In 3D printing, the term “infill” refers to the structure that is printed inside an object. It is extruded in a designated percentage and pattern, which is set in the slicing software. Infill percentage and pattern influence print weight, material usage, strength, print time and sometimes decorative properties.
The strength of a design is directly related to infill percentage. A part with 50% infill compared to 25% is typically 25% stronger while a shift from 50% to 75% increases part strength by around 10%.
There is a wide variety of color and material options available.
Including materials infused with real Bamboo, Copper, Steel and even Carbon Fiber.
(Pricing does differ when using higher grade materials. )
Larger products can be produced in sections and assembled. Items can also be reduced in size for prototyping or preference,
Here is an example, one individual printed a life size Jabba The Hutt using sections. To see that model check out https://www.thingiverse.com/thing:3103238
