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)

This week assignment is about design a single 3D Object using Fusion 360 and fabricate it using 3D Printing.

I care about practice and know the 3D tools because it will help me in the final project.

The picture in the left is the inspiration model in this week. I thinks its perfect because it have a separate part for each similar objects.

The right picture is from my favorite movie i want to put it as a sticker as it have the same seem .

Tool Chain

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

Designing process

Software: Fusion360

It have a nice futures for 3D modeling which will help me in the assignment

Fusion360

For 3D printing

Software: Cura Ultimaker (For slicing process to Know the require time and material for printing the model
Machine: Prusa MK2 3D Printer
Material: PLA

Prusa MK2 3D Printer

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 Steps

Base Sketch

1- Start drawing the base

select the center rectangle and make its center the origin of the selected plane 8*15 cm
I want to make it in shape of pot so i draw a triangle in the front of the shape
To make the part fully defined, i put the dimensions of each line with a defined one

2- Split it into small sections

I want to make a part for sticky notes because i use it usually
i search for its size and find it will be 7.5*7.5 cm

sticky note

sticky notes

fully defined sketch

The remining part i will split it into 3 parts

1- For small objects size (I give it 3 cm)

2-For medium size (I give it also 3 cm)

3-For pencils and large object size (I give it 4 cm)

3- Make 3D model

I have extrude each part individually
shelled this extruded part (2mm shell)
Repeat this process

Extruded-shelled part

4-Filte the edges

Making the sharp edges with filet it very important for make any model looks good

So I make a 3 mm filet in the main edges

5- Text

Make a new sketch and From Create>> Text

And I write my name

Then I make it extrude cut as shown

6-DXF

I was very cool and helpful to get a ready design and use it.

I get a ready DXF file from the internet and use it in my mobile holder.

From insert >> insert DXF >> choose the file you want and put it in the desired face

Extrude cut for the DXF design

7-Apperance

change the appearance of the part was one of the main requirements

As shown in this picture from Modify >> choose Appearance >> from library choose >> plastic

Final output model

8-final Model

1- small size part was extruded by 1cm

2-medium size was extruded by 2cm

3-large object size was extruded by 4cm

4- sticky nots part was extruded by 2cm

9- Export

To make a 3D printed object we have to out an STL file from Fusion 360

From File>>Export >>STL

10-Cura

To open the STL file in cura

From file>> open >>select the STL file

The object i design with the wanted scale i find that it will take about 4hr

11-Scale Down

I scale the size down to fit the requirements not more than 90 min and 30 gram

My pen holder will take 89 min and 22 gram while printing

12-Export G-code

Save G-code For the next step (Fabrication process ) to put it in the 3D printer

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 preview of the slicing

Put the G-code in a flash memory(renaming it with the grams, mins and color.) and put it in the machine.
I started with clean the bed,
chose the file and begin to print.
heat it to unload the filament
Change Filament color to be satiable for the astronaut .
The printed the pen holder was 22grams in Green color and 89 mins.

Final output model

The printed 3D model

The 3D model After the machine had finished

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)

sketching phase

while splitting process i want to trim the un-needed lines from the sketch .

so i trimmed 2 of the rectangle lines which by default made the sketch undefined and get a warning message

I solve this problem simply by making these 2 lines as a construction lines

un-defined sketch

Wrong Shell (section analysis )

2-3D Phase

I want to extrude the whole sketch in one time and then shell each part

but when i select the face that i want to shell it shell the whole body because there are no borders

i find making these borders in the sketch will be so hard .

So i solve this problem by extrude each part individually then shelled this extruded part (2mm shell) then repeat this process

Final Project

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

Robot Arm

In the Robot arm

Knowing and practicing how to deal with 3d modeling using software as Fusion 360 will help me to make this part from the final project easily .

As I'm now know how to make a 3D parts and how to assembly this parts together to make a final part which in this case will be robot arm.

WOW!

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

LEGO Minifigure

As a in class activity we model, assemble, and animate the parts of a LEGO Minifigure.

Model the Head and Torso of the LEGO Minifigure.
Change the appearance of the parts to match the real ones.
make the head rotate 360 degree

The most important thing that i will never forget that i have to find the shortest way to reach the desired goal or target

as while we make the Torso we were had 2 ways which were:

Extrude: which is the ease way and it could archive the objective
Loft: it was the longest way to make this part and it would make some problem during the progress of the following parts
