Initial Prototyping Defining The Production Method Having decided upon a pattern I will implement in my design, I still needed to come up with a suitable material and technique for making it into a real backpack. Hence I began making technological prototypes in order test various already existing manufacturing processes and potentially develop some of my own.
Plastic Pressure Forming
I began by experimenting with semi-rigid materials like plastic. Iâ€™ve made a two part plaster mould an a silicon mould to press on heated plastic sheet with. The material however onyl got pierced instead of being formed as apparently it was too stiff to crease.
