3D printing !

3D printing, one of the things I was mostr excited about ! Firstly, before we do anything, there are multiple steps before we reach our final product. If you're wondering, this is my final product.

 

To reach this final product, we have to design it in Fusion360 (yayyyy....)

Step 1: Stating parameters

Thickness is for how wide the sections are

Clearance is for how far apart the sections are 

Step 2: Creating the Sketch

Firstly, we create a sketch, on the XZ plane.

Next we create a line, from the origin, and making it 12mm.

Remember to ensure the line is set to construction as we will only be using it as a reference point.

Next, I created a 3 point arc using the given tools under the create tab.

After that, I selected the midpoint constraint and after that

I selected the circle mid point of the arc and used it with the construction line we made earlier

I then used the horizontal/vertical constraint to align the arc with the line as seen below

An this resulted in.....

The arc is now fully aligned with the construction line, this lays the foundation of our product.

Using the sketch dimension tool (D), I selected the arc as well as

 the construction line, and gave it a radius of 20mm

Then, by using the offset tool, I offset the curve in order to make another one,

do not worry about the dimensions just yet as we will have to modify the arc

The T looking symbols are the constraints, and I deleted them, 

causing the arc to not be defined, however 

I later then defined it as the thickness parameter we set earlier as

 it will be easier to change parameterically.

Heres a close up!! 

This is what our current sketch looks like. However, the inner arc is not lined up

with the outer arc, to fix this, we will once again use the horizontal/vertical constraint

Now that they are finally lined up, we can create a line across the top and bottom

 to complete one part of sketch that is needed for the final product that we have

After this, we have to create a few more components until it meets our needs. In this case, 4 more!!

Using the same principles, I used the offset tool to create the arc, however since I have a complete body, I have to turn of the chain selection in order to just select a single arc.

And again, using the same principles, I deleted the contraints in order to set the length as the clearance,

However, as you can see, the arc is not in line with the curve,

 hence we use the horizontal/vertical constraint to solve this issue.

After repeating this step multiple times, I am left with our final sketch, although it looks basic,

it will be close to our final product using just a single tool! Revolve!!!

For the revolve tool, I seleted all 5 planes, as well as selected the axis of it to revolve around the construction line we made, and after this we were left with our final product.... anddddddddddddd

Honestly, it looks really underwhelming, but its whats on the inside that counts right guys? right??

(psa I added the handle after printing my first one, realising, it would perform much better as a fidget toy/keychain with a handle on it, hence why this looks a little different from my final product!)

This is what it looks like in Cura, overall the printing process took 46 minutes to do!!

And here is the hero shot of my amazing product that spins like a gyroscope!

Here is also my stl file, to be included

Reflection!!

If I have learnt anything from this, it is that 3D printing is not as easy as it seems. However, as we practice more and more, we are able to grasp this knowledge better in this area. Our previous lessons has definitely helped me along the way, especially with designing the handphone stand,it has made fusion360 a lot more easy to use as I am more familar with the product. CAD, computer aided design, was the stepping stone, and definitely helped me achieve todays goal. For the nre app, Cura, it was hard to navigate, especially with all the different settings, but this was all resolved with a few minutes of research and just messing around to find the best settings which seemed fit. After this experience, I am definitely more hyped and pumped up for future projects at hand !!
