Many have wished to be able to fabricate plastic models of their 3D designs, and many do not have access to rapid prototyping machines or cnc millers. And many do not want to pay 10 dollars a cubic inch of plastic prototyped.
This instructable will introduce my method of fairly rapid prototyping with sheets of abs plastic, no special machines required.
Step 1: Precursor
Many people who design 3D models on their computer would probably like to fabricate them in some sorta material. Other's design solely for the purpose of creating a part and getting it casted. I am part of the later.
This instructable started from my need to create a custom case for my tablet pc. I wanted to house certain components with the tablet and thus, I could not have used any typical case made for my tablet model.
Like many people, I resorted to finding places where I can get the parts milled or printed. And like most people, I was disturbed about the high costs for materials and production. And thus, I sought out an easy way to prototype parts cheaply without the need to produce my own fabber machine.
I have came up with a slue of methods, all of which I summarize by calling it the Origami Prototyping Method.
The key points of this method is to use plastic sheets as if paper, and produce papercraft equivalents of the 3D models.
This instructable goes over the basics and certain key points about this method.
