Before we begin: The aim of this short study was to decrease the weight/material of our 3D models (the hand). We have successfully printed a hand (link) however it was too heavy. If the hand was lighter, it will be more portable and easier to make future add-ons (such as wrist or arm).
In this post we will introduce the terms 'shells' and 'infills'. We believe that we can significantly reduce the weight by removing the unnecessary material inside 3D models.

The SHELLS, also known as perimeters, are extruded outlines defining the shape of the layer. Extra shells strengthen objects.
INFILL is what happens in the space left over.
It's usually extruded in some kind of pattern. The main setting we're dealing with here, though, is infill percentage. (refer to the image below)
More infill will make an object stronger. Less will make it lighter and quicker to build.
Objects for display often won't need more than 10% infill, while even objects that are going to see hard use rarely need more than 80% infill. Not using more infill than necessary will help us save time and plastic.
