properly, file copied to SD card then inserted in the machine to start fabrication.

For the 3D printed file, the dog was standing vertically like the first photo, but the instructor suggested that I make it lying on its side to avoid any supporting structure to make it easier for the machine.
after discussion I was convinced and decided to go for it on its side, and everything went good.
Overcoming Challenges
Overcoming Challenges
When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

For this task there was a small mistake I made that the was causing the Laser machine not to start, I didn't notice there was the website name in the file and I didn't delete it or specify a cutting speed for it, so the instructor notified me and after deleting it everything went fine, so it is very important to review the file accurately before machining it.

How can you use the skills and knowledge that you've acquired this week in your final project?
Laser cutting and 3D printing will be the main techniques used to manufacture the main structure of the final project.
The final project is an automated system to water plants as shown below.
where Laser cutter machine will be used to manufacture the main chasis of the project from PLY wood.
3D printer will be used to print the enclosure of the control unit.

Of course the whole experience of using digital fabrication machines won't be forgotten and I hope it could be a life-time skill that I don't stop using when I need it even in everyday life application.
