Assignment 3: Ferrari Front Bumper Relief Details



Tutorial - Ferrari Front Bumper

Step 1: Mapping out the Shape from 3D Model or File


Using the high resolution 3D Print (see Assignment 2) and direct measurements from the buck (using the middle piece as a centrepoint) map out the 5 shapes of the front bumper onto a piece of Aluminium sized to suit the flattened pattern of the bumper.


Using a pencil draw on the aluminium 2 horizontal guidelines to match the upper and lower limits of the bumper.

Step 2: Creating the Reliefs using Guides



Guide Block: Using a piece of timber cut out a circle and square hole to match the drawings on the aluminium. [to make a square hole, drill out the 4 corners with a small drill and then use a chisel to gouge out the middle, the depth doesn't matter].

Clamp the aluminium to the guide block and place a blank block on either side of the intended relief area to avoid warping. Using a dowel and a square piece of timber (you may have to make these is if you cannot find them in the workshop), gently hammer the dowel into the circle shape and the square into the corresponding square shape.

Finish up the shape by using the appropriate tool with the sandbag as support.






As the shape is mirrored on the opposite side of the car, simply flip the guide block over and repeat for the other two headlights.

Using a bandsaw, cut out a rectangular shape to match the middle shape of the bumper.


Much like before, align the aluminium sheet and clamp down to avoid warping. As seen in the image below, sometimes warping is unavoidable.


To straighten out the warping, use a thin flat piece of timber on a flat surface with the bumper facing down.


Step 3: Bending the Outer Rim





Using a large round block of timber lean the bumper on a angle that matches the angle of the hood. Using a flat nylon hammer hit the edge of the bumper to create a bent edge on an angle. Start to fold the under side of the bumper to match the line of the adjacent fenders. This is done in a similar way.







Constantly check the angle of the top edge so that it sits snuggly on the buck, and under the hood. Once you are happy start to bring the edges around to meet. Using a sharp timber support, create the side edges to fit under the two fenders. 







Step 4: Fitting to the Car

As the aluminium is soft due to annealing simply twist and tweak the shape to fit under the other pieces. As seen in the left photo the hood fits on top of the bumper with a close gap. 

Reflection - Relief Bumper in the context of Conceptual Product Designs

Depressed Metal Product Designs


I am in my final year of Industrial Design. This course has helped me to understand metal better and how materials work when exposed to different forces. Although beyond the scope of this course I wanted to share the models I made for my Final year studio. I made 4 aluminium models to represent the possible shapes of an adaptive sofa. Below are some images of these models. 





To who ever is marking this.... thank you for an enjoyable semester and see you around the workshop!

Assignment 2: The Ferrari 250 GTO

Ferrari 250 GTO Hood and Bumper Assignment 1: The Hood Dividing the Buck After processing the STL file in Slicer for Fusion360 we carefully assembled our buck in order to ensure accuracy and precision. We held it together with small nails and tape. We also created a wooden base in order to achieve the curves on the underside of the some of the parts (front and rear fenders).  We masking tape to help us understand the curves and shapes of the car. This was also in an effort to split the car up in the best and most true to original way. This ended up not being sufficient so I 3D printed small models of the car with high detail to help understand the curves (see below). We used images of the car's manufacture in Italy and closeups of the unpainted body to split the car into 7 pieces.  We split the car based on aesthetic qualities as well as where we believe the car would have split lines due to functionality. For example, the door, the hood and the windows.  M

I was so excited about the blister that I forgot to take photos until I started cutting it into the shape I wanted.  Nonetheless I managed to make a deep and uniform blister that I discovered would act perfectly as a mothers day gift for my mum (a spoon rest for next to the stove). The finished spoon rest. Yum.
