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)

The assignment of this week is printing 3d pen holder after designing it in Fusion 360. I searched on google for more ideas and this shape inspired me a lot so I decided to make like it.

Tool Chain

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

Software

Fusion 360

for designing the shape

Software

Ultimaker Cura

for preparing the printed file and slicing

Material

PLA Filament

for using in the machine

Machine

PRUSA i3 MK2

for printing the pen holder as 3D

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 used Fusion 360 to create my design.

1- Creating an offset plane at the same distance away from the front plane.

2- Sketch on this offset plane.

3- Draw a circle centered on the origin with R=20.

4- Draw a line that represents the diameter of the circle and put it on the origin point.

5- Begin a solid revolve and select the top side then adjust the angle to 180 degrees to get a hemisphere or bubble.

6- Then click modify and make copy command to create another hemisphere that is diagonally below the current one.

7- Make a circular pattern of these 2 bodies, and adjust the quantity to be 12.

8- Then make rectangular pattern to complete the shape, select Quantity = 4 and Distance = 53.

9- Create a sketch on the top and draw a circle to close the shape.

10- Then combine all the parts.

And finally I exported the file as STL extension from Fusion 360.

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?

After implementing the design in Fusion 360, I used Ultimaker Cura software to import my design then I adjusted the settings of the design to achieve the requirements. I made the infill = 15, quality = 0.3 and without support. It took 1:30 h in printing.

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)

The requirements in this week was not to exceed the time or weight limit (30 grams or up to 90 minutes).

After designing the pen holder in Fusion 360, I imported the file to Cura (Software) to know the time and the weight, but I surprised that the shape was very big so much so that it was out of frame of the printer box, So the software didn't know to calculate the weight and the time.

so I decreased the dimensions (X,Y,Z) as shown in the second picture, It was good to be in the frame of the box, but the time was very long :(

The Solution

So, I decided to decrease the dimensions again, quality, annd the support.

Quality = 0.3

Infill density = 15

Support = touching Buildplate

Final Project

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

I will use the features that I learned in Fusion as (Revolve, Sweep, Loft, etc...) in designing my final project to be more creative as like I designed the pens holders & vases.

WOW!

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

I designed the head and torso of the LEGO Minifigure with my colleague Ahmed Atef.

I designed the ball and the base of Fidget Object with my colleague Ahmed Osama. Also, I learned how to model the Hook and Hook Connector parts and change the joints movement with all direction.

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.

I made a lot of vases and pen holders using Fusion 360 with several 3D design features (Revolve, Sweep, and Loft, etc...). All designs are different and special.
