Personal Logo Model
Foundations of Product Realization - Spring 2019
Create a personal logo with emphasis on ideating processes and rapid prototyping skills.
Concept Sketches
In my initial sketches, I ideated different ways to incorporate my initials into geometric forms, as I had been inspired by the beauty of golden triangles after doing research for a previous quilting project.
My later sketches included more 3D forms, and thought about how I could make my logo be a useful tool as well - settling on a stamp.
The stamp, modeled after hanko, or traditional Japanese name seals, seemed like the perfect object to capture my logo.
Prototypes
I started off my prototyping process by implementing the logo I settled on in various mediums - even sewing patches with some fabric in my dorm.
I later used paper and pink foam to prototype the various 3-dimensional shapes that I was considering. I first created prisms and pyramids with hexagonal faces, but eventually fell in love with a prismatoid with equilateral triangle faces and a hexagon cross section.
Digital Files - creating the prismatoid
I initially attempted to create my prismatoid shape by lofting two triangles together, but I soon found that, even with guide curves, I was unable to create the shape I desired. I went on to create multiple planes that aligned with each side and point of the face triangles, then extruded the faces of triangles I sketched onto my angled planes and made extruded cuts to get rid of the excess matter.
Digital Files - creating the logo
I inscribed my logo within a hexagonal cross section of the prismatoid shape, using a general rule of thumb that all the spaces would be the same width, and leaving a gutter for the other half of the prismatoid to fit into.
Failure Modes
Failure mode 1:
not accounting for fit
When I first made the lid for the stamp, I made the it .04'' thick, which I figured would fit in the .05'' groove. However I found that once the print was done, the pieces did not fit together. I reprinted, with a lip width of .025'' instead, and it fit like a glove!
Failure mode 2:
not accounting for scale changes
When I printed my stamp at 50% scale, it came out with multiple build inaccuracies including globs of plastic attached to the sides of the base, and no lip printed on the lid at all, likely due to my neglecting to check the minimum thickness requirements of the machine.
