Week 2 - Journal

I love the idea of make products to turn it real, our assignment this week was make a cool glasses. So I was think at first on some of my friends love cats & I think what if I make to them glasses there is cats on the frontframe to ware it as a sign to their love of cats. At least they can Ware it at places of Cats lovers meeting.

But unfournuitly, I find my self stack to make some things more art and organic than calculation  design. So I change my Idea to what if we make a glasses for students at there graduated Carmoney to ware it with graduated cap & Robe.

Due I am at Cairo University, I make it for Cairo University. Also due to my love me & all engineers to go to MIT, I was add his name on my glasses to be from cairo university to MIT.

• Ultimaker Cura for slicing the STL file 

• Prusa i3 Mk3 machine for printing 

• PLA filament for printing

• RDworks for preparing the file to be laser cut.

• Plywood sheet to execute the frame design

• Fusion 360 to Design the frontframe and arms of glasses.

This time doing some research on glasses in terms of proportions, dimensions and styles. I found this website  and some others, that had very clear information on each aspect of eye glasses design like frame size, lens size, frame styles,... etc. I took a screenshot of the frame style closest to the one I want to achieve.

After slicing  the temple arms on Cura, I went to check the machine and the specialist asked me to scrap the plastic leftovers from the bed and clean it using alcohol. I did that and placed the bed again in place. Next, I loaded the PLA filament (dark violet) to the machine. This time I remembered what I did the week before and did not require assistance. I transferred my file to the SD card while the machine nozzle and bed were heating. Afterwards, I inserted the SD card and started the printing process. After the temple arms were printed, I easily removed them as there were no supports or adhesion in the 3D printing process. Nevertheless, I had to use clippers to remove some excess plastic. 

I think the best thing happen this time is be aware with bolts hole and how it will hard to remove support from it, so I ask my fab specialist how to except it from supports. 

Then I headed to the laser machine and exhaust to turn them on. After checking that my lines were correct, the speeds and powers were accurate, and ran a simulation that showed no overlapping lines, I download the file onto the machine's computer. I placed my plywood sheet onto the machine's bed and made sure it was well secured. On the machine's screen, I selected my file, defined the point of origin, ensured that the frame was in a covering an appropriate area on the sheet, I closed the lid and started the process.  

1. Defining sketch: It was very hard defined all the sketch, I was set and start to define every line then go to the last one until I make it, finally fully defined sketches.

2. Text on laser cut: After I cut the front frame on laser cutting machine, I discover the text was so weak, It will be better if it was more bold or just scan on the square background.

3. Bolts hole: I am happy to ask my fab specialist and take considerations of except holes for bolts from supports.

--but despite of this i find it is more hard to the bold throw             the hole I think i will make it large next time with                                 0.1mm.
