For the plasma cutting assignment, I employed three methods, as specified in the beginner’s assignment. I plasma-cut two diamonds with a sakura shape in the middle, angle-grinded them,  sandblasted them, and spray-painted them in a glossy pink.

The cost of creating these two diamonds can be calculated by adding up the cost of materials: The steel sheets (approximately 5″x 3″ in width x height, two diamonds = approximately $1), the white primer (approximately $1 used), and the pink gloss spray paint (approximately $1 used). This equals $3 on two diamonds in materials.

The cost of equipment is negligible, as the equipment is often used by various OEDK students and teams. The plasma cutter is approximately $38000 online, the angle grinder is approximately $200, and the sandblaster is approximately $2000. The diamonds took approximately 3 hours to make, equalling $65.46 total according to the MIT living wage calculator in Texas, and $21 total according to the legal Texas minimum wage.

The total cost of production is equal to approximately $24.75 according to the legal Texas minimum wage, or $68.46 according to the MIT living wage calculator.
