This week's assignment was preparing the files needed to make a 3D printed figure and a laser cut part.
For the 3D printed part, I decided to print something that I really love (Sonic's Old logo), this logo from the classic old Sega games always brings back happy memories, both game and the show were incredible.😄
The file itself can be found on thingiverse :(https://www.thingiverse.com/thing:545589)
For the laser-cut part, I decided that it can also be a some kind of logo or symbol, So Yin-Yang was i the first thing to come to mind since it resembles many things all together.

Since the file in the library was a CDR file, it was first converted to DXF.
then it was imported in RDworks
Made sure that the dimesnsions are as wanted.
Moved the whole sketch to the top right corner, keeping a distance of 2.5 mm between the edges and the borders of the sketching area.
then the areas to be engraved were specified with a single outer circle to have the cut order.
As for the 3d-printed part, it was much easier procedure
Dragged and dropped the file in Cura.
Modified the settings as follows:
Orientation: wide base faced down
Resolution: fine (0.15)mm
Infill: 20%
no supports or brim were needed

For Sonic's logo:
I had to adjust some settings in cura itself before printing. (setting the temperature to 215 and fan speed to 20)
Changed the Filament color to a colour I like.
Generated the new G-code with the new settings and upload it on the SD card.
After inserting the SD card into the printer, waited for the filament and the plate to heat up and carefully watched to make sure first layer is done right.
After the printer finished, the printed part was removed and that's how it looked due to some issues regarding layer height and infill.
Logo before finishing
For the Laser cut part things, went smoother:
Uploaded the file on the pc connected to the Malky Design machine.
Had to set the cut mode to speed 40 and power 45 while scan mode as default (speed 300 and power 35).
After making sure everything is good in the software, File was downloaded into the machine.
Adjusted my origin point and checked the frame then pressed START.
After the part was cut, I sprayed it white and black.

fallen layers
fallen layers
To decrease time as much as possible, Infill was set to be 20% while keeping the layer height fine which caused small multiple layers to form on a weak infill, causing it to fail and fall in few spots.
this can be easily prevented in the future by using stronger infills

Things I learnt today will help when the time comes to print the final project's 3Dprinted parts, setting the suitable conditions to prevent such failures, also if any part needed multiple engravings, for each side, a new origin should be set.
WOW!
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

Well... Something that was WOW for me is just dealing with the laser cutting machine and the 3Dprinter alone (of coarse with supervision in lab but on my own), the experience itself and getting things done that quick was not foreseen.

This tiny T-rex which is barely 2 cm was one the week's tasks.
as to reduce to time as much as possible we had to scale it down from 6 cm to almost 2cm, resulting in a cute little thing we called Baby T-rex or "puppy"😂
it had infill of 20% and coarse height, while the supports were on touching buildplate placement mode.
Baby T-rex 😂
