Week 2- Journal

Task's idea:

I always wanted to have one of those cool beach glasses, so the first thing that came to my mind when we were told about the assignment was:" why don't you just make one? " so let's see how I made them.

I drew a free hand sketch with the adequate proportions for human head using my sunglasses

Here it is... the free hand sketch I made.

check out the next steps to see how I will make it.

Tools:

the software systems I used were :

I used AutoDesk fusion 360 to design the glasses parts

I used LaserWorksV6 software to prepare my design before laser cutting

I used Ultimaker cura software to prepare my design before 3D printing

The materials I used were:

Generic PLA Filament

3mm plywood

Screws and nuts

The devices I used were:

Prusa i3 mk2 3D printer

Elmalki laser cutter

Screw driver

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?

Open Autodesk Fusion360 and click save

Then give your file a name "Cool Glasses"

Create sketch then choose a plane to draw your sketch in.

Select Spline to draw your desired outline , then Fix it

Draw line then Mirror your heart shaped sketch over that plane, then Fix it

Select 3-Point arc to draw the bridge between the two hearts

Now save your file as dxf and give it a name

Open the file Glasses Frame using LaserWorks as shown in the picture

Set the color of the design and change the parameter of this color using this next schedule

Now it's time to save the file as to be ready for laser cutting.

The files are now ready for laser cutting

dxf file

.rld file

ai file

Now let's get to the glasses arms;

create sketch and draw the outline

Create sketch on the prependicular plane then draw this shape.

then finish sketch.

Select Extrude and choose 3mm

Fillet the edges 1 mm to give a rounder and softer look.

You could change the appearance and give it the desired color and look to visualize the final product.

Now the design is ready let's save it as .stl form

From the left bar select the body of the glasses arms you want t save and click on Save As Mesh

Choose the desired parameters and click ok

then choose where you can save it on your device

Open the stl. files using cura software to edit the print settings

From the top right toolbar adjust the parameters to:

Resolution = 0.2 mm
Infill = 20%
Support to touching buildplate
set the bed temperature to 60C & nozzle to 215C

Slice the design

It will take 39 minutes to print and 6 grams of PLA material

Now it's time to save the file as gcode to be ready for 3D printing

the file name has to be like this:

name_ color_resolutuin_whight_time

Dina Glasses_ Red_0.2_6gm_ 39min

The files are now ready for 3D printing:

Right arm stl file

Left arm stl file

gcode file

Development 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?

Laser cutting:

Open laser work software, import your file and make sure of your parameters " power and speed " for each line

Press the download button, from the machine, pressed file, choose the file, set the origin point then press start

After 22 seconds, it was done✨

3D printing:

Choose print from the printer panel and from media choose the file, then press OK.

Bed and nozzle temperatures are set to 60, and 215 C

Title of Media

After 39 minutes, my 3D print was done

Uh oh there seems to be a problem

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)

I faced two challenges, let's see how i fixed them:🤔

The first problem was that the arm part to be screwed got broken

Its because the design of this part was faulty. its thickness was too small that it broke

Seems like we need to adjust the design

Here we go

I adjusted the original sketch to these parameters.

Extrude cut this part to make space for the nut to rest

Section analysis to make sure it is of the appropriate thickness.

Here we go there's our adjusted final design

Save it as stl and continue the printing as explained above.

After slicing, It should take 47minutes and 5 grams to be printed

The refabrication process

Here we go , the glasses arms are done.

The second problem was that the sketch was all consisted of splines so it couldn't be fully defined

I fixed it by editing the sketch using CoralDraw software with the help of the Fab Lab specialist and got to successfully cut it using laser.

The glasses frame is cut successfully.

M3 screws and nuts are installed successfully.

The glasses are done.🥳
