Perhaps one of the most appealing things about 3D printing using FDM technology is the degree of control that the technology offers to the user. Not only do you have the freedom to select which filament material to use for any given 3D model, but you can also modify the model to suit your needs.
.
One aspect of a 3D model that you can modify is the “shell.” Simply put, the shell is the wall of a 3D printed object. They are an essential part of the design and determine many of the characteristics of the final print. What’s the best shell thickness to use and what factors need to be considered in selecting a shell thickness? What are 3D printing shells? It may not be immediately obvious, but most objects 3D printed in FDM are mostly hollow inside. This is a measure that saves on costly filament material […]
