3D printing definitions: G – L

G

G-code – a standardized machine language that instructs a 3D printer how to move, extrude material, and control temperature during the printing process. Generated by slicing software from a 3D model.

I

Infill – the internal structure printed inside a 3D model to provide strength, support, and stability. It is typically defined by a percentage and pattern, affecting part weight and print time.

L

Layer – a single horizontal cross-section of a 3D printed object, deposited sequentially during the printing process. Layers stack on top of each other to form the final part.

Layer height – the thickness of each individual layer in a 3D print, measured in millimeters or microns. It directly affects surface quality, print speed, and level of detail.
