3D Printing

 3D Printing (Additive Manufacturing) = Fighter Jet

For the 3D design, we were supposed to come up with a design that can only be printed through additive manufacturing. In layman terms, can be built up on but not carved.

Thus, to integrate additive manufacturing to my design, I decided to hollow out my plane using the "shell" feature. The design of the cone and the nose of the jet is difficult to carve hollow. This is due to the difference in the surface area within the jet.

For the printing process, Dr Noel who were with me at the time advised that the speed of the printing should be accelerated as initially my design will take up to 1 hr 6 min to print. Thus, I increased the printing speed from 50 mm/s to 70mm/s. This reduces the printing speed to 54 minutes

Since my design has a round base, we need to print the support structures. I decided to use the tree design for support structures as I saw that the tree support uses less materials than the normal support.

Now we print!
