Week 3 - 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)

My assignment's idea is a a geometric shape pen holder.

I do love geometric shape a lot and I will not be bored seeing geometric shapes around me.

So, why not! :D.

Tool Chain

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

I used Fusion 360 to sketch the the pen holder

Ultimaker Cura to slice the shape and Pursa 3d printer to print the pen holder.

For the material I will use PLA+

Please check week 1 for further details

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?

I designed the pen holder by using the Loft option on Fusion 360.

I draw 6 sides polygon and mirrored the shape 2 times.

I used construction option called offset plate to be able to draw on the same axis but with some height between two plates.

I draw another 6 sides polygon with the same dimensions and mirrored it again like step 2.

I finished the sketch and then used loft.

I used the shell option to create a hole with thickness 1mm.

Then I exported the file as .stl and opened it using Ultimaker cura to prepare it for the 3D printing machine.

I used layer height .3 and infill was 20%.

Since the design was fully touching the plate there was no support needed and I checked the adhesion box

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?

I transferred the .gcode file to the machine's SD card, chose the file from SD card using the machine selector and then pressed start.

The pad started to heat up, after reaching the correct heat as I set in the file (215) as it is the recommended temperature for the PLA material machine started to print.

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 did ask for feedback on slack channel as I was not sure of if the holder will stand or fall like the mobile holder (check week 2 journal if you didn't yet :D)

While printing in the lab another colleague was completing his journal and I asked him if he knows anything about sketchfab and how to use it, he said no.

I told him what is it and how to use it with the trick of how to share the design on the site (shared on week 2)

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?

For someone who sketches a 3d object and even use drawing apps for the first time it was very hard for me to remember all the tools and remember what tool I should use to do the thing I want.
I used google search, YouTube and videos from week 3 sessions since I believe in try and error approach to learn.
I managed to finish the sketch after some trial and after deleting and a lot of CTRL Z :D
My design dimensions wasn't the best and while printing I discovered that the pen holder will not fit most of the pens (only thin pens will be okay). This mistake happened as I didn't do my design on cardboard first (lack of experience led to this) but I will learn from this that I need to check dimensions first before sketching.
Another thing to mention I thought that I edited the temperature on Ultimaker Cura to 215 but when the machine started to heat I discovered that the temperature is 200, I checked with Noha (Fab specialist) she showed me how to edit the temperature from the machine and also, told me that the printer saves this settings for first layer only so, after the first layer is printed I need to edit the temperature again but it will be aved for the rest of the printing layers.

Final Project

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

Since this week's objective was knowing how to sketch 3d models from scratch and I learned this following the hard way (check the above question if you didn't yet to know why).

This will help me to design my project with the correct dimensions using Fusion 360 features and sub features I learned in this week.

WOW!

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

The coolest thing this week was the EoW exercise (Lego design) but with the peer learning way.

I was just sketching and my colleagues was instructing me.

This helped me to see another perspectives and way of thinking and we finally managed to design it.

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.
