Face-Centered Cubic Unit Cell (truncated)

thingiverse

This is a three-dimensional representation of a face-centered cubic unit cell that showcases the inclusion of partial atoms within the standard unit cell. Designed for use in chemistry or materials classes, this model aims to facilitate students' understanding of crystal structures by visualizing their 3D composition. A suggested application for this model involves printing multiple copies, allowing them to be stacked and used as a tangible representation of how individual unit cells contribute to forming extended lattices. Instructions: To replicate the provided design, users should opt for printing it with two layers (or shells) and set their infill percentage to 10%. It's crucial to remove any local support structures after printing using wire cutters; I found this to be most efficient. To enhance stability, additional cylinders have been placed between individual spheres, significantly increasing their surface area in contact.
