Prototype to Fabrication Week 2: Making It

Chapter 4: Injection Blow Molding

As was my thought process when entering this course, it is not only extremely intriguing to understand how objects are made, but it is also extremely important. Injection Blow Molding caught my eye immediately for this reason. I was impressed by the simple nature of it, the injection molded preform is lowered into the old then blown into like a balloon. and yet such a simple process causes very serious and large scale implication for our planet. The book is right to highlight the pop bottle as it’s main focus for this section of chapter 4, I would imagine they are ubiquitous with this process. Injection Blow Molding is used to make an incredibly large volume of plastic bottles that “litter our urban landscape,” and the damage that this process creates is certainly part of our educational zeitgeist. Everyday I am aware of the backlash to this type of product. On the design side, I was especially impressed by the Injection-Molded preform that is inserted into the old – often the most ingenious of processes are the most simple.

Chapter 6: High-Pressure Die-Casting

Die-Cast cars, part of my childhood growing up. It sounded cool, they looked cool, they felt cool. I had no idea how my Matchbox or Hot-Wheels cars were made and it is extremely interesting that the process is in the name to begin with. Now that I think about it, a lot of products use their procession method in their name to make them sound very industrial and special:

Chapter 7: InkJet Printing

I was very happy to read in this section that Lefteri acknowledges InkJet printing for its DIY capabilities. The edible menu printing made me think of my own ink cartridge hack of widening (destroying) the holes on the bottom chip side of the cartridge. It made for some messy art projects and misfires from the printer – but the results were very cool looking. One thing the book does not make note of is the high amount of cartridges that are disposed of in landfills each year. Similar to the Pop Bottle, these items are made in incredibly high quantities and are not made to be reused (easily*).

*Refilling printer cartridges is a criminally underused practice. It should be sought after to have consumers buy one set of cartridges over the lifetime of their printer.
