Blog Entry 4

What's up everybody!!!😎 Today, I will be sharing about my experience in a recent practical I have completed. The egg-drop challenge, Practical 5. In this practical, I have partnered up with one of my best buddies in my class, AMINUR!!!!!!!!!!!!!😊💝

Personally, I would say that this assignment is my favourite assignment I have done so far in Singapore Polytechnic as I had a lot of fun completing it 😍. Unfortunately, beside having fun, I also faced many challenges and obstacles along the way 😖.

At the start of the practical, Aminur and I were very determined and confident to come up with the most complexed design. However, in the end, we had 4 different designs as many of them failed which was very demoralising 😭😭😭.

Anyways, I will begin with showing you guys our final design! "THE BOX"

Yes, you may be wondering, HOW IS THIS A COMPLEXED DESIGN???

Well, after facing many difficulties and failures, Aminur and I decided to setlle for something much simpler that has a higher chance of succeeding.

Despite it being a simple design, Aminur and I are still very proud of it as it turned out very beautiful as you can see in the picture😄, and IT SUCCEEDED THE EGG-DROP CHALLENGE!!!!!!!!!!! WOOHOO!!!

Now, I will be showing you a detailed pictorial guide on the 3D printing workflow.

Converting the Fusion 360 file into a gcode file

1) Please select and click on the "File" option on the top left-hand side of the Fusion 360 design.

2) Click on the "Export" option as shown below.

After that, you should see a tab as shown below:

3) To convert the Fusion 360 file to a STL file, click on the file type and select "STL Files (*.stl)" as shown below. Once STL file has been selected, click on the blue export button.

It is required to wait quite a while for the file to be exported.

Converting the STL file to a gcode file

4) Open up Cura 5.0.0 and click on the printer option list as shown below. Click on "Add printer".

5) Click on "Add a non-networked printer" ==> "Ultimaker B.V" ==> "Ultimaker S3". Once Ultimaker S3 has been selected, click on the blue "Add" button on the bottom left of the screen.

6) Click on the file option on the top left-hand corner of the screen as shown below.

7) Select the files you want to print. Then click on "open".

8) Once you have selected the files you want to print, you can adjust the printing setting as shown below. For our 3D print, we kept the filament thickness to 0.15 but changed the infill to 20% to create a more hollow shell.

9) Click on "Slice".

10) Click on "Preview".

11) Insert the thumb drive for Ultimaker into your laptop. Click on "Save to Removeable Drive" to save it as a gcode file.

12) Insert the thumb drive back into Ultimaker S3.

3D printing workflow

1) Turn on the main power supply.

2) Turn on Ultimaker by flicking the switch behind

3) Load the Filament roller onto the tray which is located below the Ultimaker and ensure the box is showing temperature values on the front.

4) Unlock the filament inserting hole by flicking the knob up and inserting the filament. Once the filament has been inserted into Ultimaker, flick the knob down to secure the filament.

5) Click on the "load" option on the screen to load the filament into the printer.

6) Allow the filament to come out of the print core until it touches the base of the printer. Then use a set of tweezers to cut off the filament.

7) Tap on Confirm once you cut off the excess filanmment which extruded out of the print core.

8) When you are now at the home page, press "Select from USB".

9) From the long list of 3D prints available, select your 3D Print design.

10) Tap on "Start print" to start printing your design.

11) Wait for the print to finish and then click on "Finish Print".

12) Gently remove the base glass plate from the Printer and wash it in the sink. The adhesion between the glass plate and the printed structure should decrease, making it easier to remove our structure.

Embedded Fusion 360 Model

This is our Fusion 360 model of our final Box Design.

 

 

Egg-Drop Test

As you can see in the video, WE SUCCEEDED!!! Our egg DID NOT break and The Box was still intact and undamaged.

Later on in the video, we also proved that the egg we used was raw by cracking the egg.

Print Quality

Lastly, I would like to showcase our final design product. Aminur and I believe that our design's print quality is 10/10. Let's admire it together shall we?

This is a slow-mo video showing how SMOOTH the screwing is. It being smooth indicates that the threading was done well and the print quality is excellent.

These are some picture I have taken of our design, it shows every part of it. We are very proud of it 😘.
