Module 3

STEP 1: TinkerCAD explorations

We measured in mm as it meant we wouldn't be working in numbers less than 1. The original cube design on TinkerCAD was 12.7mm cubed and the sphere had a diameter of 6.35mm. The cube given to us was 25.4mm cubed. We therefore doubled the length of all the sides and doubled the dimensions of the sphere to keep it proportional to the change of the cube.

How was it created?

When we ungrouped the design we found that it was made by a solid cubed that had been hollowed out by 3 rectangular 'holes' that go from one side of the cube to the other. The sphere has been made by using the basic shapes and then simply dragging it into the centre of the cube.

This design was started by taking a cylinder and putting it on a rectangular base. Then the cylinder was hollowed out to project the sound. A groove is added onto the cylinder to hold the phone. Then it was angled to project the sound upward and outwards. Then shapes are added to add to make it look more like a cannon.  

STEP 2: Limitations

Cube and sphere

We chose to test this design because it allows us to see whether we can print two free moving separate objects in the same print by connecting them with a thin connection piece that is broken off after the object is printed. Thus potentially allowing two objects to be printed in the same print. If this is something that is able to be done, the time that it takes to print 2 objects can be significantly reduced by printing them in a single design.

Alphabet

We chose to use this design to see how close together we can print two objects without them fusing together or the needle not being able to print anymore. Some designs that aim to leave space between 2 objects may work in theory with TinkerCAD, but limitations of the printing process could mean the printed design is actually connected. Knowing the distance between two objects in which the 3D printer can still function and leave space between the two objects is very important for the design process.

We chose this design to test how thin a 3D printer could print while still being able to hold itself up. Contrary to the alphabet test, knowing how thin the printer can print an object is also important. Not only does this show how accurate it can be with details, knowing the thinnest possible line helps us understand how strong/weak the overall design can be. Thus resulting in being able to print something that will not snap under its own weight.

STEP 5: Show and Tell

Bottle Opener- This object functions as it is supposed to and has a very different design to that of a traditional opener.

Shin Guard- This object didn't seem to have the right dimensions to fit a shin. We are unsure at this point if it is still in the design phase however we think that new measurements will be needed to make it fit right.

Phone charger cable- This object looks like it would be very useful. If the dimensions are correct, we can see this being a success in giving the iPhone cord structural support.

C-clamp- This design is made of 3 seperate objects that will need to be put together. The idea is very interesting as the opening is different to that of a traditional c-clamp. If it is successful we believe this will be a very effective way of storing keys.
