I'm in love with keychains so I decided to search for a cute one for my laser cut assignment as my inspiration to put it with my other keychains with no keys ;')
I searched using: 3 axis
As a nervous person, I needed something to calm me down so this was my inspiration in search and I looked for it using: thingiverse
It took me a lot of search, though, to find my cute Godzilla you're going to see
for 3D printing:
software: ultimaker cura to prepare the files and save it as g code so the machine understands it
machine: Prusa i3 mk3 which is used in ODC
material: PLA
for Laser cutting:
software: RDWorks to prepare the files for laser cutting and set the parameters of cut and speed
machine: EL MALKY ML1390 laser cutter
material: 3mm Plywood
laser cut:
I used RDWorks to get my Godzilla ready
for speed cut and making a line without cutting I set the power to 60 but increased the speed to 300
for cut the power was 60 and the speed was 10
for scan I selected all the closed shapes to engrave it and set the power to 15 and speed to 100

3D:
first of all I selected Prusa i3 mk3 machine, the filament: pla, layer height: 0.15 mm because I needed it in high resolution, Infill: 40% then I downed it to 20% and it was fine
I rescaled the model to 52% to fit the time
It didn't need support but it might've needed adhesion which I haven't added and realised during fabrication when I found the part off the bed in some points
after slicing it said it would take 1 h 13 mins and 6 g of filament.
Finally I clicked save to disk and saved it in g code to get it ready to be copied to prusa to be fabricated

but this one is better and works great ;) : gear bearing
tracking the design frame
laser cutting Godzilla which took 41 secs
finishing the print
after a lot of work, it moves. Yeah, it doesn't spin as expected but it moves =D
I had a challenge using RDWorks as it was my first time using it and dealing with laser cutting machines and software.
the scan output was NO :( and in the preview the scan didn't work fine. I changed the speed to 100 and power to 15 then I also realised that the blinking eye wasn't a closed shape so I changed it to speed cut and it worked great. The scan output became YES ;)
Preparing dxf file using RDWorks
The other problem was the tolerance I didn't know about then which made me have to work on separating the parts after fabrication and it didn't spin as it should. So, next time I need to ask for the tolerance of the machine which differs from one to another. Or I could pick a simpler part =').
I could prepare the files of my final project better now for the fabrication. It would be easier to deal with the machines.
the coolest thing was dealing with EL MALKY and seeing your project being fabricated.
