Week 2 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

Create a Cool Glasses for my personal use my glasses design must be a mixed design

which Design the front frame by using Fusion 360 to be fabricated using a Laser Cutter and the side arms Design by using Fusion 360 to be fabricated using a 3D Printer

i decided to Fabricate thug life glasses, i have inspired by it it's very unique sunglass so i take the same idea to make normal glass and then i may turn it to sunglasses again.

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

Fusion 360 is a cloud-based 3D modeling, CAD, CAM, CAE, and PCB software platform for professional product design and manufacturing. It's the tool of choice to get your students career-ready.

Fusion 360

ultimaker cura

this program is very professional it allows you to fully control on your model like infill, adhesion, resolution and show the time and weight required for finial product

LaserWorkV6

to be honest it's not professional program but it's totally free and it's good enough by using it i can make some changes like color, cut ,scan ,speed cut and scale

prusa i3 MK3

i print by using PLA materials

El Malky ML149 CO2 Laser Cutter

i cut 3mm wood plate thickness

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

part 1 (front frame)

2D work i start with draw just half of glass and then i use mirror to draw the same shape in the opposite side with vertical axis

then by using trim i delete the useless lines and i design two hole to fix arms with front frame i make the hole with diameter 3mm because i'll use M3 screw and nut.

after i have finished drawing i make extrude and appearance for shape just to see finial product in 3d

part 2 (two arms)

i build the arm from the base of holder which has hole in the center for easy fix with front frame

this base was 10 mm * 10 mm because the the hole is 3 mm and the nut will take about 5.5 mm so just remain 2mm* 10 mm rectangle,

note that the hole diameter will increase to 3.30 for tolerance of 3d printed part.

i extrude the rectangle 2*10 but i feel like it is very week for this critical point so i use loft to increase volume of the arm special at this corner so i start from half of circle loft to main rectangle 2*10 and i extrude it again to 100 mm

after filet

after i've finshed the arm and its ready i make the second arm with mirror

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

part 1

i export my front frame as .dxf for laser cutting

import dxf file to laser cutting i adjust the cutting setting power and speed and download it on machine

part 2

i export the arm to stl file two arms each individual

then i collect them on Cura together and choosing the right position to avid support which will increase weight and time required and give the finial product bad surface finish so i tried to avoid using it

the 3d printed has taken 54 minutes to print 8 gm of two weight

after i've assembled the parts i realized that the surface finish was not good because the resolution was not good enough (0,2) and the plastic arm may hart your ear

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

make the arc in the arm it was kind of hard to understand where should i draw center point and what is the angle of this arc to make it comfortable,

my own glass helped me at this point so i measure the angle and the center point of arc from it

it was 300 mm to left from arc at height of 100 mm.

after i draw arc start from center of main rectangle i use sweep to make thickness of Irregular lines like this arc.

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

the finial shape was amazing for me it was very cool and look like thung live sunglasses

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

it will be the power of design and important so when you are ready to design something, you have to be very accurate because every single point will reflect on you product for example :

in my design i draw front frame but once i comparing it with my real glasses i figure out that it will be hard and very sharp on nose, so i make this squire as curved one.

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.

after i've finished fabrication of my glasses, i want to make it like thung life sunglasses so i use dxf file to cutter plotter machine cameo3 to cut black vinyl in the same size and i stick ti on front frame
