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)

This week's assignment was Abooout...

Creating and fabricating a Cool Glasses, making the main frame with laser cutting, and the side part with 3d Printer, then connecting them with M3.

I started the task by googling the diminutions and getting reference for my awesome cool glasses, and I found this nice blueprint:

because I adore plants, I wanted to make some sort of organic shape like that, I started drawing on top of the reference to see my ideas.

My idea is to make it a leaf like shape, then there is another leaf in the middle.

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?

This was my first attempt to do it, horrific, I couldn't make it defined haha XD

annnnd yaaay, my 2nd attempt was like that, I used the point spline tool almost in all the shape to create it. I was able to make it fully defined then I mirrored the other part.

The challenge was to make the shape I want with the LEAST possible points to make it easy to define.

I added a 3mm circle for the m3 nut.

Then, here is the model extruded, I selected the outer shell of the glasses and then pressed extrude Icon, extruded it for 3mm.

I made sure I didn't extrude the screw place.

I selected the faces and pressed extrude as a new body to extrude.

For the sides,I started by making sure of the dimensions from my reference I mentioned earlier, side was 160 mm. I wanted some organic shape as plants, this was my first attempt.. horrible XD

then I remembered I can use the project tool.

so I used it to project from the body for the glasses to make the side holder.

2nd attempt was so much better I was able to get the shape I want.

More over, every sketches was fully defined in fusions.

then I used sweep to make the arm shape

Tool Chain

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

Softwares

fusion 360

Fusion is the main 3D/2D design software used. It's amazing and accurate in creating very specific and true dimensional models for fabrication!

LaserWork

LaserWork is used to prepare files for the laser cutting machine. It’s a straightforward program where we import the outline or vector we want to cut and specify a few settings:

- Cut: Defines the areas to be cut out and removed from the wood sheet.

- Speedcut: Used when creating an outline.

- Scan: Applied to achieve a burning effect or engraving on the wood.

Ultimaker Cura

I used Cura to prepare the STL file for printing. It lets me adjust everything about how my print will turn out, like the resolution, infill, support, adhesion, and all the other settings that affect the print quality.

Physical tools I used:

Malky ML149

3m wood sheets

PRUSA i3 MK2

PLA Filament (1.75mm)

Laserwork:

in Laserworks, I imported the file then I made 2 layers. cut, and scan, and adjusted the values according to the technical specifications of the machine. the speed and power.

I selected the parts I want to cut and engrave or make and outline according to the values.

I placed the shape at the right corner to be ready to be imported to the machine.

Cura:

I prepared it and sliced it using Cura, I imported the STL file, checked the model. it was straight forward and easy.

I modified the resolution to be .3mm and added adhesion and modified the infill to be 60%

I also made the supports to be close to the surfase only, there was no need for it.

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?

Laser cutting

I used the laser cutting machine during this week to make the main frame for the glasses. I I prepared the file on laser work on my laptop.

Then I put the file on flash drive and moved it to the machine pc, inverted, and put the starting point( the green point) and downloaded the file to the machine.

I turned on the machine, turned on the ventilation fan, then I loaded the file, modified the starting point and tested the cutting zone.

I added the 3mm wood sheet and fixed it using wooden clips, and started cutting.

3D Printing

After I prepared the file, and sliced it, I changed the plate temperature in cura, according to the lab directions.

then I moved the file to the sd card to import it into the machine.

before that I had to unload the filment, and changed the color to the black, then I loaded another color using the unload feature in PRUSA.

I selected the file annnnnd paaw.. started printing!

I made sure that the filament wheel is not stuck during the print, and also I renamed the file to include the grams and printing time so that we be able to trouble shoot as the lab specialist told me.

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?

I got stuck defining the spline curve, it was horrible process! I didn't understand at all that I need to define the point itself, then the distance between the two handles, and the angle between them.

At the end of the middle week session. we had a conversation about it.

Also I forgot that I can use offset tool to make the outer body of the glasses, Hala helped me thanks to her ;)

It was just as the picture, but I used offset to make the outer body.

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?

There was a problem in the 3d printer, I had to readjust the bed heating to over come it, so many errrrorrrs.. the printer was missing up the filament and every time the print fails! so I increased the bed heat from 60 to 65.

I also had to enable adhesion inside cura to increase the outer space of supports printing, so the body sticks more. before it it wasn't sticking.

Final Project

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

It will help me fabricate and create the desired shape for my project.

By learning the modeling techniques inside fusion and making accurate measurement.. It will help me a lot.

WOW!

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

When I first wore my Glasses I made... It was super coool feeling when I create something I can wear! Yaaaaaaaaaaay <3

Weekly Digest
