From the article: Why do cats' eyes glow in the dark?

Task Description:
Design a cool personal glasses to be digitally fabricated using laser cutting or 3D Printing.
Ideation: Design is very subjective and my definition of cool design is creating a surprise element that can not be discovered by just looking at the design but you have to experience it.
With the above being mentioned, I wanted to create "cool" glasses that can glow in the dark like cats' eyes. I wanted to keep it minimalistic with a very simple frame, and the focus will be on the rounded lenses which will be covered by a "glow in the dark" spray.

Which software/machines/materials did you use in the assignment? Why?
Design: Fusion 360 was the hero of this week; I started by practicing the video tutorials before designing the frame (2d) that was intended to be fabricated on the laser-cutting machine, then did the two arms and extruded them into a 3d model to be fabricated on 3d printer.
Preparing for fabrication: Laserworks software was used to prepare the file for laser-cutting with color code and chosen operation. Cura was the software used to create a g-code file for the arm before 3d printing.
Post-processing: in terms of materials this week, besides using PLA filaments for 3d printing and wooden sheets for laser cutting, I used glow-in-the-dark spray to have this cat-eye-looking effect. I also added two screws to attach the two arms to the frame at the end.

3D Design for the arm-legs:
From the side view and by starting a new sketch, the arm was created and extruded. I had a challenge extruding the line in the beginning but I figured out at the end that the curves were not closed.
With the appearance option, I was able to apply some materials to my design before fabrication to see if it is visually appealing or not.
It was really important to offset the diameter of the screw in the 3D printed part by 0.2 mm in comparison to the screw diameter, 3 mm, so it fits inside the whole after 3d printing (clearance).

2.5 Design for the frame:
In the beginning, had to check the standard dimensions that should be considered when designing glasses.
The shape of the lenses was intended to be simple to mimic the cat eyes' shape in the dark. Once I was done with the first half and I was satisfied with the design features and dimensions, I mirrored the other half.
In this stage was the file ready for laser-cutting? the answer is no because simply there is not enough room for adjustments on Laserworks so I had to imagine what operation (cut, speed cut, and engrave) I will apply on each part of the design and make sure that this part is separately defined on Fusion before I exported the file into DXF.
It was so challenging to define the sketch as there was a tiny little line next to the frame lenses that I could not detect in the beginning but finally everything was defined. The frame was extruded to add materials/appearance to it.

Laser-cutting the frame:
It was really helpful that all the lines were defined separately before I import the file to Laserworks.
The first operation (in red) was cutting the 3 mm plywood with 50 power and 45 speed. I had to slice the design into three layers and glue them together in order to have room to insert the lenses after spraying them.
The second operation (in black) was scanning with speed 250 and power 12.
The two arms were exported as an STL file and I used Cura to slice them into a g-code file. They only took 33 mins to be fabricated and they consumed four grams of the filament spool. Despite the fact that the two parts are identical, the quality was different, I was advised by the lab technician either to re-print it again or to try to cut the extra threads (pasta) with a fine cutter. The only supports that were added are the ones touching the bed as I wanted to preserve the surface quality as much as I can.

In order to get the effect of a rounded circle that glows in the dark, I had to add an extra layer of material to be able to spray it separately and then inserted it inside the frame later. The only option was 3 mm and I needed to create tolerance between parts in order to make it fits so I ended up sanding its surface so it can fit in between.

If I would like to keep a good surface quality, I have to follow one of the two approaches:
1. Spend time doing post-processing including sanding and coating the model before covering the material with spray to hide the damage.
2. Design the angles from the beginning so they do not need support to be fabricated, or split the models into separate parts and assemble them after the printing process using smart/ hidden connections.

During Saturday's session, we had a team activity to create a bookmark using the 2d and 3d knowledge we gained from the video tutorials.
We were a group of four; two were designing the part for laser-cutting and two were designing the part for 3d printing. It was funny how we kept changing the dimensions of the face till the end as there were some design features that only exist in the 3d printed part as an extension of the wooden part on laser cut.
The two parts came nicely at the end and surprisingly the dimensions were correct and that was a happy moment for all of us!!
