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?

Design glasses on Fusion360

THE FRONT FACE

After opening software I saved my file with name "princess glasses" and choose "create sketch" to start drawing my design

By using standard dimensions, I made a grid for glasses structure on one side
start drawing Curved lines by using " spline" ( fit point spline ) inside squares to save dimensions

By playing with these lines from green points I get my final sketch

To complete my design, I make it mirror to another side by selecting all objects and select mirror line

I didn't forgot to make holes for screws and nuts 3mm and continue this holes as a design on front face by making another holes bigger on same axis

"splines" had a big challenge with line, it is too hard to make it fully defined

give dimension for all lines and center curve and refer to origin point to make shape fully defined.

using "Coincident" I started to close the shape and make sure that all points close to each others and colored black

To defined spline I choose "fix/unfix" and select all , that made my sketch fully defined and ready to extrude

click on finish sketch, get to 3D work place
finally, I made extrude the shape 2.5m

now, it's ready for export DXF file and prepare it for laser cutting on LaserCAD software

THE SIDE ARMS

I create new component to make separate model
choose "create sketch" to start drawing side arm for glasses
To connect the front face and arms, the arms must have a vertical part, and this part must be parallel to the front face
start drawing Curved lines by using " spline" ( fit point spline )
making hole for screw 3.3 m

give dimension for all lines and center curve and refer to origin point to make shape fully defined.
To defined spline I choose "fix/unfix" and select all

then click on finish sketch, get to 3D work place
made extrude the shape 2.5m

start drawing the arm Curved lines by using " spline" ( fit point spline ) inside squares to save dimensions

by using "Coincident" I started to close the shape and make sure that all points close to each others and colored black

give dimension for all lines and center curve and refer to origin point to make shape fully defined.

To defined spline in sketch I choose "fix/unfix" and select all , that made my sketch fully defined and ready to extrude

click on finish sketch, get to 3D work place
finally, I made extrude the shape 2.5m

To make the design smooth, I made all edges Fillet 1mm

to make 2nd arm, I select "mirror"
choose the object and mirror plane "z"

finally the model ready for export as STL file

select " save as mesh " and choose STL
now, it's ready for export STL file and prepare it for 3D on Ultimaker cura software

After export DXF/STL files from FUSION 360, It's LaserCAD & Ultimaker Cura time to prepare my design for fabrication 💪

2d model

To prepare 2D model I made some steps

Download the design file (dxf)
Open LaserCAD software and import (dxf) file
Start to select lines and coloring it related to color function which related to design :-

black : for cutting
blue : for fast cutting

Put numbers for these colors

black : 40mm/s for speed - 45% for power
blue : 300mm/s for speed - 10% for power

export the file to (AI) format to be prepared for laser cutting

3d model

To prepare 3D model I made some steps

Download the design file (stl)
Open UltiMaker-Cura software and import (stl)
start to adjust model parameter values for:

layer height : using 0.2mm
infill : using 10%
supports : model no need supports
adhesion : no need
scale : no need
orientation : model step on flat side

slice the model to get time and weight for model

time : 14 min
weight : 2g

save the file to desk to (g.code) format to be prepared for 3D printing

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?

My cool glasses " Princess Glasses "

To get the final product there are some steps for implement the design and divided into :-

2d design

I prepared the PLT file on flash memory and connected to the machine’s PC

open software "Laser Work" and import the file
check layers power / speed numbers
open the machine power and download the file with my name "HR"
press on file button and choose the file from screen of machine

put wood sheet on machine and stick it by using supports
Adjust laser nozzle and tie it well

press origin button to make start point for laser then press frame to Determine the cutting area
check laser power by press on pulse

close the machine cover , open Air hood press "start"
laser machine start with scan then speed cut and finally cut

it takes 2.5 minutes and take 14×8 wood

3D model

I prepared the STL file on memory card and connected it to 3D machine

open the machine and leave it to adjust heat of nozzle

change orange filament and put black one

cut the end of filament with pliers 45 degree cutting
choose unload filament then remove orange filament and put white filament
choose load filament and leave it take out old color filament
choose "yes" after it extruding white filament
clean a nozzle by removing extra filament from a nozzle using tweezer
I choose "print from SD" and choose my file

leave the machine preparing bed and nozzle heat and bed balance
after machine get the heat it started to build the model

it takes 27 minutes and take 6 grams PLA

After cutting and printing, it's time to fix parts together with 3M screw and nuts using Screwdriver

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

After printer finish the model, some plastic appeared on the model it wasn't drawn on the model

After show it to fab specialist, he explain to me that is happened because of more heat in the nozzle

He gave me special tools to clean plastic to improve model quality

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

After finishing cutting the shape, I noticed that some parts of the shape didn't cut completely
I tried to disassemble it but it almost broke
I used cutter to cut the incomplete parts
Then I used the special tools to clean edges to make it smooth
I asked specialist about the reason, he told me that may due to the machine needing maintenance by cleaning the lens
I also measured the thickness of the wood and found it to be bigger than 3 mm, as it was 3.13 mm. This could also be the reason for not cutting the wood completely

Final Project

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

The Construction Parts for final project

learning how to design physical parts of project using software like "fusion 360", this software help me to make all design (2D or 3D) in one Workspace and make it too easy to imagine relation between them and simulation the connections and screws
Too easy exporting files for laser cutting or 3d printer software.

WOW!

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