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)

I have searched for some shapes on google and found this shape on the left which I found useful .

I liked it and liked the shape of a half ball that we used in the last hands on . so I wanted to merge the two shapes together.

Tool Chain

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

Ultimaker cure App

3D printer machine

Fusion App

I have used fusion App to design my project, then I have used Ultimaker cure App to put some features and view its timeline before operating the machine. Finally I used 3D printer to print my model through printing I have used orange PLA filament.

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 APP to draw the parts of the design , then I used revolve , hole and extrude options Then I saved the STL file.

Base shape

I draw a square with 50 mm side to be the base of the shape.

ball shape

I draw a circle of 40 R. Then I trimmed it to be a quadrant.

Revolve and extrude

After I drew the base and ball I extruded the base to 10 mm and revolved the quadrant .

3rd skitch

I then made a new skitch on the top of the ball to draw small circles . I draw one circle and used circular pattern to complete the shape.

Using hole option

I used extrude to make the upper shape then used holing to make it empty inside.

Extrude cut

I used extrude cut for the rest circles to cut them inside the ball.

Done!

I have used plastic material and this exciting color.

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?

The shape in Ultimate cure App

After I have saved the STL file of the hole project I then opened the Ultimaker App to set the supports to touching surfaces , layer height to 0.3 ,scale to 49.8 * 49.8 * 55.1 mm and infill to 5 % and gyroid shape. Then I send the gcode file to the 3D machine using SD card.

the first part of my project

After sending the file to the machine I found the black filament but I changed it to orange then started printing.

Making the ball part

Preparing to build the upper part

Making the upper part

We are about to finish :)

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)

When I started to see the model on Ultimaker App I found that the hole shape is shelled and there is no infill :(.

My instructor told me to return to fusion and edit the shell I had made.

I couldn't use shell again because it will cause the same problem so I used "hole" button instead .

Final Project

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

Top view

After the machine has done there were some strings . I used some of the fab-lab tools to remove them.

Side view

I was thinking of making some colors on the base but I didn't like the idea so I left it orange :) .

Actually , the holder can take more than 27 pens and pencils :0

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 saw this shape for the first time I thought I won't be able to do it on fusion but me and my colleague Marwa succeeded making it . :0
