Week 2# - Journal

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)

1. Ideation✨

this week assignment is making a real cool glasses, so i went searching Pinterest as usual and i took my inspo out of the crescent lady painting.

pulse it relates to Selene moon goddess in Greek mythology.

SOOO i technically made a moon glasses.🌙🕶️

Tool Chain⚒️:

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

AlMalky ML149 laser cutter

for fabricating 2d parts

3mm ply wood

as it will be our martial to fabricate on using laser cutter.

MK2 3D Printer

for fabricating 3d parts

Ultimaker cura

to prepare STL. file to be 3D printed.

laser work

to prepare DXF. file to be cut using aser cutter.

fusion 360

for designing process

Red PLA. filament.

for fabricating 3d parts

3m screws and nuts

to assemble all parts together

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?

Design Process:🌟

2D part

which is will be laser cut out of plywood

-the only huge problem here is that you get all your sketch fully defined.

-but here is my desgin process:

-I started by the center circle that was 54mm -which is the standard dimension of a glasses lens,

-then i offset 2mm to be the frame of the lens

-then mirrored it to make the other lens, and added the bridge between them,

-and added a tangent constrain between it and the lenses

now i added the m3 screw hole which is 3mm.

-finally finished sketch added appearance and this was my final result.

-and i mirrored it to the other side

+ i added more circles to make the shape in the left side which i will engrave on later

How to Mirror a Body in Fusion 360 Tutorial

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

Development/Implementation Process⚒️:

Design/Preparation Process:🌟

Here comes the fabrication part 🌟

2D Laser cut part

1.After finishing our sketch in fusion 360

extrude it 3mm, then select the body face, and by using our DXF. for laser bulge-in, add your machine kurf mine was -0.1

it will save a DXF file .

2. open it to laser work add your parameters

mine was 50 power for cutting| 30 speed

-Now put the ply wood sheet on laser cutter bed.

-then after adjusting the focus hit start.

VID_20240125025806.mp4

and let the magic happen. 🌟

3D printed part

1- select the body and right click it then choose save as mesh

2- choose stl. for format then check send to 3d printing utility fusion will open cura

3- But this will send only one body you will need to save the other body as stl. the open it with the first one in cura.

3- start adjusting your parameters:

1- resultion: 0.3mm

2- Infill:

I adjusted infill to 10% .

with gyroid pattern - just because i like it-.

3- support:

no supports because there is no over hanging .

finally slice and save your G-code and add time and filament grams to it

the first layers of printing

-which i got after copy\ paste its g-code from my laptop to SD card

-then choose print from SD card from 3d printer menu

-finally choose your file

The final result

which had an over extrusion and stringing problem.

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)

Overcoming Challenges🌟

-Mirroring Bodies in fusion360 was the very first challenge in designing process

and here is its tutorial:

How to Mirror a Body in Fusion 360 Tutorial

I had a few problems while fabricating actually

1st problem

stringing and over extrusion:

there was stringing and over extrusion due to some problems in the machine it self

so I started by cutting string totally, and thats how it looked after cutting strings.

then i started sanding it till it looked like the surface is all clear

then I sprayed it to restore its color and for better final look

2nd problem

How to engrave a drawing in Laser cut.

I wanted the drawing to be engraved on the final product like this.

so i imported the image to test it but that was the result which is not what was i attempting to.

Sooo i dogged into laser work and by trying some options that was my second test.

And this was my final result.

And here's how to engrave a painting an image using laser work✨

1- Import the image you want to engrave.

2- you can see in the preview it looks like fully un defined

3-back to home choose BTM

4-choose Dither and dot graphic then apply to view

5-this will be your view

6- And this will be youy previw

3rd problem

the glasses was too weak.

while assembling the parts i needed to sand the laser cut part like 1mm, and while doing this it got broken so i refabricated it.

I locked the scale at first

then i selected the circles one by one, and changed its scale from 100% to 80%, and it turned from this:

to this.

Every part file:

the glasses face [dxf.]

1st handel [STL.]

2nd handel[STL]

the two handle G-code [gcode]

the crescent lady drawing [gbj.]
